Abstract

Aim: The purpose of this study is to evaluate Bone Mineral Density (BMD) by Hounsfield Units (HU) and Trabecular Bone microstructure by Fractal Dimension (FD) around dental implants pre-operatively and post operatively by CBCT. Materials and Methods: Twelve patients with partially edentulous sites of age group between 20 to 50 years with good systemic health were enrolled. Patients are assessed for BMD before (baseline) and after placement of implants (9 months) using analysis by Hounsfield Units (HU) and FractalDimension (FD). Results: BMD by HU improved from baseline (412.25 ± 105.16) to 9 months (626.58 ± 114). Trabecular Bone Microstructure by FD improved from baseline (0.78 ± 0.06) to 9 months (1.40 ± 0.05). Unpaired t test and paired t test were performed for inter groupand intra group analyses respectively. Conclusion: Present study was undertaken to evaluate bone changes on implants placed in the suitable edentulous sites. All the implant Osseo integrated without any uneventful healing. The marginal bone loss found was also minimal and found to be statistically non-significant. With the limited sample size it can conclude that fractal analysis holds good for bone architectural analysis.
