6.3) MEtaL REStORatIONS
he working end of the Transmetal bur is used to initially cut a small window through metal. Optimally use the
lateral side of this instrument to decrease heat, reduce vibration and improve efficient performance.
6.4) REMOVING tOOtH StRuctuRE, caRIES OR SMaLLER SIZED REStORatIONS
In general, use the long length, smaller-sized carbide round bur to access anterior and bicuspid teeth;
whereas, use the long length, larger-sized carbide round bur to access molar teeth. These longer length
burs serve to move the head of the handpiece further away from the occlusal table providing an improved
line of sight. Use these burs with a light brush-cutting action to move progressively deeper into the clinical
crown of a tooth, enter the pulp chamber, then remove all unsupported dentin overlying the pulpal roof.
6.5) EXPaNDING tHE accESS PREPaRatION
Select the tapered diamond or the Endo Z to expand the access cavity and finish the axial walls so they
smoothly diverge from the pulpal floor to the occlusal cavo surface.
Please note: the tapered diamond has a parabolic working end that enables you, at slower rpm, to precisely
sand away and selectively remove dentin to uncover hidden grooves and orifices, whereas the endo-Z has a
non working end that enables you to preserve the original pulpal floor morphology without perforation risks.
6.6) FLaRING aND INtENtIONaLLY RELOcatING tHE ORIFIcE
Use the X-Gates with a brush-cutting action, at 500-800 rpm, to flare and blend the orifice into the lateral
axial walls. Importantly, the shaft of the X-Gates should be arced so the cutting flutes selectively cut dentin
on the outstroke and to intentionally relocate the canal away from an external root concavity.
