“…The sliding antagonist was a zirconia ball, 4 mm in diameter (YTZ ball, Nikkato, Osaka, Japan) serving as the antagonist "cusp" and loading the mounted CAD/CAM block specimens at 15° angulation along a 3.7 mm sliding path 9) . At the end of each sliding cycle the ball was automatically lifted and returned to the zero position for the following sliding cycle (50 N, 1.2 Hz).…”

“…The discs were mounted with adhesive resin (Panavia SA Cement, Kuraray, Okayama, Japan) in cylindrical aluminum molds, immersed in deionized water at 37°C for 7 days, and wet-ground on SiC papers, #600, #1,500 and #4,000. Two reference points were created using a diamond round point (#40, Shofu, Kyoto, Japan) on the peripheral area covered by an aluminum container for slurry 9) . Then specimens were ultrasonically cleaned in water for 5 min.…”

The aim of the study was to investigate two-and three-body wear of CAD/CAM blocks. Four composite resins, one hybrid ceramic and one feldspar ceramic block material were examined. Six specimens each were tested in a ball-on-disc wear device fitted with a zirconia ball (50 N load, 1.2 Hz, 50 k cycles) in water for two-body and in poppy seed slurry for three-body wear evaluation. Volume loss after each 10 k cycle was quantified using a digital CCD microscope. Statistical analysis: ANOVA and Tukey's multiple comparisons (α=0.05). Two-body wear for composite resin blocks was small, hybrid ceramic and ceramic blocks showed larger volume loss. Threebody wear was very low for all materials. All CAD/CAM block materials investigated displayed low wear compared to previous data for direct posterior composites carrying out the same wear test. The block materials are considered suitable for fabrication of single full crown restorations on premolar teeth.

“…The PMMA beads were mixed with distilled water in a 3:1 ratio. The comparative evaluation using both generalized and localized wear tests is important to better characterize resin composite wear, as the same resin composite exhibited different wear behavior in two-body and three-body wear tests in a previous study 16) . In the current study, extracted human teeth were used for the generalized wear test to simulate clinical conditions.…”

The purpose of this study was to examine three-and two-body wear values of flowable resin composites for posterior restorations, using a mechanical loading device. The cavities prepared on flattened extracted molars were restored with flowable resin composites (Clearfil Majesty LV: MLV, Estelite Flow Quick: EFQ, Beautifil Flow Plus F00: BFP, and MI Fill: MIF) using accompanying adhesive systems. A universal resin composite (Clearfil Majesty) was used as a control. The specimens were subjected to in vitro three-and two-body wear testing. MLV showed high wear value (three-body: 14.69 µm, two-body: 0.268 mm 3 ) compared with other materials tested in both three-and two-body wear tests. BFP showed high three-body wear value (5.78 µm), whereas low two-body wear value (0.008 mm 3 ). MIF and EFQ showed equivalent wear values (MIF, three-body: 0.42 µm, two-body: 0.026 mm 3 ; EFQ, three-body: 1.15 µm, two-body: 0.14 mm 3 ) to that of the control in both wear tests.

“…However, nanoparticle resins, due to their large percentage of inorganic load, have low polymerization shrinkage and because of the size of the particles, have excellent polishing. This new generation of composite resin can certainly be used in both anterior and posterior teeth due to the superior mechanical and aesthetic properties they possess 7 . In general, today composite resins with microhybrid, nanohybrid and nano particles are mainly used.…”

“…However, with the development of hybrid resins with improved wear resistance 1 , there has been increased interest in using this type of resin in posterior teeth 5 . In this context, nanotechnology has allowed the development of resins with excellent mechanical and aesthetic properties related to good polishing and less shrinkage 6 , and may be employed both in anterior teeth as well as posterior teeth 7 . Thus, the microhybrid, nanohybrid and nano particle composite resins are considered universal in use and are also indicated for the restoration of posterior teeth.…”

RESUMOAs restaurações de resinas compostas têm aumentado consideravelmente em popularidade e previsibilidade, possibilitando a realização de um tratamento odontológico minimamente invasivo. No entanto, para se obter o sucesso das restaurações de resina composta é necessário ter conhecimento dos materiais adesivos e da técnica de utilização, caso contrário os insucessos podem aparecer rapidamente. Assim, o objetivo deste trabalho foi realizar uma revisão de literatura sobre o desempenho clínico de diferentes tipos de resinas compostas e de sistemas adesivos no que se refere à longevidade. Para essa avaliação foram verificadas algumas características das restaurações logo após elas serem finalizadas e depois de um determinado tempo. Características como sensibilidade pós-operatória, cor, integridade marginal, cárie secundária, textura, adaptação marginal, retenção, deslocamento, descoloração marginal, forma anatômica, tiveram seus desempenhos comparados. A influência dos vários sistemas adesivos na longevidade das restaurações foi também observada em função da sua fundamental importância na união entre o dente e o material restaurador. Concluiu-se que a maioria das restaurações se apresentou clinicamente aceitável, quando se usou resinas compostas híbridas, nanoparticuladas ou microhíbridas e sistema adesivo convencional.
