Rehabilitation of a compromised dentition in individuals with parafunction and excessive masticatory forces is difficult to manage long term. This patient example illustrates an expedited treatment approach to replace and restore the missing and deteriorated dentition. A plan was developed to cope with this clinical status and future requirements. The maxilla was treated with 10 endosseous implants, which included 2 in the pterygomaxillary region and two in the zygoma. The mandibular arch was treated with 7 endosseus implants. The definitive screw-retained prostheses consisted of maxillary porcelain-fused-to-metal and mandibular acrylic resin veneer of a cast metal framework. The patient has been followed for seven years. Prosthodontic complications have been limited to acrylic resin veneer fractures on the mandibular implant-supported prosthesis.
