17. Old IPR Staging Original position If IPR is done at this time, it will remove part of the lingual face in UL1(black mark) Final position – Lingual area that would be have to be removed by IPR needlessly since it keeps shifting as the teeth are rotating.

35. By Doctor Request ONLY! Doctor may request 1 mm thick Vertical Rectangular attachment for mesio-distal root tip. Root Tip Doctors may request attachments when retention/anchorage is a concern during certain movements or conditions i.e. expansion or short clinical crowns More than two vertical rectangular attachments per quadrant may provide too much aligner retention. Aligner Retentiveness Doctors may request attachments be added starting at stage 2 so the patient can first get comfortable in placing and removing aligners with first set without the added retention the attachments provide. Patient Comfort Align does not place attachments on all extrusions by default. Doctor may request attachments for extrusions not included in default. Extrusions of other teeth Doctor may request attachments for rotations not included in default. Incisors generally do not need attachments for rotation. Rotation of other teeth Description Situation Doctor may request Horizontal Beveled attachments placed on the incisal third of upper anterior teeth for bucco-lingual root torque to prevent aligner dislodgment. Root Torque Always review ClinCheck using the Superimposition Tool to determine if attachments are placed on teeth that might need them
