Abstract

Sterilization is required for any biomedical device intended to be used in contact with the human body. Several studies have reported alterations in the bulk and surface properties of such devices after repeated sterilization cycles. These surface modifications may influence other clinical parameters. Therefore, the aim of this study was to investigate the surface and chemical properties of implant scan bodies (SBs) after consecutive autoclave sterilization procedures. : The objective was to analyze the scan bodies using Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) for chemical analysis and an optical profilometer to analyze the surface roughness. : FTIR spectra depicted the appearance of peak at 1741 and 1100 cm due to the diphenyl ether band disappearance. The XPS spectra showed alterations in the elemental composition after autoclaving and roughness were significantly reduced in PEEK BL and TL SBs. These results indicated that some surface modifications were induced by repeated sterilization cycles.

摘要

任何打算用于与人体接触的生物医学设备都需要进行灭菌处理。几项研究报告称，此类设备在经过多次灭菌循环后，其整体和表面特性会发生改变。这些表面改性可能会影响其他临床参数。因此，本研究的目的是调查连续高压灭菌程序后种植体扫描体（SBs）的表面和化学性质。：目的是使用傅里叶变换红外光谱（FTIR）和X射线光电子能谱（XPS）对扫描体进行化学分析，并使用光学轮廓仪分析表面粗糙度。：FTIR光谱显示，由于二苯醚带消失，在1741和1100 cm处出现了峰。XPS光谱显示高压灭菌后元素组成发生了变化，PEEK BL和TL SBs的粗糙度显著降低。这些结果表明，反复的灭菌循环会引起一些表面改性。
