COATED DENTAL ARTICLES AND RELATED METHODS OF MANUFACTURE

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.

IMPLANT SURFACE COMPOSITION
20170079752 · 2017-03-23 ·

An implant structure or parts thereof having a surface composition obtainable through an anodic oxidation process is disclosed. The surface composition comprising titanium oxide in the anatase crystalline phase and at least 90% of the pores have an orifice with a mean inside diagonal distance of less than 0.1 m. It is also disclosed an implant system comprising said surface composition and a method of obtaining said surface.

IMPLANT BODY

The present invention provides an implant body formed from metal or ceramics as a raw material, the implant body including a modified surface, provided with a plurality of projections and a plurality of crevasse-like nanoscale grooves, by which focal adhesion formation, penetration of collagen fibers, arrangement of the collagen fibers in a single direction to thereby adhere to connective tissue, and soft tissue sealablity are possible. According to such a surface modification, focal adhesion formation and the arrangement of the cell cytoskeleton can be enhanced, and penetration of collagen fibers into the surface internal portion is possible.

POROUS IMPLANT DEVICE WITH IMPROVED CORE
20170049536 · 2017-02-23 ·

An implant device has an exterior portion forming an exterior surface of the implant. The exterior portion is made of a porous material defining passages through the exterior portion. An inner portion has an outer surface with a treated area that is accessible from the exterior surface through the passages. The treated area has a treatment for direct attachment to bone or soft tissue.

DENTAL COMPOSITIONS AND METHODS OF USE
20170035662 · 2017-02-09 ·

Provided herein are high performance dental restoration compositions, particularly two-part compositions having good self-cure times. Also provided herein are methods for restoring or filling a cavity in a tooth in an individual with the two-part dental restoration compositions. In particular, compositions provided herein are useful in restoring large cavities, including Class I and Class II cavities.

Dental regenerative device made of porous metal

A regenerative device can include a first side section, a second side section, and a top section extending between and connecting the first side section and the second side section. The top section and the first and second side sections can each be formed from a porous material that retains its structure after implantation in the patient. The regenerative device can be used for ridge augmentation of a maxilla or a mandible. The top section can include an opening configured for receiving an implant. The porous material can be permanently implanted in the mouth and promote bone regeneration or ridge augmentation. One or both of the first and second side sections of the device can include one or more openings or apertures for receiving a fastener to secure the device to the alveolar ridge.
