    Rehabilitation of an Extremely Edentulous Atrophic Maxilla with a Pseudoskeletal Class III Relationship
    (2019) Yoon, Tae Ho; Abuzayda, Moosa
    Summary: The skeletal class III relationship presents complex dentoalveolar problems, requiring multidisciplinary treatment. In edentulous people, severe atrophy of the jawbone simulates the clinical appearance of a skeletal class III relationship (pseudoskeletal class III), which presents major problems for rehabilitation. This article describes the rehabilitation of a 67-year-old patient with a pseudoskeletal class III relationship. The mandible was restored with two implant supported bar-retained overdentures using clips for retention. The extremely atrophic maxilla was restored with a combination of sinus augmentation, implant placement, and classic prosthodontic treatment using an electroformed mesostructured overdenture with swivel lock attachments on an implant-supported bar. By performing minimal augmentative and implant surgeries and using the possibilities and advantages of classic prosthetic dentistry, the clinical situation described here could be managed and the atrophic maxilla could be rehabilitated.

    The use of a customized mounting guide for Implant-Prosthetic Restoration of the Fully Edentulous Arch
    (2017) Sotiropoulos, Evangelos; Yoon, Tae Ho; Abuzayda, Moosa
    Abstract: Reconstruction of fully edentulous arches with implant-retained dentures requires thorough planning and precise registration of the interocclusal relationship, to achieve a successful treatment outcome. This technical report describes three representative approaches from a cohort of 89 fully edentulous arches in 69 patients who were treated with the described mounting guide technique. A technique of using a duplicated denture as a guide is described, which allows for the accurate transfer of the occlusal relationship and vertical dimensions, while facilitating the full-arch restoration process with implantretained fi xed or removable dentures and reducing the number of required in-office sessions.
