Analysis of the in vitro efficacy of non-surgical and surgical dental implant surface decontamination with or without suprastructure.
Three hundred and sixty implants were dipped in indelible red and distributed to 30°, 60°, or 90° angulated bone defect models. One hundred and twenty implants were used for each bone defect, 40 of which were assigned to a decontamination method (CUR: curette; SOSC: soundscaler; APA: air powder abrasion). Of these, 20 were subjected to a simulated non-surgical (NST) or surgical treatment (ST), with/without mucosa mask, of which 10 were carried out with (S+) or without (S-) suprastructure. Uncleaned implant surface was assessed by both-sided implant surface photography. Surface morphology changes were analyzed using scanning electron microscopy (SEM).
Cleaning efficacy was significantly better within NST if the suprastructure was removed (p < 0.001). No significant difference was found within ST (p = 0.304). Overall, cleaning efficacy in the order APA > SOSC>CUR decreased significantly (p < 0.0001) for both S+ and S- in NST as well as ST. Separated by NST/ST, S+/S-, defect angulation and decontamination method, only isolated significant differences in cleaning efficacy were present. Linear regression analysis revealed significant associations of remnants with the treatment approach, decontamination method, and defect angle (p < 0.0001). SEM micrographs showed serious surface damage after use of CUR and SOSC.
Suprastructure removal is an additional option to improve cleaning efficacy of non-surgical implant surface decontamination in this in vitro model.
分析非手术和手术条件下，有无上部结构时，对牙科植入物表面进行去污的体外疗效。
将 360 个不可磨灭红色染料浸染的种植体分别放置于 30°、60°和 90°牙槽骨缺损模型中。每个骨缺损模型使用 120 个种植体，其中 40 个种植体用于不同的去污方法（CUR：刮治器；SOSC：超声器械；APA：空气动力喷砂）。其中，20 个种植体用于模拟非手术（NST）或手术（ST）处理，有/无黏膜保护，其中 10 个有/无上部结构。通过双侧种植体表面摄影评估未清洁的种植体表面。使用扫描电子显微镜（SEM）分析表面形貌变化。
如果去除上部结构，NST 时的清洁效果明显更好（p<0.001）。ST 时无显著差异（p=0.304）。总体而言，NST 和 ST 时，S+和 S-均为 APA>SOSC>CUR，清洁效果呈显著下降趋势（p<0.0001）。根据 NST/ST、S+/S-、缺损角度和去污方法进行分组，只有在 NST/ST、S+/S-、缺损角度和去污方法的清洁效果方面存在显著差异。线性回归分析显示，残留物与治疗方法、去污方法和缺损角度之间存在显著相关性（p<0.0001）。SEM 显微照片显示，CUR 和 SOSC 使用后表面严重受损。
在该体外模型中，去除上部结构是提高非手术种植体表面去污效果的附加选择。
