لوحظ في الآونة الأخيرة زيادة تكاليف صناعة خلائط المعادن القاعدية , لهذا لجأت بعض المخابر السنية إلى إعادة صب الخليطة عدة مرات بالرغم من توصيات الشركة باستخدام الخليطة مرة واحدة , لذلك هدف هذا البحث هو دراسة تأثير إعادة صب خليطة (كوبالت- كروم) عدة مرات على انحناء الجسور المعدنية.
It was recently noted that the costs of the base metal alloy manufacturing have been increased, so some dental laboratories have recasted the alloy many times although the company's recommendations by using the alloy once. Therefore, this study aims to investigate the effect of re-casting the Co- Cr alloy several times on bridge bending.

It was recently noted that there are
serious trials to develop dental materials used in the prosthodontics.
As a result of this development, some veneering ceramic systems
used in metal-ceramic crowns have been appeared. In view of the
major impo
rtance of marginal fit and its role in the success of
restoration it must be a study and evaluation of marginal fit for these
modern systems.
This research aimed to comparasion of marginal fit for metal ceramic
crowns using two types of veneering ceramic.
Propolis is used directly on dentin to reduce dental sensitivity following posterior composite restorations. The research aims to test its effect on the bonding of composite to dentin in posterior composite fillings by scanning electron microscopy. T
he depth of penetration of the composite resin within the dentinal canals was evaluated by comparing the frequency of the presence of resin protrusions and measuring Their lengths and the thickness of the hybrid layer were measured in the three sample groups.
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
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

Vibration of Ultrasonic has used for scaling
and periodontal curettage, it is also has used for metal crown and
metal-ceramic crown removal, subsequently, using the tips whether for
scaling or removing crown, they will be in direct contact with th
is crown,
This research aimed to evaluate the surface of metal-ceramic crown
after exposure to Vibration of Ultrasonic tips.
