A longitudinal clinical trial involving 103 subjects was undertaken to assess the impact of oral implant therapy on the psychosocial well-being of subjects with complete denture wearing problems. There were four experimental groups: (1) an implant group, where subjects were edentulous/edentate in one jaw and requested and received implants to retain an oral prosthesis (IG); (2) subjects edentulous/edentate in one jaw requesting implants but who received conventional dentures (CDG1); (3) edentulous subjects requesting replacement of their dentures by conventional means (CDG2); (4) dentate subjects requiring routine treatment, who were included for comparison. Data were collected in each group pre- and post-treatment using validated oral specific [the Oral Health Impact Profile (OHIP)], and generic (the SF36) health status measures. Subjects in IG, CDG1 and CDG2 also completed a denture satisfaction scale. IG and CDG1 subjects reported that tooth loss and denture wearing problems had a much greater impact on their quality of life than subjects seeking conventional dentures. Dentate subjects had a much better oral health status compared with denture-wearing subjects. Following treatment, subjects who received implant-retained prostheses (IG) reported a significant improvement in satisfaction and health-related quality of life, as did subjects who requested and received conventional dentures (CDG2). Subjects who requested implants, but received conventional dentures (CDG1), reported little improvement in denture satisfaction and only modest improvement in their quality of life. None of the denture-wearing subjects reported health-related quality of life that was as good as that of dentate subjects. The findings have significant implications in the assessment of outcomes in future clinical trials.  相似文献

Patient-based assessment of oral health outcomes is of growing interest. Measurement of change following clinical intervention is a key property of a health status measure. To date, most of the research on oral health status measurement has focused on construct and discriminant validity of health status measures. OBJECTIVES: The objective of this study was to assess sensitivity to change of an oral-specific health status measure, the Oral Health Impact Profile (OHIP). METHODS: Study subjects were in three groups, namely, edentulous/edentate subjects who requested and received complete implant stabilised oral prostheses (IG, n=26), edentulous/edentate subjects who requested implants but received conventional dentures (CDG1, n=22), and edentulous subjects who had new conventional complete dentures (CDG2, n=35). Data were collected pre- and post-operatively using the OHIP and a validated denture satisfaction questionnaire. RESULTS: All subjects reported similar low levels of denture satisfaction pre-operatively. Denture problems had a more significant impact on oral health-related quality of life (OHRQL) for implant seekers (IG and CDG1 subjects) than subjects seeking conventional dentures (CDG2). Following treatment, significant improvement in satisfaction with oral prostheses and OHRQL was reported by IG and CDG2 subjects; the level of improvement was more moderate for CDG1 subjects. OHIP change scores were correlated with denture satisfaction change scores. CONCLUSIONS: It was concluded that sensitivity to change of the OHIP was good. This property was not improved by using statement weights.  相似文献

STATEMENT OF PROBLEM: Outcomes of oral implant therapy have been described primarily in terms of implant survival rates and the durability of implant superstructures. Reports of patient-based outcomes of implant therapy have been sparse, and none of these studies have used oral-specific health status measures. PURPOSE: This study assessed the impact of implant-stabilized prostheses on the health status of complete denture wearers using patient-based, oral-specific health status measures. It also assessed the influence of preoperative expectations on outcome. MATERIAL AND METHODS: Three experimental groups requesting replacement of their conventional complete dentures completed an Oral Health Impact Profile (OHIP) and a validated denture satisfaction scale before treatment. One group received an implant-stabilized prosthesis (IG), and 2 groups received new conventional complete dentures (CDG1 and CDG2). After treatment, all subjects completed the health status measures again; preoperative data were compared with postoperative data. RESULTS: Before treatment, satisfaction with complete dentures was low in all 3 groups. Subjects requesting implants (IG and CDG1) had high expectations for implant-stabilized prostheses. Improvement in denture satisfaction and OHIP scores was reported by all 3 groups after treatment. Subjects who received their preferred treatment (IG and CDG2 subjects) reported a much greater improvement than CDG1 subjects. Preoperative expectation levels did not appear to influence satisfaction with the outcomes of implant therapy in IG subjects. CONCLUSION: Subjects who received implants (IG) that replaced conventional complete dentures reported significant improvement after treatment, as did subjects who requested conventional replacement dentures (CDG2). The OHIP appears useful in identifying patients likely to benefit from implant-stabilized prostheses.  相似文献

PURPOSE: The purpose of this study was to compare elderly patients' satisfaction and oral health-related quality of life with mandibular two-implant overdentures and conventional dentures. MATERIALS AND METHODS: Sixty edentulous subjects aged 65 to 75 years were randomly assigned to two groups treated with maxillary conventional dentures and either a mandibular conventional denture (n = 30) or an overdenture supported by two implants with ball retainers (n = 30). Subjects rated their general satisfaction, as well as other features of their dentures (comfort, stability, ability to chew, speech, esthetics, and cleaning ability), prior to treatment and 2 months postdelivery. Changes in ratings on the original Oral Health Impact Profile (OHIP) and its short form (OHIP-EDENT) were also used as indicators of oral health-related quality of life. RESULTS: The primary outcome of this study, ratings of general satisfaction 2 months postdelivery, was significantly better in the group treated with mandibular two-implant overdentures (P = .001). In addition, the implant group gave significantly higher ratings on comfort, stability, and ability to chew. Furthermore, using OHIP-EDENT, subjects who received mandibular two-implant overdentures had significantly fewer oral health-related quality of life problems than did the conventional group. CONCLUSION: These short-term results suggest that mandibular two-implant overdentures combined with maxillary conventional dentures provide better function and oral health-related quality of life than conventional dentures.  相似文献

PURPOSE: The purpose of this study was to compare clinicians' ratings of the state of oral tissues and their satisfaction with treatment to edentulous patients' ratings of treatment success after provision of mandibular implant overdentures or conventional dentures. MATERIALS AND METHODS: Sixty subjects randomly received either mandibular overdentures retained by two implants (n = 30) or new conventional mandibular complete dentures (n = 30). All were given new conventional maxillary dentures. Baseline measures included clinical evaluation of the oral soft and hard tissues. Patients rated their general satisfaction before and after treatment, as well as their satisfaction with stability, speech, and esthetics on visual analogue scales. The treating prosthodontist rated the dentures for the same categories. Patient and clinician ratings were compared using correlations, t tests, and linear regression. RESULTS: None of the clinical variables were significantly correlated with patient satisfaction before or after treatment. The prosthodontist rated mandibular implant overdentures significantly better than conventional dentures regarding general satisfaction, stability, speech, and esthetics. Implant overdentures were also easier to fabricate (P < .0001). The prosthodontists' scores were not significantly correlated with patient scores for any question. CONCLUSION: Clinicians' assessments of the quality of denture-supporting tissues are poor predictors of patient satisfaction with mandibular implant or conventional prostheses. Prosthodontists and patients both rate mandibular implant overdentures as significantly superior to conventional dentures, but patients and clinicians do not usually agree when evaluating individual prostheses.  相似文献

Objective: The aim of this study was to compare the impact of customised dietary advice on patients' satisfaction with their dentures and oral health‐related quality of life (OHRQoL) in patients wearing implant‐supported mandibular overdentures (IOD) or conventional dentures (CD). Materials and methods: In this prospective cohort study, 28 IOD (two implant‐retained mandibular overdenture) and 26 CD patients completed a denture satisfaction scale and the 20‐item oral health impact profile (OHIP‐20) before and 6 months following provision of customised dietary advice. Results: At 6 months following provision of individualised dietary advice, the IOD group showed significantly greater satisfaction than the conventional group for denture comfort (80.6, ± 15.6, vs. 68.7 ± 15.6 P=0.001), stability (75.8 ± 15.9 vs. 59.5 ± 30.4, P=0.002), and perceived chewing ability (79 ± 30.4 vs. 59.5 ± 30.4, P=0.027) ± when adjusted for baseline scores. Before delivery of the dietary advice there were no significant differences between groups for Satisfaction or OHIP scores. No difference in OHRQoL was seen between groups. Conclusions: The delivery of customised dietary advice to edentulous patients impacts differently on their satisfaction with denture comfort, stability and chewing ability depending on the nature of their prosthesis. This re‐evaluation of satisfaction occurs when edentulous patients challenge themselves to consume more fruits, vegetables and fibre‐rich foods. The IOD group reported an increased level of satisfaction and perceived chewing ability whereas it appeared that CD wearers may have had their awareness of the shortcomings of this sort of prosthesis reawakened.

The importance of assessing the impact of treatments for chronic conditions on an individual's quality of life has been well-established. In this randomized clinical trial, oral-health-related quality of life, measured with the Oral Health Impact Profile (OHIP), was compared between two groups of edentulous patients. One group (n = 54) received mandibular implant-supported overdentures, and the other group (n = 48) received conventional dentures. Assessments were performed pre-treatment and two months after the prostheses were delivered. The multivariate model showed that implant treatment was significantly associated with lower post-treatment OHIP scores (p = 0.0002), indicating a better quality of life. In addition, pretreatment OHIP scores, treatment allocation, age, sex, and marital status explained 31% of the variation in post-treatment OHIP scores (F = 0.0001). These results suggest that implant treatment provides significant short-term improvement over conventional treatment in oral-health-related quality of life.  相似文献

Oral stereognosis was measured in partially dentate and edentulous patients with stroke, Parkinson's disease, and an age and gender-matched control group. Stereognostic tests involving conventional free intra-oral manipulation of test objects were undertaken in the partially dentate and edentulous with and without complete dentures. Comparisons were made using the unpaired t-test and ANOVA. Edentulous stroke patients without dentures had significantly greater error scores and fewer correct identifications compared with partially dentate stroke patients. Stereognostic measures were similar in the partially dentate and edentulous with dentures, within experimental groups. In the partially dentate, there were no differences in stereognostic measures between the three groups. Stereognostic measures were poorer in edentulous stroke patients with and without dentures compared with the edentulous control group. Partially dentate stroke patients are less likely to have impaired oral stereognosis than edentulous stroke patients.  相似文献

Oral status and nutrition in the institutionalized elderly.   总被引:1,自引:0,他引:1  
OBJECTIVES: To evaluate, in an elderly population, whether poor oral status might be a contributing factor to the development of undernutrition and might be associated with less eating pleasure, more subjective eating difficulty and increased mashed food consumption. METHODS: An oral examination and an evaluation of masticatory capacity were performed on 120 institutionalized elderly subjects. The nutritional assessment included serum albumin concentration, the Mini Nutritional Assessment and a questionnaire on eating habits. RESULTS: Edentulous subjects without dentures or with only one complete denture had significantly lower MNA scores than edentulous subjects with two complete dentures (p < 0.05). Edentulous subjects with two complete dentures more frequently reported taking pleasure from eating (p = 0.05), and had less frequent difficulties with hard foods (p = 0.01) than edentulous subjects without dentures or with only one complete denture. Mashed food consumption (p < 0.01) was also reported more frequently in edentulous subjects without dentures or with only one complete denture. Subjects with two complete dentures had similar or better MNA scores as dentate subjects with relatively few remaining teeth (10.4 +/- 7.8 teeth). About half of the subjects (53%) could not perform the masticatory test. These subjects had lower MNA scores (p = 0.001) and a larger proportion ate mashed food (p < 0.001) compared to those who were able to perform the test. CONCLUSIONS: Poor oral status (edentulous without dentures or with only one complete denture) increased difficulty in eating hard foods, increased mashed food consumption and decreased eating pleasure. It seemed also to put institutionalized subjects at higher risk of undernutrition.  相似文献

PURPOSE: This study examined patient satisfaction with conventional complete dentures and mandibular implant overdentures opposing conventional maxillary dentures 6 months after delivery. MATERIALS AND METHODS: Sixty edentulous subjects (aged 65 to 75 years) were randomly assigned to either a mandibular conventional denture or an overdenture supported by two implants with ball-shaped retentive anchors. Patients rated their general satisfaction and other features of their prostheses, together with their ability to eat certain food items, on 100-mm visual analogue scales before assignment, and after 2 and 6 months. RESULTS: Both treatment groups reported greater satisfaction with their new prostheses at 6 months. General satisfaction ratings were higher in the implant group than in the conventional denture group by approximately 36% (mean difference 22.3 mm). The implant group also rated comfort (mean difference 22.4 mm), stability (mean difference 28.5 mm), and ability to chew (mean difference 17.3 mm) significantly higher. Significantly higher scores were also given by the implant group for their ability to chew certain hard foods. A trend for an increase in the differences between the groups, in favor of the implant group, was observed between the 2- and 6-month recalls, although the increase was only significant for ease of cleaning. The primary influence on general satisfaction 6 months after the delivery of the prostheses was the provision of the two-implant overdenture. CONCLUSION: Edentulous seniors who received mandibular implant overdentures opposing a conventional denture rated their general satisfaction approximately 36% higher than did a comparable group provided with new conventional dentures.  相似文献

The loss of natural teeth compromises chewing efficiency, and edentulous patients often have a diet that is deficient in fibre and vitamins. Prostheses that are retained on implants offer the possibility of overcoming some of the limitations of conventional dentures in terms of chewing efficiency. The aim of this study was to test the hypothesis that improvement in satisfaction with oral prostheses would result in improved food selection in edentulous patients. This prospective study involved three groups, namely (i) subjects who requested and received implants to stabilise a complete fixed or removable prosthesis (IG, n = 26), (ii) edentulous subjects who requested implant prostheses, but received conventional dentures (CDG1, n = 22), and (iii) edentulous subjects who requested and received conventional dentures (CDG2, n = 35). Data were collected using validated questionnaires pre- and postoperatively. Prior to treatment, all subjects were asked whether they ate a variety of hard and soft foods, to indicate the degree of difficulty they experienced when chewing these foods, and to rate their satisfaction with various aspects of their maxillary and mandibular complete dentures. Following the completion of treatment, subjects completed the questionnaires again. Pre- and postoperative data were compared. Subjects who received implant prostheses reported significant improvement in chewing hard and soft foods. CDG2 subjects also reported improvement, but CDG1 subjects reported no change or even deterioration following treatment. Despite reported improvement in satisfaction with comfort and ability to chew food, 30-50% of IG and CDG2 subjects still avoided eating foods such as carrot and apple. This suggests that, in the absence of tailored dietary advice, apparently successful prosthetic rehabilitation does not necessarily result in a satisfactory diet.  相似文献

DESIGN: This was a randomised controlled trial (RCT) set in a dental hospital. INTERVENTION: The implant group (IG) had two implants placed in the interforaminal region of the lower jaw followed (after healing) by a denture fixed to the implants by a ball attachment mechanism. In the conventional dentures group (CG), dentures were constructed using conventional replacement denture techniques. Patients in the IG had conventional upper dentures made in the same fashion. OUTCOME MEASURE: The performance of the dentures was evaluated using an oral health impact profile (OHIP) and a denture satisfaction scale before treatment and 3 months post-treatment. RESULTS: Analysis was conducted on an intention-to-treat basis. Substantial improvements in oral-health-related quality of life and denture satisfaction were reported by both groups. There were, however, no significant differences post-treatment between the groups. Patients randomised to the IG who declined implants had significantly lower pretreatment OHIP scores and there were significantly greater pre-/ post-treatment change-scores for individuals who had implants compared with the change-scores of people who declined. CONCLUSIONS: There were no significant post-treatment differences between the groups, but a treatment effect may be masked by the intention-to-treat analysis. The pre-/ post-treatment OHIP change-scores were significantly greater for people receiving implants than for those who refused.  相似文献

The aim of this study was to determine the association between clinical oral status and oral impacts experienced by older individuals in Sri Lanka. A total of 585 individuals who were above 60 years and were residents of an urban area was selected using a multistage cluster sampling combined with probability proportionate to size technique. However the present analysis is limited to 235 individuals who were subjected to a clinical oral examination. An interviewer administered Sinhala translation of the Oral Health Impact Profile-14 (OHIP-14) scale was used to assess the oral impacts experienced by the sample. An oral examination was carried out following the interview. Of the 235 subjects clinically examined 64 (27%) were edentulous. The associations between clinical parameters and oral impacts were assessed in the 171 dentate subjects. There were positive, weak but significant correlations between the number of missing teeth, the number of teeth with third degree mobility and the OHIP score. Also those who wore dentures and had halitosis had significantly higher OHIP scores than those who did not wear dentures and did not have halitosis. Logistic regression analysis revealed that 'wearing denture' and 'having halitosis' were significant predictors of the OHIP score. In conclusion, there was a weak association between clinical parameters and oral impacts experienced by these older individuals.  相似文献

This study was to validate a mandarin Chinese version of Oral Health Impact Profile (OHIP-49) in China and to develop a shortened version of OHIP appropriate for use in partially dentate patients with implant-supported prostheses. The original 49 items of OHIP were translated into mandarin Chinese using a forward-backward method and administered to 580 subjects selected by stratified random sampling. Self-perceived oral health status and treatment need were also collected. Reliability and validity of the Chinese version of OHIP (OHIP-C49) were validated. A shortened version (OHIP-I) was derived from the OHIP-C49 by exploratory factor analysis (EFA) as well as expert-based approach in partially dentate patients (n=102) with implant-supported prostheses. For validation of the new modified shortened version, another independent sample of 97 partially dentate patients completed OHIP-I and their self-perceived oral health status at baseline and at least 3 months after dental implant rehabilitation. Five hundred and thirty-seven effectual questionnaires were reclaimed from the 580 subjects interviewed. Cronbach's alpha ranged from 0.78 to 0.96 and test-retest correlation coefficients ranged from 0.84 to 0.97 for subscale and summary scores. Construct validity was demonstrated by priori hypothesised associations between the OHIP-C49 scores and self-perceived oral health (P<0.001). The reliability and validity of OHIP-I were similar to which of the OHIP-C49, and the responsiveness appeared able to measure the effect of dental implant therapy effectively. The mandarin version of OHIP-49 showed sufficient psychometric properties for Chinese. The modified shortened version (OHIP-I) may be appropriate for the evaluation of implant therapy outcomes in partially dentate Chinese patients.  相似文献

Implant overdentures and conventional prostheses have been compared in several trials using a variety of functional and oral health-related quality of life (OHQOL) outcomes. In this paper, we describe the impact of implant overdentures on general and OHQOL in seniors. OBJECTIVES: To compare the oral health-related and general quality of life of seniors (aged 65-75 years) who received either mandibular implant overdentures or conventional dentures. METHODS: Sixty edentulous patients were recruited. Thirty received mandibular overdentures retained by two implants (IOD) and a conventional maxillary denture, the other 30 subjects received new maxillary and mandibular conventional complete dentures (CD). All completed the 20-item version of the Oral Health Impact Profile (OHIP-20) before treatment, then at two and 6 months after delivery of the dentures. The SF-36 general health questionnaire was completed at baseline and 6 months only. RESULTS: Pretreatment and 6-month data from 55 subjects were analyzed. Those who received the IODs had significantly better OHIP-20 total scores at 6 months. Results for IOD subjects were also superior in the functional limitation, physical pain, physical disability and psychological disability subscales. While no significant between group difference was found on the SF-36 health survey, significant pre-post-treatment differences within the IOD group were detected for the role emotional, vitality and the social function scales. CONCLUSIONS: Mandibular overdentures retained by two implants provide elderly patients with better OHQOL. General health-related quality of life improved in the implant group.  相似文献

STATEMENT OF PROBLEM: Edentulous patients can have difficulty in tolerating dentures and this may lead to psychologic disturbance. The problem is potentially more severe for edentulous patients after primary surgery for oral cancer, where treatment can include composite resection and reconstruction, followed by adjuvant radiotherapy. PURPOSE: This study investigated the psychologic response and oral satisfaction of edentulous patients treated by surgery for oral squamous cell carcinoma, and to make a comparison to edentulous noncancer counterparts. METHODS AND MATERIAL: The cross-sectional study included patients who were alive and disease-free 2 to 3 years after primary surgery. Seventy patients underwent surgery at the Regional Maxillofacial Unit, Liverpool, in 1993 and 1994. Twenty-eight patients were disease-free; 26 completed questionnaires that included a general health questionnaire (GHQ), a body satisfaction scale, a self-esteem scale, an oral symptom checklist, and a denture satisfaction questionnaire. Comparison was made with 98 noncancer edentulous patients from the same unit. RESULTS: There were similarities in psychologic and oral satisfaction scores between the noncancer and cancer edentulous patients. Cancer patients reported lower self-esteem (P <.02). Cancer patients who were not rehabilitated with either conventional or implant-retained prostheses had significant psychologic morbidity as measured by the GHQ, self-esteem, and body satisfaction scales. Cancer patients with implant-retained overdentures reported greater satisfaction with their dentures compared with their counterparts who wore conventional dentures (P <.05). CONCLUSION: Edentulous cancer patients who do not achieve oral rehabilitation after surgery for oral cancer exhibited significant psychologic morbidity. Patients with implant-retained overdentures exhibited a tendency to adopt the same psychologic response with improved denture satisfaction as edentulous patients with conventional dentures, despite the former having more extensive disease that would otherwise make the provision of dentures much more difficult if implants were not used.  相似文献

OBJECTIVES: Males and females differ in their responses to many health conditions and treatments. The aim of this randomized clinical trial was to determine whether there are differences in the way that male and female edentulous elders rate their satisfaction with new mandibular implant overdentures (IODs) and conventional dentures (CDs), at 6 and 12 months following delivery. METHODS: Edentulous elders (n=256) were randomly assigned to receive maxillary conventional dentures and either mandibular overdentures supported by two implants with ball attachments or conventional dentures. Participants rated their general satisfaction, as well as other features of their dentures (comfort, stability, ability to chew, aesthetics, etc.) prior to treatment and 6 and 12 months after delivery. RESULTS: Ratings of satisfaction with IODs were significantly higher than with CDs. Six months after delivery, females in the CD group rated their general satisfaction and satisfaction with ability to chew and aesthetics significantly lower than did the males. The sex differences in the CD group remained at 12 months after delivery. However, males and females in the IOD group rated their general satisfaction and all six subcategories equally. CONCLUSIONS: Elderly females are less satisfied with conventional dentures than elderly males with regards to aesthetics and ability to chew, but equally satisfied with implant overdentures. At 6 and 12 months after delivery, elderly edentulous males and females wearing mandibular implant overdentures were significantly more satisfied than those wearing conventional dentures.  相似文献

OBJECTIVES: Using the item-impact method, we developed an alternative short-form Oral Health Impact Profile (OHIP) that has good psychometric properties and minimal floor effects. METHODS: OHIP data were collected from a sample of older Canadians at two points in time. Data from the first administration were used to develop a 14-item short-form measure; data from the second compare the latter's psychometric properties with those of the original short form developed by Slade (1997), who used a controlled regression procedure. RESULTS: The short form based on the item-impact method had only two items in common with the short form derived from the regression approach and contained more high-prevalence items. The regression short form was subject to marked floor effects, while the impact short form had floor effects comparable to those of the full 49-item OHIP. The former discriminated between dentate and edentulous subjects, while the latter did not. Both discriminated between dentate subjects who did and did not wear dentures, those with and without dry mouth, and those with and without chewing problems. Both were also significantly associated with self-ratings of oral health, satisfaction with oral health, and self-perceived need for dental treatment. The strength of the associations was somewhat stronger with the regression short form, indicating that it performed better as a discriminatory instrument. However, because of its floor effects, it was markedly less sensitive to change than the impact short form. There was an indication that item-impact methods of shortening oral health-related quality of life measures produced more stable results across samples than the statistical approach. CONCLUSIONS: Because the content validity of short-form measures is always compromised, different short forms are required for different purposes and different patient populations. The regression short form developed by Slade (1997) is likely to be better when the aim is to discriminate, while the impact short form developed here may be preferable when the aim is to describe the oral health-related quality of life of populations or to detect change.  相似文献

There is widespread consensus that the neutral zone (NZ) concept contributes to improved stability for mandibular complete dentures (CDs). However, little is known about its impact on oral health‐related quality of life (OHRQoL) of edentulous patients compared to conventionally (CV) manufactured dentures. In this prospective crossover trial, performed at the Oral Health Centre of the University of the Western Cape, CV and NZ mandibular dentures were made for each patient. Scores from the 20‐item oral health impact profile (OHIP‐20) for both types of dentures were compared with pre‐treatment scores using paired t‐tests. Treatment effect size (ES) was established. Associations of OHIP‐20 scores and several patient variables (age, gender, period of edentulousness, quality of the denture‐bearing tissue, denture dimensions, preference) were performed using the generalised linear model. Significance was set at P = 0·05. Records of thirty‐five participants were included in the study (mean age of 62·3 years, range 47–85 years). There were highly significant differences between pre‐treatment and both post‐treatment OHIP‐20 scores with t = 6·470 for CV and t = 6·713 for NZ. Treatment ES was large for both types of dentures (>0·8). Difference of ES between NZ and CV dentures was small (ES < 0·2). None of the patient variables showed significant associations with OHIP‐20 scores of the two types of dentures, except for preference and NZ OHIP‐20 scores. For this group of patients, both treatment methods improved OHRQoL significantly and patient‐related factors did not influence impact on OHRQoL differently for both interventions.  相似文献

STATEMENT OF PROBLEM: The loss of the natural dentition leads to severe functional impairment in many edentulous adults. A prosthesis retained and supported by osseointegrated dental implants may provide a satisfactory solution for people who have lost all their natural teeth. However, little information is available as to what patients requesting implants expect of implant-retained prostheses. AIM: The aim of this study was to assess the expectations of a group of edentulous patients requesting implant therapy. METHOD: The study included two groups: (1) a group of edentulous adults who requested implant therapy ('implant group'); and (2) an edentulous control group, of similar age and gender distribution as the implant group, receiving conventional complete dentures. Following a clinical and radiographic examination of the patients, data were collected using validated questionnaires. Both groups made a subjective assessment of current dentures. The implant group also completed a questionnaire which assessed expectations of implant-retained prostheses. RESULTS: Baseline satisfaction with current dentures was low in both groups, with the implant group being significantly less satisfied with comfort and stability of their mandibular dentures. Perceived ability of the implant group to chew hard foods was less than the control group. The implant group's expectations of an implant-retained prosthesis were significantly greater than for a conventional denture. CONCLUSION: Careful assessment of patient expectation of implant therapy is essential to determine appropriate treatment need, and to highlight unrealistic expectations.  相似文献
