How Much is Enough?

In restorative dentistry there are certain requirements needed to fabricate restorations that will meet our needs as well as those of our patients.

One of our main issues is providing laboratory technicians enough clearance/reduction to fabricate a restoration properly. Common complaints include, “under-reduction” or “not enough clearance.” One of the ways we can avoid these issues is by using depth-cutting burs.

These burs are great tools for your restorative arsenal, but you don't have to go all out either. You most likely have depth-cutting burs right now in your office!

If you get an Iwanson caliper or a Boley gauge, you can measure the length and diameter of burs that you already own and use them appropriately. For example, a #330 carbide bur is 2mm in length and can be used as an occlusal reduction bur.

By knowing the size of the burs you use every day, you can achieve the reduction needed for your final restoration without having to purchase more items for your practice.
