Much depends on where dental implants are placed and what they will be called upon to do. Small, skinny implants are less successful that longer, wider-diameter ones.  It is a matter of basic engineering support. Overall  health, quality of bone, oral hygiene, diabetes, smoking and the degree of functional stress placed on implant sites all play a role on implant longevity. Old age in a healthy individual is not a major deterrent to having implants.

The most favorable location for the placement of implants is in the front of the lower jaw where the bone density is greatest and the most supportive. In this area (the symphysis), dental implant success rates can be as high as 98-100%. In other areas of the mouth, success rates can drop off a bit.

According to current longevity studies, the success of contemporary implants in the front part of the upper jaw are anywhere from 90-95% after 10 years. Success rates for implants in the back of the upper and lower jaw are 85% – 95% after 10 years.  Success rates continue to improve as improvements are made in implant design and as knowledge and experience grows. Currently in my practice as in other experienced practices, success rates are climbing to better than 95% for almost all areas.
