[Esthetic vestibular restorations using composite materials with the direct bonding technique. Interim clinical...

503 clinical controls of esthetic restorations made by the direct technique with composites were evaluated. Records were made of the type of restoration according to the nature of the surface receiving the bonded veneers. Also marginal breakdown chipping, fractures, discoloration, loss of glass etc were registered. Correlations were made with the age of the restorations, and with personal records as hygiene level, age, sex, smoking habits etc. Nearly 10% of the controls involved a correction or replacement of the veneer. Nearly 90% of the veneers needed repolishing but more than 90% of the patients stayed satisfied with the esthetic solution offered. The results were much worse in the poor hygiene and smoking groups.
