Abstract

The purpose of this study was to investigate the effects on shear bond strength to resin after pure titanium (Ti) was exposed to plasma under different kinds of gas atmosphere. Polished Ti samples were treated using a plasma exposure apparatus in gas atmospheres of air, CO2, and C3F8. Surface analysis of Ti exposed to plasma was achieved through surface free energy and XPS measurements. The Ti sample was bonded with adhesive resin (4-META, MAC-10, HEMA, MDP, VBATDT) to a stainless steel piece. After which, shearing adhesion test was done. It was observed that plasma exposure in a specific gas atmosphere in regulated the bonding strength of titanium surface to resin. Based on the results of this study, we concluded that plasma exposure was a useful surface treatment method for dental practices.

摘要

本研究的目的是探究纯钛（Ti）在不同气体气氛下暴露于等离子体后对与树脂的剪切粘结强度的影响。将经过抛光的Ti样品在空气、CO2和C3F8的气体气氛中使用等离子体暴露装置进行处理。通过表面自由能和XPS测量对暴露于等离子体的Ti进行表面分析。将Ti样品用粘结树脂（4-META、MAC-10、HEMA、MDP、VBATDT）粘结到不锈钢片上。之后，进行剪切粘结试验。观察到在特定气体气氛中进行等离子体暴露可调节钛表面与树脂的粘结强度。基于本研究结果，我们得出结论，等离子体暴露是一种对牙科实践有用的表面处理方法。
