Porcelain laminate veneers are a conservative treatment to enhance esthetics, tooth shape, color, and contours. Enamel preservation during tooth preparation is essential for the long-term success of these micromechanically retained partial coverage restorations. Different methods have been described to clinically assess tooth preparation relative to definitive restorative contours. This clinical report describes a digital workflow to fabricate 3-dimensionally (3D) printed tooth reduction guides based on digital esthetic planning. These 3D-printed reduction guides help clinicians visualize and gauge tooth preparations relative to the desired restorative contours, aid in enamel preservation, and overcome some of the limitations associated with conventionally fabricated tooth reduction guides.

Section snippetsClinical report

A 27-year-old woman with a noncontributory medical history presented with the chief complaint of unsatisfactory dental esthetics. The intraoral examination revealed bilateral diastemas between the maxillary lateral incisors and canines and between the right maxillary canine and first premolars (Fig. 1). Her periodontium was healthy without clinical attachment loss, and she had a mutually protected occlusion. Treatment options, including orthodontic treatment and esthetic crown lengthening to

Discussion

PLVs, requiring 4.3 times less tooth structure removal, present a conservative alternative to complete coverage crowns.6 When compared with indirect composite resin veneers, PLVs have been reported to have better long-term survival and prognosis.5 An alternative treatment would be direct composite resin veneer restorations. Although direct composite veneers can be performed in a single visit without significant enamel reduction, they present some drawbacks, including the lack of long-term color

Summary

This clinical report described a fully digital workflow for the fabrication of a 3D-printed veneer reduction guide based on digital virtual diagnostic waxing. These reduction guides can help clinicians visualize tooth preparations relative to the designed restoration contours, preserve enamel, and overcome some of the limitations associated with conventional reduction guides.
