将24只新生仓鼠的上颌磨牙移植到股骨上28天，其中7只显示出牙冠和牙根的生长和发育。牙釉质、牙本质、牙髓、牙骨质、牙周膜和牙槽骨在正常位置发育，就像以前移植到皮下结缔组织中的磨牙一样。观察到在异物环境中和牙根诱导影响下发育的牙槽骨本身与股骨之间的几种关系。股骨与牙掌骨相连，共同支撑牙槽。在移植磨牙根附近的一些区域，股骨被建立起来以连接和支撑牙槽骨。在其他区域，由于臼齿根的发育或臼齿根偏离其正常发育方向，股骨被吸收。尽管努力定向移植的磨牙萌出，但方向发生了改变，没有观察到牙齿萌出的证据。
Seven of 24 newborn hamsters developing maxillary molars which were transplanted to the femur for 28 days showed growth and development of crowns and roots. Enamel, dentin, pulp, cementum, periodontal ligament and alveolar bone proper developed in their normal locations just as they had done previously in molars transplanted into subcutaneous connective tissues. Several relationships were observed between alveolar bone proper, developed in the foreign body environment and under the inductive influence of the tooth root, and femoral bone. Femoral bone was continuous with alvolar bone and supported the tooth socket. In some areas near transplanted molar roots, femoral bone was built out to join and support alveolar bone. In other areas, femoral bone was resorbed by the development of a molar root or the molar root was diverted from its normal direction of development. Despite the effort to orient transplanted molars for eruption, the orientation was altered and no evidence for tooth eruption was observed.
