The Application of Maxillary Orthognathic Surgery and Implant Supported Fixed Dental Prostheses to Reconstruct a Patient with Skeletal Class III Jaw Relationship
摘要
In patients with a maxillary partially edentulous ridge and Class III jaw relationship, it is difficult to establish a clinical outcome with adequate esthetics and function by using implant-supported fixed dental prostheses (FDPS). This report presents the case of a female patient with a skeletal Class III jaw relationship whose maxillary teeth, other than the third molars, had all been extracted because of advanced chronic periodontitis. Because the patient did not want to wear removable prostheses, implant-supported FDPS were planned for her. An interdisciplinary treatment approach combining maxillary orthognathic surgery (i.e., Le Fort I osteotomy) for maxilla advancement with subsequent iliac onlay bone grafting and computer-guided flapless implant surgery and reconstruction with modified monolithic zirconia implant-supported FDPS was used to treat the patient. The pre-surgical, surgical, laboratory, and prosthetic stages and 18-month follow-up outcomes are described, with the outcomes indicating complete arch rehabilitation. Finally, we met the treatment goals of rehabilitation of the patient's chewing function and a satisfactory appearance when smiling.
