Feasibility and Accuracy of Digitizing Edentulous Maxillectomy Defects: A Comparative Study.

Abstract

PURPOSE:

The aim of this study was to evaluate the feasibility and accuracy of using an intraoral scanner to digitize edentulous maxillectomy defects.

MATERIALS AND METHODS:

A total of 20 maxillectomy models with two defect types were digitized using cone beam computed tomography. Conventional and digital impressions were made using silicone impression material and a laboratory optical scanner as well as a chairside intraoral scanner. The 3D datasets were analyzed using 3D evaluation software.

RESULTS:

Two-way analysis of variance revealed no interaction between defect types and impression methods, and the accuracy of the impression methods was significantly different (P = .0374).

CONCLUSION:

Digitizing edentulous maxillectomy defect models using a chairside intraoral scanner appears to be feasible and accurate.
