This depends very much on where the implants are placed and what they will be called upon to do. The best case scenario is the placement of implants in the front portion of the lower jaw. Here success can be as high as 98-100%. In other areas of the mouth, success rates can drop significantly. According to figures that we have today, the success of implants in the front part of the upper jaw are anywhere from 90-95%. Success rates of implants in the back part of the upper and lower jaw can be in the 85-95% range. The success rate in my practice for the past ten years has been 99+% for all implants placed.
