Busch Diamond Bur | Busch No. 8392 016 – Fine Grit, Red Ring – FG | IPR Interproximal Needle Bur | Pack of 2
The diamond dental bur fine grit FG 016 (Busch No. 8392) is a slender, fine-grit diamond needle bur from Busch & Co. GmbH, suited to controlled finishing of proximal surfaces. Clinicians commonly use needle burs of this figure for interproximal reduction (IPR). The fine grit, identified by the standard red ring color code, makes it immediately recognizable in any clinical setting. Supplied in a pack of two.

Interproximal Reduction (IPR) With the 8392 Bur
Interproximal reduction, also called enamel stripping or slenderizing, removes a thin, planned layer of enamel from the contact surfaces between neighboring teeth. Clinicians use it to create the small amount of space that aligner or orthodontic treatment calls for, or to reshape a contact. The slim head of the 8392 can be introduced into a tight contact where a wider bur cannot, and the fine grit takes enamel away gently and leaves a smoother surface than a coarser diamond, so less polishing follows.
This product page does not set IPR parameters. The amount of reduction, and which surfaces receive it, comes from the treatment plan set by the orthodontist or the aligner company, and technique is the clinician's decision. For holding strips under tension in the interproximal space, see the Strip Grip® strip holding tweezers and our guide to interproximal finishing. Read the IPR guide for burs, strips and chairside instruments in aligner cases. Practices running aligner cases may also want the Helmut Zepf aligner pliers.
Clinical Applications
