ABSTRACT
A case of hemifacial microsomia in an adult female is presented. The ascending ramus and condyle was primarily reconstructed using an iliac crest free bone graft. Following resorption of the bone graft, a custom-made total TMJ device (TMJ Concepts, USA) was used to correct the deformity. The alternative available reconstructive techniques are discussed and the advantages and disadvantages of the method selected.

In order to study the prevalence of mandibular dysfunction in orthodontically treated prognathic patients after retention, 60 randomly selected patients were examined clinically. The functional status of the patients was evaluated using the anamnestic, clinical dysfunction index, and the index for occlusal status introduced by Helkimo. Our patients showed a better functional status than the untreated prognathic patients, but one poorer than that of the general population. No difference, as demonstrated by indices, could be found between chin-cup and non chin-cup group, or between the conservatively treated and surgically treated prognathic patients without pre-orthodontic treatment.

The investigation presented here is concerned with the question whether the use of a chin cap by prognathic patients involves a functional risk to the masticatory system. By a comparison of two patient groups through use of the Helkimo Index no evidence for this could be found.
