The preparation of the lamina in osteo-odonto-keratoprosthesis (OOKP) is complex and its longevity and water tightness important. Until now only acrylic bone cements have been used for bonding the optical cylinder into the dentin of the tooth. Our aim was to evaluate different dental adhesives for OOKP preparations.
Specimens of bovine teeth were produced by preparing 1.5 mm thick slices with holes of 3.5 mm in diameter in the dentin of the tooth. Every group (n=10 per group) was luted with a different adhesive: Classic Poly-(Methyl Methacrylat) bone cement, a universal resin cement and a glass ionomer cement. Every specimen of each group underwent force measurement completed with a uniaxial traction machine.
The highest mean force was measured for Poly-(Methyl Methacrylat) bone cement (128.2 N), followed by universal resin cement (127.9 N) with no statistically significant difference. Glass ionomer cement showed significant lower force values (78.1 N).
Excellent bond strength combined with the easy application was found for universal resin cement, which might become an alternative to acrylic bone cement in preparing an OOKP.
