Abstract
The purpose of this study was to investigate the morphological analysis of premature contact in the occlusal contact area on before and after the occlusal adjustment. Changes in the Occlusal Contact Area (OCA) and Luminosity Grade 1 (LG1°) of eleven patients with occlusal trauma were measured by use of an image analyzer system with IMAGE PC and personal computer before and after occlusal adjustment. These patients were selected as having no missing teeth, no prothodontic treatment, no TMJ dysfunction, and normal dental arch.
The results were as follows:
1. There was almost no difference in the total OCA of the left and right side befor and after occlusal adjustment in six patients, and in the individual, the OCA for the 1st. and 2 nd. molar also showed little difference.
2. Concerning the total LG1° of the left and right side of the dental arch, the values befor and after adjustment tended to be equal in eight patients, and especially in the 2 nd. molar showed a slight tendency of almost no difference on other teeth.
