Introduction: Dental arch width measurement is needed to determine diagnoses and orthodontic treatment planning of Angle Class II Division 1 and Class II Division 2  malocclusions that have narrow maxillary dental arch generally. Dental arch width in this study was measured by maxillary and mandibular intercanine width.  This study aimed to compare the differences of intercanine width between Angle Class II division 1 and Class II division 2 malocclusions. Methods: Descriptive comparative research with total samples of 67 study models, consisted of 34 Class II division 1 cases and 33 Class II division 2 cases. The minimum age of the samples chosen was 13 years old with no history of orthodontic treatment. A non probability consecutive sampling technique was used. Results: Study results showed the avarage maxillary and mandibular intercanine width of Class II Division 1 were 33,99 mm and 26,33 mm. Average maxillary and mandibular intercanine width of Class II Division 2 were 34,77 mm and 25,37 mm. Conclusions: T-test analysis showed no statistical significant differences in the intercanine width between Angle Class II Division 1 and Class II Division 2  malocclusions.

Abstract Introduction Several factors can interfere with orthodontic treatment, and it is important to verify which ones may hinder its success. Objective To compare the duration of orthodontic treatment between nasal and mouth breathers with Angle Class II, Division 1 malocclusion. Material and method This is an analytical observational study which used the records of orthodontic patients cared at a higher education institution in Sao Paulo state, Brazil, between 1999 and 2009. Data from the following variables were analyzed: age, gender, breathing mode (nasal or oral breathing), and treatment duration (beginning and end). Patients were matched for age and treatment used. The ANOVA test was applied to analyze the study data at 5% significance level (p<0.05). Result The study sample consisted of 36 individuals, 16 female (10 nasal breathers and six mouth breathers) and 20 males (eight nasal breathers and 12 mouth breathers), aged nine to 15 years (mean age=13.021). As for orthodontic treatment duration, individuals in the nasal breathing group remained between 27 and 74 months (mean duration=39.61) under treatment, whereas treatment of individuals in the mouth breathing group lasted between 29 and 50 months (mean duration=36.66). No statistically significant differences were observed between the study groups. Conclusions We conclude that the variable altered breathing mode does not interfere with treatment duration.

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.

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.

The present case report describes the orthodontic treatment of a patient with agenesis of maxillary left lateral incisor and Angle Class II, Division 1 malocclusion. The patient also presented with maxillary midline deviation and inclination of the occlusal plane in the anterior region. Treatment objectives were: correction of sagittal relationship between the maxilla and the mandible; correction of midline deviation, so as to cause maxillary and mandibular midlines to coincide; correction of overbite and leveling of the occlusal plane, so as to create ideal conditions for esthetic rehabilitation of anterior teeth. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as a requirement for the title of certified by the BBO.
