Density evaluation of pre-implant sites by dentascan software

Objectives: To measure the bone density in Hounsfield unit (HU) values at the sites of implant placement by Dentascans, and correlate it with respect to sex, individual jaws, side of the jaw, and zone in the jaw. Study Design: Twenty-five patients in the age group of 10 and 80 years, requiring implant placement, were selected for this study, using Siemens Somatom Sensation 64. The density was evaluated subjectively by the Dentascan software. Density of the bone at the implant sites was correlated with the sex of the patients, individual jaw, and zone in the jaw. Moreover, an independent 't' test was applied and the ' P ' value was determined at 95% confidence limits. Also the mean (minimum and maximum) density of the bone was evaluated according to the side of the jaw and an ANOVA test was applied followed by a Turkey test. Results: Based on the HU values, 75.40% values were in the D3 group, 16.39% in the D4 group, 4.95% in the D5 group, and 3.27% in the D2 group. In the D5 group, the lowest mean HU value was 124.5. Statistical analysis did not show any significant relationships. Conclusion: Bone density at the implant sites dictate the successful osseointegration of the implants. Dentascans provide a subjective evaluation of bone density at the implant sites.
