【 摘 要 】

Objective: To assess jawbone density in terms of Hounsfield units using cone beam computed tomography for dental implant treatment planning in patients reporting to a local tertiary care dental hospital Study Design: Cross sectional study. Place and Duration of Study: Department of Periodontology and Oral Implantology, Fatima Memorial Hospital, Lahore, from Mar to Sep 2018. Methodology: A total of 100 patients who fulfilled the inclusion criteria and underwent implant placement were included in the study. After ethical approval, informed and written consent, brief history was taken and a single radiographer exposed and took cone beam computed tomography scan of all the subjects using PLANMECA machine. A single investigator using PLANMECA software recorded jawbone density in terms of Hounsfield units. All data were presented as mean, SD and one way ANOVA was used. Multiple comparisons of the four regions in the maxilla and mandible were performed with a Tukey test. An independent t-test was also used to compare gender with age groups and bone density. Results: Total of 100 patients who underwent implant placement were included, 48 (48%) were males & 52 (52%) were females with the mean age of 28.53 ± 5.33 years. The mean jawbone density in terms of Hounsfield units using cone beam computed tomography in anterior maxilla was 709.75 ± 122.63 Hounsfield units, posterior maxi-lla was 299.66 ± 73.09 Hounsfield units, anterior mandible was 1093.34 ± 109.42 Hounsfield units and posterior mandible was 599.45 ± 135.55 Hounsfield units (p<.001). Conclusion: The anterior mandible and anterior maxilla has the maximum mean bone density value for the jaw followed by the posterior mandible and the minimum mean bone density value for the posterior maxilla.
