The purpose of this study is to evaluate residual contamination of healing abutments sterilized by dealers of dental implant companies.
Healing abutments collected from dealers of different implant companies were randomly numbered, and they were examined for visible deformation and contamination on the abutment surface, packaging errors, and presence of a sterilization indicator. The healing abutments were stained with a dye solution for contamination detection and evaluated by dividing into different regions. The presence of residual contamination was examined through photographic images taken from the healing abutments and the data obtained were recorded. Pearson's chi-square analysis was used to evaluate the relation between implant brands and contamination status. Significance was evaluated as p <0.05.
Visible residual contamination was detected in approximately 31% of the healing abutments. After the staining procedure, in the visual assessment of the stained surfaces, residual contamination was found in at least one region of all healing abutments except one (n=176, 99.4%). The most intense staining was seen in the screw driver hole (n=172, 97.1%), body (n=113, 63.8%), occlusal (n=107, 60.4%), screw (n=79, 44.6%), and connector (n=72, 40.6%) regions, respectively. A significant relationship was found between the brands and the contamination status (p <0.05).
The reuse of healing abutments is not suitable, as it does not ensure optimum cleaning and sterilization, and it is not possible to eliminate contaminants completely.
Despite the economic benefits of multiple use of healing abutments, disadvantages should be carefully evaluated by clinicians.
本研究旨在评估由牙科种植体公司经销商进行消毒的愈合基台是否存在残留污染。
从不同种植体公司经销商处收集愈合基台，对其进行可见变形和基台表面污染、包装错误以及是否存在灭菌指示物的检查。用染料溶液对愈合基台进行污染检测，并进行分区评估。通过从愈合基台拍摄的照片检查是否存在残留污染，并记录获得的数据。采用皮尔逊卡方检验评估种植体品牌与污染状况之间的关系。以 p<0.05 为差异有统计学意义。
约 31%的愈合基台可见残留污染。经过染色程序后，在染色表面的目视评估中，除一个愈合基台（n=176，99.4%）外，所有愈合基台的至少一个区域均发现残留污染（n=176）。在螺丝刀孔（n=172，97.1%）、体部（n=113，63.8%）、咬合面（n=107，60.4%）、螺丝（n=79，44.6%）和连接体（n=72，40.6%）区域的染色最为严重。品牌与污染状况之间存在显著关系（p<0.05）。
愈合基台的重复使用并不合适，因为它不能确保最佳的清洁和消毒，并且不能完全消除污染物。
尽管愈合基台多次使用具有经济优势，但临床医生应仔细评估其缺点。
