Novel Technique for Creation of Guide Grooves When Preparing Teeth for Ceramic Veneers.

OBJECTIVE: Consistent thickness and ideal form are important considerations for treatment with ceramic veneers, however conventional preparation technique allows for the risk of certain shortcomings relative to these factors. This article introduces a preparation method that creates superior abutments. CLINICAL CONSIDERATIONS: When preparing abutment teeth for ceramic veneers, it is desirable to remove as little tooth substrate as possible, both to preserve an enamel surface and respect minimally invasive principles. However, traditional veneer preparation techniques often make it difficult to achieve ideal form with a veneer of suitable thickness. CONCLUSION: Creating proper guide grooves on a tooth's line angles permits the reliable creation of an ideal abutment form while removing only minimal amounts of tooth substrate. CLINICAL RELEVANCE: This technique is aimed at improving the form of the abutment tooth.
