A dental post having a support frame captured and interlocked thereon, and encaptured in a luting material, preferably such as a moldable self-curing tooth-colored composite material to create a laminated composite/metal foundation complex for retaining a dental rstoration securely on a tooth stub. The post includes a smooth cone-shape lower end portion for matchingly fitting into a prepared tooth canal, a threaded portion passively fitting in the tooth canal for engagement with the composite material, an unthreaded portion to provide greater strength, a square portion to permit the dental post to be unscrewed from the hardened composite material, a tapered portion, and a chisel-like portion at the upper end of the dental post. The support frame includes a pair of opposing legs for straddling the dental post and a bight portion connecting the legs together, the bight portion having a slot for receiving the chisel-like portion therethrough, a pair of pads extending transversely outwardly from the lower ends of the legs for seating in steps formed in the tooth stub, elongated slots formed in the legs to receive the composite material therethrough and to permit the bifurcated leg portions to be twisted to reinforce the structure of the legs. The chisel-like portion is inserted through the slot in the bight portion, and then turned 90 degrees to capture and interlock the dental post and the support frame together.
