摘要:

文题释义:
引导骨组织再生术:将生物膜作为一屏障将软组织与骨组织(植骨材料)隔开,防止上皮细胞和结缔组织来源的成纤维细胞向骨缺损区生长,给迁移速度较慢的成骨细胞提供生长的空间,是骨缺损后最常用的一种手术方法。
改良翻瓣术的优点:能显著提高引导骨组织再生修复后的颈部轮廓,且研究的临床方法简单,无需额外的生物材料,不会产生骨作用及不良反应,在骨缺损较小的前牙种植病例的治疗中是一种较好的选择。

背景:有研究表明常规翻瓣引导骨组织再生术是上前牙即刻种植中应用较多的方法,在骨缺损较小时是一种较理想的方法,但该术式在颈部难以获得较好的成骨效果。
目的:评价上前牙改良翻瓣即刻种植的临床应用效果。
方法:临床选择上颌前牙即刻种植患者60例随机分为2组,改良翻瓣组30例采用旋入适合高度及直径的愈合基台后行埋入式愈合,常规翻瓣组30例采用旋入覆盖螺丝后行埋入式愈合,术后6个月制取数字化印模行全瓷冠修复。随访2年,比较两组种植体存留率、红色美学指数评分、牙龈增长值和种植体唇侧骨吸收的变化。
结果与结论:①两组种植体存留率均为100%;②与常规翻瓣组比较,改良翻瓣组红色美学指数评分及牙龈缘增长显著升高(P < 0.05),唇侧骨厚度显著降低(P < 0.05);③改良翻瓣组种植体周围牙龈近远中增长值略高于常规翻瓣组,但差异无显著性意义(P > 0.05);④结果证实,改良翻瓣即刻种植有利于上颌前牙区的软硬组织重建效果。

Abstract: BACKGROUND: Studies have shown that conventional flap-guided bone tissue regeneration is a method commonly used  in the immediate implantation of the upper anterior teeth. It is an ideal method for repairing small bone defects, but it is difficult to achieve favorable osteogenesis effect in the tooth neck area.
OBJECTIVE: To evaluate the clinical effects of modified flap immediate implant in maxillary aesthetic area. 
METHODS: Sixty cases of immediate implant placement were investigated, and randomized into two groups: 30 received modified flap immediate implant in which a gingiva former with suitable size was screwed followed by buried healing (experiment group) and 30 received traditional flap immediate implant in which a cover screw was screwed followed by buried healing (control group). They were impressed digitally and restored with all-ceramic crown 6 months after the surgery. Implant retention rate, pink esthetic scores, gingival growth and labial bone absorption were detected and compared between two groups. 
RESULTS AND CONCLUSION: The implant retention rates of both groups were 100%. Compared with the control group, the pink esthetic score and gingival growth were significantly increased in the experimental group (P < 0.05), and the labial bone thickness was significantly decreased (P < 0.05). The proximal, distal or mesial gingiva growth was increased a bit in the experimental group compared with the control group, but there was no significant difference between the two groups (P > 0.05). To conclude, the modified flap immediate implant is conducive to soft tissue reconstruction in maxillary aesthetic area.
