When to Use Each TR Bur
Comparable catalogues group TR-11 to TR-14 as longer heads of progressively greater width and TR-20, TR-21 and TR-23 as shorter heads from narrow to wide. TR-26 is a compact special profile. Common competitor dimensions must not be treated as confirmed Gold Cura specifications.
| Code | Relative profile | When to use it |
|---|---|---|
| TR-11 | Narrow long round-end | Conservative crown and veneer preparation, narrow axial walls and smaller teeth requiring extended side contact. |
| TR-12 | Medium long round-end | General-purpose crown preparation, routine axial reduction and moderate chamfer development. |
| TR-13 | Wide long round-end | Broader posterior preparation, wider axial reduction and more substantial chamfer margins. |
| TR-14 | Broadest long profile | Large posterior teeth, extensive axial reduction and broad chamfer preparation where a robust head is appropriate. |
| TR-20 | Narrow shorter round-end | Conservative short-wall preparations, localised chamfers and restricted access. |
| TR-21 | Medium shorter round-end | Routine shorter crown or inlay preparation and moderate localised axial reduction. |
| TR-23 | Wide shorter round-end | Broad but shorter posterior preparations and wider localised chamfer development. |
| TR-26 | Compact special round-end | Localised margin refinement, conservative access and precise rounded internal contouring where a standard long head is unnecessary. |
Simple selection rule: TR-11 to TR-14 are long profiles from narrow to broad; TR-20, TR-21 and TR-23 are shorter; TR-26 is the compact precision option.
Taper Round-End vs Taper Flat-End
| Shape | Terminal form | Typical preparation |
|---|---|---|
| TR round-end | Rounded | Chamfer margins and rounded internal transitions |
| TF flat-end | Flat | Shoulder or butt-joint terminal form |
| TC conical point | Pointed | Interproximal access and fine contouring |
How to Select and Use a TR Bur
- Choose the required working-head length.
- Choose the smallest width that creates the planned chamfer or contour.
- Follow the intended path of insertion and preserve rounded internal line angles.
- Use water cooling, light pressure and intermittent contact.
- Use a fine or extra-fine counterpart for final margin refinement when indicated.
