When people hear the word “rejection” in connection with implants, they are usually describing conditions that can occur where there has been surgery that involves transplanting a vital organ such as a heart. However, dental implants fall into an entirely different category due to the fact that tissue matching, blood typing, etc., is not a factor in dental implants. The body completely accepts placement of dental implant material (like orthopedic materials which are similar) within bone; therefore, today’s dental implants meet with great success. Obviously, there are some dental implants that have not been successful. However, success has more to do with proper patient selection, proficiency of the practitioner, and the patient’s commitment to proper hygiene and preventive maintenance.
