Abstract
A convenient dental tray spacer for use in forming a thin reservoir space between teeth and a dental tray, during tray fabrication. Shim (10) segments are connected by small links (12) to form a spacer (16). The lengths of the links are readily variable. Retention to the teeth is provided by adhesive on rear adhesive surfaces (22). Alternatively, an elastic loop (24) can retain a spacer (16'). Spacer (16), or spacer (16'), remain on the teeth while the dental tray is formed, and then is pulled free from inside the formed dental trays.
Claims13
A preformed dental tray spacer means for shimming moldable dental tray material a predetermined distance from surfaces of teeth of a dental arch, or models thereof, comprising a flat, unitary strip of a deformable material substantially elongate in a longitudinal direction and adaptable for rapid shaping and mounting on said surfaces of teeth, or models thereof, said unitary strip comprising a plurality of tooth shim elements connected to each other by means of links, said tooth shim elements having a circumference in the plane of the unitary strip, each said tooth shim element being comformable overlying surface contours of a tooth, said links being substantially elongate, a portion of said links being substantially elongate in the longitudinal direction of said unitary strip, said links having a sufficient length such that adjacent said tooth shim elements are mountable on adjacent said surfaces of teeth, wherein said circumference of said tooth shim elements is substantially greater than the width of said links.

A preformed dental tray spacer means for shimming dental tray material a predetermined distance from preferred surfaces of dental arch model teeth, comprising a plurality of tooth shim elements connected by links of variable length, said links comprised of elastic material, wherein one said link is of sufficient length to stretchingly encompass the circumference of a dental model, such that said tooth shim elements are retainably pulled against said surfaces of said teeth;
- wherein remaining said links stretch sufficiently to permit rapid positioning of said shims against said surfaces of said teeth.
