title: Management of biomechanical complication of implant-supported restoration of a patient with combination syndrome: a case report.
abstract: Combination syndrome (CS) is a pathologic condition of the stomatognathic system characterized by an edentulous maxilla with an atrophic anterior ridge, maxillary papillary hyperplasia, hypertrophic maxillary tuberosities, super-erupted mandibular anterior teeth, as well as atrophic mandibular posterior ridges. This condition can present a challenging situation to the clinician who needs to assemble evidence from all aspects of dentistry to formulate an appropriate treatment plan. One of the possible treatment choices for the fully edentulous patient with a CS is a full-arch implant-supported reconstruction for both maxilla and mandible. The purpose of this study is to illustrate and discuss a biomechanical complication-fractured maxillary meso bar in a patient with CS, and to present a description of how this complex case was corrected and successfully completed. The analysis of implant-supported and implant-retained full arch restorations in edentulous patients with CS is presented and treatment recommendations are given. A necessity of individualized approach for every implant reconstruction case, especially complicated with a CS, is suggested.
