Procedure

Line-Angle Axxess - LA Axxess Diamond Bur p/n 815-1415

1. Using a surgical length round carbide bur, enter the pulp chamber. Do not attempt to rough out the access cavity preparation with the round bur.

2. Once the chamber is found, replace the round bur with the LA Axxess Diamond Bur. With water spray, place the spinning LA Axxess Diamond Bur into the pulp chamber until you feel resistance. Tip the bur up to a point just shy of the incisal edge.

3. Introduce the bur deeper into the chamber or canal while tipping the bur back into the center of the cingulum region.

4. The bur is now able to cut deeper into the canal and establish ideal straight-line access.

LA AXXESS DIAMOND BUR PROCEDURES

Anterior teeth: Resistance occurs when the pilot tip contacts the buccal surface of the pulp chamber or canal space. Tip the bur up just shy of the incisal edge, and then introduce deeper into the chamber or canal. After the bur is tipped further back into the center of the cingulum region, make a deeper cut into the canal.

Bicuspids: Insert the bur into the pulp chamber and each canal orifice. Tip it out to the working cusp (1-2 mm shy of the idling cusp) for an idealline extension.

Molars: Insert bur into the pulp chamber until it contacts the chamber floor. At that point, tip the bur to match the mesial tooth surface angle. Rotate the bur in a circumferential motion until the pilot tip is felt contacting the pulp chamber’s lateral walls. Finish the cavity prep after the line angles are serially extended to their ideal positions (to the working cusps and 1-2 mm shy of the idling cusps). Accomplish this by angling the bur until its pilot tip drops into each canal orifice, tipping it to the desired extension point, and circumferentially moving the spinning bur around the pilot tip.

LA Axxess Stainless Steel Burs (LASS) may be used as Gates Glidden replacements in a slow-speed handpiece at 5,000-20,000 rpm. Use these instruments for removing dentin without affecting the enamel.

LA Axxess Stainless Steel Bur Procedure

1. Insert the appropriately sized line-angle instrument into an initially accessed tooth. #1LASS for small canals #2LASS for medium canals #3LASS for large canals

2. Tip the instrument up (5,000-20,000 rpm) just short of the incisal edge or cusp tip.

3. In straight canals, push the spinning instrument into the canal to resistance.

4. Finally, tip the instrument toward the cingulum to remove the lingual-dentinal triangle.

5. The completed preparation has no cervically positioned curvature, allowing predictable straight-line access into canals. When line-angle instruments are used in straight canal forms, they can quickly cut the coronal half just short of shape.
