Primary Stability of Two Different Macro Design of Implants Placed on Pterygoid Bone: A Fresh Frozen Cadaveric Study

We aimed to evaluate the primary stability of pterygoid implants as comparing two different implant design in fresh frozen human cadavers using the resonance frequency analysis (RFA) method. Tapered and parallel implant types (NobelActive® and NobelParallel™, Nobel Biocare, Gothenburg, Sweden) were placed on the right and left sides of maxilla of 10 fresh human cadavers. Using Osstell® Mentor III and SmartPegs (Integration Diagnostics, Göteborg, Sweden), the resonance frequency measurements were made immediately after the implant placement. The two different macro-design types of implants were compared in terms of ISQ values, it was observed that there was no statistically significant difference between each macro designs. In conclusion, our study showed that the pterygoid implant was ideal for biomechanical stability scenario in managing the edentuluos solutions of posterior maxilla with dental implants.
