ABSTRACT:
The dental appliance includes a generally elliptical-shaped wire folded about a minor axis to form upper and lower, generally U-shaped sections having front and rearwardly extending leg portions. The leg portions are connected one to the other to enable resilient displacement of the upper and lower sections toward one another. In one form, a clamping element is pivotally secured to each of the upper and lower sections for securing a cotton roll between the element and sections whereby the cotton roll completely envelops the portions of the appliance which would otherwise bear against the soft tissue of the patient's mouth. In a further form, mesh is applied about the wire in lieu of the clamping element to secure a wrapping of flexible material about the wires forming the appliance, also protecting the soft tissues of the patient's mouth from the appliance.
