Objectives: To study the efficacy of pre-evaluation of implant sites by Dentascans. Materials and Methods: Twenty five patients between age groups of 15 -and 80 years requiring implant placement were selected for this study. The computed tomography (CT) scan machine used for this study was Siemens Somatom Sensation 64. This has multidetector technology with 32 detector array and 64 data channels. Dental software used was Syngo Dental CT 2006 A-W VB20B-W. Axial, paraxial and panoramic images obtained were evaluated for available ridge height and width at implant sites, proximity to maxillary sinus and inferior alveolar canal, easy identification of inferior alveolar canal, radiographic presence of bony concavities and density at implant sites. Results: Dentascan was an effective software in pre-evaluation of available height and width at the implant sites. There was a co-relation between the available bone at the implant sites and region of jaw, sex and age of patients. Proximity to maxillary sinus and inferior alveolar canal was clearly demonstrated by Dentascans. Inferior alveolar canal was identified in 85.71% cases. Bony concavities were identified in 22.95% cases. Dentascans provide subjective evaluation of bone density in Hounsfield units (symbol HU). Conclusion: Dentascans are a rapid, time saving, effective, safe and indispensable procedure in dental implantology. Dentascans determines the available bone at the implant sites accurately without any magnification or distortion that is observed in panoramic radiography. Osseous morphology variations like knife edge ridges, which cannot be demonstrated on conventional radiography, could be appreciated on Dentascans. Bony concavities may not be observed on panoramic radiography; Dentascans provide the opportunity to appreciate such details. Critical anatomical landmarks can be clearly demonstrated on Dentascans. Dentascans provide a subjective evaluation of the density at the implant site.
