Abstract:
Patients who have undergone a bilateral maxillectomy are particularly difficult to rehabilitate prosthetically by using a conventional obturator prosthesis, mainly because of the extensive loss of tissues for retention and support. In these situations, adapting to existing undercuts within the defect is essential. Traditional impression techniques capture certain anatomic landmarks but may fall short of the needed sinus undercuts. This article describes an alternative impression technique for capturing 3 opposing undercuts to help retain, support, and stabilize a hollow 1-piece obturator prosthesis for a patient who underwent a total maxillectomy.
