Digital technologies to facilitate minimally invasive rehabilitation of a severely worn dentition: A dental technique.

This technique report describes digital technologies to facilitate minimally invasive rehabilitation with computer-aided design and computer-aided manufacturing (CAD-CAM) veneers for a severely worn dentition. The lingual veneers without tooth preparation and occlusal veneers with minimal tooth preparation were designed from the digital scan of the interim restorations. To facilitate the cementation of multiunit lingual veneers on unprepared teeth, a custom 3D-printed guide was designed from the digital cast of the natural dentition with the lingual veneers. The guide reduced the technique sensitivity of freehand practice and allowed the verification of the complete seating of multiunit lingual veneers on unprepared teeth. The digital technique provided a valid and reliable approach to making and cementing multiple CAD-CAM veneers for the minimally invasive restoration of worn teeth.
