Long-term clinical and radiographic outcomes of 750 dental implants: A 10-year follow-up study on peri-implant health along with factors influencing success in 500 patients

Abstract

Dental implants show favorable short-term outcomes, but evidence regarding their long-term survival and determinants of clinical success remains limited. Therefore, it is of interest to evaluate the 10-year clinical and radiographic outcomes of 750 dental implants placed in 500 patients, including implant survival, peri-implant health and marginal bone loss. After 10 years, the cumulative implant survival rate was 97.6% (732 implants), mean marginal bone loss was 1.1 +/- 0.4 millimeters and peri-implantitis was diagnosed in 6.2% of surviving implants. A history of periodontitis (Odds Ratio = 2.5; p < 0.001) and smoking (Odds Ratio = 1.9; p < 0.01) were the strongest predictors of increased marginal bone loss and implant failure. Thus, data provide robust long-term evidence supporting the durability of dental implants while identifying key patient-related risk factors that can guide individualized treatment planning and maintenance strategies.
