A dental post consisting of 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 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.

A method for fabricating a dental post consisting of fibre-reinforced material, wherein a composite structure of uniform cross-section with substantially uniformly directed light conducting fibers is formed in a pultrusion process and at least a portion of the circumferential surface of said composite structure is shaped to provide a tapered portion extending towards the second end of said composite structure such that at least a fraction of said light conducting fibers extend from the first end of said composite structure to the circumferential surface of said tapered portion.
A dental post consisting of 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, said post comprising a tapered portion extending over at least one third of its total length towards its second end, wherein at least one longitudinal groove is provided on the circumferential surface of said tapered portion, the course of said groove extending over part of the circumference of said post.
