Osseointegration is defined as the direct structural and functional connection between neo-formed bone and dental implants. Among the parameters suggested to predominantly influencing the establishment of a successful osseointegration is the quality of the implant surface, which may enhance the strength and speed of this biomechanical process.
The purpose of this study was to evaluate the ability of a novel laser-treated surface, compared to sandblasted, large-grit, acid-etched (SLA) surfaces, to enhance and accelerate implant integration in delayed implant placement. Thirty patients with two missing posterior teeth were enrolled in this study. Each patient received, at a randomly allocated site, an implant with a conventional SLA surface, and at a second site, an implant with laser-textured surface. A total of 60 tissue-level implants were subsequently placed. Implant stability (ISQ) was measured using resonance frequency analysis (RFA). ISQ was assessed at baseline (T0), 8 weeks (T1), and 12 weeks (T2) following implant placement. There was a statistical difference in implant stability between laser-textured and SLA group at 12 weeks postoperatively. Implant stabilization showed a successful osseointegration with both surface types.
Both laser and SLA surface treatments had positive impacts on implant stabilization following delayed placement. Laser-treated surfaces presented higher values of osseointegration at 3 months postoperatively.
骨结合被定义为新形成的骨组织与牙种植体之间直接的结构和功能连接。在众多被认为对成功建立骨结合起主要影响的参数中，种植体表面质量是其中之一，它可能会增强这一生物力学过程的强度和速度。
本研究旨在评估一种新型激光处理表面与喷砂、大颗粒、酸蚀（SLA）表面相比，在延迟种植体植入时增强和加速种植体整合的能力。30例有两颗后牙缺失的患者纳入本研究。每位患者在随机分配的部位植入一枚具有传统SLA表面的种植体，在另一个部位植入一枚具有激光纹理表面的种植体。随后共植入60枚组织水平种植体。使用共振频率分析（RFA）测量种植体稳定性（ISQ）。在种植体植入后的基线（T0）、8周（T1）和12周（T2）评估ISQ。术后12周时，激光纹理组和SLA组的种植体稳定性存在统计学差异。两种表面类型的种植体稳定均显示出成功的骨结合。
激光和SLA表面处理对延迟植入后的种植体稳定均有积极影响。激光处理表面在术后3个月时呈现出更高的骨结合值。
