The use of stereolithography as a diagnostic tool in implantology
Keywords:
Dental implantation endosseous, TrendsAbstract
This article reports on the use of Stereolithography, a Rapid Prototyping Technique, for constructing 3D models of patients subjected to prosthetic rehabilitation through implant-supported prostheses. Epoxy resin 3D models were crafted through a CAD/CAM system (from images obtained by computed tomography) to be used for treatment planning and the construction of metallic individualized surgical guides. A 40-year old patient, totally edentulous on the maxilla, was subjected to placement of 8 implants positioned according to the subperiostal surgical guide crafted on the stereolithography models. Thanks to the precision of this surgical guide, implants were inserted in the planned positions, and the surgical time was greatly reduced. After implant insertion, the patient received a fixed, complete prosthesis of the protocol type.
