A Simple Technique Using a Modified Nance Appliance as Anchorage for Maxillary Molar Distalization—Two Case Reports

Maxillary molar distalization to correct a dental Class II relationship and create space relieve crowding has been long-lasting subject of debate in orthodontics. Generally, distalize maxillary molars, an intra-arch appliance is favored over inter-arch since it does not utilize mandibular dentition as anchorage, so some unwanted side effects on incisors can be avoided. A variety appliances have developed such the pendulum, Jones jig, first class appliance, distal jet, modified C-palatal plate. Although they could achieve efficient distalization, learning curve proper insertion activation relatively long. In addition, are comfortable for patients due bulky units, especially when units designed palatal area. The current manuscript describes novel effective appliance—a Nance technique, which consists of: (1) palatally, big acrylic button against rugae connected premolars with wide mesh pads; (2) buccally, regular brackets molars sectional round stainless steel archwires open coil springs between second premolar molar. Either bilateral or unilateral achieved this elastics needed. It simple fabricated, delivered, activated, patients.
