“…(5) Most of the studies conducted on arch form are focused on finding a single shape in perfect conformity for the dental arch of a specific sample. (6) Despite individual differences, when the ethical variations are taken into consideration; the application of a single ideal arch form for every individual could affect the post treatment functional, esthetic and stable arch form outcomes (7). Among the various types of malocclusion found in human population Angle's class III malocclusion is one of the least common malocclusions seen in day to day practice.…”

Background: - Archforms play an important role in orthodontic diagnosis and treatment planning. Limitations for tooth movement, especially for incisor retraction arise from the basal bone where teeth are rooted. If teeth move excessively over the alveolar bone, periodontal complications and unstable treatment effects, even the tooth exfoliation may occur. The aim of this study is to compare the maxillary and mandibular arch forms of class I, class II, class III patients reporting for treatment in Saveetha dental college and hospitals, Chennai, Tamil nadu from June 2019 to January 2021.Materials and method: - It is a single centered retrospective study conducted in a private dental institution, Chennai. The data of patients reporting was collected from the dental hospital management system and the arch form was compared. Ethical clearance for this study was obtained from the Institutional review board. Statistical analysis was obtained using SPSS version 20.Results:-The results showed that there is no significant correlation in maxillary and mandibular arch forms among Angle’s Class I, Class II, and Class III malocclusion. Class I occlusal relationship was the most common class of malocclusion followed by Class II malocclusion. Ovoid arch was more common in class I, Class II, Class III malocclusion. Conclusion: - Within the study limits, it was concluded that Class I occlusal relationship was the most common class of malocclusion followed by Class II. Ovoid arch was more common in class I, Class II, Class III malocclusion followed by v-shaped and square arch forms in class I and class III and V-shaped arch was more prominent in class II patients.

Objectives: The most frequently encountered malocclusion in our daily clinical practice is Class II malocclusion with mandibular retrognathism. Treatment modalities for Class II malocclusion correction depend on numerous factors such as the severity of the malocclusion and the age at which the patient reports for the treatment. One of the innovations in Class II treatment is the PowerScope appliance. The objectives of this study were: (1) To evaluate dentoskeletal changes with the use of PowerScope appliance in the treatment of Class II division I malocclusion using lateral cephalograms in late adolescents. (2) To evaluate the soft-tissue changes with the use of PowerScope appliance in the treatment of Class II division I malocclusion using lateral cephalograms in late adolescents. Materials and Methods: This retrospective and cross-sectional study was done using pre- and post-treatment lateral cephalograms of 15 patients treated with PowerScope appliance who were under decelerated growth phase as assessed by cervical vertebrae maturation index (Stages 4, 5, and 6). All the lateral cephalograms were hand traced and measured by same investigator. Results: A highly statistically significant difference was observed between the pre-and post-angle formed by sella nasion plane and nasion to point B line (SNB), angle formed by nasion to point A line and nasion to point B line (ANB), condylion to point gnathion (Co–Gn), and distance between point A to nasion perpendicular (N perpendicular to Point A) to Pog skeletal parameters. It was found that a highly significant difference was noted for parameters upper molar to palatal plane (U6-PP), lower incisor to nasion to point B line (L1-NB), lower incisor to nasion to point B line (L1-NB*), lower incisor to mandibular plane angle (IMPA), and upper molar to pterygoid vertical line (U6-PTV). A significant difference was present for parameters upper incisor to nasion to point A line (U1-NA), while no difference was observed for upper incisor to sella nasion plane (U1-SN) and upper molar to pterygoid vertical line (U6-PTV). A significant statistical difference was observed between the pre-and post-lower lip to E line parameter. Conclusion: PowerScope caused significant skeletal changes by forward repositioning of the mandible as well as by an increase in the length of the mandible. There was significant retrusion of upper incisors and a highly significant increase in lower incisor protrusion, lower molar mesialization, and upper molar intrusion. Soft-tissue lower lip protrusion was significant.
