老年人牙缺失后的组织特点及修复设计

老年人由于本身的生理特点以及缺牙的时间较长、缺牙的数目较多等诸因素 ,通常表现为更复杂的牙齿排列及咬合状况。这就决定了修复不仅仅是单纯的缺牙“镶补”,而应该十分重视修复前的口腔检查、资料分析及术前处理 ,合理的设计和适度的恢复咀嚼功能。这样 ,可促进和维持口腔组织健康 ,至少不造成口腔组织的长远性损伤。1　老年人牙缺失后口腔组织临床特征的有关几个问题老年人随着年龄的增长 ,体内各种组织器官相对处于逐渐退化状态 ,表现为肌力减弱、皮肤粘膜弹性降低 ,腺体分泌减少等 ,除此之外 ,口腔内牙列与咬合也存在一定的特点。1.1…

Teeth, tooth spaces, and prosthetic appliances in elderly men in Malmö, Sweden

Abstract A group of 483 men, all of whom were 68 or 69 yr old and had lived for a long time in the city of Malmö were examined with regard to number of teeth present, removable dentures, fixed bridges, and tooth spaces. 76.4% had one or more natural teeth remaining, 59.2% had removable dentures, and 0.2% were edentulous and without dentures. The mean number of teeth present in a fixed dentition calculated on dentate subjects was 16.21 ± 8.02, including teeth replaced by pontics and 15.0 ± 7.44 when natural teeth only were recorded. The number of bridges was high, 28.8% of natural dentate persons having bridgework. This cohort had fewer remaining teeth than in similar groups in other areas of Sweden, but more fixed bridges. 19.5% had open tooth spaces corresponding to one or more teeth in the visible parts of the dental arches. The availability of dentistry has been extremely good in Malmö and financial support for all types of dental care has been provided for all inhabitants since 1974. In spite of this, a low number of remaining teeth and many untreated tooth spaces in visible part of the dental arches were found, though on the other hand much fixed bridgework was found. It appears from the present study that the population tends to polarize into two groups, namely one group which takes advantage of the dental services and one which does not.     

The usefulness of psychometric tests in dental treatment of patients aged above 65

Objective. The aim of this study was to analyze the occurrence of some psychological disorders in elderly people in three different social settings and to evaluate the impact of those problems on the adaptation of denture wearers to removable prostheses. Materials and methods. The study was conducted in three social settings: the geriatric clinic of a university hospital, nursing homes and a Third Age University school (TAU). Each group consisted of 70 randomly selected individuals. Of the total number of 210 subjects, 183 persons wore maxillary removable dentures while 150 had mandibular prostheses. Some symptoms of psychological disorders were diagnosed on the basis of results provided by two tests: GHQ and GDS. For identification of an inter-relationship between the use of removable dentures and the psychic status, the difficulties in adaptation to removable dentures were evaluated. Results. Statistical analysis showed that the number of individuals with depressive symptoms was significantly lower in the group of TAU students than among the nursing home residents. No statistically significant difference in the occurrence of depression was found between the group of hospital patients and the students of TAU. A comparison of the GDS test results with the incidence of denture use difficulties indicated a significant inter-relationship. Conclusions. The GHQ and GDS tests may prove useful in the prosthetic treatment of those removable denture wearers who complain of oral discomfort without manifesting any visible causes. The proportion of elderly with signs of psychic disorders is significantly lower among TAU students than nursing home residents and hospital patients.

目的探讨第二双尖牙先天缺失时合适的治疗方法。方法分析总结2000—2008年治疗的14例第二双尖牙先天缺失患者的临床资料,并结合国内外相关文献,寻找第二双尖牙先天缺失病例合适的治疗方法。结果14例患者中13例选择正畸关闭牙间隙矫治,完成时间为18～36个月,平均27个月,矫治后上下牙列排列整齐,前牙覆、覆盖正常,尖牙中性关系。1例选择集中间隙镶牙的治疗方法,矫治时间10个月。矫治后曲面断层片显示牙根平行,缺牙区牙槽骨无缺损、吸收。结论第二双尖牙的先天缺失应及早发现,并给予适当的治疗,如果患者选择正畸关闭牙间隙的矫治方法,要注意前牙支抗的严格控制,以防破坏侧貌的丰满度。     

Prosthetic treatment need in a representative German sample

Regarding declining resources epidemiological data on needs for oral rehabilitation are required. Within the framework of an oral health survey a non-stratified two-stage random sample was taken to represent the over 14-year-old population of Saxony/Germany. The participation rate was 55%. Normative need was determined by dental assessment and guidelines developed in a consensus process, subjective prosthetic treatment need by self-complete questionnaire. About 97% of the realized sample could be planned within the guidelines. About 81% had normative prosthetic treatment need. Compared with the rate of normative need the rate of subjective need (13%) was considerably lower (chi(2) P < 0;01). Different predictive parameters of subjective need were identified by logistic regression. Besides other factors subjective need was associated with giving dentist's recommendation as significant reason for prosthetic restorations [odds ratio (OR)=5;43], not believing that the own teeth were all right (OR=0;17), and the existence of prosthetic restorations (OR=3;87 for fixed restorations; OR=4;05 for removable dentures). The guidelines proved their suitability to assess normative prosthetic treatment need in oral health surveys. Further research is necessary to find adequate options for including patients' preferences in an adequate need definition.

Associations between missing teeth with unmet needs and socioeconomic status among South Korean dentate government employees

OBJECTIVE: This study aims to examine associations between missing teeth with unmet needs (MTUN) and socioeconomic status, represented by income and place of residence. METHODS: The National Health Insurance Corporation dataset of 822,325 dentate Korean government employees' dental examinations results, questionnaire responses in the year 2000, and basic information collected for administrative purposes was used for this analysis. The main outcome variable was the number of MTUN, categorized into three groups: none, 1-2, and > or = 3. Explanatory variables were assessed and a multinomial logistic regression was employed. RESULTS: Seventy percent were men, with a mean age of 39.1 years (range 18 to 74). The mean number of MTUN was 0.34, and 19.1 percent had > or = 1 MTUN. After adjusting for other variables, age and income were the most salient independent predictors. Rural residents, men, older adults, persons having smoking experience, and persons visiting a dental clinic in the past year were more likely to have >1 MTUN than their counterparts. People performing frequent toothbrushing or having received professional scaling in the past year were less likely to have > or = 1 MTUN than their counterparts. CONCLUSION: Among South Korean government employees with a general dental care insurance benefit, exclusive of prosthetic services, having normative unmet prosthetic need was significantly associated with older age, lower income, and rural residence, taking into account other demographic factors, personal health practices, and dental service utilization.     

Orthodontic Treatment and Implant‐Prosthetic Rehabilitation of a Partially Edentulous Patient

This article describes the treatment of a 61‐year‐old man who had a completely edentulous maxillary arch and partially edentulous mandibular arch. The patient was orthodontically treated to correct an anterior crossbite by distalization of the mandibular teeth using a removable prosthesis serving as an anchorage unit. Subsequently, the patient received two zygomatic implants, five conventional implants in the maxillary arch, and six conventional implants in the mandibular arch. By the end of treatment, the convexity of the facial profile improved, and esthetic and functional occlusion was established.
