MDP showed high bond strengths to zirconia. [ 11 ] [ 12 ] Tensile bond strengths of MDP containing resin composites to zirconia ceramic were statistically significantly higher when compared with the bond strength of the conventional Bis-GMA resin composite which contains no adhesive monomer.
Adhesive dentistry is a branch of dentistry which deals with adhesion or bonding to the natural substance of teeth, enamel and dentin.It studies the nature and strength of adhesion to dental hard tissues, properties of adhesive materials, causes and mechanisms of failure of the bonds, clinical techniques for bonding and newer applications for bonding such as bonding to the soft tissue.

Zinc phosphate was the very first dental cement to appear on the dental marketplace and is seen as the “standard” for other dental cements to be compared to. The many uses of this cement include permanent cementation of crowns, orthodontic appliances, intraoral splints, inlays, post systems, and fixed partial dentures.
Dental composites. Glass ionomer cement - composite resin spectrum of restorative materials used in dentistry. Towards the GIC end of the spectrum, there is increasing fluoride release and increasing acid-base content; towards the composite resin end of the spectrum, there is increasing light cure percentage and increased flexural strength.
Glass ionomer cement is primarily used in the prevention of dental caries. This dental material has good adhesive bond properties to tooth structure, [8] allowing it to form a tight seal between the internal structures of the tooth and the surrounding environment. Dental caries are caused by bacterial production of acid during their metabolic ...
Zirconium dioxide (ZrO 2), sometimes known as zirconia (not to be confused with zirconium silicate or zircon), is a white crystalline oxide of zirconium.Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite.
Composition category 4 – polycrystalline solids (alumina and zirconia). Dental ceramic is generally regarded as biologically inert. However, other toxicities may exist from depleted uranium as well as some of the other accessory materials; in addition, the restoration may increase wear on opposing teeth.
Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide. These oxides are commonly called "zirconia" ( Zr O 2 ) and "yttria" ( Y 2 O 3 ), hence the name.
