Abstract: The ability to achieve predictable results in oral implantology depends on indepth knowledge of all factors affecting bone healing, as well as on implant characteristics and the mechanical forces involved in immediate loading. The success of the immediate loading protocol relies on three main factors: (1) primary stability, which limits micromotion of the implant, (2) secondary biologic stability, resulting in osteogenesis in the peri-implant area, and (3) the control of bone resorption caused by deleterious loading forces that lead to implant instability during healing. Activated platelets play a crucial role in peri-implant healing and the use of Plasma Rich in Growth Factors (PRGF) in association with immediate implant placement could be a viable therapeutic option for the reabilitation of postextraction sockets. In our case-study, the implants and the abutments were welded with a titanium bar in order to provide predictable fixation and immobility of implants in early stages of bone healing. The implants have been properly integrated at both the bone and gingiva levels allowing the patient to resume both esthetic and masticatory functions from the very day the implants are inserted.

Abstract: This study analyzed immediate implantation and immediate loading of chemical mechanical polished (CMP) and resorbable blast media (RBM) SSIII OSSTEM dental implants histometrically. The 1st, 2nd, 3rd, and 4th mandibular premolars were extracted from five adult dogs. Immediate implantation was performed in the fresh extraction sockets. Each dog received two types of implant: CMP and RBM. The first premolar was submerged, whereas the second, third, and fourth were not submerged. The implants were splinted using acrylic resin and subjected to immediate loading. After 4 months, X-rays were taken and analyzed. The animals were euthanized and processed histologically to obtain non-decalcified sections. Longitudinal ground sections of each implant were made, and histometry was analyzed under light microscopy. No significant difference was found between the control and experimental groups based on immediate loading (p > 0.05) and implant surface (p > 0.05). The implant survival rate and implant-to-bone contact rate after immediate loading were similar to those of submerged implants. The CMP and RBM dental implants did not differ in terms of implant survival rate and implant-to-bone contact rate.
