Abstract: The invention relates to a dental implant configured to be anchored in a jawbone for supporting a dental prosthesis. In order to allow an adjustment of the tooth restoration structure to properties of a natural tooth the dental implant includes a jacket member which includes at least in part an osseo-integratable material and enclosing a cavity in an apical direction, and a filling member of fiber reinforced material and being shaped so as to substantially fill out the cavity.

Abstract: The invention relates to an abutment for connecting a dental prosthesis to a dental implant, the abutment including a body portion for supporting the dental prosthesis and a contact surface apical to the body portion for contacting the dental implant. In order to allow an adjustment of the tooth restoration structure to properties of a natural tooth the abutment is composed of a resin that is reinforced with fibers substantially extending over the total length of the body portion towards the contact surface.

Abstract: A dental post has fibre-reinforced material with substantially uniformly directed fibers and mountable in a tooth root canal for fixing a dental prosthetic structure on a tooth stump and a method for its fabrication. For improving the light conduction properties within the post, at least a fraction of the fibers conduct light, and includes post a tapered portion extending toward its second end. Some of the fibers extend from the first end of said post to the circumferential surface of the tapered portion. According to a fabrication method of the post a composite structure of uniform cross-section with substantially uniformly directed light conducting fibers in a pultrusion process. At least a portion of the circumferential surface of the composite structure is shaped to provide a tapered portion extending toward the second end of said composite structure.

Abstract: A dental post consisting of fiber-reinforced material with substantially uniformly directed fibers and mountable in a tooth root canal for fixing a dental prosthetic structure on a tooth stump and a method for its fabrication. For improving the light conduction properties within the post, at least a fraction of said fibers are adapted for light conduction within said post and said post comprises a tapered portion extending towards its second end, wherein at least a fraction of said light conducting fibers extend from the first end of said post to the circumferential surface of said tapered portion. An advantageous fabrication method of the dental post comprises forming of a composite structure of uniform cross-section with substantially uniformly directed light conducting fibers in a pultrusion process and shaping of at least a portion of the circumferential surface of said composite structure in order to provide a tapered portion extending towards the second end of said composite structure.

Abstract: The tooth root channel anchorage assembly comprises a core member to be fixed within the tooth root channel and a post to be inserted into the core member having a thoroughgoing bore. The core member comprises a crown part and an anchorage part to be fixed within the root canal, the surface of the anchorage part having a substantially hyperbolic form. Preferably the crown part of the core member as well as a part of the surface of the post have also a substantially hyperbolic form. The hyperbolic form allows a better anchoring and distributing of the load, thus reducing the danger of breaking of the post and root canal, still allowing the access to the root canal before the post is inserted.

Abstract: The tooth root canal point is made of a synthetic material reinforced with glass or carbon fibers and not of the usual gutta percha. When inserted with bone cement, the result is a solid but not completely rigid post that conforms to the contours of the tooth root canal and ensures a high stability of the tooth.
