Abstract
An intra-oral device comprising an upper splint, a lower splint and a pair of lateral connecting rods. Each connecting rod has a first rod end that connects to the lower splint and a second rod end that connects to the upper splint. The connecting rods are configured to maintain the mandible in an advanced position relative to the maxilla. The upper splint includes at least one upper gutter portion that retains the upper splint on the maxilla. The lower splint includes at least one lower gutter portion that retains the lower splint on the mandible. The thickness of the at least one upper gutter portion and/or the at least one lower gutter portion may vary across the profile of the teeth.
Claims10
Method of designing an intra-oral device including the steps of:
- obtaining an electronic image of a patient's dental arch including the teeth on the maxilla and the teeth on the mandible;
- processing the received image to:
- determine a retention portion on a crown region of at least a portion of one or more teeth;
- calculate a retention profile based on the determined retention portion to spread the load of retention across the portion of teeth available for gripping;
- and
- design an intra-oral device having an upper splint and a lower splint and a pair of lateral connecting rods connecting the upper and lower splints,
- wherein at least one of the upper splint and the lower splint includes the calculated retention profile.
