Evaluation Of Cone Beam CT On Bone Mineral Density In Dental Implants

Objec ve:Quantitative measurement and analysis of bone mineral density in the planting area are made by using cone beam,providing reference for clinical safe and stable implant.Methods: To scan the 43 cases of quasi implant patients using KAVA dental cone beam CT of patients with missing teeth area,the scanning images by examvion software to reconstruct and 53 pre planting site of bone density were measured.The data were statistically analyzed by SPSS19.0 software,and the differences between bone mineral density and planting area were analyzed.Results: 1.The mandibular anterior teeth area average bone density value maximum(922.71 + 182.41)of Hu,followed by anterior teeth area(692.37 + 71.55)Hu,mandibular posterior area of 542.17 + 197.40 Hu,the maxillary posterior region bone mineral density value is the minimum(323.57 + 108.92)Hu,the.There was significant difference in bone mineral density(P < 0.05)in the area of missing teeth.Conclusion: All pre planting area,The mandibular anterior teeth area average bone density value is the highest,while the maxillary posterior region bone mineral density value is lowest.Cone beam CT can provide bone information,It is of great significance to the design of the plant before operation.
