Genotoxicity of corrosion eluates obtained from endosseous implants
(Lippincott Williams & Wilkins, 2007-03-01)
Purpose: Commercially pure titanium alloys are currently used as metallic biomaterials in implantology. Corrosion phenomena appear to play a decisive role in metallic implant long-term behavior. Thus, the goal of this study ...
The Effect of Coating Patterns with Spinel-Based Investment on the Castability and Porosity of Titanium Cast into Three Phosphate-Bonded Investments
(Wiley-Blackwell, 2010-10-01)
Purpose: This study evaluated the effect of pattern coating with spinel-based investment Rematitan Ultra (RU) on the castability and internal porosity of commercially pure (CP) titanium invested into phosphate-bonded ...
Efficacy of Air-abrasion Technique and Additional Surface Treatment at Titanium/Resin Cement Interface
(Quintessence Publishing Co Inc, 2012-08-01)
Purpose: To evaluate the effect of surface treatments on the shear bond strength (SBS) of a resin cement to commercially pure titanium (CP Ti).Materials and Methods: Two hundred cast CP Ti disks were divided into 5 groups ...
Hydroxyapatite deposition study through polymeric process on commercially pure Ti surfaces modified by laser beam irradiation
(Springer, 2009-08-01)
Many techniques have been used to coat metallic substrate with bioceramics. The aim of this study was to study the physical-chemical characteristics of polyvinylidene fluoride (alpha-PVDF)/hydroxyapatite (HA) composite ...
Desenvolvimento da Tecnologia de Soldagem do Titânio pelo Processo TIG Orbital no Segmento Aeroespacial Brasileiro - Parte 2: Caracterização das Juntas Soldadas
(Associação Brasileira de Soldagem (ABS), 2007-04-01)
In this work, three welding programs for orbital TIG previously developed were used, using pulsed current and increasing speed (M), constant current (#B) and pulsed current and decreasing current (#C). One of those should ...
Análise metalográfica do titânio puro submetido à soldagem laser Nd: YAG e TIGMetallographic analysis of pure Ti submitted to Nd: YAG laser and TIG welding
(Universidade Estadual Paulista Júlio de Mesquita Filho, 2015)
Titanium surface topography after brushing with fluoride and fluoride-free toothpaste simulating 10 years of use
(Elsevier B.V., 2012-04-01)
Objectives: To conduct a controlled study contrasting titanium surface topography after procedures that simulated 10 years of brushing using toothpastes with or without fluoride.Methods: Commercially pure titanium (cp Ti) ...
Analysis of the bioactive surface of Ti-35Nb-7Zr alloy after alkaline treatment and solution body fluid
(2013-02-28)
The purpose of this work was to evaluate the Ti-35Nb-7Zr experimental alloy after surface treatment and soaking in solution body fluid (SBF) to form bonelike apatite. The Ti-35Nb-7Zr alloy was produced from commercially ...
