“…In an evidence-based profession where the practice of sterilizing and reusing these implant components is becoming common in clinical practice, research to verify the safety and validity of this practice is necessary. Although not ideal, studies show promising results with respect to achieving decontamination in used healing abutments (Stacchi et al 2018; Sánchez-Garcés et al 2019; Almehmadi 2021; Kyaw et al 2020; Sahin and Dere 2021). However, the authors recommend further research including RCTs to establish standard protocols in achieving complete resterilization of used HAs.…”

Introduction: Although healing abutments are designated for single use by most implant manufacturers, it is common practice for clinicians to reuse healing abutments. However, there is a lack of adequate references that describe detailed sterilization protocols for reuse of healing abutments. Objectives: The purpose of this systematic review was to compile, organize, and describe the most common techniques for the sterilization of healing abutments and their efficiency in eliminating traces of microorganisms. Methods: An electronic search in 5 different databases was performed, including the National Library of Medicine (MEDLINE via PubMed), Embase, Cochrane Central Register of Controlled Trials, Web of Science, and Google Scholar from January 2000 to December 2020. Search variables included were dental implant, healing abutment, contaminate, contamination, reuse, and sterilization. Studies reporting with a minimum sample size of 10 healing abutments (5 per group) published in the English language were evaluated. Risk of bias assessment was elaborated for included investigations. Results: In total, 812 articles were identified, of which 8 were included in the analysis. Steam autoclave was the most widely used form of resterilization. Not a single protocol, however, was able to achieve 100% virgin surface of the healing abutments. Conclusion: Although reuse of dental implant healing abutments is a cost-effective measure in dental practice, thorough surface decontamination followed by resterilization is highly recommended before reuse. Knowledge Transfer Statement: With consideration of cost and patient preference, results of this review would be useful in knowing various sterilization protocols for reusing healing abutments that could lead to more appropriate therapeutic decisions.

“…The main reason for considering abutments as disposable and non-reusable could be their intrinsic susceptibility to contamination and thread wear. These factors, if left unaddressed, have the potential to induce harm to not only the internal structure of the implant but also the engagement area of the screw, and even the overall composition of the titanium material [9][10][11]. Nevertheless, it is noteworthy that the practice of utilizing sterilized HAs across multiple procedures is commonplace [4].…”

Aim: The objective of this in vitro study was to compare reused and sterilized versus new healing abutments to assess whether a decontamination and sterilization process performed on resued healing abutments was sufficient to remove residual proteins. The two groups were comparable with respect to patient safety. Materials and methods: During the period from September 2022 to October 2023, healing abutment screws were selected and divided into two groups according to whether they were new or previously used in patients. The samples were subjected to a decontamination and sterilization protocol, and results from sample sterility evaluation and assessment of surface protein levels were recorded. Results: The obtained results revealed a significant difference in the OD562 nm values between new and reused healing abutment samples. The assay demonstrates how treated healing abutments were still contaminated by residual proteins. Conclusion: Within the limitations of the present study, although from an infectious point of view sterilization results in the total eradication of pathogens, surface proteins remain on reused healing abutments.

“…1 In the past decade, there have been controversial arguments about the ethics, safety, and economic benefits of reusing healing abutments (HAs), while manufacturers have advocated for single use. Recent studies [2][3][4][5][6] have indicated that a completely cleaned surface of HAs could not be achieved with conventional cleaning procedures, raising concerns about the potential for cross-contamination and inflammation of soft tissue around dental implants.…”

Objective: To evaluate the efficacy of four decontamination protocols on contaminated healing abutments (HAs) and their effects on surface topography. Methods: Eighty contaminated single-use HA samples collected from human participants were stained with phloxine B and examined microscopically. The retrieved HAs were randomly divided into four test groups: (1) Autoclaving only (AU), (2) 5.25% sodium hypochlorite (NaOCl) + AU, (3) Electrochemical treatment (EC) + AU, (4) NaOCl + EC + AU, and positive control (contaminated without any treatment).Four new unused HAs served as negative controls (NC). The surface features were analyzed using stereo microscopy (SM), scanning electron microscopy (SEM), energydispersive X-ray spectroscopy (EDS), and optical profilometry.Results: The lowest decontamination efficacy was observed for the AU group. The NaOCl + AU and EC + AU groups effectively removed residual contamination, whereas EC + AU showed better decontamination results than NaOCl + AU. SM, SEM, and EDS analyses revealed the best decontamination efficacy in the combined NaOCl + EC + AU group compared to the other groups. Surface roughness (Sa), developed surface area ratio (Sdr), and texture-aspect ratio (Str) in AU, NaOCl + AU, EC + AU, and NaOCl + EC + AU groups were not statistically significant compared to the NC group. Conclusions:The combination of NaOCl with subsequent EC can remove soft and hard deposits from the surface of HAs compared to NaOCl alone and EC alone, without altering the surface topography of HAs.
