The aim of this study was to estimate the influence of flap design on alveolar osteitis (AO) and postoperative side effects following third molar surgery.
This study was designed as a randomized single-blind clinical trial. The predictor variable was flap type. Envelope flap and modified triangular flap techniques were used. The primary outcome variable was AO. The secondary outcome variables were pain, swelling, and trismus. Descriptive and bivariate statistics were computed. Statistical significance was set at P ≤ .05.
Eighty patients with impacted mandibular third molars participated in the study. The envelope flap design was associated with a higher incidence of AO that was not statistically significant. On the second day, postoperative pain and swelling was observed as significantly different with the envelope flap technique.
The modified triangular flap had the advantage of less postoperative pain and swelling but had the disadvantage of AO.
本研究旨在评估瓣设计对第三磨牙手术后牙槽骨炎（AO）和术后副作用的影响。
本研究设计为随机单盲临床试验。预测变量为瓣类型。使用信封瓣和改良三角瓣技术。主要结局变量为 AO。次要结局变量为疼痛、肿胀和牙关紧闭。计算描述性和双变量统计数据。统计学意义设定为 P ≤.05。
80 名下颌阻生第三磨牙患者参加了这项研究。信封瓣设计与 AO 发生率较高相关，但无统计学意义。术后第二天，观察到信封瓣技术的术后疼痛和肿胀有显著差异。
改良三角瓣的优点是术后疼痛和肿胀较轻，但缺点是 AO。
