结局指标
主要结局
Implant stability
时间窗: 12 months
The implant stability was evaluated immediately postoperatively and after 3, 6, and 12 months. An Osstell Mentor device (Osstell, Savadaled, Sweden; Integration Diagnostics) was utilized to assess implant stability utilizing resonance frequency analysis (RFA). Measurements were made at 90° in four different directions in order to calculate the RFA value. The implant stability quotient (ISQ) was calculated by averaging the results for each implant.
