Design outcomes

Primary

Measure	Time frame	Description
Implant stability	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.
