Purpose
To determine the relationship between the cranial base and both jaw bases in different skeletal patterns.Materials and methods
Lateral cephalometric radiographs of 180 adult patients of all three malocclusion groups were evaluated and analyzed. A group of linear and angular measurements were measured and compared among all study groups to assess the existence of any relationship between the cranial base and both jaw base discrepancies.Results
Significant differences were found in the cranial base angle (NSBa) and both jaw base lengths among all three malocclusion groups, while no significant differences were found in the cranial base lengths. As for angular measurements, an inverse correlation was found between the cranial base angle and both SNA and SNB angles in both Class II and Class III malocclusion groups. Concerning linear measurements, a significant correlation was found between the total cranial base length and the total facial height among all malocclusion groups.Conclusion
The cranial base angle affects the anteroposterior orientation of both maxilla and mandible with a minimal contribution to the appearance of different vertical skeletal patterns. Meanwhile, the cranial base length affects minimally the anteroposterior orientation of both the maxilla and the mandible. However, a significant link was found between it and the total facial height, thus contributing to the appearance of different vertical skeletal patterns. 相似文献2.

Purpose
To assess buccal cortical bone thickness of the alveolar process in the maxilla and mandible in subjects with different skeletal relationship as an aid in orthodontic miniscrew placement.Materials and methods
The study was carried out using cone-beam computed tomography (CBCT) images of 94 adult subjects with skeletal Class I, II or III sagittal relationship and normal mandibular plane angle. Buccal cortical bone thickness was obtained at the alveolar processes from canine to second molar at 2 different vertical levels (6, and 8 mm) from the cementoenamel junction (CEJ). Analysis of variance (ANOVA) was used to analyse differences in cortical bone thickness.Results
The difference in mean values of buccal Cortical thickness was significant between the three skeletal classes in both arches and all sites except for the site between first and second mandibular molars (P < 0.05). In the mandible, buccal cortical plate was thickest between first and second molar in all skeletal classes. In the maxilla, the highest cortical bone thickness for Class I subjects was between first and second molar, for Class II subjects was between canine and first premolar, and for Class III subjects was between first and second premolar. Mandibular measurements increase apically and posteriorly in all skeletal classes.Conclusions
Buccal cortical bone thickness could be influenced by skeletal relationship. The mandible shows a similar pattern for all skeletal classes. In the maxilla each skeletal relationship shows a different pattern. Skeletal relationship need to be considered in site choice for miniscrew placement. 相似文献3.

Purpose
Evaluate how clinical factors related to conventional complete denture (CCD) wearers, can influence masticatory function (MF) of totally edentulous patients before and after one-year transitioning to implant-retained mandibular overdentures (IMO).Methods
Forty patients using CCD were rehabilitated with IMO and their MF was evaluated by: (i) ST_X50: theoretical aperture through which 50 % of the weight of the particles would pass; (ii) STB: distribution homogeneity of the crushed particles. The clinical parameters analyzed were: atrophy, retention, stability, facial type, anteroposterior skeletal discrepancy, and type of loading. The statistical association was tested through crude and adjusted logistic regression.Results
IMO promoted improvements in the MF, irrespective of the clinical parameters. CCD wearers with poor retention had 86 % less chance of achieving a good ST_X50. STB was associated with stability, facial type, and anteroposterior discrepancy. Subjects with poor mandibular CCD stability had a 76 % lower chance of achieving a good test food homogenization, whereas brachyfacial individuals were 1.3 times more likely to have a good STB. Class II patients had an 89 % lower chance of having a good homogenization of the particles as CCD users and after transition to IMO.Conclusions
CCD users with poor retention achieved an inferior ST_X50. The STB performance can be compromised by poor stability or Class II characteristics, while brachyfacial individuals achieve better homogenezation of the food bolus. Although the transition to IMO improved the masticatory function, the anteroposterior discrepancy still maintained an association with STB, as Class II individuals still presented difficulties homogenizing food. 相似文献4.

Four premolar extractions is a successful protocol to treat Class I malocclusion, but
it is a less efficient way when compared with other Class II treatment protocols.
Objective:
The objective of this study was to evaluate the influence of anteroposterior discrepancy on the success of four premolar extractions protocol. For that, treatment efficiency of Class I and complete Class II malocclusions, treated with four premolar extractions were compared.Methods:
A sample of 107 records from 75 Class I (mean age of 13.98 years - group 1) and 32 Class II (mean age of 13.19 years - group 2) malocclusion patients treated with four premolar extractions was selected. The initial and final occlusal status of each patient was evaluated on dental casts with the PAR index. The treatment time was calculated based on the clinical charts, and the treatment efficiency was obtained by the ratio between the percentage of PAR reduction and treatment time. The PAR index and its components, the treatment time and the treatment efficiency of the groups were statistically compared with t tests and Mann-Whitney U-test.Results:
The Class II malocclusion patients had a greater final PAR index than Class I malocclusion patients, and similar duration (Class I - 28.95 mo. and Class II - 28.10 mo.) and treatment efficiency.Conclusion:
The treatment of the complete Class II malocclusion with four premolar extractions presented worse occlusal results than Class I malocclusion owing to incomplete molar relationship correction. 相似文献5.

Purpose
This study has evaluated the pre and post perceptions of patients with ectodermal dysplasia (ED) who have been referred to Westmead Centre for Oral Health for treatment with dental implants.Methods
Six patients with ED and hypodontia were treated with new maxillary complete dental prostheses or fixed implant prostheses, and a mandibular fixed dental prosthesis with implants. Patient perceptions were recorded with a 10 cm visual analogue scale (VAS). All patients were asked to draw a line on the VAS which best described their feelings regarding aesthetics, chewing, diet and speech.Results
Improvement in aesthetics was reported for all patients with change scores ranging from +9 to +4 points. Similarly, all patients reported an improvement in chewing ability with +6 point changes in 2 patients, and +8, +3, +7 and +1 in the other 4 patients. Five out of 6 patients reported less dietary restriction with 3 patients each indicating a change of +6 points, +4 points, +3 points, and 2 patients reporting +1 point change. Speech improved by +1 point for 3 patients, whilst 1 patient improved by +6 points, a further 2 patients scored no change.Conclusions
Patients with ED treated with dental implants reported encouraging outcomes post treatment after prostheses were fitted. Follow-up from 1.6 to 6.8 years has confirmed these improvements. 相似文献6.

Purpose
To determine the ratios of dental and lip changes and develop the predictive equations of lip changes in Class I bimaxillary protrusion in Thai female adults after orthodontic treatment with 4 premolars extraction.Materials and methods
The sample consisted of pre- and post- treatment lateral cephalograms of 91 Thai subjects with Class I bimaxillary protrusion. The ages of the samples were between 17–39 years old (22.57 ± 4.7). These patients had orthodontic treatment with four premolars extraction and retraction of upper and lower incisors. Pre-and post-treatment lateral cephalograms were traced and superimposed by using SN-7° plane. The parameters from cephalograms were measured with digital vernier caliper and cephalometric protractor. Statistical analysis was performed to analyze the dental and lip changes by paired t-test. Pearson’s correlation and stepwise multiple regression were made to determine factors that related with lip changes.Results
Significance antero-posterior changes after treatment were found both in dental and lip analysis but vertical changes were not significant. The correlations were found low to moderate relationship between dental and lip changes in both sagittal and vertical directions. The equations of upper and lower lip changes in sagittal and vertical dimensions were constructed.Conclusion
The ratios of upper and lower anterior teeth retraction and upper and lower lip changes were 1:0.56 and 1:0.87, respectively. The predictive equations of upper and lower lip reductions were ΔH-U-lip = 0.34(ΔH-tUI) + 1.19 and ΔH-L-lip = 0.57(ΔH-cLI) + 2.11, respectively. 相似文献7.

Objectives
This study aimed to develop a method to induce carious lesions in the pulpal floor dentin of a class II cavity preparation, and to determine the effects of this carious lesion on the biomechanical behavior of the dental composite restoration.Methods
The pulpal floor dentin of class I cavities in sound third molars were demineralised with acetic acid for 35 days followed by a 7-day exposure to pooled human saliva biofilm and demineralization was verified by micro-CT. Subsequently, the proximal walls were removed forming a class II cavity and the caries lesion was left intact or was completely removed prior to restoration with a bulk-fill dental composite (n = 10). Cuspal deflection was assessed by strain-gauge and micro-CT imaging. The presence of enamel cracks was assessed by transillumination before and after restoration, and again after 1,200,000 cycles of mechanical fatigue in a chewing simulator. Finally, resistance to fracture by axial compressive loading and failure mode was determined. Data were analyzed by 2-way repeated measures ANOVA, Fisher’s exact test, and t-test (α = 0.05).Results
The presence of carious lesions had no significant effect upon cuspal deflection, formation of enamel cracks, and fracture strength of the dental composite restorations. The restorative procedure increased the number of enamel cracks, which was not affected by mechanical cycling.Significance
Maintaining carious lesions does not affect the biomechanical behavior of class II restorations performed with bulk-fill dental composite. 相似文献9.
Purpose
Stable orthodontic treatment results require the preservation of the pretreatment mandibular dental arch form. Therefore, this study aimed to evaluate the amount of transverse adjustment of preformed stainless steel archwires require to fit the dental arch form.Materials and methods
A fourth-order polynomial curve was applied to the 30 normal mandibular dental arches, and interpolated widths at the mean depths at the canine, first and second premolars, and first molar were measured. Widths of 42 types of 0.016-in. stainless steel preformed archwires were measured at the same mean depths. The widths of the dental arch and archwires were compared by the Mann–Whitney U test. Transverse adjustment values as the difference between dental and archwire widths for each tooth from the canine to first molar were calculated for each archwire and compared between tooth types. Correlation coefficients between tooth types were also analyzed.Results
Preformed archwire width was significantly narrower than the dental arch. Significant difference between transverse adjustment values between each tooth type were found except between canine and first premolar. Significant correlations between each tooth types were also observed.Conclusion
To reduce these adjustments, preformed stainless steel archwires that are designed to be approximately 1–2 mm at the canine, 1–3 mm at first premolar, 2–4 mm at second premolar, and 3–6 mm at first molar wider in the transverse dimension could be clinically recommended. 相似文献10.

Purpose
The study simulated a mandibular buccal shelf (MBS) orthodontic anchoring screw insertion path and determine the effect of vertical skeletal pattern, insertion site, vertical level and insertion angle on the slope, cortical bone thickness and distance from molar root to the insertion path.Materials and methods
Forty CBCT images of Class III subjects were divided equally into hyperdivergent and normodivergent groups. The slope of the MBS was measured at four different sites of insertion. Cortical bone thickness along the orthodontic anchoring screw insertion path and distance from molar root to the path were measured at different combinations of sites of insertion, vertical levels and insertion angles. Measured outcomes were compared between hypodivergent and normodivergent groups at different combinations of variables using factorial repeated ANOVA.Results
The cortical bone thickness and the slope of the MBS were not different between hyperdivergent and normodivergent groups. However, posterior sites had a flatter slope than that of the anterior. Higher vertical level and insertion angle resulted in thicker cortical bone and higher distance from molar root. The mesial aspect of second molar site gave a higher distance from molar root than first/second molar contact point site.Conclusion
The mesial aspect of the second molar appears to be a safe site for placement of MBS orthodontic anchoring screw as its slope was flatter and gave greater distance from molar root. Increasing vertical level or insertion angle resulted in a higher cortical bone thickness and distance from the molar root. 相似文献11.
Objective
To modify the resin-based composite (RBC) restoration protocol for standardised Class II cavities in third molar teeth restored using conventional RBCs or their bulk fill restorative counterparts. Employing cuspal deflection using a twin channel deflection measuring gauge (during) and microleakage to determine marginal integrity (following) RBC restoration, the modified restoration protocol results were compared with traditional (oblique) restoration of Class II cavities.Methods
Thirty-two sound third molar teeth, standardised by size and morphology, were subjected to standardised Class II cavity preparations and randomly allocated to four groups. Restorations were placed in conjunction with a universal bonding system and resin restorative materials were irradiated with a light-emitting-diode light-curing-unit. The cumulative buccal and palatal cuspal movements from a twin channel deflection measuring gauge were summed, the restored teeth fatigued thermally prior to immersion in 0.2% basic fuchsin dye for 24 h, before sectioning and examination for microleakage.Results
Teeth restored using conventional RBC materials had significantly higher mean total cuspal movement values compared with bulk fill resin restorative restoration (all p < 0.0001). Teeth restored with Admira Fusion and Admira Fusion x-tra had significantly the lowest microleakage scores (all p < 0.001) compared with Tetric EvoCeram and Tetric EvoCeram Bulk Fill restored teeth. The microleakage scores for the range of RBC materials tested were significantly reduced (all p < 0.001) when the modified RBC restoration protocol was employed compared with the traditional Class II restoration technique.Significance
Modification of the RBC restoration protocol of some conventional RBCs and bulk fill resin restoratives significantly improve bond integrity and could be translated as a validation of the limited clinical studies available on bulk fill materials in the dental literature where Class II cavities perform less well than Class I cavities following extended follow-up.Clinical significance
The results of the current study add further weight to experimental protocols employing cuspal movement (during) and cervical microleakage (following) RBC restoration of standardised cavities in natural dentition to provide an indication of polymerization shrinkage stress at the tooth/RBC restoration interface in a ‘clinically meaningful context’. 相似文献12.

Objective
To determine the osseointegration rate of zirconium dioxide (ZrO2) dental implants in preclinical investigations.Data
Data on the osseointegration rate was extracted considering the bone to implant contact (BIC), removal torque analysis (RTQ) and push-in tests. Meta analyses were conducted using multilevel multivariable mixed-effects linear regression models. The ?idák method was used in case of multiple testing.Sources
An electronic screening of the literature (MEDLINE/Pubmed, Cochrane Library and Embase) and a supplementary manual search were performed. Animal investigations with a minimum sample size of 3 units evaluating implants made of zirconia (ZrO2) or its composites (ZrO2 > 50 vol.%) were included.Study selection
The search provided 4577 articles, and finally 54 investigations were included and analyzed. Fifty-two studies included implants made from zirconia, 4 zirconia composite implants and 37 titanium implants. In total, 3435 implants were installed in 954 animals.Conclusions
No significant influence of the evaluated bulk materials on the outcomes of interest could be detected. When comparing different animal models, significant differences for the evaluated variables could be found. These results might be of interest for the design of further animal investigations. 相似文献13.

Objective
A novel copper-bearing titanium alloy (Ti–Cu) was fabricated for dental application that is expected to efficiently restrain the growth of bacteria and discourage biofilm formation. The aim of this study was to investigate both the antibacterial activity and biofilm inhibition of Ti–Cu alloy in vitro, and the antibacterial effect of Ti–Cu implant in early stage of peri-implantitis in vivo.Methods
Staphylococcus aureus and Escherichia coli were selected to evaluate the antibacterial activity of Ti–Cu alloy and Ti served as control. The antibacterial rate, attached bacteria and developed biofilms were studied from quantitative antibacterial test, biofilm observation and bacterial morphological examination. Electrochemical tests were used to investigate the corrosion property of Ti–Cu alloy. Furthermore, both Ti and Ti–Cu dental implants were manufactured and then implanted in the mandibular premolar sites of beagle dogs for 3 months with ligature-infected treatment. Implant-tissue samples were prepared for radiographic analysis, Micro-CT evaluation and histological examination.Results
Ti–Cu alloy was found to efficiently kill the attached bacteria by ways of damaging cell membranes and cell walls and strongly inhibit the biofilm formation. However, Ti–Cu alloy had excellent corrosion resistance similar with Ti. Further, Ti–Cu dental implants showed superior capacities of inhibiting the bone resorption caused by bacterial infection and enhancing bone formation.Significance
Ti–Cu alloy strongly inhibited biofilm formation in vitro and prevented bacterial infection associated with dental implant in vivo, making it great potential for application in dental implants with excellent antibacterial viability and positive effect against bone resorption induced by peri-implantitis. 相似文献14.

Purpose
To evaluate the effects of sex, skeletal age, sagittal skeletal pattern, and the interaction among these three factors on the pharyngeal airway widths and areas, and the positions and dimensions of surrounding structures.Materials and methods
Pretreatment lateral cephalometric radiographs of 418 growing orthodontic patients (183 males, 235 females); 6–20 years old (mean age, 13.95 ± 3.62 years), were collected from 2007–2014, Department of Radiology, Faculty of Dentistry, and divided into 3 skeletal ages according to cervical vertebral maturation stages, pre-pubertal (cervical stages (CS) 1,2), pubertal (CS 3,4), and post-pubertal (CS 5,6). Ten angular, 13 linear, and 3 cephalometric area measurements were analyzed. Three-way ANOVA and Factor analysis were applied to compare sex, skeletal age, and sagittal skeletal pattern differences in the pharyngeal airway dimensions and the surrounding structure dimensions and positions.Results
Sex–skeletal age interactions existed in the nasopharyngeal and oropharyngeal airway dimensions, and dimensions and positions (vertical, horizontal) of surrounding structures. Skeletal age–sagittal skeletal pattern interactions also affected the pharyngeal airway dimensions. In the post-pubertal period, male and skeletal Class III subjects tended to have larger pharyngeal airway, tongue, and soft palate dimensions; more anterior positions of the hyoid and tongue; and less obtuse soft palate angulation. The post-pubertal males also had more inferior positions of the hyoid and tongue.Conclusion
Interactions between sex–skeletal age and skeletal age–sagittal skeletal pattern affected the pharyngeal airway dimensions. The surrounding structure positions and dimensions varied according to sex–skeletal age interaction and sagittal skeletal difference. 相似文献16.

Biodentine? is a novel tricalcium silicate based material used both as a coronal dentine replacement and in pulp therapy. Its multiple use in sealing perforations, pulp capping and as a temporary restoration arises from its ability to promote dentine formation and to confer an excellent marginal seal. However, there is still room for improvement of this cement as it lacks the anticariogenic effect typically conferred by fluoride ion release as seen in glass ionomer cement based dental materials. Therefore, this study was conducted to investigate the impact of bioactive glass addition to Biodentine?.
Objective
was to compare the apatite formation capacity, specificity of the apatite type formed and fluoride ion release by Biodentine? cements that have been modified by three different compositions of bioactive glasses.Methods
High fluoride, high strontium and high fluoride plus strontium containing bioactive glasses were synthesized, incorporated into Biodentine? powder and four types of cements prepared. These cements were immersed in phosphate buffered saline solution and incubated for a period of 3 and 24 h, 3, 7 and 14 days. Fourier transform infra-red spectroscopy, X-ray diffraction, magic angle spinning nuclear magnetic resonance and fluoride ion release studies were performed.Results
Bioactive glass addition to Biodentine? led to pronounced formation of apatite. Where the bioactive glass contained fluoride, fluorapatite and fluoride ion release were demonstrated.Significance
Eliciting fluorapatite formation and fluoride ion release from Biodentine? is an important development as fluoride is known to have antibacterial and anticariogenic effects. 相似文献18.

Purpose
A single implant can be placed to retain an overdenture in the edentulous mandible. This study aimed at the development of Oral Health-related Quality of Life comparing immediate and delayed implant loading, i.e., loading after 3 months of submerged healing.Methods
In a randomized controlled trial, 158 participants received a single mandibular implant in the midline. Quality of life was measured using the summary score of the German 49-item Oral Health Impact Profile at baseline, one month after implant placement (direct loading group) as well as one and four months after loading.Results
Mean scores at baseline were comparable. Four months after implantation, a decrease of mean scores was recognized for both groups, indicating a significantly enhanced quality of life after treatment. When comparing the groups after both 1 and 4 months of loading, quality of life was insignificantly higher in the delayed loading group (1 month: 42.1 vs. 32.3; 4 months: 33.6 vs. 27.7). For immediate loading, an insignificant tendency to an earlier improvement was recognized (Δ1 month-baseline: 9.7, compared to Δ1 month-baseline: 6.4).Conclusions
The single mandibular implant concept was associated with a positive impact on quality of life. However, no statistically significant influence of implant loading on quality of life was found. 相似文献19.
Objective
The purpose of this study was to analyze the transverse dentoalveolar features of subjects with Class II Division 1 malocclusion in mixed dentition when compared to subjects with normal occlusion.Materials and methods
The study was performed on 192 randomly selected subjects in the early mixed dentition. According to sagittal skeletal and occlusal features the sample was divided into two groups: 88 subjects (53 females and 35 males) with Class II skeletal disharmony and Class II, division 1 malocclusion (Class II Group, mean age 8 years and 10 months ± 11 months) and 104 subjects (66 females e 38 males) with dentoskeletal Class I relationships (Class I Group, mean age 9 ± 1 years). The Class II group was further divided into two subgroups (maxillary protrusion group and mandibular retrusion group) on the basis of the skeletal characteristics. Intermolar and intercanine distances were measured on dental casts in both arches and posterior and anterior transversal discrepancy (PTID and ATID) were calculated.Results
Subjects with Class II malocclusion showed a significantly greater negative PTID (−2.1 mm) which was associated with a significantly reduced maxillary width with respect to the Class I group (−2.2 mm). The Class II group showed also a significantly greater negative ATID (−1.4 mm) when compared to the Class I group. Subjects with mandibular retrusion showed a significantly greater reduction both in the maxillary intercanine width (−1.7 mm). and in the maxillary intermolar width (−2.7 mm) with respect to the Class I group. Subjects with maxillary protrusion presented with a significantly greater constriction at the maxillary intermolar width (−1.7 mm) when compared to the Class I group.Conclusions
Class II malocclusion with mandibular retrusion is associated with a significant constriction of the maxillary arch with reduced intercanine and intermolar widths. When Class II malocclusion is due to a maxillary protrusion the constriction at the maxillary arch is limited to the intermolar width. 相似文献20.
