Primary Stability in D3 Synthetic Bone of Different Implant Macrogeometries

Objectives: The aim of this research was to study, the primary implant stability on polyurethane foam sheets, wide-threaded design of implant compared to narrow-threaded implant.
Methods: Two implant designs (FMD,Rome, Italy)were positioned on polyurethane block in vitro: The wide-threaded implant, and the narrow-threaded implant. Moreover, for each group two size were considered: 3.8mm x 12mm and 4.8mm x 12 mm. The insertion torque (IT) values, the removal strength (RT), and the Periotest analysis were evaluate.
Results: A significant higher IT and RT was recorded for wide-threaded implant (p<0.01) if compared to narrow-threaded implant. A higher stability of wide-threaded implant was evidenced by Periotest measurements (p<0.01).
Conclusions: The wide-threaded implant design showed a higher primary stability on alveolar cancellous synthetic bone in vitro and are suggested for a clinical application in poor density bone ridge.
