[Adhesion of artificial teeth to polymethacrylate resins].

UNLABELLED

In this study the microleakage is first tested between the poly-methylméthacrylate resins used in removable partial denture and the artificial teeth after storage in 100% humidity at 37 degrees C or after aging by an hydrothermal fatigue stress. Then the porcelain butt joint was improved by pyrolytic silanization.

MATERIALS

A metallic flask was realized, in this study, to polymerize strictly identical samples.

RESULTS

Due to polymerization in 100% humidity, the silane bond will be destroyed. Thermo-or chemopolymerizing resins are the only resins to allow the bonding with porcelain teeth by means of the sandwich technic.
