BACKGROUND
Reuse or "recycle" of dental implant healing abutments in clinical practice is common, primarily for economic rational.
PURPOSE
To determine of this practice results in reuse of components that carry with them some degree of contamination between patients, even following thorough cleaning and sterilization.
MATERIALS AND METHODS
One hundred healing abutments were collected from eight clinicians following patient use. The abutments were cleaned, sterilized, and then collected. The samples were treated with a protein specific stain (Phloxine B), and photographed.
RESULTS
Ninety-nine percent of the abutments showed protein contamination at one or more sites following cleaning and sterilization.
CONCLUSION
Reuse of healing abutments between patients should be reevaluated in light of this data.
背景
在临床实践中，牙科种植愈合基台的再利用或“回收”很常见，主要是出于经济合理性。
目的
确定这种做法是否会导致在患者之间重复使用带有一定程度污染的部件，即使经过彻底清洁和消毒之后。
材料与方法
从八位临床医生处收集了患者使用后的100个愈合基台。对基台进行清洁、消毒，然后收集。样本用蛋白质特异性染色剂（焰红B）处理并拍照。
结果
99%的基台在清洁和消毒后一个或多个部位显示出蛋白质污染。
结论
鉴于这些数据，应重新评估患者之间愈合基台的再利用情况。
