Abstract
A sequence of canal instruments for performing an endodontic operating protocol uses a sequence of several instruments, for example, three such instruments with three cutting blades. The instruments have a progressive conicity, for example, 6%, 4% and 2%, and each instrument has an identical progressive pitch. The pitch further increases progressively from instrument to instrument as a function of the conicity of each instrument.
Claims6
A sequence of canal instruments for performing an endodontic operating protocol comprising a plurality of instruments adapted for use in a defined sequence, wherein each of the instruments has a plurality of cutting blades, wherein the sequence of instruments have progressive conicities from instrument to instrument in the sequence, wherein the sequence of instruments have progressive pitches including a defined progression and a defined initial pitch, wherein the progression of each instrument is identical to the progression of the other instruments in the sequence, and wherein the initial pitch of the instruments in the sequence of instruments increases progressively as a function of the conicities of the instruments in the sequence and varies in increasing proportion.
