The biomechanics of the bone and of metal, Zantex and PEEK bars in normal and o...
Franco, Aline Batista Gonçalves; Carvalho, Geraldo Alberto Pinheiro de; Franco, Amanda Gonçalves; Napimoga, Juliana Trindade ClementeThis study aims to assess the biomechanical behavior of the alveolar bone surrounding the implants over protocol with metal, Polyether ether ketone (PEEK) and Zantex bars, in normal and osteoporotic conditions. For the simulation, geometric models of the mandibular arch were designed containing 5 implants and two variables. The first variable is the bone condition - normal and osteoporotic-, and the second is ...
Shear bond strength of resinous cements to Zirconia Katana™ UTML
Martins, Mariana Cristina Teixeira; Franco, Amanda Gonçalves; Carvalho, Geraldo Alberto Pinheiro de; Dias, Sérgio Candido; Martins, Caio MarquesThe aim of this study is to assess the bond strength of three resinous cements to Zirconia Katana™ UTML (Kuraray Noritake Dental Inc, Miyoshi, Aichi, Japan). Thirty-six blocks of Zirconia were milled and included in polyvynil chloride (PVC) pipes with self-polymerizable acrylic resin. Each sample was polished in a polishing machine, blasted with aluminum particles, cleaned with ultrasound, and dried with compre...
Análisis de la resistencia adhesiva de postes de fibra de vidrio sometidos al e...
Grecco, Patrícia; Dias, Sérgio Candido; Coimbra , Walace Henry Miranda; Pascutti , Flávia Pires Neves; Franco, Aline Batista GonçalvesEl objetivo fue evaluar la resistencia al cizallamiento por extrusión y verificar el tipo de falla de postes de fibra de vidrio que han recibido diferentes tratamientos de superficie, y testar el adhesivo multiuso Single Bond Universal® (3M ESPE). Métodos: Ochenta incisivos bovinos con tratamiento endodóntico fueran aleatoriamente repartidos en cuatro grupos; Grupo I: los postes recibieron aplicación de silano;...
Influence of different surface treatments on the shear strength between acrylic...
Fonseca, Tácio Gonçalves Nogueira; Franco, Amanda Gonçalves; Carvalho, Geraldo Alberto Pinheiro de; Martins, Caio Marques; Mecca Junior, SilvioThe present study assesses the shear strength of Polyether Ether Ketone (PEEK) and Zantex to thermopolymerizable acrylic resin (TAR) with different surface treatments. To this end, 100 test specimens were produced and divided into two groups: G1(PEEK + TAR) and G2 (Zantex + TAR). Each group was subdivided into the subgroups A, B, C, D and E (n=10) according to surface pre-treatment: A: TAR + PEEK/Zantex without...
