الهدف: دراسة دور الإسمنت الراتنجي الملوَّن غير الظليل والإسمنت الراتنجي الظليل على التطابق اللوني للتيجان الخزفية الكاملة المتوضعة على دعامات متلونة بشكل شديد. المواد والطرق: تألفت العينة من 15 تاجاً خزفياً كاملاً (IPS e-max press) بلون A1 حسب دليل Vita الكلاسيكي متوضعة على دعامات متلونة بشكل شديد (ND9) تم تقسيمها إلى ثلاث مجموعات متساوية: الأولى تركت بدون إلصاق والثانية أُلصقت بإسمنت راتنجي ملون A1 والثالثة أُلصقت بإسمنت راتنجي ظليل تم تحليل لون هذه التيجان الخزفية في كل من الثلث العنقي (1 ملم) والمتوسط (1.2 ملم) والقاطعي (1.5 ملم) باستخدام جهاز تحديد اللون الرقمي Easy Shade Compact ثم دراسة التغير اللوني E∆ لكل منها ومقارنة النتائج مع القراءات المأخوذة من تاج خزفي شاهد من اللون A1 متوضع على دعامة ذات شدة تلون ND1. ثم تمت مقارنة قيم مقدار التغير اللوني المقيس على التيجان الخزفية في عينة البحث بالقيم المعيارية التي تم قياسها في التاج الخزفي الشاهد. النتائج: أظهرت الدراسة أن الإسمنت الراتنجي الأبيض الظليل استطاع تحسين قيم E∆ للتيجان الخزفية الكاملة الملصقة على دعامات متلونة بشدة بشكل أفضل نسبياً من الإسمنت الراتنجي الموافق للون التاج إلا أن كليهما لم يصل لمستوى تطابق لوني مقبول سريرياً.
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 ceramic (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.

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.
Usually, it's hard to reach the final color identity with normal teeth when using
full glass ceramic, but this matter is very important for the cosmetic successful of these restorations. This
in vitro study evaluated the effect of cement color on the final color of full crown glass ceramic of system
IPS e.max.
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

internal fit of lithium disilicate glass ceramic laminate veneers
fabricating using heat-pressing technique and cemented using two
types of adhesive resin cement.
This study aims to evaluate zirconia bond strength bonded with resin cement
after deferent surface treatments.
