1. Mg-Containing Hydroxyapatite Coatings Produced by Plasma Electrolytic Oxidation of Titanium
Plasma Electrolytic Oxidation (PEO) is promising for the processing of biomaterials because it enables the production of surfaces with adjustable composition and structure. In this work, aimed at the improvement of the bioactivity of titanium, PEO has been used to grow calcium phosphide coatings on titanium substrates. The effects of the addition of magnesiu

2. The effect of standardised implantoplasty protocol on titanium surface roughness: an in-vitro study
Abstract: To analyse the changes of surface characteristics of machined and moderately roughened titanium disks following a standardised implantoplasty protocol. Forty titanium discs (machined: n = 20; moderately roughened: n = 20) were instrumented with one half of each disc maintained as the control (non-instrumented). The standardised implantoplasty proto

4. Effect of a cordless retraction paste on titanium surface: a topographic, chemical and biocompatibility evaluation
Good exposure of the preparation margins and haemostasis in the sulcular gingiva are necessary for accurate impressions to produce precise restorations. The use of cordless retraction paste material in implant dentistry is a relatively novel application. However, few studies have been conducted on the use of retraction pastes and their possible interaction w

5. Proliferation of human periodontal ligament mesenchymal cells on polished and plasma nitriding titanium surfaces
AIM: To evaluate the proliferative capacity of mesenchymal cells derived from human periodontal ligament on polished and plasma-treated titanium surfaces. METHODS: Eighteen titanium disks were polished and half of them (n=9) were submitted to plasma nitriding using the cathodic cage technique. Mesenchymal cells were isolated from periodontal ligament of impa

6. Citocompatibilidade de discos de titânio tratados com cobertura usando nanotecnologia de prata / Cytocompatibility of titanium disks treated using silver nanotechnology
Os componentes protéticos que fazem a união entre implante e prótese são importantes para a manutenção da saúde peri-implantar sendo responsáveis pela vedação permucosa e impedindo a penetração de agentes químicos ou bacterianos desencadeadores de processos destrutivos nas estruturas ao redor do implante. Assim faz-se importante o desenvolviment

7. Estudo das alterações superficiais de um substrato cerâmico e titãnio rugoso irradiado com laser de ER, CR. YSGG. / Study of surface changes of a ceramic substrate and titanium irradiated with rough ER, CR. YSGG.
O objetivo deste estudo foi investigar os efeitos do laser de érbio cromo dopado com ítrio, escândio, gálio e granada (Er,Cr:YSGG) com parâmetro de descontaminação, na rugosidade superficial (Sa) em zircônia tetragonal policristalina estabilizada com ítrio (Y-TZP) e titânio com jateamento de partículas grandes e ataque ácido (SLA) (TI). Métodos:

8. Effect of whitening toothpaste on titanium and titanium alloy surfaces
Dental implants have increased the use of titanium and titanium alloys in prosthetic applications. Whitening toothpastes with peroxides are available for patients with high aesthetic requirements, but the effect of whitening toothpastes on titanium surfaces is not yet known, although titanium is prone to fluoride ion attack. Thus, the aim of the present stud

9. Effect of titanium surface on secretion of IL1β and TGFβ1 by mononuclear cells
Mononuclear cells play an important role in the modulation of healing. The characteristics of implant surface topography may alter the production of signaling molecules such as cytokines. The aim of this in vitro study was to evaluate the effects of commercially available titanium surface treatments on both cell viability and the secretion of the antagonist

10. Comparative study of two cp Ti casting methods. / "Estudo comparativo de dois métodos utilizados na fundição de titânio cp"
Along the last decade, several jobs have been highlighting the advantages of titanium and titanium alloys and studied the possible utilization for removable partial dentures (RPD) metal frameworks confection. Although advantages, the cast process still presents problems, limiting the titanium use. The objective of this study was to evaluate the influence of
