“…101,102 NDs significantly increased the impact strength of PMMA, and also improvement in fracture toughness was found, but only at the lowest concentration of NDs. 103 Moreover, heat-treated NDs increased the scratch resistance of PMMA. 104 Some drawbacks were attributed mainly to agglomeration of the NPs, which could act as points of stress concentration.…”

This paper reviews acrylic denture base resin enhancement during the past few decades. Specific attention is given to the effect of fiber, filler, and nanofiller addition on poly(methyl methacrylate) (PMMA) properties. The review is based on scientific reviews, papers, and abstracts, as well as studies concerning the effect of additives, fibers, fillers, and reinforcement materials on PMMA, published between 1974 and 2016. Many studies have reported improvement of PMMA denture base material with the addition of fillers, fibers, nanofiller, and hybrid reinforcement. However, most of the studies were limited to in vitro investigations without bioactivity and clinical implications. Considering the findings of the review, there is no ideal denture base material, but the properties of PMMA could be improved with some modifications, especially with silanized nanoparticle addition and a hybrid reinforcement system.

“…Recent research by Protopapaet al studied the mechanical properties of polymethylmethacrylate (PMMA) denture polymer reinforced by addition of 20nm nanoclusters of NDs. 46 They observed that the PMMA resin containing 0.83 wt% NDs, at 2084 MPa, had a much higher modulus of elasticity (Young's modulus) when compared to unmodified resin which had a modulus of 1184 MPa in addition to improved fracture resistance and impact strength. 61 However, properties such as bond strength of nanodiamond-composites to tooth structure and microleakage have not been studied yet.…”

Nanodiamonds (NDs) have been used in various fields of medicine such as drug delivery, tissue regeneration and gene therapy. Although there has been research carried out investigated the potential of these remarkable materials in dentistry, to date no review has been published to summarize the studies conducted.Due to their target cell specificity, small size and fluorescence they have also been found to be usefulness in dentistry. Main applications of NDs in dentistry and medicine include guided tissue regeneration, reinforcement of polymers and drug delivery to treat infections and cancers. Recent research also suggests that NDs can also be used as bioactive or antibacterial dental implant coatings. However, to date, the research conducted on their biocompatibility is limited and inconclusive. Hence, substantially more in vitro and in vivo studies are required to envisage the future of NDs in dentistry. It is hoped that in the next decade these promising materials will find a variety of uses in routine dentistry.

Revista da Escola de Odontologia da Faculdade Meridional r e s u m oObjetivos. Avaliar a infl uência do forma do fi o ortodôntico e sua posição vertical no reforço de uma resina acrílica utilizada para próteses parciais fi xas provisórias. Método. Foram confeccionadas 70 barras (25 x 3 x 3 mm) utilizando resina acrílica à base de polimetilmetacrilato com diferentes reforços (n = 10). Dois diferentes formatos da secção transversal do fi o foram avaliados: circular (C) e retangular (R). Três posições verticais do fi o também foram avaliadas: superior (S), mediana (M), inferior (I). Espécimes do grupo controle foram avaliados sem reforço. As diferentes condições experimentais foram avaliadas em teste de resistência à fl exão por 3 pontos em máquina universal de ensaios. Os dados foram analisados utilizando a análise de variância ANOVA (1-fator) seguido pelo teste de Tukey (α = 0,05). As restaurações provisórias, sejam próteses unitárias ou próteses parciais fi xas (PPF), devem cumprir funções importantes durante o tratamento, desde o preparo do dente até a fi nalização após cimentação da restauração fi nal (1-3). Os requisitos de uma restauração temporária são fornecer proteção pulpar, estabilidade posicional, manter a função oclusal, permitir higienização, possuir resistência, retenção e estética (4).Materiais contemporâneos para fabricação de restaurações provisórias unitárias ou múltiplas são principalmente à base de resina, e se diferem pelo método de polimerização, composição da carga, e tipo de monômero. Os mais utilizados são polimetilmetacrilato Introdução
