Clinical evaluation of restored maxillary incisors: veneers vs. PFM crowns

This cross-sectional study compared the periodontal health and clinical acceptability of maxillary incisors restored with porcelain veneers vs. porcelain-fused-to-metal crowns. The authors evaluated 60 patients, a total of 120 restorations, in groups according to the age of the restorations (zero to 60 months). Margins of veneers were generally more supragingival with less gingival inflammation. All veneers were clinically acceptable, while 5 percent of PFMs failed because of secondary caries.
