Combination of minimal- and non-preparation techniques with ceramic veneers for managing esthetic deficiencies

Non-preparation (non-prep) ceramic veneers are a convenient and conservative treatment option, but controversy exists about their predictability. Concerns remain about possible overcontouring, poor-quality margins, and early esthetic failure. The present clinical report describes the combination of minimally invasive and non-prep ceramic laminate veneers in the esthetic zone with a 6-year follow-up to replace stained composite resin veneers on both maxillary central incisors. Composite resin veneers on the maxillary central incisors were replaced with ceramic veneers, and a non-prep ceramic veneer was placed on the maxillary right lateral incisor. A diagnostic additive wax-up was done, followed by a mock-up guide to conservatively prepare both maxillary central incisors. The three feldspathic porcelain veneer restorations were cemented under rubber dam isolation. The 6-year follow-up showed that stained composite resin veneers can successfully be replaced with minimally invasive and non-prep ceramic veneers to meet the patient's esthetic wishes. Overall, well-planned and well-executed restorative procedures combining minimal preparation and non-prep for ceramic laminate veneers can achieve esthetically pleasing outcomes and maximize tooth structure preservation in the maxillary anterior region.
