Problem: Hidden Caries
Increased fluoride use has made it difficult to detect fissure caries using explorers and x-rays. A large percentage of suspect fissures have decay present.

Studies have shown that over 90% of pits and fissures with subsurface staining and white decalcification have decay present.

Solution: The Fissurotomy® Bur
The scientifically developed instrument for the conservative diagnosis and treatment of hidden caries.

• Tip of bur is smaller and more conservative than 1/4 round
• Fine carbide tip will not strip quickly like thin diamonds.
• Virtually pain free to the DEJ.... in most cases no anesthesia is needed
• Ideal cavity prep form
• Cleaner, faster, more controlled and less costly than air abrasion
• May perform multiple preps in the same amount of time it takes to do a single prep with anesthesia; results in more efficiency for your practice

Result: Conservative Prep
The Fissurotomy® Bur allows for exploration of fissures. It is virtually pain-free (to the DEJ) and creates an ideal cavity form. You can explore and restore in just 3-5 minutes.


Fissurotomy® Burs have a 100% rating from an independent non-profit dental products testing laboratory.

SS White has applied its 75 years of experience in rotary cutting instruments to bring new, uniquely designed metal finishing burs to the dental laboratory - specifically designed and conveniently packaged to be used with an improved metal finishing technique. SS White friction grip dental laboratory burs, used with the High-Speed Metal Finishing Technique described below, are designed to decrease metal finishing time substantially, while reducing the associated physical stress in the process.

EQUIPMENT REQUIREMENTS:

• High-speed friction grip handpiece
• Protective eyewear and apron

SAFETY FIRST:

1. Perform metal finishing in front of a local exhaust station.
2. Wear a full-face shield, or a face mask and safety eyeglasses.
3. Wear a nylon or plastic bib or apron.
4. Metal particles can irritate. Do not touch or rub eyes or face when metal finishing.
5. Wash hands immediately after metal finishing.
6. If skin is sensitive, wear fitted latex gloves during metal finishing.

INSTRUCTIONS FOR USE

NOTE: For best results use a pencil grip grasp and light pressure. Place the bur on the metal surface and move the rotating bur toward you.

Step 1 Gross Reduction
SS White cross-cut, large tapered cylinder, round-tip bur (EL1)
Begin gross reduction of the coping (metal substrate) at the sprue area with the EL1. Continue gross reduction of excessive bulk contouring the metal into the general shape and thickness desired.

Step 2 Gross Reduction
SS White cross-cut, large bud-shaped bur (EL2)
Further gross reduction may also be accomplished by using the EL2 to finish around metal collars, pontic connectors, and chamfer margins where a designated contour is required.

Step 3 Textured Finish
SS White cross-cut, thin cylinder, round-tip bur (EL3)
Now that the coping (metal substrate) has been contoured to the desired thickness, use the EL3 to place a textured finish on all porcelain bearing surfaces in preparation for porcelain application.

Step 4 Textured Finish
SS White cross-cut round bur (EL4)
Use the EL4 to finish all porcelain-bearing surfaces at chamfered margins, under pontics, and at embrasures to attain a textured finish in preparation for porcelain application.

Optional Technique:
If any pits or porosities become visible on the surface of the coping (metal substrate), use EL5 or FG7006 smooth cutting burs to refinish the metal surface until the imperfections are no longer visually apparent. Then, continue creating a textured finish with the EL3 or EL4 to prepare the surface for porcelain.
