Metal finishing in the dental laboratory setting is often a time consuming and physically stressful task. The Express Line High Speed Metal Finishing Burs are designed to substantially decrease metal finishing time and help reduce the physical stress in the process.
The SS White Express Line burs are used with a high-speed handpiece with light finger pressure thereby minimizing muscle fatigue and pain. The kit features six Express Line Metal Finishing Burs housed in a clear bur block.
- 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.
- 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.
- 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.
- 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.
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.
