Application MDP (10-Methacryloyloxydecyl dihydrogen phosphate) convinces users by its special monomer structure: This phosphate monomer was extremely effective for enamel, dentin and on metal alloys. Consequently, the material including the MDP monomer, was introduced as a high-performance adhesive resin cement for the cementation to tooth structure and to metals. The impressive success of encouraged many manufacturers to integrate the MDP monomer into other bonding systems as well as to obtain a high degree of adhesion to tooth substrate from the formation of a chemical bonding. MDP is now present in SE Bond, S3 Bond, Protect Bond, Teethmate, Alloy Primer, Ceramic Primer, Porcelain Repair System. Moreover, it remains possible that long-term protection has been provided in the form of the MDPB monomer. It is expected that the product prevents the absorption of bacteria by a change in the surface structure, contributing in the long run to protection from secondary caries. The bonding layer releases small quantities of fluoride to strengthen the neighboring tooth hard structure. A special copolymer aids in preventing shrinkage of the bonding layer and the consequent negative effects on the bond strength.
