Description
Ahmad Abdulkareem Alnazzawi and four co-authors test, in 2024 lab work, laser-sintered metal posts against cast ones for fit. Such posts anchor crowns in teeth whose roots have been treated, and each must match its root space just so. The cast route is old and slow; the laser route builds the post layer by layer from a scan.
A clear block with a drilled post space gave the master shape. Ten posts were built each way in a cobalt-chrome mix, and a triple-scan check weighed each against the true form. Both sets strayed from the mark by a like hair's breadth, with no real gap between them. The team calls the laser route a sound swap that saves cost and time.
