The restoration of the soft palate presents a challenge completely different from that of the hard palate. The mobility of the soft palate tends to interfere with velar extensions. The reduction in size of the soft palate extension to prevent impingement upon the mobile margins of the defect will lead to insufficient oronasal separation during functional activities. The solution is to construct a specially designed prosthesis to attain the maximum utilization of the remaining structures and their motility. Although each pharyngeal extension is different in shape, they give the patient an effective functional mechanism that enhances speech and swallowing.
A classification for partially edentulous maxillectomy patients has been proposed, and a suggested design for each class is discussed. A simplified approach to the planning of resective surgery and a guide for the design of the maxillary obturator prosthesis have been presented.
A classification for partially edentulous maxillectomy dental arches is proposed. This classification is based on the frequency of occurrence of maxillary defects in a population of 123 patients.

This article presents a simple procedure for the construction of facial prosthesis. The use of a split mold lined by silicone 382 is recommended. Pertinent information concerning impression making, sculpturing, coloring, and processing to insure esthetically and functionally accepted prostheses is presented.
This report concerns 14 patients who were treated by use of immediate intermaxillary fixation after segmental resection of the mandible to eradicate cancerous lesions. Mandibular resection usually produces problems in surgical and prosthetic reconstruction. The use of intermaxillary fixation during the first 6 postoperative weeks will reduce the degree of deviation. In mandibular resection for edentulous patients, the original dentures were used postoperatively with slight modification or no modification at all. With fixation and encouragement of early functional movement of the mandible, the dentulous patients showed a lesser degree of deviation. Some of the patients of the latter group used guide flange prostheses during the postoperative period to return the mandible to the centric position. Edentulous patients who deviated slightly were fitted with a maxillary ramp which guided the mandibular segment, after the initial contact, into the proper centric relation.
