Titan und seine Legierungen sind in salzhaltigen und sauren Umgebungen besonders korrosionsbeständig. Obwohl Titanlegierungen aufgrund der Stabilität der TiO 2 -Oxidschicht außergewöhnlich korrosionsbeständig sind, sind sie nicht inert gegenüber korrosiven Angriffen. Wenn die stabile Oxidschicht abgebaut oder entfernt wird und sich auf Teilen der Oberfläche nicht mehr neu bilden kann, kann Titan genauso korrosiv sein wie viele andere unedle Metalle.Die Mundhöhle kann unter bestimmten Umständen eine elektrochemische Zelle simulieren. Obwohl Titan eine bessere Korrosionsbeständigkeit...

Maintenance for complete dentures is a role that must be undertaken by the patient. It has been determined that two minutes of microwave irradiation at 650 Watts provides denture disinfection, and three minutes provide sterilization. There is insufficient data on how this practice affects the long term dimensional stability of commonly used complete denture bases in the United States. Contamination of removable prostheses with microorganisms (e.g. bacteria, fungi or viruses) turns them into sources of infection risk that may affect denture wearers and dental professionals. It is imperative...

Titanium and its alloys give greater resistance to corrosion in saline and acidic environments. Even though titanium alloys were exceptionally corrosion-resistant because of the stability of the TiO 2 oxide layer, they are not inert to corrosive attack. When the stable oxide layer is broken down or removed and is unable to reform on parts of the surface, titanium can be as corrosive as many other base metals.The oral cavity can simulate an electrochemical cell under certain circumstances. Although titanium shows better corrosion resistance, it may interact with living tissue in several years....

The initial treatment plan for implant dentistry is based on ideal implant size and diameter to optimize maximal aesthetics. When teeth are replaced with dental implants, the dentist should pre-select the ideal abutment size based on the ideal size for an aesthetic restoration. The size of an implant is determined primarily by the existing bone volume in height, width and length. Longer implants are selected in the anterior regions of the mouth and shorter ones in the posterior areas because of the limits of the mandibular canal and maxillary sinus. Dental implants transfer loads to...

Le titane et ses alliages offrent une plus grande résistance à la corrosion dans les environnements salins et acides. Même si les alliages de titane sont exceptionnellement résistants à la corrosion en raison de la stabilité de la couche d'oxyde TiO 2, ils ne sont pas inertes aux attaques corrosives. Lorsque la couche d'oxyde stable est décomposée ou retirée et qu'elle est incapable de se reformer sur certaines parties de la surface, le titane peut être aussi corrosif que de nombreux autres métaux de base.La cavité buccale peut simuler une cellule électrochimique dans certaines...
