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 effect of short-term clinical application of minimally invasive flap technique in oral implant surgery. Methods From January 2010 to December 2011, 25 patients (31 implants) who underwent non-flap surgery at the Stomatological Hospital Affiliated to China Medical University from January 2010 to December 2011 were selected as untreated patients and underwent classic flap surgery Twenty-five patients (40 implants) served as control group. Record and analyze the clinical data of the two groups on the day of surgery and referral, including the operation time, postoperative swelling and soreness, the shedding of the implant, the peri-implantitis and bone resorption, the height of the gums and so on. Results There was no implant in the untreated flap group and no implant was shed in the untreated flap group. The bone resorption level in the untreated flap group was lower than that in the control group (P <0.05), while the gingival papilla There was no significant difference in index between the two groups (P> 0.05). The operation time of untreated flap group was significantly shorter than that of control group (P <0.05). Conclusion Strict control of surgical indications under the premise of non-flaps surgery can greatly save the operation time, reduce postoperative response and obtain more satisfactory clinical results.
