Comparison and Assessment of Multi-Detector Row CT and Cone Beam CT in Hounsfield Unit for Bone Density Evaluation in Implant Placement Parts

Brief Background Rehabilitation of edentulous posterior atrophic maxilla has always been an exigent task in the field Implantology. Studies have shown, the use of Choukron’s platelet rich fibrin as a sole grafting material in sinus floor and immediate implant placement leading to bone formation in the peri-implant region. Purpose of the Study This study was conducted as novel research where, Direct Sinus Membrane elevation and simultaneous Implant placement without any bone graft resulted in bone formation in sub-antral space. This study compares and evaluates the bone formation with the help of Cone Beam CT Scan (CBCT) in sub-antral space following direct sinus membrane elevation and simultaneous implant placement and platelet rich fibrin as the sole graft. Materials and Methods 48 patients who fulfill the inclusion criteria were divided as Group I- direct sinus membrane elevation and implant placement without any graft and Group II- direct sinus membrane elevation and implant placement along with PRF as sole graft Results and Analysis Unpaired‘t test’ was used where, we ‘p’ value was compared with the level of significance. On comparing the peri-implant bone density in Hounsefield units, in CBCT scans; the bone density was more in group II which was statistically significant (p<0.05). Summary and Conclusions PRF has proved to be a valuable autologous augmenting material in direct sinus membrane elevation and simultaneous implant placement in edentulous posterior maxilla. Key Words Hounsefield Units, Sub-antral space, Peri-implant, Cone Beam CT Scan.

Objective: To assess jawbone density in terms of Hounsfield units using cone beam computed tomography fordental 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 wereincluded in the study. After ethical approval, informed and written consent, brief history was taken and a singleradiographer exposed and took cone beam computed tomography scan of all the subjects using PLANMECAmachine. A single investigator using PLANMECA software recorded jawbone density in terms of Hounsfieldunits. All data were presented as mean, SD and one way ANOVA was used. Multiple comparisons of the fourregions in the maxilla and mandible were performed with a Tukey test. An independent t-test was also used tocompare 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 maxilla 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...........
