Occlusion

Course Outline

What is Occlusion?

The aim of this series of papers is to explore the role of occlusion in dental practice. The range of opinion in the dental profession as to the importance of occlusion is enormous.1 It is very important that the profession in general and practising dentists in particular have a balanced view of occlusion. This is more important than every patient having a balanced occlusion. The fact that the study of occlusion is characterised by extremes makes it confusing and possibly difficult for individual dentists to find a philosophy which is in line with contemporary good practice supported by evidence from practice-based research.

The Examination and Recording of the Occlusion: why and howBefore presenting ‘how’ the examination and recording of the occlusion may be achieved, some attempt should be made to justify ‘why’ it is necessary. It may appear to be a strange way of justifying the need to examine the patient’s occlusion, but this will initially involve a study of the influences of mandibular movements.
