The aim of this study was to measure implant stability quotient (ISQ) values in grafted sites during 5 years of follow-up. Sixteen patients received a total of 36 implants inserted in sites treated with autologous bone (group A) or porcine bone in addition to autologous bone (group B). In both groups, resonance frequency analysis (RFA) values increased during the observation period. At 2 months, statistical analysis showed significantly lower ISQ values for group B than for group A (P = .0134) and significantly higher ISQ values in the mandible than in the maxilla (P = .0251). RFA measurements suggested stable long-term results for implants inserted in both groups.
