Accuracy of Digital Models Using 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.

Primary outcomes

  1. Deviation in digital models measurments

    Time frame: through study completion, up to 3 months

    3D deviation analysis will be done between the digital models of each participant and the reference model by reverse engineering 3-Matics software (Materialise NV, Belgium, Version 11.0). Each two STL models will be imported into the software. The mean deviation difference (measured in mm) will be calculated by 'Analyse' tool present in the software

Secondary outcomes

  1. Linear measurements

    Time frame: through study completion, up to 3 months

    Each digital model will be measured in the three dimensions:

    • Anteroposterior (the canine cusp tip to the mesiobuccal cusp tip of the first molar on the right side).
    • Transverse (inter-canine and inter-molar).
    • Vertical (the canine height, which is measured from the cusp tip to the gingival margin of the right canine by a line parallel to the long axis of the tooth).

  2. Teeth crown width

    Time frame: through study completion, up to 3 months

    For all teeth (twelve measurements for each arch), first molar to first molar, in both arches, the tooth measurements will include the mesiodistal widths from point contact to point contact.
