Abstract
A man aged 22 years had congenital partial anodontia. His dentition was as follows: Of these the deciduous teeth had to be removed because of caries and imminent exfoliation. His occlusion indicated prognathic position of the lower teeth, and the lower anterior teeth extended considerably above the gingival line of the upper anteriors. The cephalometric analysis revealed that the maxilla was retracted in relation to the cranium, while the mandible was protracted. In the functional analysis, the freeway space was 10.2mm, and at the physiological rest position the mandible swung downward and backward to approach the edge-to-edge bite. Initially, in order to correct the acute prognathic relation two kinds of bite planes were worn by the patient for a year and a half to increase the vertical dimension by 8mm. The permanent restorations were constructed at the established vertical position. The maxillary reconstruction was completed utilizing splinted full gold cast crowns on the molars, splinted bounded porcelain veneer crowns on the incisors and a removable partial denture replacing the absent teeth. The mandibular rehabilitation was accomplished utilizing splinted full gold cast crowns on the molars as well as a fixed partial denture that extended from the right second premolar to the left. After treatment, the anteroposterior relationship of the maxillary and mandibular teeth has been corrected, and with a concave face the position with respect to the cranium is not necessarily abnormal for the maxillomandibular base bone.
