摘要： A screw type dental implant system (1), having a dental implant fixture (2), a multifunctional component (3) and an abutment screw (4). The screw shape dental implant fixture has an external surface having buttress threads on the body and micro threads at the collar. This combination provides the advantages of: improved biomechanics at the implant abutment interface, self-tapping nature to the implant, and minimizing the stresses at the crest of the bone leading to decrease resorption of crestal bone. The multifunctional component serves the purposes of implant mount, impression analog and final abutment and has a single prosthetic platform so one component is compatible with different implant dimensions, which minimizes the inventory needed for the implant system and allows easy handling of the system. The multifunctional component also has an external concave transmucosal portion for enhancing the emergence profile and internal threads for securing the abutment screw.
