An artificial tooth 30 to be polished is fixed at a tooth neck 32 side and rotated about a tooth axis 33. Abrasives, preferably elastic abrasives formed by kneading abrasive grains into or supporting abrasive grains on an elastic material, are ejected together with a compressed gas at an ejection pressure of from 0.1 MPa to 0.5 MPa onto an occlusal portion 31 side of the artificial tooth 30 while the artificial tooth 30 is being rotated. The abrasives are ejected at an inclination angle with respect to the tooth axis 33 of the artificial tooth 30 of from 0 to 90, and preferably from 15 to 75. Portions on the occlusal portion 31 and side surfaces 38 of the artificial tooth 30 are thereby polished at the same time by the abrasive sliding over these portions.

Embodiments of the present invention provide devices (tags with sensors), systems, and methods to determine states (such as, but not limited to, complex impedance) of materials-of-interest, such as tissue-of-interest, implants, and construction members, to name a few, in a non-invasive and contactless way; and using comparatively safe and/or low energy electromagnetic radiation, such as radio waves. Negligible-sized wireless-tags with sensors are implanted in such materials-of-interest. Using wireless communication and imaging technology, the states of the materials-of-interest may be monitored; which may allow non-invasive and contactless detection of problems such as cracking, bending, excessive pressure, improper temperature, and/or the like. Additionally, initially unknown locations of the implanted negligible-sized wireless-tags with sensors may be readily determined upon a given scanning (reading) session; and thus mapped to provide an effective image of the material-of-interest.

A dental prothesis configured to be placed in a gap between a first adjoining tooth and a second adjoining tooth so as to replace a missing tooth. The prothesis includes two partial abutments configured to sit within the gap between the two adjoining teeth. Secured to each partial abutment is a connector which is also secured to one of the adjoining teeth. Each connector is in a substantially C-shape configuration and adapted to fit along the surface of the associated adjoining tooth. The connectors have a plurality of connecting points that are adapted to fit within one of a plurality of retention grooves ground in the adjoining teeth to affix the connectors to the adjacent teeth with little grinding of the adjacent teeth. A crown is adapted to fit over and about the two partial abutments.

An intra-procedure dental implant stabilization and healing system that includes a soft tissue forming scanning abutment and associated, temporary crown. After initial implant placement, a scanning abutment of the present system is attached to the implant and serves, both as a scanning body and, in combination with a temporary crown attached thereto, as a healing cap. Use of the system obviates an additional surgical incision to reach recipient osseointegrated implant, as is required in conventional implant procedures, as well as the need for a conventional impression coping, separate healing cap, temporary abutment and temporary crown.

A dental restoration, a method for the production of a dental restoration and a kit. The dental restoration comprises an outer component, in particular a shell, and an inner component, in particular a core. The inner component and the outer component contain composite material. The outer component is mountable or mounted on the inner component. The inner component is designed for attachment onto a tooth preparation, in particular a tooth stump.

A natural and sustainable material is derived from the nut of the tagua palm tree that may be fashioned into devices for humans and animals. A pulverized and reconstituted material is disclosed herein that is also treated with a low temperature atmospheric plasma treatment. In an embodiment, a biocompatible carrier gas is ionized to form a biocompatible atmospheric plasma stream. Material, such as nano-scale powdered hydroxyapatite, is introduced into the plasma stream, which is then applied to the natural nut material.
