After 1 year of retention the occlusion was stable.

. The aim of this study was to compare the transverse dimensions of the dental arches and alveolar arches in the canine premolar and molar regions of Class II division 1 and Class II division 2 malocclusion groups with normal occlusion subjects. Class ii division 1 is when the maxillary anterior teeth are proclined and a. Class II Malocclusion Class II Malocclusion has two divisions to describe the position of the anterior teeth.

Class II occlusion is also known as. Class II Division 2 is where the maxillary anterior teeth are retroclined and a deep overbite exists.

Photocopies of the dental arches of 48 patients exhibiting Class II division 1 malocclusion with mandibular deficiency and of 51 individuals with normal occlusion were compared.

To achieve stability of the corrected malocclusion it is important to correct the inter-incisal angle and edge centroid relationship3. The power centric registration advocated by Roth was used to take centric relation bite registration for 50 patients 25 Class I and 25 Class II Division 1 and diagnostic models were mounted and analysed. Overjet and overbite as well.

Checklist for proper finishing of the occlusion. An open bite can exist even if the anterior incisors are touching edge to edge. To test the hypothesis that there is no difference between Class I CI normal occlusion Class II division 1 CIId1 and CII division 2 CIId2 and Class III CIII malocclusion with respect to arch widths width of the maxillary and mandibular arches gender dimorphism within groups and gender comparisons.

The panoramic wjd Class II Division 1 Malocclusion treated with the Andresen Appliance A B C Figs 1A to C. The treatment options for adults with increased overbite are limited to dentoalveolar changes that camouflage the condition.
