ظهرت مؤخرا مادة FiltekP90 التي تحمل شعار " الترميمات ذات التقلص التصلبي الأقل ". و هي من مواد الكومبوزيت الهجين التي تعتمد تقنية السيلوران الذي يحتوي على المونوميرات ذات الحلقة القابلة للفتح. تناول البحث اختبار كل من مقاومتي الالتواء و الاهتراء لمادة Filtek ذات الأساس السيلوراني مع مادتي Tetric- Evo Ceram و Tetric Ceram HB ذات الأساس الميتاكريلاتي لتقويم مدى تأثير تغيير القالب الراتنجي في هاتين الخاصتين.
Ring-opening monomers with a reduced shrinkage stress “silorane" are being used as matrix resins for recently introduced dental composites. Thisstudy aimed to analyzethe mechanical behavior(Flexural StrengthFS, Abrasion Resistance AR) of the silorane-based composite (Filtek P90) in comparison to two methacrylate-based composites (Tetric- Evo Ceram & packable hybridTetric Ceram HB).

This research includes an experimental study for the manufacture of
a composite material based on polymer (unsaturated polyester),
reinforced with random fiberglass at different weight fractions. By
suite, it has been studied some mechanical prope
rties of the models
manufactured, to determine the effect of glass fiber content on the
tensile strength, hardness and impact resistance. This study has
shown that the best results were for samples reinforced by 40%
fiberglass, where the tensile strength increased about 70%, hardness
up to 30%, and impact resistance about 43%. It will be observed
that the mechanical properties decrease clearly at 60% of weight
fraction of fiberglass. This fact can be related to the quantity of
unsaturated polyester become inadequate for recharge of the fibers,
which leads to weakness in the forces bonding in composite
materials.
The aims of this study were to evaluate the microleakage in the Class II Cavities Restored with methacrylate resin composite (Tetric Ceram HB) or silorane resin composite (P90 Filtek) that had been stored in different situations and temperatures. Mat
erials and Methods: thirty six intact human upper first premolars were employed. Two Class II cavities with specific dimensions had prepared on each tooth mesially and distally. Teeth were Restored by Methacrylate Resin (HB IVOCLAR), Silorane Resin (P90), Under three different conditions: Group (A): application of composite and Adhesive System at room temperature (24°C), Group (B): application of composite and Adhesive System, immediately after removal from refrigerator temperature (4°C), Group (C): application of composite and Adhesive System, 30 minutes after removal from the refrigerator at room temperature (24°C).Results: This study observed a statistically significant increase in microleakage when applying each of methacrylate composite (HB IVOCLAR) and silorane composite (P90) immediately after removal from refrigerator temperature (4°C) Compared when applied at room temperature (24°C) and when applied 30 minutes after removing from refrigerator temperature, no significant differences were found between silorane composite (P90) and Methacrylate composite (Tetric HB) in microleakage when comparing the two types of resin in the three ways used in storing both resins.
The research project sample consisted of 30 blocks of composite resin , these blocks where divided into three equal groups , 10 of composite resin Z-250 from 3M ESPE Company , 10 of the composite resin Supreme from 3M ESPE Company ,10 of the composit
e resin Quixfil of Dentsply company, and has been testing the hardness Number, each sample individually. The aim of the previous procedures was to show the role of composite resin structure in determining the hardness number Through differences in the hardness number and the role of this hardness determining the mechanical properties for composite resin restorations cause of the importance of this property to understand the mechanical properties for a lot of restorative materials. And the result is that there is a statistically significant between the resin Quixfil and the Z-250 on the one hand and the Supreme resin on the other hand.
Because of large industrial development which the world has seen in
all fields. scientists and researchers aim to produce new materials
that having special engineering properties with low economic cost as
fit multiple industrial application and us
es. So in This present
article We try to prepare composite materials based on aluminum
alloy (6663) and reinforcement it by different particles having size
of micron of Alumina and silicon carbide particles are added in
specific weight parentage by stir casting
technique to obtain Aluminum Which having the improving
mechanical properties
foamed concrete is a concrete made by cement slurry mixed with foaming agent, so
that foamed concrete is lighter than conventional concrete. The objectives of this study is
to produce this kind of concrete, and to study some of its physical and mec
hanical
properties. Mix design of concrete was made for four required densities (1000,
1300,1600,1900 kg/m3), cement content of 350 kg/ m3, and water to cement ratio equal to
0.5. Different tests were performed to determine some properties of product concrete such
as density, compressive strength and splitting tensile strength. The results demonstrated the
possibility of production foamed concrete with wide range of density and strength. The
oven dry density of foamed concrete was in the range of (870-1773 kg/m3) , compressive
strength was in the range of (2.95-16.2 Mpa ), and the splitting strength was in the range
of (0.32-1.76Mpa).
