Vintage Trubyte Teeth Selection Rim by The Dentist's Supply Company

This is a specialized vintage dental instrument known as a Selection Rim, housed in its original red cardboard box. The set includes a slender, likely stainless steel or chrome-plated metal rim curved to mimic a dental arch, accompanied by a wire mounting tool. These components were used mid-20th century to determine the proper size and form of dental prosthetics by temporarily mounting teeth to the rim for trials in a patient's mouth. The box lid features clear black typography identifying the manufacturer as 'The Dentist's Supply Company' located at '220 West 42nd Street, New York, N. Y.' and states it was 'Made in U. S. A.' The small cardboard box shows signs of vintage wear, including edge softening, minor color loss (rubbing), and light staining consistent with age and storage. The metal components appear well-preserved with a clean, reflective finish and minimal surface oxidation. This piece likely dates from the 1920s to the 1940s, reflecting the industrial precision of early modern dental technology. The craftsmanship is evident in the uniform curve of the rim and the clean bends of the wire applicator.
