The plastic-based dental restorations previously mentioned in the prior art have defects, such as. B. rapid decrease in adhesion to the tooth base or lack of a self-etching property. DOLLAR A dental materials containing phosphonic acids of the general formula I DOLLAR F1 in which DOLLAR AR · 1 · = H, methyl and DOLLAR A n is an integer between 2 and 11, DOLLAR A and in particular bonds as dental materials have the ability to form a strong and permanent bond of the dental material to form the tooth base. In addition, they allow the dental material to be introduced into the cavity in one step, since the self-etching property means that prior etching of the tooth base is unnecessary. |
