All About IPR: Planning, Execution, and Results.

IPR is a quick and straightforward orthodontic procedure in which the sides of the teeth are minimally filed to create room for teeth movements to happen. It is essentially a slight reduction in the tooth enamel (outermost tooth layer). 

Although this method is not used in all orthodontic treatments, it is vital in many cases, and dentists tend to have a very tactical and well-planned approach to it. 

Today we will talk about the overall process, tools, and execution and how Eon Aligner helps dentists deliver the best treatment experience to patients. 

How is an IPR decided?

IPR offers a proven, relatively non-invasive method for creating space that will help the aligners work more effectively. Tthe leading indicators of needing IPR are mainly the following:

  • Crowding.
  • Class II minor malocclusions.
  • Class III minor malocclusions.
  • Tooth size discrepancy.
  • Recontouring of teeth.
  • pre-treatment 'black triangles.'
  • Correction of the Curve of Spee (the anteroposterior curve determined) by the occlusal alignment of the teeth.

How is IPR performed?

Teeth are made up of tooth enamel, dentin, and pulp tissue (containing nerves and blood vessels). During IPR, the orthodontist removes a marginal part of the outer surface or the enamel, usually on the sides of the teeth to create space between movements. The safe amount of IPR that can be performed can reach half of the proximal enamel, and any more will need specific case-by-case work.

 

The Preparations Stage

As a dentist, you will have to conduct a thorough check to ensure the IPR is well planned, from taking the teeth measurements to selecting the suitable tools and treatment outcomes.

This evaluation is done at the first appointment with the patient. The patient’s 3D scan will help you better understand the case and its implications. You will be able to proceed with the IPR plan once you discuss it with the patient and confirm it with Eon Aligner’s clinical team.

 

How is the Enamel Removed?

After the orthodontist identifies where the IPR is to be performed, the enamel filing process is performed either manually or mechanically. 

Manual options include:

  • Handheld strips
  • Files used with the manual holder

Mechanical options include:

  • Files used in the oscillating handpiece.
  • Discs mounted on a straight slow-speed handpiece (anterior use only)
  • Burs mounted in a high-speed handpiece (Air Rotor Stripping or ARS)

It's essential to always keep in mind the 4 principles for IPR: accuracy, timing, measurements, and safety.

This process only takes a few minutes and is conducted based on a professional plan. It does not cause any pain as the enamel has no nerves. The quick procedure does not change the structure of the teeth and doesn't even require anesthesia. In some cases, fluoride varnish is applied after performing IPR to avoid sensitivity.

The dentist will solely remove a minuscule layer, keeping the tooth intact and after that, the dentist will have sufficient space to proceed with the next treatment step.

The Final Say 

While the IPR procedure is essential in many teeth straightening treatments using aligners, a patient may not need it, depending on their case. Ultimately,  it is a better alternative to tooth extraction in cases where extra space is required in the dental arch to move teeth.  eg. mild to moderate crowding
