Abstract
The following study was undertaken to investigate the effect of the increase in the occlural vertical dimension on the facial height, the periodontium of the teeth and the temporomandibular joint in the adult rat. Twenty adult rats were included in the study. Fourteen rats were used as experimental animals, while the rest six animals were control. Each experimental animal received an acrylic appliance fabricated and applied to the maxilla. The appliance covered the maxillary molars and raised the occlusion by an amount varied from one animal to another. This amount ranged from 0.55mm. to 3.10mm. In order to measure the vertical dimension and detect its change, two little holes were drilled, the first in the buccal aspect of the maxillary bone and the second in the buccal aspect of the mandibular bone. These two holes were filled later by amalgam alloys. The vertical dimension was measured before and after the insertion of the appliance as well as at the end of the experiment. [TRUNCATED]
