Guided access cavity preparation using cone-beam computed tomography and optical surface scans - an ex vivo study.

Abstract

AIM To evaluate ex vivo, the accuracy of a preparation procedure planned for teeth with pulp canal obliteration (PCO) using a guide rail concept based on a cone-beam computed tomography (CBCT) scan merged with an optical surface scan. METHODOLOGY A total of 48 teeth were mounted in acrylic blocks. An apical canal preparation was created to simulate… (More)
