IPR Bur Kit: 7 Interproximal Reduction Burs in One Autoclavable Block

The Eagle IPR bur kit puts everything you need for interproximal reduction in one place: 6 diamond IPR burs plus 1 diamond stripping bur, covering 0.3–0.65 mm, in a bur block that autoclaves to 135°C. The same IPR burs you can buy individually - packed as a set, at a lower price.

Eagle IPR burs are designed to work parallel to the long axis of the tooth rather than perpendicular. That gives you a stable finger rest, a clear view of the contact, and uniform enamel reduction along the full proximal surface - the reasons clinicians move from strips and discs to burs.

What's in the IPR Kit

All burs: FG shank, electroplated diamond coating, manufactured in Israel. The J316 anterior bur was described in the Journal of Orthodontics (Har-Zion, 2025) as a design that performs anterior IPR effectively and safely while avoiding the discomfort of traditional methods.

Available Options

• IPR Kit - 7 burs + block. The standard interproximal reduction kit.
• Advanced IPR Kit (Ortho Kit) - the same 7 burs plus 5 carbide debonding burs and 2 polishers for attachment and adhesive removal. See the full Orthodontic IPR Kit page.
• 3 IPR Kits (discount pack) - for multi-chair clinics; one block per operatory.
• 5 IPR Kits (special offer) - clinic or group-practice pricing.
• IPR Refill Pack - 35 burs (5 full sets) without blocks. For clinics that already own the block and reorder burs only.

IPR Kit for Invisalign and Clear Aligners

ClinCheck and other aligner planning software prescribe IPR in 0.1 mm increments, and the kit is built around that range: J316 for 0.3–0.4 mm anterior spacing, Z12S for 0.45–0.5 mm staged reduction, E11S for 0.55–0.65 mm where posterior contacts limit visibility. Verify each reduction with an IPR gauge before moving to the next contact.

The same set works for fixed appliances - it is an ortho IPR kit first, an Invisalign IPR kit second.

Clinical Applications

• Clear aligner therapy - controlled interproximal reduction for Invisalign® and other aligner systems
• Orthodontic treatment - space creation and Bolton discrepancy correction
• Restorative dentistry - contact point and emergence profile refinement
• Aesthetic dentistry - black triangle reduction and proximal recontouring

How to Use the IPR Burs

1. Open the contact first. Place a wedge to tip the teeth slightly apart and protect the gingiva. Start from the lingual side, where the contact usually sits.
2. Set the angle at low RPM, then increase to maximum speed. Keep the bur parallel to the long axis of the tooth.
3. Light, continuous strokes with ample water. If you feel resistance, switch to short push-stop motions. Never force the bur.
4. One contact at a time. Measure with the gauge, record the reduction, then move on.
5. Finish and polish. Smooth the proximal surface with a fine strip or the J313 finishing bur. A polished surface holds less plaque and gives the patient less sensitivity.

Tips From Clinicians

Collected from published clinical guides and orthodontists who perform IPR daily:

• Check that the contact is fully open before you measure. You will feel the resistance drop and see slight blanching of the papilla. Then confirm with the gauge - not before.
• Keep proximal surfaces parallel. Flared burs tend to remove more incisally than gingivally, leaving a contact that is wider at the top. Cylindrical profiles like the E11S give the same reduction whether held vertically or horizontally.
• Ledging comes from rushing. Rigid air-rotor burs and discs are the usual cause. Open the contact with a wedge or a strip first, then let the bur cut - don't push it.
• Make the tooth a smaller version of itself. After reduction, contour the line angles so the tooth keeps its natural shape (Sheridan's principle). The two-part J316 does this in the same pass.
• Posterior IPR is different. Less visibility, wider crowns, and the contact sits further back. Use the longer E11S and work from the lingual, one contact at a time.
• Always polish. Burs leave a rougher surface than strips. Studies comparing IPR methods with and without polishing consistently show a smoother, less plaque-retentive enamel surface after finishing. Keep a fine strip or the J313 finishing bur on the tray.
• Run a floss or explorer check after each contact to catch any ledge or sharp edge before you seat the next aligner.
