Clinical Evaluation of Dentacolor as a Posterior Veneering Agent

A growing number of clinicians have been using laboratory light-cured resins as a substitute for porcelain veneers. These new systems offer a number of advantages over porcelain. In addition to possessing the ability of being repaired or modified directly in the oral cavity, they can be used with virtually any alloy. This two-year study dealt with the clinical evaluation of Dentacolor as a veneering agent on posterior crowns. Forty restorations were inserted into a series of patients and evaluated for the following characteristics: color matching ability, wear or loss of anatomic form, surface texture and microleakage at the veneer-metal interface. At the end of the two years the average wear was only 22 μm. Furthermore, the wear rate was linear. The surfaces were free from pitting, retained a high luster, and exhibited excellent color matching ability.
