Abstract
An orthotic device (100) for retaining a patient's mandible in an advanced or protrusive position comprises an intraoral anterior mandibular abutment surface (125) for resisting mandibular retraction by abutting the gingiva covering the mandible and an extramaxillary anterior maxillary abutment surface (115) against which the intraoral anterior mandibular abutment surface (125) is braced. In order to resist rotation of the dental orthotic produced by the interaction of the intraoral anterior mandibular abutment surface and the extramaxillary anterior maxillary abutment surface, the orthotic device is provided with an intraoral posterior maxillary abutment surface (140). The relative positions of the maxillary and/or mandibular abutment surfaces may be adjusted to suit the requirements of the user.
Claims29
A dental orthotic device for retaining a patient's mandible in a protrusive position, the dental orthotic device comprising:
- a convex band-shaped intraoral anterior mandibular abutment surface for resisting mandibular retraction by abutting the patient's gingiva covering the mandible, wherein the intraoral anterior mandibular abutment surface does not encompass the teeth;
- an extramaxillary anterior maxillary abutment surface against which the intraoral anterior mandibular abutment surface is braced by means of the extramaxillary anterior maxillary abutment surface abutting the patient's tissue covering the subnasal maxillary bone;
- an intraoral posterior maxillary abutment surface to resist rotation of the dental orthotic produced by interaction on the patient of the intraoral anterior mandibular abutment surface and the extramaxillary anterior maxillary abutment surface.
A method of retaining a patient's mandible in a protrusive position, the method comprising:
- resisting retraction of the mandible by abutting on the patient's gingiva covering the mandible a convex band-shaped intraoral anterior mandibular abutment surface, which does not encompass the teeth;
- bracing the intraoral anterior mandibular abutment surface against an extramaxillary anterior maxillary abutment surface;
- and
- bracing against rotation produced by the interaction of the intraoral anterior mandibular abutment surface and the extramaxillary anterior maxillary abutment surface, with an intraoral posterior maxillary abutment surface.
