Using the "One Shot" Concept for Immediate Loading Implant Protocol in Edentulous Patient Rehabilitation with a Fixed Prosthesis: A 6-Year Follow-Up

Immediate Loading Implant-Supported Fixed Full-Arch Rehabilitation Using a New Clinical Decision-Support System: A Case Series

Background Implant-supported full-arch rehabilitation is an effective treatment for edentulous patients. It restores mastication, facial aesthetics, and psychological well-being. Patient-related outcome measures support the validity of this approach, emphasizing the importance of effective prosthodontic interventions for this patient population. This study aims to present a case series for fixed implant-supported full-arch rehabilitation using the new Carames classification (CC). Methods A total of seven patients with generalized periodontitis or non-restorable multiple teeth were indicated for extraction and replacement with a fixed full-arch implant-supported prosthesis. According to the Carames classification, most cases were categorized as CCI or CCII classes for both the upper and lower jaws. Before the surgery, screw-retained provisional complete dentures were constructed and adjusted for the vertical occlusal dimension and smile lines. After the extractions, 70 implants were immediately placed in one or both arches for the seven patients, followed by bone grafts with the dual-zone grafting technique. Multi-unit abutments were then placed and welded to a metal bar for stable fixation. The provisional denture was fitted snugly over the metal bar for immediate functional loading. After three months of healing, it was used as a biocopy to fabricate the final prosthesis. The implant loss and the peri-implant marginal tissue health status were assessed annually for three years. Statistical analysis compared the marginal bone loss as a change from the baseline over the year. Results No implant or prosthesis loss was reported over the three years. Peri-implant marginal tissue health showed promising results without bleeding and suppuration on probing and probing depths between 3 and 3.5 millimeters. Marginal bone loss was minimal over the three years, with some cases showing bone gain. Conclusion Using the Carames classification as a clinical decision support system in implant-supported full-arch rehabilitation showed promising results in peri-implant tissue health and no implant loss during three years of follow-up. The implant placement and prosthesis fabrication protocol in this study could be valuable for further research.

Full Digital Workflow for Prosthetic Full-Arch Immediate Loading Rehabilitation Using OT-Bridge System: A Case Report

Nowadays, digital technologies have brought very important advancements in clinical prosthetic dentistry. However, a full digital workflow is still considered to be challenging in the management of full-arch implant cases with immediate prosthetic loading. The aim of this case report is to show a full-digital workflow for the fabrication of an implant-prosthetic fixed provisional prosthesis for immediate loading on seven implants in the upper maxilla. The static guided implant surgery and the OT Bridge prosthetic system were used to rehabilitate the patient. In this way, the combination of a well-known surgical technique with a peculiar prosthetic system that allows for a certain degree of tolerance resulted in it being useful for full-arch immediate loading. Future research and studies are necessary to prove the reliability of this full-digital protocol.
