[Clinical morphology of bond zone in bonding agent composite systems]

Three composites--Colténe DRS, P-10, Silux--and their bonding agents (enamel bond systems, Scotchbond) have been investigated. To this purpose the usual examination of "margin close" according to Lutz in 1977 was modified in "morphology of bond zone" (bm). After one year the phosphonated bonding agents has shown better results dependent on composites than enamel bond systems. A year later the "bons zoné's morphology" of various composites did not differ from another because P-10 underlied a heavy occlusal wear. In spite of that the phosphonated bond to enamel has proven better results than to dentin. Replication technique was applied in some chosen cases with clinical acceptable bond zones.
