摘要
目的通过锥形束计算机断层扫描(cone beam computed tomography,CBCT)评价即刻种植术中从种植位点取自体骨植入种植体唇侧骨间隙的临床效果。方法选取需要行单颗前牙即刻种植的患者32人,共32颗患牙,按分层随机化分为试验组和对照组,每组各16颗。试验组拔牙后使用中空钻取种植位点处的自体骨,植入种植体后将自体骨碾碎植入到骨间隙中,放置愈合帽或即刻修复后缝合;对照组行常规即刻种植术,唇侧骨间隙植入Bio-Oss Collagen,放置愈合帽或即刻修复后缝合。所有患者术前和术后6个月复诊时拍摄CBCT,进行牙槽骨高度和宽度的影像学比较。结果两组种植体成功率均为100%。两组间术前和术后6个月牙槽嵴宽度和唇、腭侧骨板高度的变化,差异无统计学意义(P> 0. 05);组内手术前与术后6个月比较,两组牙槽嵴宽度和唇、腭侧骨板高度,差异均存在统计学意义(P <0. 05)。结论即刻种植术中从种植位点取自体骨植入种植体唇侧骨间隙的方法简单实用,可以获得良好的临床效果。
Objective To evaluate the clinical effect of filling the bone gap with autogenous bone gotten from immediate implant site by cone beam computed tomography( CBCT). Methods Total of 32 patients( 32 single anterior teeth that should be extracted) were divided into two groups with stratified randomization. Test group( 16 cases) : got the autogenous bone from extraction site with trephine and then implanted,filled the crushed autogenous bone into the gap around the implant,placed the healing cap or took immediate restoration and sutured the wound. Control group( 16 cases) : performed immediate implant after extraction,filled Bio-Oss Collagen into the gap,placed the healing cap or took immediate restoration and sutured the wound. CBCT should be taken after 6 months,compared the alveolar width and height with preoperative. Results The success rates of the two groups were 100%. Inter-group comparison between the two groups showed no significant difference in the change of alveolar width and height of labial and palatal bone plates before and 6 months after operation( P > 0. 05). Intra-group comparison in both groups showed significant difference in the alveolar width and height of labial and palatal bone plates before and 6 months after operation( P < 0. 05). Conclusion The method of filling the bone gap with crushed autogenous bone gotten from immediate implant site was simple and practical,which could obtain good clinical effect.
