ADHESIVE MONOMERS TO DENTAL CERAMICS .3. INFLUENCE OF SURFACE-TREATMENT ON EFFECTIVE ADHESION OF CALCIUM METAPHOSPHATE CERAMIC WITH N-(VINYLBENZYL)IMINODIACETIC ACID

Influence of surface treatment of calcium metaphosphate ceramic was an alyzed in detail to achieve high adhesion in an aqueous environment wi th N-(vinylbenzyl) iminodiacetic acid as a novel dental adhesive monom er. The adhesion strength was enhanced greatly by alkali etching of th e ceramic surface, although the adhesion profile varied with etching c onditions. Scanning electron microscopy, electron probe microanalysis, and roughness evaluation indicated that high adhesion was closely ass ociated with the formation of fine irregularity on the surface that wa s rich in Ca. N-(Vinylbenzyl)iminodiacetic acid was thus confirmed to be a suitable adhesive monomer for the ceramic in dentistry in terms o f strength and durability when the ceramic surface was properly etched .
