Dentinal enamel adhesive for composite materials in dentistry. valuation to axial traction

摘要

Evolution of composite materials and in particular of dentinal enamel adhesive systems in the last years have achieved inimaginable objectives. Infact today it's possible withthese materials to reform perfactly on or several dental parts destroyed that will sustain with facility the chewing loods of oral cavity. Therefore, we have proposed like principal bjective the study of a strenght that develop in the complex biomecanic system of chewing like the axial traction. Test has been effected following the specified method by (I. Crivelli Visconti; E. Cornetta; C. Valentino; C. Riccio 1997) with the aim to value the agree of bond of four adhesive systems of last generation. Adapting system and fixing expectations have satisfied questions, considering that now there aren't specifications for these tests. Infact both ISO (International Organization Standard) and FDI (Federal Dental International) haven't produced regular operative standards scientifly reproducing.
