ABSTRACT
In view of the instance of a damaged medial incisor, we have introduced a method using computer aided technology to design and manufacture the laminate veneer. Firstly, the data on preparation teeth was retrieved by the 3D-optical measuring system. Secondly, the triangle mesh model of preparation teeth was reconstructed by using the reversion project software. And the 3D model of the laminate veneer was constructed through some operations, such as extracting the edge line of preparation teeth, mirroring the integrity incisor and local freeform transform. The result has proved that the fabrication process is reliable and efficient. The dental restoration quality is steady and precise. The artifical laminate veneer has met the request of esthetical symmetry.
