骨缺损的修复是一个棘手问题。对牙槽嵴因失牙而产生的齿槽吸收,为了恢复其生理功能和外形,过去曾采用多种方法。由于自身骨组织存在来源问题,异体组织有排异问题;合成材料的理化性质等多种原因,使其发展受到一定限制。本文介绍了用颗粒型羟基磷灰石在4种不同病种中的应用。①拨牙后牙槽窝内立即填塞30例,②铁芯羟基磷灰石人工种植牙根立即法为固位而填塞13例,③牙周病骨缺损填塞5例,④外伤后骨缺损填塞2例。通过临床表现,术后X线片1周、1月、3月、6月的观察,证实颗粒型羟基磷灰石种植材料与牙和骨的理化性能相似,具有良好的生物相容性,能诱导新骨生长,是一种优良的种植材料。作牙槽窝内填塞成功率高,能有效的保存牙槽嵴的高度 宽度和外形,有利于义齿的支持和固位。
Repair of bone defects is a thorny problem. Alveolar ridges of the alveolar ridge due to tooth absorption, in order to restore their physiological function and appearance, the past has used a variety of methods. Because of its own source of bone tissue problems, allograft rejection problems; the physical and chemical properties of synthetic materials and other reasons, its development is subject to certain restrictions. This article describes the use of particulate hydroxyapatite in four different disease types. ① Immediately after the tooth was sutured in the socket 30 cases, ② iron hydroxyapatite artificial root implants immediate method for the retention and filling in 13 cases, ③ periodontal disease bone defects in 5 cases, ④ traumatic bone defect filling 2 example. Through the clinical manifestations, postoperative radiographs of 1 week, January, March, June observation, confirmed that particulate hydroxyapatite implants and teeth and bone physical and chemical properties similar to, has good biocompatibility, can Induction of new bone growth, is an excellent planting material. For the success rate of alveolar fossa filling, alveolar ridge can effectively save the height width and shape, is conducive to the support and retention of the denture.
