摘　　要：目的:观察三维预测美学区牙龈-骨成形术后临床疗效。方法:对25例需要进行牙周软硬组织处理的患者采用牙科CT分析术前的牙槽骨位置和丰满度,计算预期进行的骨修整区域,并制作手术模板,行牙龈修整术或牙冠延长术,临时冠修复6周或半年后行烤瓷冠永久修复,记录术前、术后1、12个月的菌班指数(PI)、改良龈沟出血指数(mSBI),骨预期高度和术后1、12个月骨实际高度。结果:25例患者术后1、12个月的PI、MSBI较术前明显改善(P<0.05);术后牙龈健康、龈缘协调,修复体稳定;18例患者骨预期高度和术后1、12个月骨实际高度无差异(P>0.05)。结论:通过牙科CT测量,结合模板技术,可以提高牙龈-骨成形术手术的精确性,获得更好的临床疗效。Objective： To observe the clinical effects of gingivoplasty or osteoplasty with special guidance after 3D prediction. Method： In 25 cases the need for periodontal tissue treated patients with dental CT analysis of preoperative alveolar bone height and thickness, analysis the expected gingival and bone position on the model, calculate the bone repair area to the expected, and make the operation template. Provisional crown were made after gingivoplasty or osteoplasty, and porcelain crown were made after six weeks or six months. The PI index （Plaque Index）,MSBI （modification sulcus bleeding index） and bone height were recorded before operation,postoperative 1, 12 month. Result：PI and MSBI were markedly improved in 25 patients after 1, 12 months （P 〈0.05） ;postoperative gingival health and gingival margin coordination were improved,prosthetic replacements were stable in all patients; bone actual height in 18 patients after osteoplasty 1,12 months were same as expected （P 〉0.05）. Conclusion：The clinical effects of gingivoplasty or osteoplasty with the dental CT measurement combined with the template technology was better.
