Direct answer: Gold Cura Straight Fissure Diamond Burs FG are straight flat-end cylinder burs for preparing straight or near-parallel walls, proximal boxes, flat terminal areas and controlled gross reduction. Choose SF-11, SF-12, SF-13, SF-21, SF-22, SF-31 or SF-41. Each order contains 5 identical burs of the selected code.

Straight Fissure Diamond Burs: Key Facts

Shape	Straight flat-end cylinder / straight fissure
Available codes	SF-11, SF-12, SF-13, SF-21, SF-22, SF-31 and SF-41
Typical applications	Straight-wall preparation, proximal boxes, flat floors or terminal areas, shoulder-style reduction and gross contouring
Shank	FG / friction grip
Pack size	5 identical burs of the selected SF code

When to Use Each SF Bur

Comparable catalogues group SF-11 to SF-13 as longer heads of progressively greater width; SF-21 and SF-22 as shorter medium and wider profiles; and SF-31 and SF-41 as compact precision options. Exact Gold Cura dimensions should be confirmed from the product specification.

Code	Relative profile	When to use it
SF-11	Narrow long cylinder	Conservative long axial walls, narrow boxes, straight-wall preparation and controlled shoulder development.
SF-12	Medium long cylinder	General-purpose crown, box and flat-wall preparation with moderate width and extended side contact.
SF-13	Wide long cylinder	Broader axial reduction, larger posterior boxes and wide flat terminal surfaces.
SF-21	Medium shorter cylinder	Shorter axial walls, routine inlay or box preparation and controlled reduction where a long head is unnecessary.
SF-22	Wide shorter cylinder	Broad but shallow or shorter preparations, larger proximal boxes and posterior flat-surface reduction.
SF-31	Narrow compact cylinder	Small cavities, localised wall refinement and conservative precision preparation.
SF-41	Smallest compact profile	Very localised cutting, fine access, small rest or slot preparation and minimal flat-ended refinement.

Simple selection rule: SF-11 to SF-13 are long profiles from narrow to wide; SF-21 and SF-22 are shorter; SF-31 and SF-41 are compact precision choices.

Straight Fissure vs Tapered Fissure

Shape	Wall form	Typical selection
Straight fissure / SF	Straight or near-parallel	Boxes, flat floors and straight axial walls
Tapered fissure / TF	Tapered or convergent	Crown walls, inlays and flat-ended tapered preparations
Straight round-end / SR	Straight with rounded internal transition	Parallel walls without a sharp flat terminal angle

How to Choose and Use an SF Bur

Select length first. Use long, short or compact profiles according to wall height and access.
Select the smallest suitable width. Avoid unnecessary tooth removal.
Maintain the planned path of insertion. A straight cylinder can create unwanted parallelism or undercut if tilted.
Use light pressure, water cooling and intermittent contact.
Switch to a fine bur for final margin refinement when required.
