Background
Resin bonded fixed partial dentures appeared to prevent the excessive preparation of dental
tissue
Investigation of surface treatments to improve the bond of resin cements to metals may contribute
to the longevity of these restoration
s. Due to the potential lack of ideal preparation form the type of alloy
and its surface pretreatment may have clinically relevant correlations with the retentive strength of castings
to minimally retentive preparations
Aim
The aim of this search is to study the bonding resin cement strength to different types of the metal
alloy due to the surface treatment
Purpose Evaluate the effects of two different surface treatments on shear bond strength SBS between a
palladium silver alloy Pb Ag and commercially pure titanium CP Ti cast alloy with resin luting cements

Objective: is to study the effect of colored (non-opaque) adhesive resin cement and opaque adhesive resin cement on color matching of full ceramic crowns set on severe discolored abutments.
Materials and Methods: Sample consisted of 15 full cerami
c (IPS e-max press) crowns (A1 Vita Classical Guide) set on severe discolored abutments (ND9) and divided into 3 equal groups (1) left without adhesive (2) adhered with colored Adhesive Resin Cement (3) adhered with opaque Adhesive Resin Cement. The color of these full ceramic crowns was analyzed in the cervical, medium and incisal third using digital color analyzer (Easy Shade Compact); and the values of color change (∆E) were studied and compared with (∆E) of one full ceramic (IPS e-max press) crown (A1 Vita Classical Guide) set on non-discolored abutment (ND1).
Results: showed that White Opaque (WO) Adhesive Resin Cement improved the ∆E values in the full ceramic crowns bonded on severe discolored abutments, were relatively better than the colored cement. However, both kinds of the cements did not reach a color matching level that we can clinically accept.
This study aims to evaluate zirconia bond strength bonded with resin cement
after deferent surface treatments.
Partial veneer crown has appeared to prevent the excessive preparation of
dental tissue with complete crown and the major reason success of this prosthesis could be strength of
cementation.
Therefore the latest studies have been focusing on develo
ping new material and technique to increase the
bonding strength and using new technique for surface treatment or change type of metal alloy.
The aim of this search is to study the bonding resin cement strength to different type of metal alloy due to
surface treatment.
The purpose of this in vitro study to evaluate the effect
of ceramic primer on the bond strength of adhesive resin cement to
zirconia ceramic surface.
