Abstract
Patients: A 72-year-old male patient visited our hospital with a chief complaint of inadaptation and desorption of maxillary removable complete denture. Intraoral views suggested that the patient had strong bite force of grinding-type habitual mastically movement path. A fixed-implant superstructure was placed for the totally edentulous maxilla, and a metal-based denture for the mandible. During a 4-year follow-up, the prognosis has been excellent.
Discussion: Occlusal support based on the fixed-implant superstructure and the metal-base removable denture contributed to the improvement of tooth grinding and instability of the prosthesis.
Conclusion: Osseointegrated implant therapy with a fixed superstructure provided a good prognosis for a case of Eichner classification C2 with the tooth grinding habit.
