Abstract

This is the second article in a series on conundrums in orthodontics. A Class I molar relationship is a frequent aim of orthodontic treatment. There are, however, examples where intentionally finishing to a Class III molar relationship is the more pragmatic and preferable option. Pursuing this approach in the appropriate circumstances may, for example, prevent deleterious consequences to the facial profile or avoid the need for further dental extractions. This article explores the indications for finishing cases to a Class III molar relationship with illustrated clinical cases.

CPD/Clinical Relevance: Dogmatic attempts to deliver Class I molar relationships, in all cases, without consideration of the consequences, have the potential to cause the patient harm. The orthodontist must then consider all possible options available, including those resulting in a Class III molar relationship.

Article

In this second paper on conundrums in orthodontics, we explore the uncommon approach of finishing treatment to a Class III molar relationship. A Class I molar relationship is often a key aim of treatment, but there are instances where dogmatic attempts to deliver this may beunwise because they have the potential to cause harm. Orthodontic treatment may intentionally culminate ina molar relationship that is either a full unit Class II or Class III.1,2 There are severalreasons why this may be the preferred option, and frequently, it is theresult of pragmatic treatment planning. While finishing to a Class II molar relationship is relatively common, this is not true for Class III molarrelationships. The latter is the focus of this article and here we will consider the indications for finishing cases to Class III molar relationship and illustrate these with clinical cases.
