Simultaneous Upper and Lower Jaw Extractions, Autogenous Bone Augmentation and Temporary Implant Placement with Immediate Loading

Aims: We expanded the known technique for simultaneously augmenting an atrophic maxilla and placement of immediate provisional implants (IPI), followed by immediate loading by performing surgery in both jaws simultaneously. Feasibility of this new technique, implant survival and success were evaluated as well as prosthetic success. Materials and Methods: All patients undergoing simultaneous bone grafting and IPI placement with immediate loading at our institute between the 1st of June 2016 and the 30th of May 2018 were included and followed up for at least one year postoperatively. Results: 3 patients were followed for a mean period of 25.67 months (20 - 29 months). 33 IPIs were placed. All were immobile at second stage surgery without signs of infection. No provisional bridges were lost and no infections were noted. After second stage surgery, none of these 36 final dental implants were lost. There was some bone loss at one implant. In all patients, good functional and aesthetic results were obtained without any unforeseen complications. This renders the implant survival at 100% and the success rate at 97%. Conclusion: The technique is complex due to the intricate step-by-step process that is required and depends on a dedicated team to ensure a proper workflow. When performed correctly, the protocol shows good and predictable results.

Search of Biomarker in the Oral Rehabilitation

Are there any ways to analyze objectively if any good changes happen to the bodies for the patients with acquired edentulous by getting a treatment to recover occlusion? In this study, we focused on interleukin 6 (IL-6) as inflammatory cytokine, cortisol known as a stress related substance and secretory immune globulin A (SIgA) related to immune reaction, and chose 14 patients who had occlusion reconstructed by the immediately loaded dental implants because occlusion contact with maxillary and mandibular dentition was lost caused by edentulous jaws or maxillary and mandibular teeth crossing each other and their jaw position and central occlusion position could not settle, and verified the relationship with changes of patients’ physical and mental states during the 6 months of the treatment and the effect of the immediately loaded implants treatment by using saliva which was non-invasive and easy to sample in biomarkers in saliva. Moreover for female subjects, the changes of facial color tones were measured by using Robo Skin Analyz-er?, a digital image analyzer, to measure the condition of their skin. In conclusion, the positive correlation between the amount of IL-6 and cortisol was not admitted. However, it was admitted that IL-6 tended to increase when a systemic change which interrupted curing such as the interruption of fusion of the implant and the bone was observed even though the patient did not notice any particular symptoms and cortisol tended to increase when the patient noticed discomfort and mentioned any events under stress on his or her medical record. Moreover with the skin color analysis by Robo Skin Analyzer?, the possibility that the occlusion treatment by the immediate implant had an effect on physical and psychological health promotion through the acquisition of the masticatory function and the aesthetic recovery was indicated.
