Summary
Dental implant stability is strongly linked to jawbone density and location. Higher bone density, measured in Hounsfield units (Hu), correlates with better primary implant stability, assessed by resonance frequency analysis (ISQ).
Area of Science:
- Dental Implantology
- Oral Surgery
- Biomaterials Science
Background:
- Assessing primary dental implant stability is crucial for successful osseointegration.
- Bone density is a key factor influencing implant stability, but its precise relationship with quantitative measurements requires further elucidation.
Purpose of the Study:
- To correlate bone density (Hounsfield units) with primary implant stability.
- To investigate the relationship between insertion torque (Ncm) and resonance frequency analysis (ISQ) values and bone density.
Main Methods:
- Utilized computerized tomography (CT) scans for preoperative bone density evaluation in 10 patients (54 implant sites).
- Determined mean bone density using Physioplanet TM software.
- Recorded bone quality via drilling resistance, insertion torque, and resonance frequency measurements.
Main Results:
- A statistically significant relationship was found between bone quality density, implant location, and ISQ values.
- Bone density measured in Hounsfield units (Hu) showed a correlation with the Lekholm & Zarb bone quality classification.
Conclusions:
- Computerized tomography-derived bone density and implant location in the maxillaries are strongly related.
- Primary implant stability, measured by resonance frequency analysis, is dependent on bone density, bone quality, and implant location.
