A case report of a maxillary denture with obturator prosthesis using multiple Roach clasps

Abstract

Patient: The patient was a 53-year-old male who was referred by a head and neck surgeon for preoperative examination of pleomorphic adenoma extraction. After surgery, he had a defect in his left-side maxillary bone. A maxillary denture with obturator prosthesis using multiple Roach clasps was manufactured. One year and seven months after the denture for defective maxilla was installed, the retainer of the denture was damaged and so the denture was manufactured again.

Discussion: The remanufactured maxillary denture with obturator prosthesis has been used without problems for more than four years. We consider that this design reduces the lateral force which causes harmful stress on the abutment teeth.

Conclusion: The use of multiple Roach clasps as a retainer for the maxillary denture with obturator prosthesis reduced the harmful stress on the abutment teeth and allowed long-term stability.
