摘要： The invention provides a screw type dental implant system (1), comprising three components namely-Dental implant fixture (2), Multifunctional component (3) and the Abutment screw (4). The invention includes screw shape dental implant fixture with external surface having Buttress threads on the body and micro threads at the collar of particular dimensions. This combination provides advantages of improved biomechanics at the implant abutment interface, self-tapping nature to the implant and minimizes the stresses at the crest of the bone leading to decrease resorption of crestal bone during the implant functioning thus ensuring long-term implant stability. The multifunctional component of the system serves the purpose of implant mount, impression analog and final abutment. In addition the multifunctional component has a single prosthetic platform so one component is compatible with different implant dimensions. Thus the multifunctional component minimizes the inventory needed for the implant system and allows easy handling of the system. The implant abutment connection has internal type interface with medialized implant abutment junction allowing better maintenance of crestal bone level. The abutment has an external concave transmucosal portion for enhancing the emergence profile and additional internal threads for securing the loosened abutment screw. The abutment screw has long internal channel, which can be adjusted according the height of abutment without loosing its fastening property.
