Orthodontics case study with skeletal class II division one malocclusion

Fig 1 pre-treatmentEmma Laing describes a case where she treated a skeletal class II division one malocclusion with a small retrusive mandible and chin.

Introduction

The majority of patients I see for treatment have malocclusions we can treat well within the realms of conventional orthodontics, whether with fixed appliances or aligners.

It is my pleasure to present a case of such nature that is near to completion.

Factfile

The university holidays would be an appropriate time for recovery from any surgery. The patient is medically fit and well and blind in his left eye.

Examination and clinical diagnosis

He presented with a skeletal class II division one malocclusion with a small retrusive mandible and chin. The vertical dimension and MMPA were increased. The nose deviated to the right. His soft tissue profile was obtuse and the nasio-labial angle was obtuse. The lips were incompetent with increased incisor display at rest and the tongue was forwards at rest and on speaking and on forming an anterior oral...
