下顎位を改善し顔貌を回復した総義歯１症例

Abstract

This is a clinical case report of esthetic and masticatory impairment due to a mandibular protrusion during occlusion. The patient was a complete edentulous subject who complained about esthetic and matiscatory disturbance. First of all, treatment dentures were done, in order to improve the mandible position and recover the facial aspect. Objective evaluations were carried out to compare the improvements achieved after the insertion of the new dentures. The treatment dentures were used to improve patient's mandible position as well as vertical dimension. Once the facial appearance was recovered as a result of an appropriate mandible position, a reduction of the angle formed between the FH plane and the A-B plane from 87 to 83 was recognized after the insertion of the new dentures through the analysis of lateral cephalograms. It indicates that the mandible's position changed to backward position resulting in an improvement of the facial aspect. In the present clinical case report, not only subjective evaluation for appropriate mandible position and vertical dimension, but also including objective evaluation methods allowed us to evaluate and compare objectively the patient's pre and post operative condition.
