Integrated support devices for providing temporary primary stability to a dental prosthesis implant, each individually designed and manufactured for a specific pre-identify patient are also provided. An integrated support device can include a prosthesis interface member configured to connect to an abutment or reduced sized portion of a dental prosthesis/implant. The integrated support device also includes one or more bonding wings for connecting to the adjacent healthy teeth.

Disclosed herein is an article comprising a first screw and a second screw, the first screw being reversibly attached to the second screw such that a longitudinal axis of the first screw coincides with or is parallel to a longitudinal axis of the second screw; the first screw and the second screw each comprising a biodegradable composition, the biodegradable composition comprising a metal or metal alloy comprising magnesium, strontium, zinc, calcium or a combination comprising at least one of the foregoing. Methods of making and using the article are also disclosed herein.

Dental implant with a base body made of ceramic anchorable in a jawbone and an implant superstructure attachable to the base body using a screw, wherein in an assembled state of the dental implant, a threaded portion of the screw engages with an inner thread formed in a blind hole of the base body, wherein the implant superstructure is by the screw pressed against the base body and wherein the engagement between the threaded portion of the screw and the internal thread of the blind hole occurs only in a lower half of the base body facing away from the implant superstructure.

The invention relates to an apparatus for releasable attachment of a removable dental prosthesis to a head part of an implant or of an abutment that can be anchored in an implant, comprising a retention matrix (1) having a receptacle that accommodates a circular-ring-shaped retention element (2) that has at least two clamping arms (22), which is disposed so as to be displaceable along a center axis of the retention matrix (1), wherein the at least two clamping arms (22) form a mantle surface that widens conically toward the outside, and that the receptacle for the retainer element (2) has two sections (14, 15) having a different inside diameter, against the transition of which the at least two clamping arms (22) lie. The invention furthermore relates to a dental implant system, having such an apparatus.

A custom dental implant and a method and system for making the custom dental implant having one or more energy storing devices that deflect during installation and expand to provide stability after insertion in a natural dental socket of a patient.

A ceramic composite material and a method for producing same. The ceramic composite material has a ceramic matrix comprising zirconium oxide and at least one secondary phase dispersed therein. The matrix is composed of zirconium oxide as at least 51 vol.-% of composite material, and the secondary phase is in a proportion of 1 to 49 vol.-% of composite material, wherein 90 to 99% of the zirconium oxide is present in the tetragonal phase based on the total zirconium oxide portion. The tetragonal phase of the zirconium oxide is stabilized by at least one member selected from the group consisting of chemical stabilization and mechanical stabilization. The ceramic composite is damage-tolerant.

The present invention relates to a fixation implant with an implant body which is made substantially of a ceramic material and has an external helical thread with more than one thread web and wherein a thread pitch angle of the external helical thread is in the range from 30° to 90°, and to the use thereof as an alloplastic bone implant, as an alloplastic dental implant, in production engineering, medical engineering, surgery, dental technology and/or implant technology.

The present invention provides a zirconia sintered body that has less excess material to be removed when making a prosthesis by milling, providing a reduction of work time, more durability for a working tool, and a faster treatment for patients, and that undergoes little deformation during firing, and provides enhanced aesthetics. The present invention relates to a columnar zirconia sintered body having a base and a side face, the base having a surface shape that is neither square nor rectangular but has at least one straight portion.

An implant for anchoring a tooth replacement includes an endosseous part comprising a ceramic sleeve at a first end of the endosseous part. The endosseous part is configured to be embedded to a full height of the endosseous part in a bone.

Provided is a superstructure (3) coupled to a fixture (2) that is made of pure titanium or a titanium alloy and planted in a jawbone, the superstructure (3) including: a framework (5) made of a cobalt-chromium alloy; an artificial tooth (4) bonded to the outer surface of the framework (5); and a coupling member (6) made of a gold alloy and joined to a lower part of the inside of the framework (5) to couple the framework (5) to the fixture (2), wherein the framework (5) and the coupling member (6) are integrated by being soldered together with a solder (10) composed of a gold alloy containing gold and silver.
