摘要
目的:通过对牙种植接受引导骨再生术(GBR)的患者在术后不同时期进行牙CT扫描,测量所植入的Bio-Oss的体积变化,从而计算出Bio-Oss在人体内的剩余量。方法:选取9例牙种植Ⅰ期手术同期完成引导骨再生术的患者,在术后1周、3个月、6个月分别进行种植区牙CT扫描,通过测量、计算得到Bio-Oss在植入人体后不同时期的体积变化,从而得出其在术后3个月、6个月的剩余量。结果:通过测量、计算,得出Bio-Oss在术后3个月的剩余量为32.72%±18.35%,术后6个月的剩余量为15.75%±16.73%。结论:牙种植引导骨再生术植入Bio-Oss的吸收量随时间增加而增加。应用牙CT扫描测量Bio-Oss的吸收情况是可行的方法。
PURPOSE： To measure the absorbed quantity of Bio-Oss by using dental CT scanning and measuring the variety of the volume of Bio-Oss. METHODS： Nine patients were preformed stage I surgery of dental implants and guided bone regeneration-membrane technique （GBR） simultaneously. These patients were scanned by dental CT at the end of 1- week, 3-month and 6-month after operation, respectively. The measurements of the varied volume of Bio-Oss with dental CT scanning were conducted . Finally the remaining quantity of Bio-Oss in the patients＇ jaw bone was obtained. RESULTS： The results suggested that the remaining quantity of Bio-Oss was 32.72%＋15.35% at the end of 3- month post operatively and 15.75%-＋16.73% at the end of 6-month postoperatively. CONCLUSIONS： It is concluded that there is a decrease in the remaining quantity of Bio-Oss in GBR along with the increase of time. As a kind of osteoconductive material, Bio-Oss can be absorbed and replaced by newly formed bone. Using dental CT scanning to measure the volume of Bio-Oss in man is predictable.
