The aim of this study was to estimate the relationship between jaw bone density and total bone density.
The subjects used were patients who desired implant treatment and who were inspected through pre-operative CT examinations. The number of patients was 19. In the maxilla, bone mineral density (BMD) was measured at the cancellous bone between the nasal cavity and the maxillary sinus. In the mandible, BMD was measured at the cancellous bone beneath the mental foramen.The CT numbers were corrected by the QCT method. The bone mineral content of the total body was obtained byΣGS/D through microdensitometry and OSI (Osteo Sono-assessment Index) through QUS(Quantitative Ultrasound).
The following results were obtained.
1. BMD (total of maxilla and mandible) was significantly correlated with OSI.
2. BMD (total of maxilla and mandible) was significantly correlated withΣGS/D.
3. OSI was significantly correlated withΣGS/D.
From the above results, it was concluded that jaw bone density reflected the changes of the total bone density.
