Abstract
An expandable dental tray apparatus and method are provided, the apparatus having a center section and two side sections interconnected by deformation zones or hinges. The apparatus in a retracted configuration may be inserted into a mouth, then adjusted into one or more expanded configurations. Locking mechanisms maintain the dental tray in the desired expanded configuration. The side sections may be easily replaced with alternatively sized side sections prior to use.
Claims20
A dental impression tray comprising:
- a center section centered about a longitudinal centerplane, said center section comprising a central base plate, a central outer wall, and a central inner wall concavely curved and terminating at two central end portions;
- two side sections, each said side section comprising a side base plate, a side outer wall, and a side inner wall curvedly extending from a side proximal end portion towards a more substantially straight side distal end portion;
- two deformation zones, each said deformation zone interconnecting said center section at one of said central end portions and one of said side sections at said side proximal end portion, each said deformation zone for adjusting orientation of one of said side sections relative to orientation of said center section.
A dental impression tray comprising:
- a center section centered about a longitudinal centerplane, said center section comprising two first hinge ports and the combination of a central base plate, a central outer wall, and a central inner wall concavely curved and terminating at two central end portions;
- two side sections, each said side section comprising a second hinge port and the combination of a side base plate, a side outer wall, and a side inner wall curvedly extending from a side proximal end portion towards a more substantially straight side distal end portion;
- two hinges, each said hinge interconnecting said center section at one of said first hinge ports with one of said side sections at one of said second hinge ports, wherein said center section and one of said side sections is rotatable about one of said hinges.
