The preparation also included reducing the incisal edge by 1-2mm finishing down 2mm on the lingual surface and interproximally. An impression was taken, shade selected and a provisional fabricated. Provisionalization after preparation for porcelain veneers is optional. Placement of composite, without etching or application of a bonding agent, can be quick and easily pops off before placement of the final restoration. To ensure that the composite will not bond to the preparation, a light coat of Vaseline can be applied to the preps and adjacent tooth structure.
Details can dramatically enhance the final result of an aesthetic case.
The lab was instructed to fabricate veneers. A picture will serve as the best aid to the dental technician in helping them create the illusion of reality. With this in mind, the technician was asked to place areas of hypocalcification at the incisal edge of the veneers. Image 14 Placement of the veneers was accomplished using a light activated composite bonding system. A critical factor in achieving a good bond between veneer and tooth is the use of a silane coupling agent.
