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. 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. Nevertheless, 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.
