Popis: | Maxillofacial prosthetic patients present the same major problems as other partial denture patients. That problem is the control of stress between the resilient denture base element and the more immobile teeth. The maxillofacial prosthetic patient has an added problem because the basal seat area on which the denture base rests usually is made up, in part, of grafted bone, and often has grafted skin instead of the mucous membrane covering this bone. This abnormal foundation allows more movement of the base in function than severely resorbed residual alveolar ridges. Also, the restoration of the lost parts is usually heavy and bulky, and this adds to the load on the remaining teeth. The remaining teeth in these patients are extremely valuable to them. Because of the abnormality, they would have more difficulty if they were to be forced into wearing a complete denture. When stress-breaking is the major consideration, the combination clasp does the most effective job. A double or split-bar type of stress-breaker is very effective where the abutment teeth are all posterior to the denture base. This design prevents rotation about the anterior rests. The truss-bar retainer is used where a large number of healthy teeth remain and maxium retention is needed to support an obturator or other large appliance. |
