Automatic analysis algorithm for acquiring standard dental and mandibular shape data using cone-beam computed tomography

Abstract This study aims to introduce a new algorithm developed using retrospective cone-beam computed tomography (CBCT) data to obtain a standard dental and mandibular arch shape automatically for an optimal panoramic focal trough. A custom-made program was developed to analyze each arch shape of r...
