Assessment of Dental Arch Reproduction Quality by Using Traditional and Digital Methods

Background: There exists few scientific reports on the quality of digitally reproduced dental arches, even though digital devices have been used in dentistry for many years. This study assesses accuracy standard arch model reproduction using both traditional and methods. Methods: The full upper by physical models obtained through methods was compared: gypsum (SGM) printed from data an intraoral scanner (TPM) (n = 20). All were scanned with a reference scanner. Comparisons made Geomagic Control X program measuring deviations relative to analyzing linear dimensions deviations. Results: average error ranged 0.0424 ± 0.0102 millimeters (mm) 0.1059 0.0041 mm (TPM). In methods, all analyzed shortened statistically significantly degree compared traditional. SGM method provided smallest significant pattern, TPM largest. intercanine dimension lowest accuracy, intermolar highest each method. Conclusions: Traditional trueness dimensions. method, where
