Abstract
Introduction: Implant retained over-dentures are widely used for the rehabilitation of edentulous mandible to increase over-denture retention and stability. Implant stability can be measured by various non-invasive clinical test methods as resonance frequency analysis using Osstell. CBCT is widely used in dentistry specially in implant planning but without accurate information about bone density. However, with this increased usage of CBCT in dental field especially in implantology, the predictability of primary implant stability from CBCT image is of great value for oral implantologists.
Methodology: Twenty two completely edentulous patients were included in our study.
After performing the conventional steps of complete denture construction, the patients were imaged by CBCT using Planmeca ProMax® 3D Mid (Planmeca, Helsinki, Finland). A virtual implant was placed in the potential implant site in a position simulating the planned position of implant in the midline of mandible and the bone density in the potential implant site (inside) and 1mm around the implant (outside) was assessed. After implant installation, the primary stability was assessed using radiofrequency by the osstell device.
Results: There was non-statistically significant direct correlation between bone density (for both inside and 1mm surrounding the potential implant site) and primary implant stability.
Conclusion: Within the limitation of our study, no correlation was found between bone density measured from cone beam CT and primary stability measured by Osstell in elderly edentulous patients receiving single midline implant
