Durability of bond between an indirect composite veneering material and zirconium dioxide ceramics

Abstract

Application of a combination of hydrophobic phosphate monomer (MDP) and initiator results in a durable long-term bond between Katana zirconia and Estenia C&B composite material.

Shear bond strengths of an indirect composite layering material to a tribochemically silica-coated zirconia framework material

“…2 and 7B). The present findings can be explained by two factors: (1) bonding to a zirconia surface primed with phosphate monomer (a phosphate monomer improves bond durability between an indirect composite material and a zirconia framework) 17,28) , and (2) bonding to a silica layer treated with silane (3-TMSPMA) (the silane forms strong chemical bonds through a siloxane bond with embedded silica on the zirconia surface) 34,35) . Furthermore, it can be presumed that the acid functional phosphate monomer enhances formation of siloxane bonds.…”

“…Several studies found that the shear bond strength of indirect composite materials to zirconia frameworks was greater than 20 MPa 15,17) , which is above the threshold for clinically acceptable composite-metal and compositeceramic bonds 19,20) . Application of a combination of hydrophobic phosphate monomer (MDP) and initiator provided durable bonding between airborne-particleabraded zirconia and indirect composite material 15,17) . Fushiki et al 16) demonstrated that the use of a silane coupling agent and opaque material yielded stable bond strength of the indirect composite and feldspathicporcelain-coated zirconia, and suggested that feldspathic porcelain coating of zirconia frameworks was an effective method to achieve clinically acceptable bond strengths.…”

“…Previous studies of bond strength of layering porcelain to zirconia frameworks [11][12][13][14] indicated that values were comparable to those of layering porcelain to metal alloy. Indirect composite materials -an alternative to feldspathic porcelain for layering materials-have recently been introduced for use with zirconia-based restorations [15][16][17][18] . Several studies found that the shear bond strength of indirect composite materials to zirconia frameworks was greater than 20 MPa 15,17) , which is above the threshold for clinically acceptable composite-metal and compositeceramic bonds 19,20) .…”

In vitro comparison of fracture load of implant-supported, zirconia-based, porcelain- and composite-layered restorations after artificial aging

“…These characteristics of composite materials could improve the functional aspects of restorations, especially under conditions of high occlusal stress, such as those associated with implantsupported fixed restorations 10) . In vitro studies of bond performance between indirect composite materials and zirconia ceramics for zirconia-based composite-veneered restorations found that application of a hydrophobic phosphate monomer (MDP)/initiator combination resulted in satisfactory initial and durable bond strength between the two materials 14,15) . One study evaluated the fracture resistance of implant-supported, single-tooth, zirconiabased composite-layered molar restorations 16) , which have a potential fracture resistance comparable to that of porcelain-fused-to-metal and zirconia-based all-ceramic restorations.…”
