The soft-tissue profile preferences of a group of lay persons and professionals.Suliman, Shameela Haroon. January 2008 (has links)
<p>" / Although facial aesthetics has always been a part of orthodontic diagnosis and treatment planning, the criteria for facial evaluation have been somewhat arbitrary. They are often based on parameters from the field of art or from evaluating faces chosen by orthodontists or other professionals. The aims and objectives of the study were to determine the soft-tissue profile preference of a group of lay persons and professionals / to compare the preferences of the male and female assessors (lay persons group) with regard to the preferred profiles for the maleand female patient respectively / to test similarities and differences in the professional's perceptions of the various profiles. This qualitative study was undertaken at the orthodontic clinic at UWC using post-treatment soft tissue profile photographs of patients who had attended the orthodontic clinic..." / </p>

Changes in arch dimentions atfer extraction and non-extraction orthodontic treatment.Mac Kriel, Earl Ari. January 2008 (has links)
<p>The Aim of this study was to determine wheteher there are changes in the interdental arch widths and arch lengths of the madibular and maxillary arches during no-extraction and extraction orthodontic treatment. The records of 78 patients treated by one orthodontist were used for this study. Statistical data analysis included descriptive statistics of the data, analysis of the matrices, Wilcoxon Signed Rank tests and Kruskal-Wallis tests of the changes which occured during treatment. The study concluded that extraction treatment does not necessarily lead to the narrowing of the dental arches in the canine region.</p>

Cephalometric evaluation of soft tissue effects induced by a class II corrector in different facial patternsWard, Robert 06 July 2015 (has links)
Objective: To determine the magnitude of soft tissue changes in subjects with different facial patterns following Class II correction.
Materials/Methods: A retrospective sample of 80 subjects exhibiting Class II malocclusions was used. Subjects were categorized into facial types according to pre-treatment values of MPA and Y-axis, which yielded 20 brachycephalic, 40 mesocephalic, and 20 dolichocephalic subjects. Data collection included digital analysis on the pre-treatment (T0) and post-treatment (T1) cephalometric radiographs. A paired t-test statistic was used to investigate the differences between the three facial groups at T0 and T1.
Conclusions: There are differences in the soft tissue effects observed in patients treated with the XbowTM appliance which are related to the pre-existing facial pattern (p<0.05): The mesocephalic group showed increased retrusion of the upper lip to E-Plane compared with brachycephalic, and dolichocephalic groups. The dolichocephalic group showed significantly more flattening of the mentolabial fold compared to the mesocephalic group.
