Published clinical research shows that implant supported restorations have been successful for over 30 years with success rates now reaching over 95%. These cases were carefully followed from the very beginning and are likely to remain successful for the lifetime of these patients.
Dental implants are designed to be permanent but there are many factors that contribute to their longevity. Home care and regular visits to the dentist or specialist are probably the most critical aspects. However, smoking, grinding of the teeth, or too much pressure on the implants can alter their success.
By comparison, research shows that the typical tooth supported bridge lasts from 7-10 years and that partials and dentures last an average of only 5 years. In fact, insurance companies expect that bridges, partials, and dentures will last 5 years and will therefore pay for replacements every 5 years.
