Abstract: Objective：To evaluate the peri-implant marginal bone loss and gingiva condition of immediate flapless implants within 6 months after implantation. Methods: 18 cases were performed flapless operations of immediate implantation for 22 dental implants. Alveolar bone height  and the gingival attachment level mesial and distal to implants were surveyed and recorded during operations. Immediate restorations without teeth contact were given when the patient was light overbite and overjet. All cases were given final restorations after 6 months. Bone level and gingival attachment were also recorded in the 3rd and 6th months after operations. Results: X-ray radiographs showed that all implants were well osseointegrated. Radiographic examination yielded (0.47±0.03) mm medial and (0.56±0.06) mm distal bone level loss respectively in 3 months after implantation. The medial and distal papilla shrinkage were (0.41±0.05) mm and (0.53±0.03) mm respectively. 6 months after operation, medial and distal bone level loss were (1.60±0.05) mm and (1.73±0.04) mm, while papilla shrinkage were (0.51±0.03) mm and (0.62±0.04) mm. Conclusions: The immediate flapless implantation may lead to less bone loss and papilla shrinkage than delayed implantation.

摘要： 目的：评测前牙区不翻瓣即刻牙种植的近期临床效果及软硬组织变化。方法：2008-07—2012-11于同济大学附属口腔医院种植科就诊的患者中，选择上颌前牙无法保留，适合采取即刻不翻瓣种植的患者纳入实验。于术中，术后3个月、6个月分别测量缺失牙近、远中骨高度及牙龈乳头的高度。结果：共18例患者22颗患牙纳入本研究。X线结果表明种植体均形成良好骨结合。种植后3个月，牙槽骨唇颊侧骨板近、远中吸收分别为(0.47±0.03)mm和(0.56±0.06)mm；6个月时骨吸收分别为(1.60±0.05)mm和(1.73±0.04)mm。 种植3个月时，近、远中牙龈附着退缩为(0.41±0.05)mm和(0.53±0.03)mm，6个月牙龈时附着退缩分别为(0.51±0.03)mm和(0.62±0.04)mm。结论：前牙区不翻瓣即刻牙种植能良好地保存种植体周围骨组织及软组织高度，在选择合适适应证的条件下，能在减少手术创伤的基础上获得良好的修复效果。
