美学区种植同期引导骨再生采用不同愈合方式的评价研究(1)
[摘要]目的：美学区种植同期行引导骨再生(Guided Bone Regeneration，GBR)技术，探讨埋入式与穿龈式两种愈合方式对种植体周围组织的影响。方法：选择2011年6月-2015年6月上颌前牙种植体周骨缺损行GBR技术的种植修复患者42例，其中埋入式25例，穿龈式17例，测量两组种植义齿邻牙探诊出血(BOP)、牙周探诊深度( PPD) 、附着水平(CAL)与种植体边缘骨吸收量。结果：种植术后24个月，埋入式与穿龈式BOP阳性百分比为5.0% 与8.8%，PPD为(2.6±0.6)mm与 (2.4±0.6)mm，CAL为(2.6±0.9)mm与(2.6±1.0)mm，种植体边缘骨吸收量(0.51±0.65)mm与(0.58±0.67)mm，均无统计学差异。结论：在熟练掌握骨增量技术的前提下，埋入式与穿龈式两种愈合方式对种植体周围组织的影响无差异，几乎可以获得相同的临床效果。

Abstract： Objective To explore the influence of submerged and transmucosal healing on tissue around the implants in aesthetic zone with guided bone regeneration(GBR). Methods From June 2011 to June 2015，42 patients with bone defect in maxilla anterior region were followed up，25 patients received implans with submerged surgical technique and 17 with transmucosal surgical technique. The clinical parameters including bleeding on probing(BOP)，pocket probing depth(PPD)，clinical attachment level(CAL) at teech adjacent to implant and peri-implant marginal bone resorption after restoration were recorded. Results There was no statistically difference between the submerged and transmucosal group for BOP (BOP + sites： 5.0% vs. 8.8%)，PPD [(2.6±0.6)mm vs. (2.4±0.6)mm] and CAL [(2.6±0.9)mm vs (2.6±1.0)mm] at the 24 months follow-up visit. The differences of peri-implant marginal bone resorption were not significant，which was(0.51±0.65)mm in the submerged and (0.58±0.67)mm in the transmucosal. Conclusion The submerged and transmucosal healing can achieve similar outcome，when the implant is placed in aesthetic zone with GBR bone augmentation operation.

伴隨着种植技术的不断成熟，无论骨质量良好的种植位点，还是同期或分阶段进行组织增量的种植位点，获得长期稳定的骨结合已经成为现实。因此，目前种植体成功的概念不仅包括成功的获得长期稳定的骨结合，还必须包括稳定的美学效果。美学区临床上定义为微笑时暴露的牙及周围组织结构区域，基于这一定义，美学区包括所有暴露的位点，包括切牙和尖牙，甚至前磨牙。但是，在讨论美学种植时，通常以上颌前牙为例[1]。上颌前牙美学区由于自身生理解剖特点，临床中往往出现局限性骨缺损，因此是应用引导骨再生技术最频繁的位置。随着人们对于美学修复要求的提高，前牙区种植是目前关注的热点，然而国内外关于愈合方式对美学区的影响报道较少。本文就GBR技术中，埋入式与穿龈式两种愈合方式对种植体周围组织的影响进行评价分析，现报道如下。
