How IPR is calculated, adjusted, and reported

IPR.mp4

Currently, IPR represents interproximal collision, not interproximal reduction. It gets automatically added whenever two teeth move into contact with each other. An equal amount of material gets removed from both teeth. A red line represents the area of collision, and a number in millimeters above the area of contact displays the amount of interproximal collision.

How to remove interproximal collision

There are 3 ways to remove interproximal collision:

• Click Remove IPR/Gap in the Tools panel. This will remove all interproximal collisions and gaps.
• Click the ‘x’ icon on gum to remove the selected interproximal collision/gap.
• You can add or remove interproximal collision between any two teeth in 0.1mm increments by clicking the Up or Down indicators above the interproximal collision/gap. It does this by reducing the arch circumference without changing inner-canine width.

There is one way to hide interproximal collisions: Use IPR on the Layers panel on the bottom left to control its visibility.

Where to know the total amount of interproximal collision

When you export your models, an export report gets generated along with your models and saved with them. This report gives the total amount of interproximal collision to perform at each location.‍ It depends on you at which stage the IPR should be processed.
