Abstract
A sinus dental implant includes a main body, an external thread, and a plurality of spiral cutting flutes. The main body has opposite connection end and drilling end. The drilling end has a centered recess surrounded by a drilling zone and communicable with the spiral cutting flutes. The external thread and the spiral cutting flutes are extended in two different spiral directions. The drilling zone is divided by the spiral cutting flutes into a plurality of drilling segments, each of which has two sides located at different heights to thereby include a lower and an upper drilling portion. When the sinus dental implant is implanted into an alveolar hole to contact with a bottom thereof, the lower drilling portions at the drilling end cut the bottom of the alveolar hole slowly, so that the sinus dental implant can drill further in the alveolar hole instead of idling therein.
