Peri-implantitis is a common complication characterized by inflammation in tissues surrounding dental implants due to plaque accumulation, which can lead to implant failure. While air flow abrasive treatment has been found to be effective for debriding implant surfaces, little is known about the factors that affect its cleaning capacity. This study systematically examined the cleaning capacity of air powder abrasive (APA) treatment with β-tricalcium phosphate (β-TCP) powder, using various powder jetting strengths and different particle sizes. Three sizes of β-TCP powder (S, M, and L) were prepared, and different powder settings (low, medium, and high) were tested. The cleaning capacity was determined by quantifying ink removal, which simulated biofilm removal from the implant surfaces at different time points. The results of the systematic comparisons showed that the most efficient cleaning of implant surfaces was achieved using size M particles with medium setting. Additionally, the amount of powder consumed was found to be critical to cleaning efficiency, and the implant surfaces were altered in all tested groups. These systematically analyzed outcomes may provide insights into the development of potential non-surgical strategies for treating peri-implant diseases.
种植体周围炎是一种常见的并发症，其特征为由于菌斑积聚导致种植体周围组织炎症，从而导致种植体失败。虽然已经发现空气动力喷砂处理对于去除种植体表面的附着物是有效的，但对于影响其清洁能力的因素知之甚少。本研究系统地检查了使用不同粉末喷射强度和不同粒径的β-磷酸三钙（β-TCP）粉末的空气粉末喷砂（APA）处理的清洁能力。制备了三种不同粒径的β-TCP 粉末（S、M 和 L），并测试了不同的粉末设置（低、中、高）。通过定量去除墨迹来确定清洁能力，墨迹模拟了不同时间点从种植体表面去除生物膜。系统比较的结果表明，使用中等设置的 M 粒径颗粒可以最有效地清洁种植体表面。此外，发现粉末的消耗量对于清洁效率至关重要，并且在所有测试组中，种植体表面都发生了改变。这些经过系统分析的结果可能为开发治疗种植体周围疾病的潜在非手术策略提供了一些思路。
