Prosthodontic rehabilitation in the maxilla following treatment of oral cancer.

This is the second in a two-part series on oral cancer. Part 1 focused on the surgical aspects of treatment and morbidity associated with oral cancer. In this article aspects of prosthodontic management of patients with maxillary tumours are considered, with emphasis on promoting optimal rehabilitation.

Clinical assessment of chewing function of obturator prosthesis wearers by objective measurement of masticatory performance and maximum occlusal force.

PURPOSE: Eating, which includes chewing and swallowing, is an oral function that influences quality of life. Though the swallowing ability of maxillectomy patients was reported in our previous study, the chewing function has not been fully reported to date. Thus, the purpose of this study was to evaluate the chewing function of obturator prosthesis wearers by measurement of masticatory performance and occlusal force. The relationship of these 2 measurements was also investigated. MATERIALS AND METHODS: Twenty maxillofacial obturator prosthesis wearers undergoing periodic checkup at the maxillofacial rehabilitation clinic in Kyushu University Hospital were recruited for this study. Additionally, 20 young, healthy individuals were recruited as controls. Data on masticatory performance, which was measured by a sieve method using hydrocolloid material, and maximum occlusal force, which was measured by the Dental Prescale System (Fuji Film), were obtained for each participant. RESULTS: The mean of masticatory performance was 2.6 (SD 1.2) on a 1.40-mm mesh. There was no significant difference in masticatory performance between the patient group and the controls. The mean maximum occlusal force of the patient group was 625.9 N (SD 299.1 N), which was significantly lower than that of the control group. There was no significant correlation between masticatory performance and maximum occlusal force for the patient group in this study (P = .3726). CONCLUSION: Masticatory performance of obturator prosthesis wearers with dentate or partially edentulous maxillae was not different from that of young, healthy individuals, though maximum occlusal force of these patients was lower than that of controls.

Urethane-lined silicone facial prostheses.

After testing a variety of materials to line the tissue-fitting surface of silicone prostheses in an attempt to render them adheophilic, tear-resistant, wettable, smooth, and resistant to fungal growth, a vacuum adaptable thermoplastic prefabricated thin urethane film was found to be most effective. A technique is described for fabricating a silicone prosthesis with such a lining.

Prosthodontic guidelines for surgical reconstruction of the maxilla: a classification system of defects.

Surgical reconstruction of maxillectomy defects has been described as an alternative to prosthetic rehabilitation to close the oral cavity. Advancements in microvascular surgical techniques require comprehensive treatment planning guidelines for functional rehabilitation. This retrospective study evaluated acquired maxillectomy defects after surgical reconstruction and/or prosthodontic rehabilitation in an attempt to establish surgical and prosthodontic guidelines that could be organized into a classification system. Forty-seven consecutive patient treatments of palatomaxillary reconstruction at a single facility, The Mount Sinai Medical Center (New York, N.Y.), were reviewed. All patients were rehabilitated with a tissue-borne obturator, a local advancement flap, a fasciocutaneous free flap, or a vascularized bone-containing free flap. Palatomaxillary defects were divided into 3 major classes and 2 subclasses. The aim of this defect-oriented classification system was to organize and define the complex nature of the restorative decision-making process for the maxillectomy patient.

[Dento-stomato-facial rehabilitation of young patients. Practical alternatives].

The design conception and the technological achievement of every gnato-prosthetic device are conditioned by a minute evaluation of the biological and morphological individualities of each case, the social level of the patient, corroborated with the technological supply. In our study we evaluated different modalities of dento-stomato-facial rehabilitation of young patients with partially reduced maxillary or mandibular dentition. The study was carried out on a group of 12 young patients, 5 males and 7 females, aged between 16-24 years, who presented at the clinic for the treatment of complex functional disorders that occurred as a consequence of the dentition. The fixed mixed gnatoprosthetic therapy for the young patients and teenagers has to be adapted to the surveyed clinical individuality. The success of the therapy is assured by the accurate application of the gnatoprosthetic principles, the accurate achievement of the technological steps, the use of compatible biomaterials according to the dento-stomato-facial features of this age category.

A denture replication technique following partial maxillectomy: a case report.

A variety of problems faces the prosthodontist attempting reconstruction of maxillary defects. There are various treatment options for patients requiring a partial maxillectomy and an obturator prosthesis. Reduced adaptability makes it difficult for the patient to learn to use a new appliance, unless existing skills can be employed. It is therefore helpful to reproduce familiar features of a patient's existing obturator, especially if this has been used successfully over a transition period.
