“…After surface treatment, the samples were rinsed with distilled water, dried in an air furnace at 70 o C for 2 h, packed and sterilized with gamma radiation (25 kgray). The electrochemical micro-arc oxidation method has been described in previous studies [11,14,15].…”

“…Some mechanisms involved in osseointegration depend on whether the implant surface is smooth or rough, since cells react differently to these conditions. Fibroblasts and epithelial cells adhere more strongly to smooth surfaces, whereas osteoblastic proliferation and collagen synthesis are enhanced in rough surfaces [13,14].…”

“…According to Sul [14,15], the healing process around a dental implant with a treated surface occurs through a gradual mineralization process from the old bone to the implant surface. The healing time for dental implants without any surface treatment is longer than for implants with surface treatments.…”

Osseointegration has been defined as "a direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant". However, titanium and its alloys cannot directly bond to living bone after being implanted into the body. The osseointegration of titanium dental implants is critically dependent on the implant surface properties. Various surface modifications have been proposed in order to provide commercially pure titanium with bioactive bone bonding ability. In the present work, the titanium dental implant surface morphology was modified by acid etching and electrochemical treatments with the purpose of enhancing tissue response, and decreasing the waiting time for implant loading. The results show that surface morphology, topography, roughness and chemical composition were changed by the treatments and these changes has a significant influence on osseointegration. The best results were observed in the samples submitted to the electrochemical treatment.

“…The biocompatibility of titanium or its alloys is attributed to the oxide film formed on the material [1][2][3]. This oxide film promotes a good osseointegration and prevents the dissolution of metallic ions into the surrounding tissue [4].…”

The aim of this work was to perform thermal characterization of commercially pure titanium in dry air to determine its oxidation kinetics and the structure of the oxide. The oxidation kinetics were determined thermogravimetrically under isothermal conditions in the temperature range 300 to 750 o C for 48 hours and the structure of the oxides was determined by differential thermal analyses and X-ray diffraction in the temperature range room temperature -1000 o C. The oxidation rate of titanium increased with increase in temperature. It was high in the initial stages of oxidation and then decreased rapidly with time, especially up to 600 o C. The kinetic laws varied between inverse logarithmic at the lower temperatures (300 and 400 o C) and parabolic at the higher temperatures (650, 700 and 750 o C). Evidences from X-ray diffraction and differential thermal analyses data revealed that the passive oxide film formed at room temperature crystallized into anatase at about 276 o C. The crystallized oxide formed in the range 276 -457 o C consisted of anatase, in the range 457 -718 o C consisted of anatase and rutile sublayers, and at temperatures beyond 718 o C consisted of a layer of pure rutile. Scanning electron microscopy observations reveled that the oxidized surfaces were crack-free and the surface roughness increased steadily with oxidation temperature.Keywords: Titanium, oxidation kinetics, oxide film, structure. Cinética de oxidação de um titânio puro comercial RESUMOO objetivo deste trabalho foi de realizar uma caracterização térmica de um titânio puro comercial para estudar sua cinética de oxidação e seus produtos de corrosão formados em atmosfera de ar seco em função da temperatura. A cinética de oxidação foi determinada por termogravimetria em condições isotérmicas entre 300 e 750 o C por 48 horas e os óxidos formados foram caracterizados por análise térmica diferencial e difração de raios-X entre a temperatura ambiente até 1000 o C. A cinética de oxidação aumenta com a temperatura e é muito rápida nos primeiros instantes, diminuindo rapidamente com o tempo, especialmente até 600 o C. As leis cinéticas variaram entre a logarítmica inversa nas temperaturas mais baixas (300 e 400 o C) e a parabólica nas temperaturas mais altas (650, 700 e 750 o C). As análises por difração de raios-X e análise térmica diferencial mostraram que a cristalização do filme passivo de óxido, formado naturalmente à temperatura ambiente, ocorre aproximadamente a 276 o C. A estrutura do óxido é composta de anatásia cristalina entre 276 e 457 o C, anatásia e rutilo entre 457 e 718 o C, e somente rutilo acima de 718 o C. Observações por microscopia eletrônica de varredura revelaram que as superfícies oxidadas não apresentam fissuras e que suas rugosidades aumentam uniformemente com a temperatura de oxidação.Palavras-chave: Titânio, cinética de oxidação, filme de óxido, estrutura.

“…Titanium possesses high strength to density ratio, relatively low Young modulus value, very good corrosion resistance, and biocompatibility. For providing fast osseointegration and long-term usage in the human body, the implant surface should be modified, i.e., it should be rough or porous, oxidized, and covered by biocompatible coating including calcium-phosphate compounds [1][2][3]. Surfaces showing, micro-, and nanoirregularities are useful in biocompatibility improvements [4].…”

Engineers searching new dental biomaterials try to modify the structure of the material in order to achieve the best performance as well as increased migration and proliferation of cells involved in the osseointegration of the implant. In this work we show in vitro test results of the Ti, which was anodically oxidized at high voltages with additionally deposited silver in the form of nanodendrites. The in vitro cytocompatibility of these materials was evaluated and compared with a conventional microcrystalline titanium. During the studies, established cell line of human gingival fibroblasts (HGF) and osteoblasts were cultured in the presence of tested materials, and its survival rate and proliferation activity were examined. Titanium samples modified with silver has a higher degree of biocompatibility in comparison with the unmodified reference material. Cells in contact with studied material showed a higher relative viability potential, stable level of proliferation activity, and lower rate of mortality. Biocompatibility tests carried out indicate that the anodically oxidized titanium at high voltages with additionally deposited nanosilver could be a possible candidate for dental implants and other medicinal applications.
