Directa's ContacEZ IPR Rainbow Set streamlines workflows and offers a better patient experience

When performing interproximal reduction (IPR), Dr. Christina Carter doesn’t have to worry about taking off too much enamel, a common risk. With the ContacEZ IPR Rainbow Set from Directa, she knows just how much she’s removing—without using a gauge or a ruler.

 

“I’m very calibrated as to how much tooth structure I’m removing,” said Dr. Carter, who is dual trained in pediatric dentistry and orthodontics, offering both services to her patients at Carter Smile in Madison, NJ. "Sometimes, based on my aligner treatment plan, I just want to remove a little bit. Being able to use different sizes allows me to work more quickly and efficiently, and to have a better workflow.”

 

The strips come in various sizes, and the few minutes they save per procedure adds up over the course of the day, Dr. Carter noted. Not having to measure removes a step from the process, and it's one less item her assistant has to put on the tray.

 

A Better Experience for Everyone

 

The IPR Rainbow Set includes 24 autoclavable strips in a range of grits, thicknesses, and coatings, with an ergonomic single-handed design for tactile control and a central opening for maximum visibility.

 

“Because the IPR Strips are small and have a plastic frame around them, I can hold onto them easily and don’t have to worry about lacerations to the patient’s lips or tongue, or damaging the surrounding tissue,” Dr. Carter said.

 

How They Compare

 

The IPR strips take less time and are more accurate, Dr. Carter shared, and patients find the colorful strips less intimidating than others. She also prefers the Rainbow set to other options, including wheels.

 

“I feel like I don’t have as much control over the wheels,” she said. “And I’ve used other strips that tear, which is frustrating. Because they’re long, you have to loop them around your fi nger. There’s always the risk of catching the patient’s cheek, tongue, or gum. It can be cumbersome.”

 

Dr. Carter added that the flexible diamond strips slide beautifully between the teeth without having to worry about sharp edges. “I have a little bit of flex in the strip, so I can reshape and round out the corners or edges of the teeth more efficiently. They just give you beautiful contour.”

 

Affordable and Reliable

 

The Rainbow set contains everything needed for accurate IPR. It’s easy for Dr. Carter to communicate which strip she wants to her assistant by calling out the number, color, or single- or double-sided.

 

 

The ContacEZ IPR Strips also hold up longer than other options, which helps inventory and cost savings. “They’re very cost-effective,” she said. “And you get reproducible results every time you use them.”
