Abstract

This study aimed to introduce a minimally invasive technique for maxillary sinus floor elevation using the lateral approach (lSFE) and to determine the factors that influence the stability of the grafted area in the sinus cavity. Thirty patients (30 implants) treated with lSFE using minimally invasive techniques from 2015 to 2019 were included in the study. Five aspects of the implant (central, mesial, distal, buccal, and palatal bone heights [BHs]) were measured using cone-beam computed tomography (CBCT) before implant surgery, immediately after surgery (T0), 6 months after surgery (T1), and at the last follow-up visit (T2). Patients' characteristics were collected. A small bone window (height, (4.40 ± 0.74) mm; length, (6.26 ± 1.03) mm) was prepared. No implant failed during the follow-up period (3.67 ± 1.75) years. Three of the 30 implants exhibited perforations. Changes in BH of the five aspects of implants showed strong correlations with each other and BH decreased dramatically before second-stage surgery. Residual bone height (RBH) did not significantly influence BH changes, whereas smoking status and type of bone graft materials were the potentially influential factors. During the approximate three-year observation period, lSFE with a minimally invasive technique demonstrated high implant survival rate and limited bone reduction in grafted area. In conclusion, lSFE using minimally invasive techniques was a viable treatment option. Patients who were nonsmokers and whose sinus cavity was filled with deproteinized bovine bone mineral (DBBM) had significantly limited bone resorption in grafted area.

上颌外侧窦底抬高的微创技术:小外侧窗口和一期手术-一项2-5年回顾性研究。
本研究旨在介绍一种采用外侧入路(lSFE)进行上颌窦底提升的微创技术,并确定影响移植物区在窦腔内稳定性的因素。本研究纳入2015 - 2019年采用微创技术进行lSFE治疗的30例患者(30颗种植体)。在种植术前、术后即刻(T0)、术后6个月(T1)和最后一次随访时(T2),采用锥形束计算机断层扫描(CBCT)测量种植体的五个方面(中央、中、远端、颊和腭骨高度[BHs])。收集患者的特征。小骨窗(高度,(4.40±0.74)mm;长度为(6.26±1.03)mm。随访(3.67±1.75)年,无种植体失败。30个种植体中有3个出现穿孔。种植体五个方面的BH变化具有很强的相关性,二期手术前BH明显下降。残余骨高度(RBH)对骨高度变化无显著影响,而吸烟状况和植骨材料类型是潜在的影响因素。在大约三年的观察期间,微创技术的lSFE显示出高的种植体存活率和有限的移植区域骨复位。总之,采用微创技术的lSFE是一种可行的治疗选择。不吸烟且窦腔内填充脱蛋白牛骨矿物质(DBBM)的患者移植区骨吸收明显受限。
