IMPLANT HAVING A BONE GROWTH POWDER/BIOMEDICAL FILLER ROTARY PUSH STRUCTURE

摘要

An implant includes an implant base having a predetermined diameter, a positioning thread spirally upwardly extended around the periphery thereof and gradually reducing in width in direction from the implant root toward an opposing top side thereof to form a gum-drilling structure, a plurality of spiral grooves equiangularly and upwardly extending around the periphery thereof across the positioning thread to form a plurality of cutting edges at the positioning thread at different elevations, and an arc top located at the top side thereof. The diameter of the implant root and the number of the spiral grooves are determined subject to a predetermined ratio so that the implant can be conveniently and rapidly driven into the dental bone to simultaneously propel the applied bone growth powder/biomedical filler into place, assuring a high level of implant reliability.

1. An implant, comprising an implant base having a predetermined diameter, a positioning thread spirally upwardly extended around the periphery thereof and gradually reducing in width in direction from said implant root toward an opposing top side thereof to form a gum-drilling structure, a plurality of spiral grooves equiangularly and upwardly extending around the periphery thereof across said positioning thread to form a plurality of cutting edges at the positioning thread at different elevations, and an arc top located at the top side thereof, the ratio between the diameter of said implant root and the number of said spiral grooves being in the range of 1.2˜2.0.
