NTI with Invisalign

An NTI device (in this example a Lower device was used) can be thinned and sculpted to be adapted over an Invisalign tray with the ThermoPlasticBead material.  In order to prevent the "locking on" of the device and to facilitate placement and removal of the device, pre-lubricate the external of the Invisalign tray with Vasoline, and ensure that the TPB material does not wrap under the borders of the Invisalign tray.  The NTI device can then be readapted each time a new Invisalign tray is delivered.
