Facts And Figures
At this time, only 2% of patients worldwide who are replacing missing teeth are opting for dental implants, but the number has been growing steadily over the past several years at a rate of 12-15%.1
By age 50, Americans have lost an average of 12.1 teeth (including wisdom teeth). 2
The overall U.S. rate of full edentulism (loss of all permanent teeth) for adults 18 and older is approximately 10%, and the rate increases with age (approximately 33% of those 65 and older are completely edentulous in the U.S.) 3
A five-year multicenter study in progress at four private practices to determine the cumulative success rate and prosthetic outcome when using 3is Osseotite implants in the posterior maxillary and mandibular areas (with a total of 219 implants placed in 74 patients) yielded the following findings after 34.4 months:
- The cumulative success rate (those that initially osseointegrated) for all 219 implants at 34.4 months was 98.6%. Note: Of the 219, 3 failed before integration
- The cumulative implant success rate for anterior implants was 100%
- The cumulative implant success rate for posterior implants was 98.4%
- The cumulative postloading (after crown or prosthesis attached) success rate for both anterior and posterior implants was 100% 4
Our office has achieved a similar cumulative success rate over the past 5 years and our experience supports the findings of this study.
