Veneer computer aided design based on reverse engineering technology / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the computer aided design (CAD) method of veneer restoration, and to assess if the solution can help prosthesis meet morphology esthetics standard.</p><p><b>METHODS</b>A volunteer's upper right central incisor needed to be restored with veneer. Super hard stone models of patient's dentition (before and after tooth preparation) were scanned with the three-dimensional laser scanner. The veneer margin was designed as butt-to-butt type. The veneer was constructed using reverse engineering (RE) software.</p><p><b>RESULTS</b>The technique guideline of veneers CAD was explore based on RE software, and the veneers was smooth, continuous and symmetrical, which met esthetics construction needs.</p><p><b>CONCLUSIONS</b>It was a feasible method to reconstruct veneer restoration based on RE technology.</p>
