15 Years of Evidence for the Bonding Effectiveness of MDP to Zirconia Ceramics

How did experts think about the effectiveness of MDP through the years? You can read about it below.

“In particular, primers and composite cements that contain 10-methacryloyloxy-decyl-dihydrogen-phosphate (10-MDP) resulted in a relatively high bond strength and durability.”

N. Nagaoka et al: “Chemical interaction mechanism of 10-MDP with zirconia” Nature, Sci Rep. 2017; 7: 45563.

“For most zirconia-bonding techniques, the use of an “MDP-containing primer” also appeared to have a positive effect.”

B. van Meerbeek et al: “Meta-analyis of Bonding Effectiveness to Zirconia Ceramics” J. Dent. Res. 93(4), 2014, 329-334.

“Based on the direct interaction of the phosphate-ester group of MDP with the metal oxides at the zirconia surface, a relatively favourable bonding effectiveness was recorded.”

B. van Meerbeek et al: “Durable bonding to mechanically and/or chemically pre-treated dental zirconia”, J. Dent. 41 (2013) 170-179.

“Clinical data provide strong evidence that air-abrasion at a moderate pressure in combination with using phosphate monomer containing primers and/or luting resins provide long-term durable bonding to glass-infiltrated alumina and zirconia ceramic under the humid and stressful oral conditions.”

M. Kern: “Bonding to oxide ceramics-laboratory testing versus clinical outcome”, Dent. Mater. Vol. 31 (1), 2016, 8–14.

“A high and reliable resin bond to alumina and zirconia ceramics was also achieved with airborne particle abrasion and by using a phosphate monomer (MDP) containing resin composite luting cement.”

M. Özcan et al: “Effect of surface conditioning methods on the bond strength of luting cements to ceramics”, Dent. Mat. 19, 2003, 725-732.

“In the present study, the use of the MDP-containing bonding/silane agent resulted in significantly higher bond strengths before and after long-term storage and thermal cycling with two types of resin luting agents.”

M.B. Blatz et al: “In vitro evaluation of shear bond strengths of resin to densely-sintered highpurity zirconium-oxide ceramic after long-term storage and thermal cycling”, J. Prosth. Dent. 91, 2004, 356-362.

“Dental zirconia can no longer be considered unbondable to tooth tissue (…) This also indicates that Al2O3 sandblasting is best followed by a chemical pre-treatment with an MDP containing primer.”

M. Inokoshi et al: “Meta-analysis of Bonding Effectiveness to Zirconia Ceramics”, J. Dent. Res. 93(4): 329-334, 2014.

“Airborne-particle abrasion of zirconia surface is one of the most-investigated methods, provides good bond strength to zirconia when combined with phosphate ester monomer.”

M. Ferrari et al: “Effect of surface pre-treatments on the zirconia ceramic–resin cement microtensile bond strength”, Dent. Mat. 27, 2011, 1024-1030.

“The data of the present work confirm the assumption of another study [13], that MDP bonds chemically to zirconia ceramic.”

C.H.F. Hämmerle et al: “Effect of thermocycling on bond strength of luting cements to zirconia ceramic”, Dent. Mat. 22, 2006, 195-200.

“An acidic adhesive monomer such as MDP shows chemical bonding to zirconia-based ceramics. The phosphate ester group of the acidic monomer results in chemical bonding to metal oxides (MxOy, oxidized surface of base-metal alloys), zirconia-based ceramics and other ceramics.”
