Implant-supported maxillary full-arch fixed prosthesis opposing mandibular natural dentition: A clinical report / 대한치과보철학회지

ABSTRACT

When an implant-supported maxillary full-arch fixed prosthesis is planned for patients with the horizontal and vertical bone resorption induced by periodontal disease, it is necessary to consider the masticatory function, esthetics and phonetics when placing implants. For this reason, thorough clinical and radiological diagnosis is necessary. Extensive bone and soft tissue grafting may be required as well. Since there is no clear guideline for proper number of implants, segment or splinting of substructure and method of retaining prosthesis, these should be considered during diagnostic process. This clinical report describes a patient who has experienced several tooth extractions and periodontal treatment due to severe periodontitis on maxilla and mandible. With bone and soft tissue graft before dental implant placement, the patient have satisfactory result in esthetic and functional aspect with the implant-supported maxillary full-arch fixed prosthesis opposing mandibular natural dentition.
