Journal ArticleDOI
Effect of 2% chlorhexidine on microtensile bond strength of composite to dentin.
Fabrício Luscino Alves de Castro,Marcelo Ferrarezi de Andrade,Sillas Duarte,Luis Geraldo Vaz,Fernando Jorge Mendes Ahid +4 more
TL;DR: The 2% chlorhexidine solution, applied before or after acid etching of the dentin, did not interfere with the microtensile bond strength of composite resin to dentin treated with Prime & Bond NT, Single Bond, or Clearfil SE Bond bonding systems.
Journal ArticleDOI
Development of binary and ternary titanium alloys for dental implants
Jairo M. Cordeiro,Thamara Beline,A.L.R. Ribeiro,Elidiane Cipriano Rangel,Nilson Cristino da Cruz,Richard Landers,Leonardo Perez Faverani,Luis Geraldo Vaz,Laiza Maria Grassi Fais,Fábio Bossoi Vicente,Carlos Roberto Grandini,Mathew T. Mathew,Cortino Sukotjo,Valentim Adelino Ricardo Barão +13 more
TL;DR: The alloying elements proved to modify the alloy microstructure and to enhance the mechanical properties, improving the hardness and decreasing the elastic modulus of the binary and ternary alloys, respectively.
Journal ArticleDOI
Influence of Implant Connection Type on the Biomechanical Environment of Immediately Placed Implants – CT-Based Nonlinear, Three-Dimensional Finite Element Analysis
Roberto Sales e Pessoa,Luiza Muraru,Elcio Marcantonio Junior,Luis Geraldo Vaz,Jos Vander Sloten,Joke Duyck,Siegfried Jaecques +6 more
TL;DR: The implant-abutment connection design did not significantly influence the biomechanical environment of immediately placed implants and avoiding implant overloading and ensuring a sufficient initial intraosseous stability are the most relevant parameters for the promotion of a safe biomechanicals environment in this protocol.
Journal ArticleDOI
Retention force and fatigue strength of overdenture attachment systems.
TL;DR: The systems evaluated showed satisfactory retention force values, before and after fatigue testing, and a 5-year simulation of insertion and removal did not decrease retention values or fracture components.
Journal ArticleDOI
The volumetric fraction of inorganic particles and the flexural strength of composites for posterior teeth.
TL;DR: New condensable composites for posterior teeth present a concentration of inorganic particles similar to those of hybrid composites but do not necessarily present higher flexural strength.
