Abstract
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.
Highlights
The use of endosseous dental implants is a well-established solution for these patients, provided sufficient bone volumes are present for implantation
Augmentation of the alveolar ridge in the edentulous maxilla is performed by buccal plating and/or a bilateral sinus lift procedure
immediate provisional implants (IPI) survival and implant survival were defined as the IPI or implant still being present intraorally without signs of infection or clinical mobility
Summary
Provisional prostheses attribute to an increased resorption of the graft and poor healing due to the exerted pressure on the surgical area [1] [2] To overcome these issues, meet patient’s prosthetic wishes and improve satisfaction rates, Lenssen et al [1] came up with a technique providing a fixed prosthesis immediately postoperatively after augmentation of a severely atrophic maxilla. Meet patient’s prosthetic wishes and improve satisfaction rates, Lenssen et al [1] came up with a technique providing a fixed prosthesis immediately postoperatively after augmentation of a severely atrophic maxilla This treatment method was further developed by Barbier and colleagues from the same institute [3]. To the best of our knowledge, these adaptations have not been previously reported
