Abstract
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.
Highlights
The prosthetic rehabilitation of a fully edentulous and atrophic arch with implant-retained dentures requires thorough planning and should provide the correct vertical height and maxillary-mandibular relationship and be esthetically acceptable [1,2,3,4]
In older complete denture wearers, advanced jawbone atrophy simulates the clinical situation of a skeletal class III relationship combined with vertical alveolar bone loss; this condition is classified as pseudoskeletal class III
The analysis and management of the restorative space in edentulous patients with implant overdentures are important for the planning of implant placement and for the design of the denture [16, 19, 20]
