Claim Text:
1. A dental post configured to be mounted in a tooth root canal for fixing a dental prosthetic structure on a tooth stump, the dental post comprising: a fibre-reinforced material comprising a resin matrix and fibres substantially uniformly directed, a fraction in a range of at least 40% and at most 80% by volume of a total content of said dental post comprising said fibres and at least a fraction of said fibres being configured to conduct light within said dental post; and a tapered portion extending towards a second end of said dental post, the tapered portion extending over at least one half of the total length of the post, the slope of said tapered portion increasing toward said second end with respect to a longitudinal axis of said post, wherein at least a fraction of said fibres extend from a first end of said dental post to a circumferential surface of said tapered portion, such that each fiber ends at a different point of said circumferential surface so as to provide homogeneous light irradiation over a total length of the circumferential surface by the light conducted by said fibres, wherein first ends of the light conducting fibres are positioned at said first end of the post, and the first ends of the fibres are planar cut and at least one of grinded and polished such that the first ends of the fibres are configured as light entering surfaces, and wherein said resin matrix comprises a urethane dimethacrylate in which an ytterbium compound is embedded.
