Anatomically proportioned to the first and second molars, the upper and lower Busa Molar Bands provide a precise fit. The occlusal edge is perfectly adapted to the tooth avoiding occlusal interference. The interproximal walls are flat, thus, easy to insert into the particular molar. The Busa Molar Bands are permanently marked by laser and are available in kits of 27 different sizes or can be ordered as refills.
