牙周病所引起的牙周骨组织吸收是导致牙齿松动脱落的主要原因之一。如何防止牙齿松动脱落和修复牙周骨缺损乃是多年来口腔领域研究的重要课题。单纯行根管内钛钉植入虽可减少牙齿松动度,但不能解决骨缺损的修复问题。近年来国内外采用生物活性玻璃陶瓷材料(biological activated glass ceramic,BGC)修复骨缺损。但由于其修复骨缺损的时间较长,在修复期间内要靠外固定方法来解决牙松动问题。外固定方法并不十分理想,且
Periodontal disease caused by periodontal bone tissue absorption is one of the main reasons leading to loose teeth. How to prevent the teeth from loosening and repairing the periodontal bone defect is an important topic in oral research for many years. Simple root canal nail implants can reduce the tooth mobility, but can not solve the problem of repair of bone defects. In recent years, biological activated glass ceramic (BGC) has been used to repair bone defects at home and abroad. However, due to its long time to repair bone defects, external repair methods to solve the problem of loose teeth during the repair. External fixation method is not very good, and
