The materials used for the abutment can affect strength and aesthetics, so careful consideration is taken when choosing the right abutment for the job. Data from all included studies were then analyzed, compared, and tabulated to satisfy the objectives of the review. By definition, the CDC classifies instruments with bone contact as critical, and therefore these types of instruments must be heat‐sterilized.11, By definition, healing abutments and cover screws are “in‐dwelling” or in‐situ interim devices, and healing abutments and cover screws have traditionally been reused by dentists for economic reasons.4-9 However, the definitions for healing abutments and cover screws as defined by the Glosssary of Oral and Maxillofacial Implants12 and the Glossary of Prosthodontic Terms13 do not specify whether they are reusable. Conversely, due to the popular clinical practice of reusing healing abutments to reduce cost to clinicians and patients, indiscriminate reuse of healing abutments should be avoided, until further supporting evidence is established, and clinicians should evaluate each used healing abutment individually before reuse. Healing Abutment Uni per page. 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. Thereafter, a supplemental electronic search along with a hand search of references of all included articles was conducted using systematic methods.14 Furthermore, as part of the supplemental search, articles that had a lag time to emerge on the PubMed search engine were also screened.

The authors deny any conflicts of interest in regards to the current study. A few authors have reported biological and mechanical concerns related to reuse of healing abutments.6-8 The concerns include the inability to adequately clean the contaminants from the healing abutments before reuse and the functional integrity of the device itself between repeated uses.6-8 Cakan et al noted that resterilization of implant components is controversial in terms of patient safety, ethics, and cost issues.6 Supporters of reusing implant components believe that manufacturers label devices for single use to maintain their profit margin, while opponents believe that the risks outweigh the benefits.6. The specific (patient‐intervention‐control‐outcome) PICO question for this systematic review was: in patients with dental implants, does a reused healing abutment or cover screw compared to an unused new healing abutment result in adverse clinical outcomes, or harm to patients? The average cost of a new healing abutment in the United States from premium implant manufacturers is about 15% of the cost of a dental implant.

However, the biological or mechanical implication of this finding is yet to be determined because presently there are no reports in the literature related to any unfavorable consequences to dental implants, or harm to patients by reuse of healing abutments or cover screws. Dental healing caps are placed in a two stage surgical procedure. The authors concluded that CO2 laser used alone or in combination with hydrogen peroxide may be used clinically for sufficient decontamination of titanium surfaces. After performing bacterial culture sensitivity and careful visual analysis using LED lamps, the authors concluded that used healing abutments sterilized and serviced by dental implant dealers could not remove all contaminants and suggested that clinicians should further clean them again and resterilize them before reuse as a precaution. 3 Retaining Abutment Screws. The Purpose of The Healing Abutment The healing abutment is exposed and a cover screw is taken out enabling the healing cap to be placed instead on top of the dental implant. Limited evidence suggests that routine methods used for cleaning and sterilization of used titanium healing abutments may not result in the complete removal of contaminants.

Scanning electron microscopy analysis showed that there were no detectable differences in the surface appearance of used healing abutments after sterilization. between used healing abutments and new healing abutments. The cover screw was used to cover the fixture-abutment connection part of the implant. The authors recommended physical and detergent cleaning, pure water rinsing, and the use of nonsurface contaminating sterilization techniques. In preparation for this procedure, the dentist must remove the healing cap that was screwed onto the implant at the time of placement and replace it with an appropriately shaped abutment. Healing Abutments and Cover Screws; Important Product Information at Bottom of Page. If the threads of the implants were exposed, the exposed site was grafted with alloplast bone powder (MBCP, Biomatlante, Bretagne, France) and absorbable collagen membrane (Bio-Gide, Geistlich Pharma AG, Wolhusen, Switzerland). Two-stage surgery A cover screw is connected to the implant at implant installation. BONDBONE is a novel synthetic bone graft material considered to be a … Cover Screws Abutments find rotational indexing even at a significant angle to the long axis of the implant. 3.5 x 3mm Healing Abutment, 3.5mm Platform, Internal Hex: HH3530: N/A: 3.5 x 5mm Healing Abutment, 3.5mm Platform, Internal Hex: HH3550: N/A: A cover screw is flush with the surface of the dental implant, and is designed to be completely covered by mucosa. The predetermined inclusion criteria for this systematic review were broad to permit the inclusion of as many articles as possible. All components in this study were analyzed after contamination with Enterococcus faecalis, which the authors considered to be the “gold standard” bacterium when testing for the elimination of pathogens due to its high virulence and resistance to antimicrobials. The healing abutment was removed and replaced with the 1st crown and abutment eight months ago. Cakan et al6 in 2015 investigated whether used healing abutments are properly cleaned and sterilized by dealers and can be safely reused in clinical practice. They collected 60 used healing abutments in sealed sterile pouches from dealers of six implant companies. One additional study showed that routine methods sufficiently resulted in adequate decontamination of used healing abutments.
