Introduction and Aim: Various functional appliances are developed to remodel the glenoid fossa and, thereby change the position of the mandible and correct Class II malocclusion. Many diagnostic aids have already been used to evaluate the changes ,but Cone Beam computed tomography (CBCT), three -dimensional diagnostic tool is rarely used .So this study was conducted with an aim is to evaluate the changes seen in the temporomandibular joint (TMJ) after mandibular advancement in class II malocclusions with functional appliance therapy, using CBCT, and also to assess and compare the efficacy of Twin Block, Power Scope and Forsus Fatigue Device used for the correction of class II malocclusion.Materials and Methods: The retrospective study was performed using the 52 CBCT scans of 26 patients with class II malocclusion due to retrognathic mandible. The subjects were divided into three groups based on appliance (Twin Block, Power Scope and Forsus Fatigue Resistant Device) used for the treatment. The changes seen in TMJ after mandibular advancement and condylar response to functional therapy was evaluated using the six. Data obtained were subjected to one-way Anova analysis with Posthoc Tukey test. Software SPSS version 20 was used to analyse the data. The level of significance was set at p < 0.05.Results: In subjects treated with Twin Block, the condyle was displaced slightly downwards and anteriorly; and condylar height was reduced. The decrease in the anterior and superior joint spaces were also found. In subjects treated with PowerScope and Forsus Fatigue Resistant Device, there was an increase in condylar height and width with a decrease in anterior and superior joint space.Conclusion: All three appliances were found to bring about changes in TMJ structures, but amongst them the Twin block has proved to be more efficient.

Cephalometric Study

Background: Functional appliances such as Bionator have been used to treat Class II malocclusion. The purpose of this study was to compare the skeletal, dental and soft tissue effects of Bionator appliances with Multi-P (a newly developed appliance) in the treatment of Class II malocclusion. Subjects and methods: 45 class II children were chosen and randomly assigned to either the Bionator or Multi-P treatment group. After excluding 13 patients from the study, 21 patients in Bionator and 11 patients in Multi-P group have participated in the study. Lateral cephalograms were analyzed at the beginning (To) and at the end of treatment (T1) to evaluate the changes in both groups. The paired t.test and Leven’s test were enrolled for statistical analysis.Results: Reduction of ANB angle was detected in both treatment groups. The Bionator group underwent insignificant greater mandibular advancement as measured by the SNB angle. (p= 0.737) The mandibular plane angle increased insignificantly in both groups. (p> 0.05) The inclination of upper incisors decreased significantly in Multi-P group. (p= 0.042)Conclusion: Both appliances are effective therapeutic means for class II treatment associated with mandibular deficiency and may lead to normalization of the dentoskeletal parameters at the end of the treatment.

Objectives: The aim of this study was to compare the effects of two different functional appliances on skeletal, dental, and uvulo-glossopharyngeal dimensions. Materials and Methods: Pre- and post-treatment lateral cephalograms of 50 adolescent Class II patients with a retrognathic mandible were obtained from an archive and divided into two groups according to functional therapy. Twenty-five patients (14 females, 11 males, mean age: 13.5 ± 2.8) who were treated with Forsus Fatigue Resistant Device (FFRD) and 25 patients (17 females, eight males, mean age: 12.5 ± 0.4) who had received functional therapy through the twin block (TWB) were enrolled. Skeletal, dentoalveolar, tongue, uvula, hyoid position, and oropharyngeal airway parameters were measured using the Dolphin software, and uvulo-glossopharyngeal area measurements were performed with the AutoCAD software. Results: The TWB group exhibited remarkable mandibular advancement compared to the FFRD group (P < 0.05). Both of the treatments proclined mandibular incisors, and tongue dimensions increased significantly in both groups (P < 0.05). While the hyoid point moved forward and the oropharyngeal area increased significantly in the TWB group, no significant changes were observed in the FFRD group. The comparison of the TWB and FFRD groups with regard to uvulo-glossopharyngeal dimensions showed no significant differences between the groups (P > 0.05). Conclusion: Changes in uvulo-glossopharyngeal dimensions did not significantly vary between the two different functional therapies.
