Despite several reports on the clinical outcomes of flapless implant surgery, limited information exists regarding the clinical conditions after flapless implant surgery.
The objective of this study was to evaluate the soft tissue conditions and marginal bone changes around dental implants 1 year after flapless implant surgery.
For the study, 432 implants were placed in 241 patients by using a flapless 1-stage procedure. In these patients, peri-implant soft tissue conditions and radiographic marginal bone changes were evaluated 1 year after surgery.
None of the implants were lost during follow-up, giving a success rate of 100%. The mean probing depth was 2.1 mm (SD 0.7), and the average bleeding on probing index was 0.1 (SD 0.3). The average gingival index score was 0.1 (SD 0.3), and the mean marginal bone loss was 0.3 mm (SD 0.4 mm; range 0.0-1.1 mm). Ten implants exhibited bone loss of >1.0 mm, whereas 125 implants experienced no bone loss at all.
The results of this study demonstrate that flapless implant surgery is a predictable procedure. In addition, it is advantageous for preserving crestal bone and mucosal health surrounding dental implants.
尽管已有多篇关于无瓣种植手术临床结果的报道，但关于无瓣种植手术后的临床情况，相关信息有限。
本研究的目的是评估无瓣种植手术后1年牙种植体周围的软组织状况和边缘骨变化。
在本研究中，采用无瓣一期手术为241例患者植入了432颗种植体。对这些患者在术后1年评估种植体周围软组织状况和影像学边缘骨变化。
随访期间无种植体脱落，成功率为100%。平均探诊深度为2.1毫米（标准差0.7），平均探诊出血指数为0.1（标准差0.3）。平均牙龈指数评分为0.1（标准差0.3），平均边缘骨吸收为0.3毫米（标准差0.4毫米；范围0.0 - 1.1毫米）。10颗种植体骨吸收>1.0毫米，而125颗种植体完全没有骨吸收。
本研究结果表明，无瓣种植手术是一种可预测的手术方法。此外，它有利于保留牙种植体周围的牙槽嵴骨和黏膜健康。
