There were no studies identified in the literature that reported on any adverse consequences to dental implants, such as infections, bone loss, mechanical complications, implant failure, or harm to patients, by reuse of healing abutments or cover screws. All six articles reported observational studies, which used samples of used healed abutments obtained from patients, and there were no true clinical studies on the reuse of healing abutments identified in this systematic review. First, due to the nature of the topic and PICO question posed in this systematic review, no quantitative data were identified and thus no statistical analysis was performed. According to the United States Food and Drug Administration, reusable medical devices have been defined as devices that health care providers can reprocess and reuse on multiple patients.1 Reusable medical devices can either be ad‐hoc (used for a specific purpose before reprocessing and reuse on another patient) or in situ (in place for a period of time in one patient's body and then removed, reprocessed, and reused on another patient).

Third, the search was restricted to English language peer‐reviewed journals to minimize problems of interpretation; however, a recent empirical study has shown minimal consequences of exclusion or inclusion of trials published in non‐English languages on combined effect estimates in meta‐analyses of Randomized clinical trials (RCTs).15 Similar to most systematic reviews, despite a comprehensive search process, it is probable that the authors did not identify any pertinent articles in the search process.16 We did not consider gray literature in this systematic review due to the nonpeer‐reviewed nature of such articles and potential for biased information.17, The purported disadvantages of reusing healing abutments in implant dentistry include potential for cross contamination between patients, potential for soft tissue inflammation and unfavorable response, potential for marginal bone loss, and possible mechanical issues related to stripping of the screwdriver slot or connection with the implant.4-8 On the other hand, the advantages of reusing healing abutments are tangible to the clinician and include reduced cost, which is usually transferable to the patient, reduced need for larger inventory in the dental office, and reduction in solid medical waste and decreased environmental impact, which is a prevailing concern across all medical specialties.4-8, 18. Item #: TP3NHA2. The cover screws were then cleaned by using citric acid, sterile water, hydrogen peroxide, and CO2 laser alone or with a combination of these. The thickness of the fibrous capsule and the number of macrophages within the capsule were used as surrogate markers to measure soft tissue response. Based on the elimination of pathogens, the authors reported that using the routine sterilization methods, the sterility of used components was equal to new components without any visible mechanical distortion. One additional study showed that routine methods sufficiently resulted in adequate decontamination of used healing abutments. This represents a significant expense to the clinician's overhead expenditure and can allow the transfer of cost savings to the patients, or at least curtail the increasing price of implant therapy. There were no true clinical studies identified. A two stage dental implant involves placing a cover screw on the implant and closing the gums tissue over it during the healing process.

Three studies reported that routine methods used for cleaning and sterilizing used healing abutments did not result in the complete removal of contaminants, while two studies4, 9 showed that routine methods supplemented with an additional regimen, such as CO2 laser and sodium hypochlorite treatment, resulted in adequate decontamination. This protocol can help to mitigate medical‐legal risk and impact dental public health in a profound way.
