Discover how to correctly use our Interproximal Reduction (IPR) strips when treating your patients. Here are our top tips:
Not all Smilelign cases require Interproximal Reduction (IPR), though it is common in crowding cases. Your treatment plan will detail the measurement of IPR required in each zone. It is essential that you follow this to ensure a smooth treatment.
The simplest method for creating space accurately is with IPR strips. Available in a range of thicknesses, these can be purchased via our website as part of our IPR Kit. The kit also includes extras such as burs, wheels, and an IPR gauge for measuring space created.
It is essential when undertaking IPR to respect the natural anatomy of the teeth. It is important to keep the IPR fully parallel and down to the gingiva. The IPR should be contoured to the tooth’s morphology.
For cases which require more than 0.3mm in a specific IPR zone, progressive IPR is recommended. A minimum of 0.3mm will need to be created before the patient wears their first aligner. The remainder of the IPR can then be completed once the initial space has closed. This space is usually closed within the first couple of aligners. Regularly check with an IPR gauge when conducting IPR to ensure accuracy and adhere to the recommended amount.
For cases presenting crowding, we recommend monitoring the contacts of the teeth being moved throughout treatment. At each aligner change, monitor the contacts. If these appear to be binding or restricting the movement, we recommend running a thin IPR strip through the teeth.
The attachment template will come as two parts: a soft inner lining and hard outer shell.
Ensuring the template is clean, check the fit on the teeth.
Prepare the teeth that will have the attachments placed in line with your chosen composite manufacturer’s instructions.
Ensure the soft lining is placed correctly inside the hard shell. Making sure the template is dry, place a small amount of composite in the void where the attachment will be. You can use flowable or paste composite. If using paste, a spatula may be required to firmly pack the void.
Seat the template firmly onto the teeth, ensuring it is fully seated around the arch.
Cure the composite according to the manufacturer’s instructions.
Remove the outer shell first, followed by the soft inner lining, and test that the attachment is firmly bonded. Remove any excess or flash with usual composite polishing burs, ensuring you do not alter the shape of the attachment in the process.
