In this study, 3D printing resins were evaluated, using digital light processing technology, verifying their accuracy. For this, a plaster model was produced from prefabricated synthetic resin model, which scanned by SHINING bench scanner, generating an STL file. This file used as reference measurements, they printed printer, DLP Anycubic Photon, thirty models (N=30) with 3 different (n=10), namely: Low Smell Skin, Prizma - Model DM-300 and Smart Print LCD Model. After the also scanned. The...
Introduction: Composite resins are highly aesthetic restorative materials, with nanohybrid being the most indicated for anterior tooth restorations due to their excellent physical and mechanical properties, gloss, surface smoothness, good wear resistance. The fabrication of using CAD/CAM system has become increasingly widespread in field Dentistry. is a technology widely used various industries was introduced into Dentistry late 1970s. These technologies based on three essential phases:...

Desde que foram registrados os primeiros contágios, uma infecção por coronavírus (Covid-19) deu maneira bastante rápida. Neste cenário, dentre EPI's (Equipamentos de Proteção Individual), mais ganharam destaque no combate à doença as máscaras cirúrgicas como forma prevenção desse contágio. Alguns protocolos devem ser seguidos para usar correta. Além das cirúrgicas, nos casos aplicáveis, faz-se necessário o uso proteção respiratória. No entanto, e respiratória cirúrgica vem desempenhando um...
This study assessed, through finite element analysis, the biomechanical behavior of an implant system using All-on-Four® technique with nickel-chromium (M1) and polyether ether ketone (PEEK) bars (M2).Implants components were represented in three-dimensional (3D) geometric models submitted to three types load: axial, oblique, load on all teeth. The 3D exported a computer-aided design-like software such as Solidworks 2016 (Dassault Systemes, Corps, USA) for editing Nonuniform Rational Basis...
Em dezembro de 2019, um surto pneumonia começou na China e se espalhou por várias regiões geográficas, sendo causado pelo vírus que chamamos Coronavírus, ou como muitos chamam, Covid -19. Os dados acerca do relatam o mesmo apresenta uma elevada capacidade infecção. Levando em conta as características atendimento odontológico, incluem proximidade face a entre os cirurgiões-dentistas pacientes, faz-se necessário cuidado redobrado relação ao manejo paciente, limpeza consultório proteção dos...
This study aims to assess the biomechanical behavior of alveolar bone surrounding implants over protocol with metal, Polyether ether ketone (PEEK) and Zantex bars, in normal osteoporotic conditions. For simulation, geometric models mandibular arch were designed containing 5 two variables. The first variable is condition - osteoporotic-, second material used bars – PEEK Zantex. Simulation was performed using Finite Elements Method. Results showed that largest load peaks concentrated medullary...
The aim of this study is to analyze the compressive strength occlusal splints manufactured with three different liquid resins in a 3D printer and angles orientation. used here are (n=12): Resilab Clear (Wilcos do Brasil, Petrópolis, RJ, Brazil), Prizma Smart Print Bio (Makertech Labs, Tatuí, SP, Cosmos Splint (Yller Biomateriais, Pelotas, RS, Brazil); each resin group divided into subgroups according orientation manufacture: 0, 45 90 degrees. A dental manikin was scanned file manufacture...
Abstract Aim: This study aimed at evaluating with the three-point flexural test, bonding strength of tetragonal zirconia polycrystalline stabilized by yttria zirkonzahn (Y-TZP) and two coating ceramics (Ice e Vision Zircon), surface treatments (treated untreated). Materials Methods: Forty Y-TZP bars were divided into four groups (n = 10): vision zircon/without treatment (VZ/woT), zircon/with (VZ/wT), ice/without treatment, ice/with (I/wT). The assay was conducted using a 50 N load cell 1...
