Direction estimation on 3D-tomography images of jawbones

Abstract: The present work expose a technique of estimation of optimal direction for placing dental implant. A volumetric computed tomography (CT) scan is used as a help of the following searches. The work offers criteria of the optimal implant placement direction and methods of evaluation on direction’s significance. The technique utilizes structure tensor to find a normal to the jawbone surface. Direction of that normal is then used as initial direction for search of optimal direction. The technique described in the present work aimed to support doctor’s decisions during dental implantation treatment.
