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 effect of three-dimensional prediction of aesthetics area after gingival-osteoplasty. Methods: Twenty-five patients undergoing periodontal hardware and software treatment were instrumented to perform preoperative alveolar bone location and fullness using a computed tomography (CT) technique to calculate the expected area of bone dressing and to create a surgical template for gingival dressing or crowns Prolonged operation and permanent crowns restored permanent porcelain crowns 6 weeks or 6 months after operation. The preoperative and postoperative 1, 12 months bacteria index (PI), modified sulcus bleeding index (mSBI), the expected bone height and Postoperative 1,12 months, the actual height of bone. Results: The PI and MSBI at 1 month and 12 months after operation in the 25 patients were significantly improved (P <0.05). The postoperative gingival health, gingival margin and prosthesis were stable. The expected bone height and postoperative 1 There was no difference in actual height at 12 months (P> 0.05). Conclusion: The accuracy of gingival - osteoplasty surgery can be improved by using dental CT and template technique, and better clinical efficacy can be obtained.
