The use of metals and their alloys in restorative and implant dentistry dates back to centuries. Titanium (Ti) is one of the most widely used biomaterial for medical implants because of its excellent mechanical properties and exceptional biocompatibility. The good biocompatibility of Ti is related to the thin oxide layer formed on Ti surface. TiO 2 is inactive with the surrounding biological environment and quite compatible with living tissues. However, TiO 2 layer can be destroyed during movements between implant and bone tissue under loading condition. The localized destruction causes corrosion of the implant, thus, weakening it; and can induce the leak of small metallic particles or ions into living tissues. This article highlights a review of the various aspects of corrosion and biocompatibility of dental titanium implants as well as suprastructures, and the methods to prevent it.
Provider response in making treatment changes after an episode of hypoglycemia is suboptimal. Standardized protocols to make changes in diabetes treatment after an episode of hypoglycemia need to be tested.
Extraction of the first molar or premolar is the commonest cause of oro-antral fistula. Management involves identification of the same, removal of any foreign body from the maxillary sinus, if present, followed by appropriate flap for closer. A case is presented when a gutta percha (GP) point was accidentally dislodged into the right maxillary sinus during preliminary diagnosis of the oro-antral fistula. The surgical management of the case is described and is the appropriate treatment plan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
