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:...

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...
Introduction: New systems for adhesive cementation have been increasingly developed and used in daily clinical practice the of ceramic prostheses. Differences chemical composition various system components can influence bond strength between resin cement ceramic. Objective: This study aims to evaluate two systems—feldspathic porcelain yttria-stabilized zirconium oxide—and three different cementation: Rely X ARC, Multilink System, UCem. Methodology: Thirty discs Noritake feldspathic thirty...
Objective: To evaluate the strength of composite resins used for fabrication complete dentures after addition niobium pentoxide (Nb2O5). Methods: Different concentrations Nb2O5 were added to polymer matrix: 0% (control), 0.5%, 1.0%, 1.5%, and 2.0% per 100 mg resin. In this context, nanoparticles incorporated under ideal conditions, test specimens designed using Dentsply Sirona’s inLab MC XL software. After nanoparticles, samples printed with dimensions 25 mm in width, 2 height, thickness....
The objective of this study is to evaluate the accuracy and precision full arch maxillary digital scans produced by six scanners. Materials Methods: A standard model was scanned a reference scanner obtain model. This same then ten times three intraoral scanners benchtop scanners, which are: CS3600 (Carestream Health, Rochester, New York, USA), iTero element 2 (Align Technology, San José, California, Trios (3Shape, Copenhagen, Denmark), Ceramill Map 400 (Amann Girrbach, Koblach, Feldkirch...
A cavidade oral apresenta características bastante abrangentes para o desenvolvimento de microorganismos e é considerada uma abertura a entrada dos mesmos. Microrganismos causados pela boca podem causar infecções generalizadas, como pneumonia sepse. Em pacientes internados em unidades terapia intensiva (UTIs), muitas dessas complicações ser evitadas caso tratamento esteja vinculado um atendimento odontológico. Esses atendimentos são feitos nas luvas realizados por cirurgiões dentistas da...
O novo Coronavirus (SARS-CoV-2) representa um desafio para a Organização Mundial de Saúde (OMS) e os sistemas saúde no Brasil em todo o mundo. vírus possui alta transmissibilidade é responsável pela doença Covid- 19, causadora quadros respiratórios que variam leves graves (Zhou et. al, 2020). Poucos meses após início da epidemia na China final 2019, já haviam mais 2 milhões casos 120 mil mortes mundo por COVID 19 (Werneck, Carvalho, Essa nova rápida progressão tem provocado gerando...
The aim of this study is to assess how shear strength Ultra Translucent Multi Layered Zirconia Katana (UTML) affected by the conditioning with 10% hydrofluoric acid combined current surface treatment protocol: air, primer containing 10-MDP, and cement. Samples UTML were machined measure 5x5x10 units measurement, attached, divided into two groups. In control group, samples treated 27 um aluminum oxide blasting at 4 bars, application Zr 10-MDP and, finally, cement Panávia V5. experimental also...
The 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 divided into two groups: G1(PEEK + TAR) G2 (Zantex TAR). Each group was subdivided subgroups A, B, C, D E (n=10) according pre-treatment: A: TAR PEEK/Zantex without treatment (control); B: treated Palabond; C: blasted aluminum oxide (Al2O3) 125 µm; D: PEEK /Zantex Al2O3 µm E:...
The aim of this study is to test and compare the flexural strength milled polymer bars, with without glass fiber reinforcement. number samples in was defined through a pilot on universal testing machine (EMIC) (n = 5). brands analyzed were Arch Free Metal, Zantex, Bioplas PEEK.
