Surgical and prosthetic reconsiderations in patients with maxillectomy

The purpose of this study was to establish and evaluate new possibilities for rehabilitation of patients with obturator prosthesis who had undergone partial or total maxillectomy because of tumour ablation surgery. Eleven patients with maxillary defects were reconstructed with a computer-aided design/computer-aided manufacturing designed prosthesis. Missing retention was gained by inserting implants in the remaining bone, so that an expansion of the surgical defect to gain further retention could be avoided. All patients were treated successfully according to the previously described treatment plan. The Obturator Functioning Scale (OFS) of the Memorial Sloan-Kettering Cancer Centre was applied to evaluate the functional quality of the obturator prosthesis and patient's satisfaction. It showed good results in all fields of functional outcome and social acceptance.
