“…Occlusal antagonists were upper first premolars extracted for orthodontic or periodontal reasons without modifying the buccal cusp tip. (33)(34)(35) It was reported that extracted human enamel is more desirable for collecting information that may guide clinical practice. (36)(37)(38) Also, studies that didn't use enamel and used ceramics instead as antagonist, ignored the fact that the enamel roughens during wear more than the ceramic thus affecting further wear and abrasiveness to the opposing.…”

Objective: Wear and microhardness of three different types of CAD/CAM ceramics against enamel as an occlusal antagonist were studied. Also, microhardness was evaluated. Materials and Methods: The three tested ceramics were: Vita Enamic (polymer-infiltrated ceramic), IPS e.max CAD (lithium disilicate ceramic) and Celtra Duo (Zirconia reinforced lithium silicate ceramic). The occlusal antagonists were extracted teeth. Thirty samples were constructed divided into 3 groups according to the type of ceramic used (10 samples each). Then each group was subdivided into 2 subgroups (5 samples each), The first subgroups underwent a microhardness test while the other subgroups were first weighed then subjected to wear test and finally re-weighed again before being subjected to microhardness test. Results: The results showed a significant difference in weight loss due to wear between Vita Enamic and both IPS e.max CAD and Celtra Duo. There was also a significant difference for the antagonist tooth structure as regard both weight and height loss between Vita Enamic and both IPS e.max CAD and Celtra Duo. Microhardness results showed a significant difference between Vita Enamic and both IPS e.max CAD and Celtra Duo as regard microhardness without and after wear. For all the tested ceramics, there was no significant difference as regard microhardness without and after wear test. Also, there was no significant difference as regard wear and microhardness between IPS e.max CAD and Celtra Duo. Conclusions: Vita Enamic showed the worst wear behavior and the least abrasiveness to enamel while, IPS e.max CAD and Celtra Duo showed comparable wear behavior and abrasiveness to enamel. Also, ceramic microhardness was not affected by wear for the three tested ceramics.

Kompozit rezinlerin 1962 yılında Bowen tarafından tanıtılmalarıyla başlayan süreçte, hastaların estetik beklentisinin artması ve amalgam hakkındaki endişeler kompozit rezinleri tercih edilen materyal haline getirmiştir. Kompozit rezinlerin estetik olması, konservatif kavite preparasyonuna imkan sağlaması ve tamir edilebilmesi avantajlarının yanı sıra polimerizasyon büzülmesi, fonksiyonel tüberküllerde kullanımında aşınma direncinin az olması gibi dezavantajları bulunmaktadır. 1960'ların başından günümüze kadar kompozit rezinler hakkında çeşitli araştırmalar yapılmış, kompozit rezin materyali geliştirilmeye çalışılmıştır. Geliştirilen özellikler ve bu alanda yapılan araştırmalar ile kompozit rezinlerin dezavantajlarının elimine edilmesi hedeflenmiştir. Bununla birlikte literatürde kompozit rezin ile ilgili hem in vivo hem de in vitro araştırmalar ın sayısı da artmıştır . Literatürdeki in vivo araştırmalarda hastaların yaşı, cinsiyeti ve incelenen toplam hasta sayısı gibi hastaya ait veriler yer almakla birlikte kullanılan materyaller, materyallerin klinik değerlendirme kriterlerine ait veriler, restorasyon ömrü gibi veriler de çalışmanın değerlendirilen verileri arasında yer almaktadır. Bu makalede, kompozit rezin restorasyonlar ve diğer restoratif materyaller ile ilgili literatürde yapılan 2010 ve sonrası in vivo ve in vitro çalışmalar derlenmiş ve bu çalışmalarda yer alan tüm veriler incelenerek tablolar halinde sunulmuştur.

“…The variation of hardness values between all composite restoratives surfaces can clarify the variation in the rate of wear. Consequently, it found that the wear of restorative materials is determined by some factors, especially the hardness of the restorative material [15]. Both the surface roughness value and wear affected the strength of the resultant composites that was increased with a decrease of surface roughness and has significant differences for the same surface roughness values with different directions of scratch [16].…”

In this work, it was evaluated the wear resistance, hardness, and surface roughness values of resin-based composites that applied in dentistry as restorative materials. The resin composites were made from six types of resin matrixes (A, B, C, D, E, and F) and each one of them has contained different types and ratios of monomers as well as the inorganic nanofillers (SiO2, ZrO2, HA, and Al2O3). For each test, thirty specimens were prepared, which were classified into six groups depending on the types of the resin matrix and fillers used in the composites. The results prove that the nanocomposites that have the lowest rate of wear were the group E which was derived from the resin matrix of the group E that has monomers are (BIS-GMA, meth acrylamide, methacrylic acid, and 1-6 hexanediol methacrylate) with values range from 8.11 to 6.11 mm 3 /mm depending on the filler type material. All prepared composites resin materials (A to F) showed an increase in their hardness values as regards the reference, group D showed the highest hardness value followed by group B while group C was the lowest. The highest mean roughness was shown in groups A and F with 0.82 and 0.79 μm respectively, while the smoother surfaces among all groups were groups B and D which had significantly fewer roughness values of 0.16 and 0.19 μm respectively.
