Studies in the Regeneration and Reattachment of Supporting Structures of the Teeth

Abstract

A considerable degree of soft tissue reattachment to the tooth and regeneration of alveolar process was attained following the surgical removal of a section of alveolar process and periodontal membrane exposing the root of the tooth. The reparative process was studied at intervals varying from 12 to 120 days. The difference between osteoblasts and cementoblasts in the reparative process appears to be one of position only. The factors concerned in the differentiation of these cells is discussed. The osteogenic effect of autogenous grafts of dentine and bone are compared. Evidence regarding the fate of bone grafts is presented. A theory of the mechanism of repair of bone when grafts are used is advanced.
