兔下颌骨前牙区剩余牙槽嵴模型的建立
Establishment of a rabbit model of anterior residual alveolar ridge
摘要
Abstract
BACKGROUND: A proper anterior residual alveolar ridge model can provide basis for the preservation and repair of residual alveolar ridge.OBJECTIVE: to establish a rabbit animal model of anterior residual alveolar ridge.METHODS: The eighteen New Zealand white rabbits were selected, both side of central incisors of 18 rabbits were extracted under the general anesthesia to prepare anterior residual alveolar ridge models. Rabbits were killed at 4, 8, and 12 weeks after operation. The length, width and height of residual alveolar after extraction were measured by Vernier caliper. The healing process of teeth extraction was observed by hematoxylin-eosin staining. The remodeling of bone trabecula in after extraction was examined by X-ray.RESULTS AND CONCLUSION: The length, width and height of residual alveolar ridge were gradually decreased with time prolonged. Osteoblasts could be seen scattered in teeth extraction, new trabecular bone and vascular network was born. The deposition of new bone was continued in teeth extraction, the boundaries between new bone and the alveolar bone was not clear, and new bone and bone remodeling were happening in teeth extraction.
