Feasibility of Assessing Maxillary and Mandibular Bone Mineral Density for Dental Implantation by Using Multidetector Computed Tomography

초록

Purpose: The purpose of this study was to evaluate the feasibility of measuring bone mineral density (BMD) of the maxillary and mandibular bones for dental implantation by using multidetector computed tomography (MDCT). Materials and Methods: We performed MDCT in 141 patients (78 women and 63 men) at the lumbar vertebrae and at the maxillary and mandibular bones, with a view to dental implantation, from July 2015 to June 2017. Quantitative CT (QCT) using MDCT was performed to obtain Hounsfield unit (HU) values for the maxillary and mandibular bones and to obtain T scores for the lumbar vertebrae. We statistically analyzed the relationships among HU values, and the correlations of QCT values with T scores and of T scores with HU values. Results: There were statistically significant correlations among all these parameters. Conclusions: QCT using MDCT of the maxillary and mandibular bones seems to be a feasible method for measuring BMD before dental implantation.
