In the following case presentation, we want to showhowshortimplantshavebeensuccessfullyused to restore severely atrophic mandibles without the use of difficult bone augmentation procedures and complicated prosthetic suprastructures in the past decade. _Material and methods Bicon Dental implants (Bicon LLC, Boston, MA, USA) were used for the reconstruction of the case, combined with a CAD/CAM fiber reinforced resin framework (Trinia™) and conventional denture teeth and resin prosthesis. Bicon implants can be charac- terized by their special macro-structure, including a root-shapeddesignwithwidefinscalledplateaus,by aslopingshoulderandbyawellwhichholdstheabut- ment post by means of a Locking Taper connection.1 The plateaus are of particular importance for the biomechanical performance, allowing SHORT® im- plantswithawidediametertobeusedinanyposition in the oral cavity. Their insertion into the osteotomy, which has been prepared using atraumatic drills ro- tating at 50 rpm, is executed by using mechanical pressure.
