Infective shortening of the mandible can occur in some cases, due to changes in the condylar regions of the mandible (Fig. 7.35). In some instances, this will be identified as being due to idiopathic condylar resorption. This condition is fortunately rare, but can result in unfavorable downwards and backwards movement of 'IV point in response to changes in the condylar region. It is predominantly seen in female patients16 (Fig. 7.36).
