OBJECTIVE: This study aims to determine the mean collum angle of maxillary central incisor and to compare it between high angle and low angle patients undergoing orthodontic treatment. METHODOLOGY: This cross-sectional, observational study was conducted using lateral cephalometric radiographs of 61 class II division 1 patients (comprised 32 males, 29 females, age range 13 to 30 years) from the record files of patients inducted for Orthodontic management from June 2020 till August 2020 at the Department of Orthodontics, Sindh Institute of Oral Health Science, Jinnah Sindh Medical University, Karachi, Pakistan. The sample was divided on the basis of Vertical Analysis (angulation of mandibular plane) into high and low angle cases. Collum angle was measured using the angulation of the Maxillary Central Incisor (MCI). Student t-test was used to compare the mean difference of the collum angle between skeletal vertical malocclusions. RESULTS: Mean value of the collum angle for high angle (Vertical Growth pattern) cases were mean ± standard deviation (4.35°±1.49°) while for low angle groups (Horizontal Growth pattern) were (2.41°±1.60°). CONCLUSION: There Collum angle of permanent maxillary central incisors differ significantly (p<0.001) among high angle and Low angle malocclusions cases (n=61) and showed pronounced axial bending in Class II division 1 incisors with high angle (4.35° ± 1.49°) as compared to low angle malocclusion (2.41° ± 1.60°). KEYWORDS: Collum Angle, Maxillary Central Incisor, Orthodontic Treatment, High Angle, Low Angle.

Basic descriptive cephalometric data are presented for 30 individuals with untreated Class II Division 1 malocclusions, 15 males and 15 females. Two radiographs of each subject were examined, the mean age for the first being 12 years one month, and for the second 17 years five months, thus spanning the period during which orthodontic treatment is usually carried out. Mean values for 38 bony and dentoalveolar parameters were calculated, and the male and female groups were compared. There was a tendency on average to a mild skeletal II pattern, with mild mandibular retrognathism. The mean increase in many of the linear measurements in the males was up to three times that seen in the females, and the females had a more downwards and backwards pattern of mandibular growth rotation than the males.

Dental ankylosis may be a significant complication in orthodontic clinical practice. This case report describes the management of a malocclusion, complicated by an ankylosed maxillary central incisor, which arose during orthodontic treatment, following an acute traumatic injury. The use of the ankylosed incisor in successfully managing the significant Class II division 1 malocclusion is described.

The aim of orthodontics treatment is normalization of teeth position in three planes, using various orthodontics appliance to reach the chepalometric standar and normal occlusion. Orthodontic treatment for dentoskeletal class II division 1 malocclusion in growing patients using myofunctional appliance may correct anteroposterior planes of mandibula. This study was a descriptive retrospective analytic study to look at the success of Orthodontic treatment for dentoskeletal class II division 1 in growing patients with myofunctional appliance using chepalometrics analysis Steiner value. The sample used in this study is chepalogram radiographic from patient with dentoskeletal class II division 1 malocclusion in growing patients before and after using myofunctional appliance in PPDGS orthodontics Clinic of Padjadjaran University. Statistic analysis were performed with pair t-test and Wilcoxon. Based on this study, it is concluded that orthodontic treatment with myofunctional appliance such as activator and twin block in growing patient with dentoskeletal class II division 1 malocclusion shows significant changes and compatibility with the normal criteria.

Introduction. Orthodontic treatment of Class II Division 1 (II/1) malocclusions in adults can be challenging since skeletal effects are limited. Possible treatment options are orthodontic camouflage or orthognatic surgery, in severe cases. The aim of this paper was to present a successful management of Class II malocclusion in an adult patient using temporary anchorage devices (TADs). Case report. After detailed clinical examination, study models and cephalometric analysis, a 26 years old patient was diagnosed with Class II malocclusion, an overjet of 12 mm, congenitally missing tooth 41 and midline shifted to the right in upper dental arch. In prior orthodontic treatment, patient had upper premolars extracted. Posterior teeth in upper left quadrant were shifted mesially. The camouflage treatment was considered, using temporary anchorage devices (TADs) to distalize posterior teeth on the left side, and gain space for incisor retraction and midline correction in upper dental arch. Results. Using TADs as additional anchorage in anterior region and coil spring for molar distalization, the space was made for tooth 23, midline correction and incisor retraction. After 40 months, a satisfactory result was achieved, overjet and midline correction, class I canines occlusion and class II molar occlusion. Conclusion. Class II/1 malocclusion in adults can be successfully treated using TADs. The success depends on the severity of malocclusion and patient cooperation.
