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.
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

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.
Background and Aim : Retention between composite and fiber post is still below the acceptable level when compared with the retention between composite and dental structure. This study aimed to evaluate the effect of H2O2 as a chemical solution to imp
rove the mechanical connection between fiber post and composite core. Materials and Methods:45 glass fiber posts and 45 quartz fiber posts were prepared. The specimens were randomly distributed into 3 subgroups, including application of silane (S) , etching with H2O2 10% for 20 minutes(H1) , etching with H2O2 20% for 10 minutes (H2). composite core was placed. Shear bond strength values of posts and composite resin cores were measured using a mechanical test machine (Instron). data were analyzed Statistically . Results :There were significant differences between the shear bond strength for (H1,H2) And (S) in quartz groups only (P<0.05). There was no significant difference between glass and quartz groups (P>0.05). Conclusions:The surface treatment of quartz fiber posts with H2O2 significantly enhanced the shear bond strength of the composite core. Application of H2O2 to the Glass fiber post surfaces was not effective.
Since the solution of direct bonding of orthodontic brackets as an alternative to full encircling of the dental arch, researchers have begun conducting studies to evaluate the adhesion materials and different methods of enamel preparation to reach the most appropriate method for the requirements of ideal adhesion.
