Evaluating and comparing bony defects onn Human dry mandibles with cbct images and 3d Printed models – an in vitro study.

Abstract

ABSTRACT BACKGROUND: A cone beam computed tomography (CBCT) has proven to be an effective tool in dental diagnosis and treatment planning due to its accuracy and reliability. The 3D printing process creates objects one layer at a time by adding layers. A more accurate, customized, and effective approach to healthcare is provided by the combination of CBCT and 3D printing, which improves treatment results and patient satisfaction. AIM: To evaluate the accuracy of CBCT images and 3D-printed models acquired by CBCT imaging. MATERIALS AND METHODS: By using cylindrical burs, bilateral circumferential bone defects were created on 10 dry human mandibles on symphysis and parasymphysis regions. Later, CBCT scans were performed on dry mandibles. The scanned images were exported in DICOM format and then converted into STL files, which are used as a format for 3D printing. The measurements were done using the Sidexis tool on CBCT, using a digital vernier caliper on dry mandibles and 3D models, followed by a statistical analysis of the data.
