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.
本研究的目的是在5年的随访期间测量移植部位的种植体稳定性商数（ISQ）值。16名患者共接受了36颗种植体，这些种植体植入了接受自体骨治疗的部位（A组）或除自体骨外还接受猪骨治疗的部位（B组）。在两组中，观察期内共振频率分析（RFA）值均有所增加。在2个月时，统计分析显示B组的ISQ值显著低于A组（P = 0.0134），且下颌骨的ISQ值显著高于上颌骨（P = 0.0251）。RFA测量表明两组植入的种植体均取得了稳定的长期效果。
