Proximal margin modifications for all-ceramic veneers

Conventional ceramic veneers circumvent contact areas and extend palatally in the gingival third of the tooth only. Veneers are no longer considered reversible therapy. With the objective of longevity in mind, proximal extensions beyond contact areas maximize the functional and aesthetic potential of veneers and maintain conservative tooth preparations. The clinical and laboratory advantages of proximal veneer extensions for anterior teeth significantly outweigh the disadvantage of increased tooth structure removal. This article presents a modified preparation technique for the proximal extension of ceramic veneer preparations in the anterior region.
