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.

The results of an analysis of treatment and post-treatment changes in 48 unselected Class II Division 1 malocclusions are presented. All the cases were at least 1 year out of retention (mean 34·7 months). Mean values have been given for several features. In particular, the mean overjet reduction during treatment was 7·0 mm, the mean relapse 1·1 mm and the mean net overjet reduction 5·9 mm. The relationship of “final” overjet to overbite, overjet, skeletal pattern and lower lip height at different stages of treatment is described. There is wide variation in “final” overjet in relation to any of the single factors investigated but five significant correlations were found.

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.

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.

The orthodontic treatment of severe class II division 1 malocclusions is often difficult, which leads some specialists to offer a surgical correction of the overjet. Treatment is made complex by the value of the horizontal overlap as much as the « depth » of deep bite that is very often present alongside the malocclusion. This is why we are offering a treatment protocol including a FABP (Fixed Anterior Bite Plate) which will allow, if the patient cooperates, to correct the anatomic anomaly while concurrently establishing new masticatory cycles in order to stabilize and preserve the results obtained. It is this systemic approach of treatment that is the focus of this article.

A group of 30 general dental practitioners were asked to plan treatment for a series of 10 Class II division 1 malocclusions of graded severity. The results were assessed against a gold standard provided by three consultants. Only 14 per cent of practitioner treatment plans agreed with the gold standard and agreement was worst for those cases requiring the use of headgear. When consultants and General Dental Practitioners (GDPs) were asked whether a case should be referred for advice before the GDP began treatment, 64 per cent of GDP decisions agreed with those of the consultants. On 13 per cent of occasions, however, the GDP would have initiated incorrect treatment without seeking consultant advice.

INTRODUCTION: This article demonstrates the description and use of a new appliance for Class II correction. MATERIAL AND METHODS: A case report of a 10-year 5 month-old girl who presented with a skeletally-based Class II division 1 malocclusion (ANB = 6.5º) on a slightly low-angle pattern, with ML-NSL angle of 30º and ML-NL angle of 22.5º. Overjet was increased (7 mm) and associated with a deep bite. RESULTS: Overjet and overbite reduction was undertaken with the new appliance, Fixed Lingual Mandibular Growth Modificator (FLMGM). CONCLUSION: FLMGM may be effective in stimulating the growth of the mandible and correcting skeletal Class II malocclusions. Clinicians can benefit from the unique clinical advantages that FLMGM provides, such as easy handling and full integration with bracketed appliance at any phase.

Objectives: To determine and analyze the maxillary incisal jaw bone thickness among different vertical skeletal facial types of Class II Division 1 malocclusion. Materials and method: The samples (n=121) between 12-14 yrs of age were divided into three groups (low angle, average angle, high angle) based on their SN-MP angle. Linear measurements were processed and analyzed statistically. The characteristics of abnormal incisor jaw bone thickness at upper and lower incisors among three vertical facial skeletal types were studied in detail. Results: At the upper and lower central incisors low angle individuals presented greater dentoalveolar, basal bone thickness than high and average angle individuals. The distance from the root apex of upper and lower central incisors were far away from the lingual cortex in low angle than high angle individuals. Conclusion: Among different vertical facial types with Class II Division 1 malocclusion in early permanent dentition may accord to establish discriminate values as a sample to set up the cephalometric standard for the appropriate diagnosis to provide better treatment plan for the clinicians.
