Patent ID: 8197256

Claim:
A fiber optics dental post, including: a resin body, in which the resin body includes an outer peripheral face, a receiving irradiation portion, and a bottom; and a plurality of fiber optics center shafts, in which each of the fiber optics center shafts pierces through and is fixed in the resin body for shaping, and has a receiving irradiation end and a light-guide irradiation end; each receiving irradiation end placed on the receiving irradiation portion of the resin body is used to receive a light irradiating on the receiving irradiation portion, and each light-guide irradiation end is respectively placed on the outer peripheral face and at the bottom of the resin body, thus the light received by each receiving irradiation end is propagated to the outer peripheral face and the bottom of the resin body through the light-guide irradiation end for irradiation; a plurality of stepped ring edges having a plurality of exposed fibers, said stepped ring edges are disposed on the outer peripheral face of the resin body; and; wherein at least one of the light-guide irradiation end has an opening, wherein said opening is oblique so as to propagate the light to at least some of the exposed fibers on the stepped ring edges.
