Background: Facial asymmetries are common in patients with skeletal class III malocclusion and posterior crossbite. Maxillary expansion and protraction (ME & P) and then fixed orthodontic treatment may affect positively on these asymmetries. Objectives: We aimed to investigate the effects of applying ME & P by the rapid maxillary expansion (RME) and face mask and then fixed orthodontic treatment on soft tissue asymmetries in adolescent patients with skeletal class III malocclusion and posterior crossbite. For this purpose, the 3D facial imaging system of stereophotogrammetric (3dMD) recordings was analyzed quantitatively in the pre-treatment (T0), ME & P (T1), and post-fixed orthodontic treatment periods (T2). Materials and methods:The study included 28 (11 females, 17 males) individuals with skeletal class III malocclusion and posterior cross-bite (5 patients with bilateral and 23 patients with unilateral cross-bite) and soft tissue facial convexity angle of 175.11 o ± 1.06 o with a mean age of 9.37 ± 0.54 years. Three-dimensional photographs were taken from the individuals before the ME & P (T0), 6 months after the ME & P procedure and before starting fixed orthodontic treatment (T1), and after removing all orthodontic appliances from the mouth at the end of the fixed orthodontic treatment (T2). 3dMD Vultus software was used to evaluate the data of 34 linear and 16 volumetric as a total of 50 measurements in soft tissue analysis. Results: The right-left volume differences, the Root Mean Square (RMS) values, and linear width measurements in the upper, mid, and lower face regions when evaluated at the T1-T0, T2-T1, and T2-T0 period intervals, were found to a decrease in these values and improvement of asymmetry. Conclusion:The asymmetry in the soft tissue in all face regions was corrected with ME & P and fixed orthodontic treatment. The most obvious asymmetry improvement occurs in the lower face area. It should be taken into consideration that asymmetry will improve with RME and face mask application and fixed orthodontic treatment in adolescents with Class III malocclusion and posterior cross-bite and treatment planning should be done according to that.
Background: Functional and camouflage orthodontic treatments in cl II malocclusions are different treatment methods that are usually used in orthodontic practice. A comparison of treatment success between those treatment groups shows which treatment method is better to choose.Objectives: This study aimed to compare functional and camouflage orthodontic treatments outcome in patients with class II malocclusion. Materials and methods: The sample size was from individuals who completed treatments
Background: Functional and camouflage orthodontic treatments in cl II malocclusions are different treatment methods that are usually used in orthodontic practice. A comparison of patients' satisfaction with these two treatment groups is an important tool for the evaluation of treatment outcomes. Objectives: We aimed to compare patients' satisfaction with orthodontic treatment subjectively (according to the opinion of patients) between functional and camouflage orthodontic treatments in patients with class II malocclusion. Materials and methods: The sample of the study was formed from individuals whose treatments were finished between February 2017 and July 2020 at the Department of Orthodontics, Faculty of Dentistry at Suleyman Demirel University, Turkey. A satisfaction questionnaire was used to evaluate the satisfaction of the patients with the treatment process at the end of their treatment. The subjects of the study were selected from 2 genders and a total of 146 cases of average age 11-22 years. The research material consists of a satisfaction questionnaire that was given at the time of treatment end. Results: The general satisfaction questionnaire score was found to be higher in the patients who received functional orthodontic treatment (P-value = 0.011). In the subgroups, the total questionnaire scores among the treatment subgroups were found to be quite similar. Conclusion: In our study, the satisfaction level of the quality of life questionnaire was found to be high, while in response to more specific questions on satisfaction, some departments of the questionnaire found less satisfaction or dissatisfaction in patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
