In‐Vitro Study of the Contamination Remaining on Used Healing Abutments after Cleaning and Sterilizing in Dental Practice
Bibliographic record
Abstract
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.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
