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.
