This study evaluated, in vitro, the effects of different instrumentations used in the treatment of peri-implantitis on implant surfaces coated with hydroxyapatite or titanium plasma spray (TPS).
There were 14 cylindrical rough implants used, including 7 hydroxyapatite and 7 TPS coated. Split in 2 parts for a total of 24 experimental surfaces, implants were treated with a stainless-steel curette, plastic curette, ultrasonic scaler tip, and air-powder-water spray. There was 1 hydroxyapatite and 1 TPS implant used as controls. Profilometry and scanning electron microscopy were used to examine instrumented surfaces for variations in surface topography.
All experimental procedures determined changes on tested rough implant surfaces. Such alterations were related to the implant coating material, and the procedure consisting in coating removal and/or leveling of surface roughness.
Although a plastic curette and air-powder-water spray induced less implant surface alterations, these instrumentations left deposits on the surface that may affect, in vivo, the tissue healing process.
本研究在体外评估了用于治疗种植体周围炎的不同器械处理方法对涂有羟基磷灰石或钛等离子喷涂（TPS）的种植体表面的影响。
使用了14个圆柱形粗糙种植体，其中7个涂有羟基磷灰石，7个涂有TPS。将种植体分成两部分，共24个实验表面，分别用不锈钢刮匙、塑料刮匙、超声洁治器尖端和气粉水喷雾进行处理。使用1个涂有羟基磷灰石的种植体和1个涂有TPS的种植体作为对照。采用轮廓测定法和扫描电子显微镜检查处理后的表面，以观察表面形貌的变化。
所有实验操作均导致测试的粗糙种植体表面发生变化。这些改变与种植体涂层材料有关，且与涂层去除和/或表面粗糙度平整的操作有关。
尽管塑料刮匙和气粉水喷雾引起的种植体表面改变较少，但这些器械处理会在表面留下沉积物，可能在体内影响组织愈合过程。
