Abstract

The present study was undertaken to determine the biocompatibility of a newly-developed CaO-P2O5-MgO-SiO2-CaF system glass ceramic tooth implant. Two adult male monkeys were selected and 12 weeks after extraction of M1 and P1, 8 glass ceramic teeth were implanted into alveolar bone. At 1 week after implantation, 6 teeth were allowed occlusal function, and 2 teeth were left free from occlusion as control teeth. The implants were observed for 4-12 weeks and examined histopathologically. The results were as follows: 1. Seven implanted teeth were well maintained clinically, and only one tooth was lost after 5 weeks. 2. In histopathological observation, implanted teeth were surrounded by bone, and connected by bonyankylosis. At cervix of dental implant, connective tissue as also attached firmly to implanted tooth surfaces and epithelial attachment was observed. 3. Although these implants were allowed occlusal function at an early stage (1 week after implantation), osteogenesis around implants was not disturbed. These results suggest that the new glass ceramic implant has good biocompatibility and is useful as an implant tooth.

[CaO-P2O5-MgO-SiO2-CaF系统玻璃陶瓷牙种植体的临床及组织病理学观察]。

本文研究了新研制的CaO-P2O5-MgO-SiO2-CaF体系玻璃陶瓷牙种植体的生物相容性。选择2只成年雄性猕猴，在M1和P1拔除12周后，将8颗玻璃陶瓷牙植入牙槽骨。种植后1周，6颗牙恢复咬合功能，2颗牙作为对照牙不受咬合。观察植入物4 ~ 12周，进行组织病理学检查。实验结果如下:1.实验结果表明:7颗种植牙临床维持良好，5周后仅1颗牙脱落。2. 组织病理学观察，植牙被骨包围，骨关节连接。在种植体子宫颈处，结缔组织也牢固地附着于种植牙表面，并观察到上皮附着。3.虽然这些种植体在早期阶段(种植后1周)允许咬合功能，但种植体周围的成骨并未受到干扰。结果表明，新型玻璃陶瓷种植体具有良好的生物相容性，是一种实用的种植体。
