Abstract:

High strength ceramic components for use in dental applications are provided with a bonding layer disposed thereon to increase the bonding properties of the ceramic component in order that the ceramic component may better bond to a resin material, ceramic material or composite material. Moreover, the bonding layer provides strength to the ceramic component by forming a compressive layer thereon. The ceramic component may be partially or fully embedded in composite material. The ceramic component is bonded to the composite material either by mechanical means, chemical means or both. The material may be placed directly on the ceramic component. Alternatively, the structural component is coated with a bonding layer to provide adhesion between the composite or like material and the structural component.

International Classification:

A61C 1300

US Classification:

264 16, 264 19, 264642

Abstract:

Process for the manufacture of dental restorations using high strength ceramic components. A wax pattern is built around a high strength ceramic component on a die. The wax pattern with the high strength ceramic component is surrounded with investment material. The wax is burned out, leaving a mold with the high strength ceramic component. The mold is filled with a ceramic material, covering the high strength ceramic component, creating a dental restoration.

US Classification:

419 5, 419 9, 264 19, 433206, 433207, 433208, 433209

Abstract:

Dental restorations are fabricated using metal powder. Preferably, the metal powder is a high fusing metal and preferably, the metal powder comprises a non-oxidizing metal. The metal powder is applied to a die and is covered with a covering material such as a refractory die material preferably in the form of a flowable paste. A second covering material may be sprinkled or dusted onto the paste. The model is then dried prior to firing. After drying, the model is sintered to provide a high strength metal restoration. After sintering, the outer shell can be broken off easily with ones hand to expose the sintered coping.

Abstract:

Lithium disilicate based glass-ceramics contain high strength ceramic components for use in the manufacture of dental products. The glass-ceramics have good pressability, i.e., the ability to be formed into dental products by heat-pressing using commercially available equipment. The strength of the dental articles is increased with the inclusion of the high strength ceramic components.

Assignee:

Jeneric/Pentron Incorporated - Wallingford CT

International Classification:

A61C 1312
A61C 13225
A61C 508

US Classification:

433180

Abstract:

The present invention relates to unique dental structures such as bridges and crowns. The bridge comprises a structural component such as a fiber reinforced polymeric matrix bar disposed within interproximal cavities located in the distal occlusal surface of the mesial abutment tooth and the mesial occlusal surface of the distal abutment tooth. A structural wrap and/or occlusal strip comprising fibers embedded within a polymeric matrix can also be employed where the wrap is attached to one or both abutment teeth and one or both sides of the structural component. The occlusal strip is attached to the occlusal surface of both of the abutment teeth, spans the edentulous area, and is attached to the top surface of the structural component. Meanwhile, the crown comprises a wrap disposed around and adhered to a damaged natural tooth and may have an occlusal strip adhered to the occlusal surface of the natural tooth where the wrap is disposed around the edge of the occlusal strip. In both embodiments a pontic can then be built up around the structures to form the final product.

Abstract:

The present invention relates to unique dental structures such as bridges and crowns. The bridge comprises a structural component such as a fiber reinforced polymeric base material impregnated bar disposed within interproximal cavities located in the distal occlusal surface of the mesial abutment tooth and the mesial occlusal surface of the distal abutment tooth, and a support element of woven fibers and polymeric base material. The support element can span the endentulous area, wrap around the structural component, and provide support for the veneer on the pontic.
