Objectives:
Patients undergoing hemimandibulectomy suffer from mandibular deviation. The purpose of this article is to describe a new therapeutic possibility for the prosthetic management of these patients using only one device both for physiotherapy and eating.
Methods:
A 56-year-old man's pre-existing mandibular removable partial prosthesis was modified to use as a partial prosthesis as a device to correct mandibular deviation. In fact, two precision attachments patrix were inserted into buccal surface of partial prosthesis base and corresponding matrix were inserted into a transparent acrylic resin guide-flange.
Results:
In this way the patient can use only one prosthesis both for physiotherapy and eating simply inserting and removing the guide flange. The transparent resin employ is important for the day by day use.
Conclusion:
This technique permits to use only one device both for mechanical correction of mandibular deviation and masticatory function while literature shows that two different devices are usually used in patients with mandibular deviation to satisfy both these functions.
