Summary
Trabecular bone volume and bone mineral density in the mandible are highly correlated. Quantitative computed tomography is a valid method for assessing mandibular bone prior to dental implant treatment.
Area of Science:
- Dental Implantology
- Oral and Maxillofacial Radiology
- Bone Densitometry
Background:
- Assessing bone quality is crucial for successful dental implant placement.
- Trabecular bone characteristics significantly influence implant stability.
- Quantitative methods are needed to accurately evaluate mandibular bone structure.
Purpose of the Study:
- To investigate the correlation between trabecular bone volume (TBV) and bone mineral density (BMD) in the mandible.
- To determine the reliability of TBV as an indicator of mandibular BMD.
Main Methods:
- Quantitative computed tomography (QCT) was used to measure BMD in 22 edentulous mandibular sections.
- Computer-based image analysis derived TBV from contact radiographs of nine autopsy-obtained mandibles.
Main Results:
- A significant positive correlation was observed between TBV and BMD in the mandible.
- Significant variations in TBV were noted both between and within individual mandibles.
Conclusions:
- The strong correlation validates TBV as a reliable indicator of mandibular BMD.
- QCT is a suitable imaging technique for pre-surgical assessment of bone quality before dental implant procedures.
