Assessments of Jaw Bone Density at Implant Sites Using CBCT
摘要
Abstract
Objective:To assess the bone density of dental implant sites using CBCT and Simplant software, and establish a quantitative ranges for each bone quality classification according to Lekholm and Zarb grouping. Methods: 109 patients’ jaw bone were scanned by CBCT, the images were reconstructed by the Simplant software. The bone density of 195 potential implant sites was measured and the results were recorded using Hounsfield units (HU). The data was analyzed with SPSS 19.0 software package for Mann-Whitney U test. Results:The mean bone density in all implant sites was (369.15±181.60) HU. The rank of mean bone density was anterior mandible [(699.41±138.76) HU]>anterior maxilla [(463.96 ±145.93) HU]>posterior mandible [(400.66 ±123.32) HU]>posterior maxilla [(236.19 ±150.85) HU]. Quantitative parameters ranged as follows: bone quality of D4 was less than 200 HU, bone quality of D2/3 was 200 to 600 HU, and bone quality of D1 was above 600 HU. Conclusion: Anterior region of mandible has the highest mean bone density and posterior region of maxilla has the lowest mean bone density. It is therefore proposed that an objective classification which confirms the importance of a site-specific bone tissue evaluation prior to implant installation.关键词
