ABSTRACT:
A dental implant includes a dental implant body which is a cylinder body having a first end and a second end, an asymmetric thread being provided around the dental implant body, an apex lock being formed at the first end for inserting into a sinus of a desired position, and an endomaximum lock being provided at the second end for integrally connected with an abutment through a bolt. The apex lock is a space indented in the first end for enabling new grown bone of the sinus extending into the apex lock to provide a locking mechanism to ensure integration between the dental implant and the bone. The endomaximum lock has a lock cavity having a lock opening at the second end for receiving a root of the abutment therein.
