The present invention is generally related to implants for compensating bone loss in mammalian body, and to devices and methods for replacing or creating facial bone. The present invention relates to devices and methods for implanting an implantable device in a subject's body. The implantable device embodying features of the present invention include a body formed from a rig or matrix having a trabecular meshwork structure or cells with shapes suitable for a particular anatomical area of interest. The device may be a dental implant serving as a platform for placement of dental crowns.

Provided are dental articles, and methods of making articles, having an aesthetic inorganic coating based on zirconia at least partially stabilized with yttrium oxide, calcium oxide, cerium oxide, or magnesium oxide. Stabilized zirconia coatings were found to provide a smooth, low friction surface having high abrasion resistance. These coatings are particularly applicable to orthodontic appliances. While virgin stabilized zirconia coatings can often have an undesirable color cast, it was discovered that this color cast can be substantially eliminated by heat treating the coated appliance in an oxygenated environment. The combination of depositing a stabilized zirconia coating and subsequently heat treating to decolorize the coating provides a surprisingly robust, stable, low-friction coating that is also aesthetic.
