Seen from above the maxillary arch is narrower because it needs to adapt to a more anterior portion of the mandibular arch which is positioned posteriorly with regard to the upper teeth. Aetiology of Class II division 2 The majority of Class II division 2 malocclusions arise as a result of a number of interrelated skeletal and soft tissue factors. Upper incisors are labially inclined.

The success of treating Class II division 2 incisor relationship depends on the correction of the transverse anterior- posterior and vertical discrepancies. Upper incisors are tilted outwards creating significant. There is a large overbite.

115 normal occlusion subjects mean age 143 years and 50 complete Class II Division 2 subjects mean age 139 years. Class II malocclusion is considered the most frequent problem presenting in the orthodontic practice affecting 37 of school children in Europe and occurring in 33 of all orthodontic patients in the USA1 Class II malocclusion may also involve craniofacial discrepancies which can be adjusted when patients are adolescent. Clinical evidence has consistently shown the occlusal signs and muscular symptoms.

In this study we investigated tooth-wear patterns in adolescents with either normal occlusion or Class II Division 2 malocclusion. Class II division 2 - Dr Sylvain Chamberland Orthodontiste.

Interdental spaces can be seen on the maxillary arch.

There are contradictory views on the influence of characteristic dento-skeletal pattern on the harmony of a face profile.

This cephalometric X-ray shows a backward tipping of the upper incisors linguoversion or palatoversion that hides the posterior discrepancy of the lower jaw.

Angle and subsequent authors differentiated between Class II division 1 and 2 malocclusions based on the position of the incisors. This cephalometric X-ray shows a backward tipping of the upper incisors linguoversion or palatoversion that hides the posterior discrepancy of the lower jaw. Orthodontics prior to restoration was the key to minimizing biomechanical and functional risk.
