“…Yang et al [ 7 ] reported that porcelain cracking was relatively common in zirconia all ceramic restorations, with a 3-year cracking rate of 1.95% for posterior single crowns and a 2-year cracking rate of 2.5%–14.9% for 3-4 units of fixed bridges. To avoid phenomena such as porcelain cracking in all ceramic restorations, choosing a reasonable zirconia surface treatment becomes a common focus among scholars [ 8 ]. Although glass-ceramics treatment has a good repair effect in dental defects, it is difficult to meet the clinical needs because it fails to reach the expected shade covering, aesthetics effect and restoration effect.…”

“…Nanohybrid resin composites with 40 nm zirconia nanoparticles presented improved and more stable physical properties compared with commercial dental composites or composites reinforced with nanosilica [97]. In a recent study, zirconia nanofillers were incorporated in bis-GMA composite resins [98] up to 5-20 wt%. SEM images indicated spherical particles with sizes ranging between 20 and 50 nm, and a significant increase in bending strength was recorded for the composites.…”

“…Os cimentos resinosos fotopolimerizáveis são materiais ativados apenas fisicamente por luz, por meio de reações químicas, em que cadeias carbônicas são quebradas para que moléculas se unam firmemente ao polímero, resultando numa reação exotérmica (MAGNE; KNEZEVIC, 2009;SHIMOKAWA et al, 2017). O sucesso nas propriedades mecânicas, estabilidade de cor e solubilidade dos cimentos ao longo do tempo, bem como a dureza e a resistência ao estresse de compósitos resinosos (HONG et al, 2020;ILIE et al, 2017), dependem da eficiência dessa fotoativação na conversão de monômeros em polímeros (DEDE et al, 2017;GUGELMIN et al, 2020;HONG et al, 2020). Somado a isso, fatores como opacidade e espessura da cerâmica podem interferir negativamente na transmissão da luz através destes materiais, o que também pode comprometer a polimerização do agente cimentante e interferir negativamente na durabilidade do procedimento restaurador (COELHO et al, 2019;YILDIRIM;RECEN;TEKELI SIMSEK, 2021).…”

“…Com o advento da nanotecnologia, alguns compósitos passaram a apresentar alto conteúdo de partículas de carga (com aproximadamente 0,02 nm na matriz resinosa), que envolvem dois tipos de partículas: nanométricas e nanoaglomeradas (HONG et al, 2020).…”
