3D-printed tooth reduction guide for minimally invasive veneer preparations. A case report.

Current CAD/CAM techniques allow clinicians to design and 3D print tooth reduction guides that facilitate controlled preparations in the esthetic zone. The present case report describes the workflow for designing and printing a tooth reduction guide intended to assist ceramic veneer preparations. This 3D-printed guide divides the facial surface of the teeth into four areas and allows the measuring of all areas, including the incisal edge, with a periodontal probe. Using this 3D-printed appliance can simplify and expedite tooth preparation for ceramic veneers and reduce the risk of excessive tooth reduction.
