| Abstract | ||
| For accurate treatment planning, virtual surgical planning makes use of clinical data, image testing, plaster models of dental arches, and clinical pictures. Plaster model scanning can be done in two ways: using an extraoral scanner or cone-beam computed tomography (CBCT).The aim of this study was to assess the accuracy digital dental stone models obtained using cone beam computed tomography and extraoral scanner. Materials and methods: The control group was the measurement performed on 20 plaster models by digital caliper. The same 20 models were scanned through extraoral scanner and CBCT in order to compare the dimensional accuracy. Six measurements were performed on each model between reference points. Results: There was no statistically significant difference in dimensional accuracy between digital models obtained by CBCT scanning and extraoral scanning compared with digital caliber measurements with higher accuracy for extraoral scanned models. Conclusion: CBCT and extraoral scanning digitized models have acceptable dimentional accuracy. | ||
