ABSTRACT:
A dental implant for fixing a dental prosthesis comprises a main body implantable in a maxilla and having a central hole formed so that a bolt can pass through the central hole for fixing a dental prosthesis, the main body also having a protuberance with a polygonal cross-section, and a pre-prosthetic collar having a central hole through which the bolt can pass and connectable with the main body, the pre-prosthetic collar having an internal thread, and the protuberance having external edges provided with notches which form a threading for engaging with the internal thread of the pre-prosthetic collar, so that the pre-prosthetic collar is fitted onto the protuberance by screwing without need for additional bolts.
