摘要： 目的 评价改良牙槽嵴顶结缔组织转瓣技术在上颌前牙种植美学修复中的应用效果。 方法 选取20例上前牙单颗缺失种植复诊行二期手术且术前评估种植区唇侧软组织丰满度不足的患者作为实验组,二期手术同时行改良牙槽嵴顶结缔组织转瓣术,选取二期术前、术后2周、1个月、6个月及1年为观测时间点,记录唇侧软组织丰满度评分、唇侧软组织增量高度、牙间乳头相对高度、粉色美学指数。同时收集20例符合纳入标准但未行转瓣术病例作为对照组并记录以上数据。采用t检验、重复测量的方差分析等统计学方法对比分析数据。 结果 唇侧软组织丰满度评分及唇侧软组织丰满度测量结果显示,实验组术后各时间点软组织丰满度均较术前有增加(测量值T1-T0为0.3;T2-T0为0.27;T3-T0为0.26;T4-T0为0.26),且与对照组相比效果明显(P<0.001),短期及长期效果均良好;牙间乳头相对变化结果及PES评分显示实验组与对照组间无统计学差异(P>0.05)。 结论 种植二期使用改良牙槽嵴顶结缔组织转瓣技术,能有效增加唇侧软组织丰满度且稳定性良好,不会造成牙间乳头高度及PES评分的降低,适宜在种植修复软组织美学领域推广使用。

Abstract: Objective To evaluate the effect of an improved connective tissue flap technique applied in alveolar ridge crest for aesthetic implant restoration in maxillary anterior zone. Methods A total of 20 patients with flat or concave profile of labial soft tissue on implant site before second-stage surgery who received the improved connective tissue flap technique during second-stage surgery were enrolled as the experimental group; 20 patients according with the inclusive criteria who received second-stage surgery without the improved connective tissue flap technique were involved as the control group. We observed and measured the convex profile on the facial aspect, relative height of gingival papilla and pink esthetic score(PES)at the follow time points: before surgery; 2 weeks, 1 month, 6 months and 12 months after the second-stage surgery. The Data were analyzed with t-test and repeated measure. Results The convex profile was improved after second-stage surgery in the experimental group(T1-T0: 0.3; T2-T0: 0.27; T3-T0: 0.26; T4-T0: 0.26). There were significant difference between the two groups(P<0.001). Both long-term and short-term effects were satisfactory. There was no significant difference in the relative height of gingival papilla and PES between the two groups(P>0.05). Conclusion The improved connective tissue flap technique can be considered an effective method 山 东 大 学 学 报 (医 学 版)54卷6期 -孙睿男,等.改良牙槽嵴顶结缔组织转瓣技术在上颌前牙种植美学修复中的应用 \=-to augment the soft tissue during second-stage surgery without causing the shrinkage of gingival papilla or decrease of PES. It is worth wide application in soft tissue aesthetics of implant therapy.
