SmartIPR

smartIPR is a system that utilizes a vibrating (oscillating) handpiece with non-rotating disks to perform interproximal reduction (IPR). Unlike traditional hand strips, rotating disks, or high-speed air rotor burs, smartIPR creates space gradually while simultaneously polishing enamel. This approach offers greater control, improved precision, and enhanced safety for both the clinician and the patient.

Traditional hand stripping relies on manual movement, typically operating at approximately 1–2 cycles per second (Hz). In contrast, the smartIPR handpiece oscillates at 128–192 Hz, delivering significantly greater efficiency and consistency.

This higher frequency allows clinicians to create space more predictably with less physical effort, while maintaining excellent tactile control. Patients also notice the difference—smartIPR’s high-frequency motion delivers a smoother, more comfortable experience, unlike traditional hand stripping (often performed without lubrication), which can feel like a “nails on a chalkboard” sensation.

smartIPR delivers controlled vibrational energy through non-rotating disks. Because there is no spinning or cutting action, the system moves gently through tight contacts, helping reduce the risk of soft and hard tissue trauma while creating space between teeth.

Each smartDISK is divided into three working sectors:

U (up): Single-sided diamond coated, facing away from the handpiece (~0.07 mm)

D (down): Single-sided diamond coated, facing toward the handpiece (~0.07 mm)

UD (double-sided): Diamond coated on both sides and matches the labeled thickness

This design allows clinicians to begin with a thinner working surface and progressively move to thicker ones, enabling precise, step-by-step interproximal reduction.

smartDISKs are available in four sizes:

0.1 mm (labeled 1)

0.2 mm (labeled 2)

0.3 mm (labeled 3)

0.4 mm (labeled 4)

The number on each disk corresponds to the thickness of the double-sided (UD) sector.

The three-sector design provides procedural flexibility. Clinicians can use a thinner single-sided sector (U or D) to open tight contacts, then transition to the double-sided sector (UD) to achieve the final desired spacing—all with the same disk. The single-sided sectors also allow practitioners to selectively reduce enamel on one tooth surface while maintaining a non-coated surface against adjacent teeth for added safety.

Yes—if there is already sufficient space between the teeth to allow the disk to vibrate into and pass.

If no space exists, begin with the 0.1 mm disk using a single-sided sector (U or D, ~0.07 mm) to open the contact. Then:

Use the double-sided sector (UD) to reach 0.1 mm Move to the 0.2 mm disk, starting with a single-sided sector Finish with the double-sided sector to achieve 0.2 mm

Progression to larger smartDISKs requires adequate space, as smartDISKs rely on vibration rather than cutting.

No, a 0.5 mm disk is not currently available. To achieve 0.5 mm of space, use the 0.4 mm disk and polish the space to the desired width.

The 0.1 mm and 0.2 mm disks are used most frequently and will wear faster than larger sizes. While smartDISKs are durable, they will gradually lose thickness and effectiveness over time.

A 0.1 mm disk can be used to create interproximal space in up to approximately 100 contacts, depending on technique and clinical conditions. Because the system relies on vibration rather than cutting, sufficient space must be established before progressing to thicker disks to maintain optimal performance and efficiency.

IPR Glide acts as a lubricant during interproximal reduction (IPR), helping to reduce friction, heat, and patient discomfort. It also supports enamel protection and remineralization, making it beneficial during and after the procedure.

The smartIPR system requires a lubricant to properly facilitate the vibration of the smartDISKs as they move through the contact. Using the system without IPR Glide is not recommended, as it can reduce the lifespan of the disks and increase the risk of enamel damage.

IPR Glide can be applied either directly to the smartDISK through its lubrication perforations or to the occlusal surface between the teeth being treated.

A typical smartIPR system includes:

smartHANDPIECE – Oscillating/vibrating handpiece

smartDISKs in four sizes (0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm)

smartBLOCK – disk organizer

smartGAUGE – measuring gauge

IPR Glide is currently sold separately.

Kit contents may vary slightly depending on the distributor.

The smartIPR handpiece is designed to fit most slow-speed dental motors using a short E connection.

Offices using Midwest or Star air-driven slow-speed motors will require an air motor with a short E connection, as standard configurations may not be compatible. Most electric motors already have a short E connection and will operate the smartIPR handpiece.

When using an electric motor, operate within 20,000–30,000 RPM. For clinicians new to the system, a range of 20,000–25,000 RPM is recommended to optimize control and performance.
