Accuracy of Digital Models Using Open-access Software Programs

Trueness and Precision of Digital Models Obtained From Different Open-access Software Programs

Background: Despite the clear drive toward digital model transformation, there are limitations to some paid software necessary for digital model production. The aim of the study is to compare the accuracy of open-access software against paid software regarding the segmentation process to produce a digital model. Four groups of software programs will be assessed regarding their accuracy in the segmentation process to produce a digital dental model. The reference models will be scanned by a desktop scanner and will be set as the gold standard. The same models will be scanned by the same CBCT machine. The obtained DICOM data will be converted into STL files by four different software programs.

Inclusion Criteria:

• Complete records of patients (upper and lower).
• Intact models with complete anatomy.
• Complete permanent dentition

Exclusion Criteria:

• Broken or damaged stone models.
• Models of patients with orthodontic appliances or dental prosthesis
