خلفية البحث ظهرت التعويضات الجزئية المرتبطة بالراتنج ذات التحضير الأصغري كحلٍ مناسبٍ لتجنب التحضير الزائد للنسج السنية، إلا أن هذه التعويضات تفتقر إلى الثبات، ولعل السبب الرئيسي المؤدي لنجاحها هو قوة إلصاقها، ولهذا تركزت الدراسات الأخيرة حول تطوير مواد و تقنيات جديدة لزيادة متانة ارتباط و التصاق هذه التعويضات ومنها إيجاد طرق جديدة في معاملة سطح التعويض الداخلي أو بتغيير نوع الخليطة المستخدمة الهدف من البحث يهدف البحث إلى دراسة متانة ارتباط الاسمنت الراتنجي المستخدم في إلصاق التعويضات الجزئية مع نوعين من الخلائط المعدنية باستخدام طرق مختلفة في معاملة السطح المعدني ترميل و تطبيق مهيئ معدني
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 restorations. 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

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.
The aim of this study To compare in vitro shear bond strength (SBS) of different
orthodontic adhesives in and rebonding metal brackets after preparing their bases
mechanically.
Material and methods:Sample consisted of 40 extracted first premolars,
randomly
divided into two groups (n=20),.Adhesive removed by tungsten carbide bur later the
brackets were rebonded. The tests were performed in a tecnotest (6kN) SBS testing
machine, at a speed of 1 mm/min.
It was found that the mean shear bond strength of Reseliencewas 19.25 MPa and that
of Heliosit orthodontic was 10.25MPa.We foundthat the mean shear bond strength of
rebonding forReselience was 13.70 and 7.95 forHeliosit.The t-test revealed that there was a
significant difference between the shear bond strength of the two groups.
We found a significant difference between bonding and rebondingfor
Reselience,while there was no significant difference between bonding and rebonding for
Heliosit.
With the increase in the number of adult patients seeking orthodontic treatment, the need to ensure sufficient bonding strength for the fixed orthodontic components on the ceramic restorations has become an urgent matter. Adhesion of the orthodontic
bracket is an essential and indispensable step.
