RESUMO
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.

The Incognito lingual appliance has a ribbon-wise slot with vertically inserted wires. Control of tip can be problematic with this appliance and the conventional method to overcome this is to achieve full wire engagement via the use of power-ties. Although effective, these can be very difficult to place and also create very high friction. A method of ligation is described which consists of a modified elastic double over-tie. This is easily placed and very effective at controlling tip in Incognito brackets using a variety of arch wires. This method creates less friction than the power-tie.
