Present day implants have shown a high success rate (80 to 95% over 15 years) in patients with healthy mouths. The success rates of dental implants in patients who are susceptible to gum disease is slightly lower (80 to 85% over 7 years). Over 90% of implants will bond successfully to the jaw bone.As an implant patient you need to be in good general health. Some chronic diseases, such as diabetes, osteoporosis or chronic sinus problems could interfere with healing and make your implants more likely to fail. Smoking may well shorten the life of an implant. Make sure you to tell your dentist about any medications you take regularly.Any associated restorations (crowns, bridges or dentures) will need maintenance in the same way as conventional restorations.If your implant is unsuccessful, your bone should grow back in about 3 months or so.
