背景:在下智齿手术的术后并发症中,肿胀被患者认为是最有损伤的,具有社会和生物学影响,并影响患者的生活质量。该研究的目的是评估在下颌阻生第三磨牙拔除中使用钻孔钻与压电器械进行截骨后的肿胀,使用面部重建软件。
方法:随机,裂口,对患者进行了单盲研究,年龄在18到40岁之间,需要拔除下第三磨牙,并在墨西哥大学牙科学院口腔外科部门转诊。根据以下标准,在8个月的时间内招募了22名患者:良好的一般健康状况;双边,对称,影响第三磨牙;没有使用会影响或改变伤口愈合的药物;没有颞下颌关节紊乱病史;没有吸烟。所有患者均行双侧手术切除。对于每个病人来说,在手术前进行面部扫描.进行了两次提取,以随机的方式,用旋转毛刺截骨或使用压电手术器械。在外科手术后3天和7天重复面部扫描。使用专用软件通过叠加计算体积差异。所得数据采用配对t检验处理。
结果:从我们的研究中获得的结果表明,两组在术后肿胀方面没有显着差异。据我们所知,这项研究代表了首次使用可重复收集患者临床参数的客观方法的经验.
结论:3D数字分析,在面部肿胀的评估中,是一种简单的应用技术,目标,可重复,可靠,减少错误的变量。基于这些数据,可以得出结论,压电手术是在第三磨牙手术中进行截骨术的安全方法。然而,关于术后肿胀,与经典旋转仪器相比,它没有优势。

Among the post-surgical complications of lower wisdom teeth surgery, swelling is considered by patients one of the most impairing, with both social and biological influences and impacting patients\' quality of life. Aim of the study was to evaluate the swelling following the osteotomy when performed with drilling burs versus piezo-electric instruments in the mandibular impacted third molar extraction, using a facial reconstruction software.
A randomized, split-mouth, single-blind study was conducted on patients, ranging between 18 and 40 years of age, requiring lower third molars extraction and referred at the Oral Surgery Unit of the School of Dentistry of the University of Messina. Twenty-two patients were recruited during an 8 months period according to the following criteria: good general health conditions; bilateral, symmetrical, impacted third molars; no use of medication that would influence or alter wound healing; no temporomandibular joint disorder history; no smoking. All patients underwent bilateral surgical removal. For each patient, a facial scan was obtained prior to the surgical procedures. The two extractions were conducted performing, in a randomized way, osteotomy with rotatory burs or use of piezo surgical instruments. Facial scans were repeated at 3 and 7 days after the surgical procedures. Volumetric differences were calculated via superimposition using a dedicated software. The data obtained were processed using paired t-test.
The results obtained from our study showed no significant differences between two groups regarding post-operative swelling. To the best of our knowledge, this study represents the first experience of using an objective method that can be reproducible on the collection of patients\' clinical parameters.
The 3D digital analysis, in the evaluation of facial swelling, is a technique of simple application, objective, reproducible, reliable, decreasing the variables of error. Based on these data, it is possible to conclude that piezo surgery is a safe way for performing the osteotomies during third molar surgery. However, regarding the post-operative swelling, it does not show an advantage over classical rotary instruments.
