Avoiding pitfalls in planning with the Incognito lingual system

Incognito is a fully customized lingual fixed appliance system of high precision and limited adjustability. It is therefore important to incorporate as much detail as possible into the planning and communication of the appliance prescription. A systematic approach to this is suggested, breaking it down into torque, tip, tooth width and morphology, vertical tooth positioning, arch width and arch form. The clinician relies upon the laboratory technician to interpret correctly this guidance in the preparation of the set-up. Verification of the set-up by the clinician before appliance manufacture is not compulsory. The potential risks of not verifying the set-up are discussed.
