The present study assessed the three-dimensional bone loss, at three different levels, around implants placed immediately after extraction using the socket shield method versus immediate implant placement.
A non-randomized clinical trial was conducted in 30 cases divided into two groups: socket shield method and immediate implant placement (15 cases each). Horizontal bone width (HBW) (at three different levels from baseline) and vertical bone level (VBL) (mesial and distal surfaces of the implant) were measured preoperatively and 6 months postoperatively by using cone beam computed tomography and radio visio graphy.
The mean difference at 2-mm and 8-mm HBW from the baseline was better in the socket shield technique, although the results were not significant. Significant results were found in Levene's test for equality of error variances. The VBL was significant at both the distal and mesial surfaces of the implant.
The socket shield approach demonstrated promising clinical outcomes in preserving alveolar ridge morphology. It can be utilized as a substitute for the typical instantaneous implant placement in the aesthetic zone.
本研究评估了采用牙槽窝保护法在拔牙后即刻植入种植体与即刻种植相比，在三个不同水平的三维骨吸收情况。
进行了一项非随机临床试验，30例患者分为两组：牙槽窝保护法组和即刻种植组（每组15例）。术前及术后6个月使用锥形束计算机断层扫描和放射影像测量水平骨宽度（HBW）（距基线三个不同水平处）和垂直骨水平（VBL）（种植体的近中和远中面）。
牙槽窝保护技术在距基线2mm和8mm处的水平骨宽度平均差异更好，尽管结果不显著。在误差方差齐性的Levene检验中发现了显著结果。种植体远中面和近中面的垂直骨水平均有显著差异。
牙槽窝保护法在保留牙槽嵴形态方面显示出有前景的临床效果。它可作为美学区域典型即刻种植的替代方法。
