Performing IPR

  • Have your assistant direct an air stream across the IPR site away from your and the patient's face
  • Be sure to constantly observe both the labial and lingual aspects to ensure that the teeth are not being cut inappropriately
  • Use light pressure on the instrument - let the abrasives do the cutting
  • Perform the amount of IPR indicated on the treatment plan:
  1. 0.1 mm IPR can be achieved with abrasive strips that are 0.08mm (extra fine),0.10mm (fine),and 0.13mm (medium) 
  2. 0.2 mm IPR can be achieved with a one-sided disc that is 0.1 mm thick 
  3. 0.3 mm IPR can be achieved with a two-sided disc that is 0.15 to 0.2mm thick, by gently moving the disc back and forth, mesially and distally in the interproximal space until the desired space is made
  • To confirm that the contact has been fully broken, stop the instrument and gently push it against the gum tissue
  • When reducing a contact, be sure to break the contact all the way through. The resistance will diminish and the gum tissue will blanch
  • Confirm interproximal space created by using an IPR thickness gauge
  • Idealize the tooth anatomy post-IPR:
  1. Angulate the cuts so that they do not disturb the appearance of the tooth
  2. Check the reduced surfaces with an explorer or floss to see if there are any nicks or "ledges" on the tooth
  3. Use diamond burs or abrasive strips to round off any sharp corners

 

  • Document IPR performed including the amount and location. You can use the IPR Tracking Chart in the Help Center or place notes directly on the treatment plan or other paperwork
