Brief Summary

Conservatism is considered the main concern in any treatment plan, the feather edge preparation design of laminate veneers have been introduced yet clinical studies are lacking to evaluate their clinical performance.The aim of this study is to evaluate the effect of the two different preparation designs on the functional and esthetic outcome of laminate veneers in terms of marginal adaptation, retention, fracture, marginal discoloration and patient satisfaction

Conditions

Dental Disorders Hard Tissues of Teeth; Tooth Discoloration

Keywords

Laminates; Vertical preparation; veneers

Outcome Measures
