A two-phase implant, hexagonal in shape, inserted next to a blade after 20 years. Three different steps: tapping screws, healing screws and, lastly, abutment. Fig. 10a, b_Two-phase ixture. c. Provisional abutment inserted in the second surgical phase. Impression abutment, the successful gingival, cervical remodeling is visible. d. Deinitive crown in intraoral x-ray. contact areas between screws and cortical bone. Our studies highlight in fact how critical these zones are, given that they are subjected to the highest levels of stress. Such a phenomenon is to be considered the main cause of bone/cone reab- sorption, recorded over time in the area (Fig. 13a). In one-piece implants in immediate loading (self-tapping screws and needles), the analyses we carried out highlighted how a part of the ac- tive load on the implant is transferred from the bar to the outer implants. The direct consequenc- es of this transfer, is a reduction in the maximum implants 4_2016 5151
