Abstract

A pair of dental burs for shaping mandibular teeth into the proper sloped configuration for lingual occlusion or denture teeth. The first bur is provided with a non-cutting central portion that is flanked by two slightly angled cutting surfaces, and the second bur is provided with a cutting central portion that is flanked by two slightly angled non-cutting surfaces. The angulation of the two cutting surfaces on the first bur may or may not match each other on a given set of burs, and the angulation of the two non-cutting surfaces on the second bur may or may not match each other on a given set of burs, but the angles of the cutting surfaces on the first bur match the angles of the non-cuffing surfaces on the second bur. The burs are used sequentially; i.e. the first bur is used first and the second bur is used second, to achieve the desired slope and center floss for the mandibular teeth without cutting too deeply.

Dependent claims

Lingual occlusal burs for shaping denture teeth comprising:

a first bur provided with a first shank, a proximal end of said first shank for removable attachment to a drill and an opposite distal end of said first shank, a proximal end of a first bur head secured to said distal end of the first shank, a non-cutting central portion provided approximately midway between said proximal end of the first bur head and an opposite distal end of said first bur head, both said proximal end and said distal end of said first bur head provided with cutting surfaces, and each said cutting surface provided at an acute angle to a line parallel to a longitudinal axis of the first bur, and
a second matching bur provided with a second shank, a proximal end of said second shank for removable attachment to a drill and an opposite distal end of said second shank, a proximal end of a second bur head secured to said distal end of the second shank, a cutting central portion provided approximately midway between said proximal end of the second bur head and an opposite distal end of said second bur head, both said proximal end and said distal end of said second bur head provided with non-cutting surfaces, and each said non-cutting surface provided at an acute angle to a line parallel to a longitudinal axis of the first bur.
