目的：观察并评价微创不翻瓣技术在口腔种植手术中的短期临床应用效果。方法选择2010年1月至2011年12月于中国医科大学附属口腔医院种植中心接受不翻瓣种植手术的患者25例（31枚种植体）作为未翻瓣组，同期接受经典翻瓣种植手术的患者25例（40枚种植体）作为对照组。记录并分析两组病例在手术当天及复诊时的相关临床资料，包括手术时间、术后肿痛不适时间、种植体脱落情况、种植体周围炎与骨吸收水平、牙龈乳头高度等。结果未翻瓣组中有1枚种植体脱落，对照组中无种植体脱落；未翻瓣组病例术后1年的骨吸收水平低于对照组（P<0.05），而两组的牙龈乳头指数差异并无统计学意义（P>0.05）；未翻瓣组的手术时间、患者术后肿痛不适时间明显少于对照组（P<0.05）。结论在严格控制手术适应证的前提下，不翻瓣手术可大大节省手术时间，减轻患者术后反应，获得更为满意的临床效果。

Objective To observe and evaluate the clinical effects of minimally invasive flapless technique in dental im-plant surgery. Methods Totally 25 patients(31 implants)who received flapless surgery during the period between Jan-uary 2010 and December 2011 at the Implant Center of Stomatology Hospital of China Medical University were selected as the flapless group and another 25 patients(40 implants)who received traditional surgery during the corresponding pe-riod were selected as the control group. Related clinical data were recorded and analyzed on the day of surgery and fol-low-up,including length of surgery,duration of discomfort after operation,loss of implant,peri-implantitis and level of bone resorption,gingival papilla height,etc. Results One implant was lost in the flapless group,while no implant failed in the control group. Less bone resorption was observed in the flapless group(P < 0.05),while gingival papilla index showed no significant difference between the two groups(P>0.05). The length of surgery and duration of discomfort af-ter operation in the flapless group were significantly less than the control group(P<0.05). Conclusion On the basis of strict control of operation indication,flapless surgery will save operation time to a large extent,relieve patients postopera-tive reaction and obtain more satisfactory clinical results.
