“…Thus, the results obtained in this study for both reliability and stability were similar to versions in other languages and with samples of different sizes [24,25,26,27,28,41,42,43,44,45,46]. Although the sample size was small, it is understood that in the context of qualitative research, this may be small since the results are interpreted based on the context rather than quantitatively.…”

Objective: Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) is a useful index to assess aspects of oral malocclusion that impact individuals' oral health-related quality of life. This study aimed to validate the cross-cultural adaptation and equivalence of the PIDAQ questionnaire to the language of the Chilean adolescent population. Methods: We used the framework of the Guidelines for the Transcultural Adaptation Process of self-reports and the Manuals for a language inclusive for the transcultural adaptation of the PIDAQ. The instrument was tested on 32 Chilean adolescents with oral malocclusion between 11 and 17 years of age. We evaluated equivalence considering criterion, content, and construct validity according to COSMIN methodology and validated by Cronbach's alpha statistical test. A total of 23 items in the questionnaire were tested according to how clear and understandable the questions were to the reader and according to a Likert scale graduated in: not at all clear, unclear, unclear, clear, or very clear. For temporal stability, we calculated intraclass correlation coefficients (ICC). Results: We obtained an acceptable reliability with a Cronbach's Alpha of 0.951 for the total questionnaire. The questions grouped according to the dimensions of dental self-confidence, social impact, psychological impact, and esthetic concern obtained a Cronbach's Alpha of 0.955, 0.947, 0.946 and 0.939, respectively. The questionnaire showed high temporal stability at the test-retest with a total ICC of 0.907 (0.885-0.913). Conclusion: The cross-cultural adaptation of the PIDAQ questionnaire achieved equivalence with the original instrument and obtained reliable criterion, content, and construct validity in Chilean adolescents.

“…Alterations in the occlusal plane during the management of Class III problems often is a treatment objective. Such approaches include occlusal plane rotation during orthognathic surgery 15,16 as well as Class III camouflage treatment with the multiloop edgewise archwire technique. 17 In the current CM3 study, the occlusal plane rotated À4.08 in a counterclockwise direction during phase I.…”

Objectives To determine dentoalveolar and skeletal effects produced in mature patients by the Carriere Motion Class III (CM3) appliance followed by fixed appliances. Materials and Methods This retrospective study evaluated 32 patients at three time points: T1 (initial), T2 (removal of CM3), and T3 (posttreatment). Serial cephalograms were traced and digitized, and best-fit regional superimpositions were constructed. Eleven linear and 7 angular variables were measured. The starting forms of the CM3 patients were compared with a sample of untreated subjects with normal occlusions and well-balanced faces. Results The CM3 phase lasted 6.3 months, followed by a phase of fixed appliances lasting 12.9 months; the total duration of treatment was 19.2 months. Minimal skeletal changes were measured sagittally, with only a slight increase in lower anterior facial height observed during treatment. Most treatment changes were dentoalveolar in nature. Wits appraisal increased 4.0 mm during treatment. The molar relationship improved by 6.0 mm during phase I, a value that rebounded slightly during phase II, resulting in an improvement toward Class I of 4.8 mm. Best-fit regional superimpositions revealed anterior movement of upper molars relative to the maxilla and posterior movement of lower molars relative to the mandible. Conclusions The Carriere Motion Class III appliance is an effective and efficient method of resolving occlusal problems in minimally growing Class III patients. Primary treatment effects are dentoalveolar in nature with minimal skeletal alterations.

“…A consensus already exists in the literature which indicates that CCW rotation of the maxillary occlusal plane allowing for mandibular CCW rotation ensures the increase of chin projection and improvement of the soft tissue profile. 3,4,7,8 However, it is unlikely to assign the maximum and minimum thresholds that switch a positive balance to negative from the available evidence.…”

Purpose: To evaluate the effects of upper occlusal plane (UOP) inclination and incisor decompensations on the outcome of surgical Class II patients. Materials and Methods: Pretreatment (T0), preoperative (T1), and posttreatment (T2) cephalograms of 30 surgical Class II patients were included. Cephalometric measurements were performed using the Dolphin Imaging Software in this retrospective study. The differences between time points were analyzed with repeated measures ANOVA. Spearman correlation test was used to determine any correlations between either the UOP alterations or incisor decompensations and the cephalometric variables. Results: A significant improvement was obtained in the sagittal skeletal, dental variables, and soft tissue B point. Significant correlations were found between the decompensation achievement ratio and the change of the convexity angle. The relative percentage ratio (RPR) of the lower incisor was correlated with Wits appraisal, ANB, and Convexity Angle at the T2 stage. The RPR of the upper incisor was found to be correlated with lip strain. The relative surgical correction ratio of the UOP angle was found to be correlated with the surgical change of Wits appraisal and convexity angle. The RPR of the UOP angle was correlated with the SNB, ANB, and SN-GOGN angles at the T2 stage. Conclusions: Significant improvement in the incisor inclinations was achieved, but the incisors were inadequately decompensated at the preoperative phase. Surgical correction was limited by the inadequate presurgical decompensation. The surgical alteration of the UOP should be taken into consideration for the surgical planning to obtain better outcomes for Class II patients.
