Abstract

Abstract:

BACKGROUND: Studies have shown that because of the differences in tooth size, shape, texture, hardness and the others, the extracted teeth can cause some error to the experimental results. Computer aided design/computer aided manufacture (CAD/CAM) technology used to establish the standard test model can reduce the related experimental error.
OBJECTIVE: To establish the standard test model of maxillary central incisor with CAD/CAM technology, and to make the resin models of the extracted tooth, preparation and full crown by using the laser rapid prototyping technology in vitro.
METHODS: A complete maxillary incisor was selected, and the tooth surface was sprayed with the DPT-8 development solution. The three-dimensional models of the extracted teeth and preparation were completed with the Freedom scanning software, and the three-dimensional model of the full crown was finished through the model design. Resin models of the extracted teeth, preparation and full crown were made by using the Hyperdent software.
RESULTS AND CONCLUSION: The three-dimensional and resin models of the extracted teeth, preparation and full crown were successfully established in vitro, and had good geometric similarity. In laboratory studies, we can use CAD/CAM technology to obtain the standard test model of the extracted teeth with good geometric similarity, and reduce the experimental error.
