Abstract

|
|
The purposes of this study were to evaluate the accuracy of orthodontic model fabricated by dental digital equipments(intra oral scanner and 3D printer). A master model with the prepared upper full arch tooth was used. Ten same case of stone orthodontic models were manufactured(gold standard group), and 3D printing models were made from intra oral scanner and dental 3D printer experimental group). The four linear distances(inter-canine distance, inter-molar distance, right dental arch length and left dental arch length) between the four reference points(cusp of right canine, cusp of left canine, mesio-buccal cusp of right first molar and cusp of left first molar) were measured digital vernier calipers. The independent t-test were used(α = 0.05) for statistical analysis. Although gold standard group showed larger than experimental group in all distances. non exceeded the clinical acceptable range.
