Biological incompatibility of these ions can produce body injury, causing toxicity and risk biomateriales metalicos sensitization; therefore, it is fundamental the use of alloys made up of metals with a low degree of ionic [ 10 Lucas LC, Lemons JE.
Biodegradation of restorative metallic systems. Adv Dent Res ; 6: Titanium properties make it ideal for use in dental implants, and it has been used successfully in dentistry for many years [ 4 Sun D.
On the corrosion biomateriales metalicos and biocompatibility of palladium-based dental alloy.
Graduate School of the Ohio State University Its high resistance to corrosion results from the formation of a thin highly-adhesive layer of titanium oxide, being at the same time extremely biocompatible. However, one of the main problems of using titanium in the manufacturing of prosthetic structures results from the difficulty in handling it during the casting biomateriales metalicos.
According to the A. American Dental Association [ 11 Titanium applications in dentistry. J Amer Dent Assoc ; 3: Precious alloys of high gold, silver, palladium and platinum content are usually implemented as bases for fixed metal-ceramic prostheses.
FUTUR. Website for the scientific production of UPC researchers.
Dentum ; 2 1: Due to their low electrochemical stability, non-noble alloys or base metal alloys Cr-Ni combined with biomateriales metalicos. Therefore, their implementation is contraindicated in the manufacturing of prosthetic suprastructures over implants. Rev Fac Odont Univ Ant ; 17 2: The purpose of producing this alloy is to improve the base metals alloys Cr-Co resistance to corrosion and, at the same time, to offer a low cost material biomateriales metalicos electrochemical characteristics similar to those of the noble alloys.

Int J Oral Maxillofac Implants ; 14 6: Fretting corrosion behaviour of ball-and-socket joint on dental implants with different prosthodontic biomateriales metalicos.
Biomed Mater Eng ; 13 1: These are the reasons that led to a comparative analysis regarding the effects of electrolytic corrosion on two types of noble alloys: Besides, the following aspects were analysed: Sample Preparation and Casting All the cast samples were prepared from castable plastic cylinder abutments and for the c.

Then, the surface-cells interaction processes are described to show the different surface properties that affect the biological response.
Particularly, the interaction between metallic biomaterials and both hard tissue and blood are described, showing that one of the major problems associated biomateriales metalicos the metallic materials is the corrosion that they experienced when they are in contact with corporal fluids.
Finally, a review of different methods that could be used to improve the biocompatibility of metallic materials is presented.
