- Abstract
Background: Digitization of information is entering more and more branches of dental medicine. Modern methods of working with CAD/CAM cutting of structures or 3D printing require them to use only digital information about the objects. It can be obtained by scanning directly into the patient's mouth via an intraoral scanner, or by scanning an impression from a prosthetic field or model using an intra or extraoral scanner. Purpose: To compare the dimensions of a real phantom model with the values obtained from its scan with 3Shape intraoral scanner. Material and methods: The study was performed on 10 phantom models of Frasaco Dental Model A-3 with partial edentulism. The first upper right molar 16 was measured three times at four points - mesio-distally in the cervical and equator zone, and vestibulo-lingually in the cervical and equator zone. The same model was scanned using an intraoral 3Shape scanner. The results were statistically processed by ANOVA test and multiple comparison analysis test (Scheffee). A significance level of the zero hypothesis was assumed to be p <0.05. Result: A statistically significant difference was found only in the size of the vestibulo-lingually equator area of the model and the vestibulo-lingually equator zone of the software (P = 0.000). Conclusion: The scanning accuracy obtained is highly consistent with the actual size of the object.
