To evaluate the safety and efficiency of novel ultrasonic scaler tips, conventional stainless-steel tips, and plastic tips on titanium surfaces.
Mechanical instrumentation was carried out using conventional ultrasonic scalers (EMS, Nyon, Switzerland) with novel metallic implant tip (BS), a plastic-headed tip (ES), a plastic tip (PS) and a conventional stainless-steel tip (CS) on 10 polished commercially pure titanium disks (Grade II) per group. Arithmetic mean roughness (R(a) ) and maximum height roughness (R(y) ) of titanium samples were measured and dissipated power of the scaler tip in the tip-surface junction was estimated to investigate the scaling efficiency. The instrumented surface morphology of samples was viewed with a scanning electron microscope (SEM) and surface profile of the each sample was investigated using contact mode with a commercial atomic force microscope (AFM).
There were no significant differences in surface roughness (R(a) and R(y) ) among BS, ES, and PS group. However, CS group showed significant higher surface roughness (R(a) and R(y) ). The efficiency of CS tip is twice as much higher than that of BS tip, the efficiency of BS tip is 20 times higher than that of PS tip, and the efficiency of BS tip is 90 times higher than that of ES tip.
Novel metallic copper alloy ultrasonic scaler tips may minimally influence the titanium surface, similar to plastic tip. Therefore, they can be a suitable instrument for implant maintenance therapy.
评估新型超声洁牙机头、传统不锈钢机头和塑料机头在钛表面的安全性和效率。
使用新型金属种植体机头（BS）、塑料机头（ES）、塑料机头（PS）和传统不锈钢机头（CS）对每组 10 个抛光商用纯钛盘（II 级）进行常规超声洁牙器（EMS，瑞士尼永）的机械器械处理。测量钛样本的算术平均粗糙度（R(a)）和最大高度粗糙度（R(y)），并估计洁牙机头在机头-表面交界处的耗散功率，以研究洁牙效率。使用扫描电子显微镜（SEM）观察样本的仪器化表面形态，并使用商业原子力显微镜（AFM）以接触模式研究每个样本的表面轮廓。
BS、ES 和 PS 组之间的表面粗糙度（R(a)和 R(y)）没有显著差异。然而，CS 组的表面粗糙度（R(a)和 R(y)）显著更高。CS 机头的效率比 BS 机头高两倍，BS 机头的效率比 PS 机头高 20 倍，BS 机头的效率比 ES 机头高 90 倍。
新型金属铜合金超声洁牙机头可能对钛表面的影响最小，类似于塑料机头。因此，它们可以成为种植体维护治疗的合适器械。
