[The periodontal changes following orthodontic tooth movement--a retrospective histological study in man. 2].
The maxilla of an orthodontically treated deceased (19 years, female) could be taken in autopsy. Pretherapeutically atrophied alveolar bone and a basally exdented maxillary sinus was found. The specimen was prepared histologically in the horizontal plane. The type of tooth movement could be reconstructed by analyzing the treatment documents.


RESULTS
Dependent on the tooth movement, a partial gain of osseous tissue in the atrophied alveolar region is possible by bone apposition in the subperiosteal layer. In the maxillary sinus region, however, bone resorption could be found in the subperiosteal layer in front of the tooth. The resultant apical perforation into the sinus could not be verified by radiographic examination.
