title: Lingual orthodontics (part 1): laboratory procedure.
abstract: A key factor for successful correction of a malocclusion with lingual orthodontics is optimal bracket positioning. This presentation focuses on the development of an innovative laboratory procedure for indirect bracket positioning using a modified positioning device (TARG Professional) called Transfer Optimized Positioning System (TOP). In contrast to commonly used approaches to indirect bonding such as CLASS and BEST, the TOP System uses a target set-up technique in order to facilitate the 3-dimensional individualized positioning of brackets while allowing the brackets to be placed on the malocclusion model. The reliability and accuracy of this system in both the laboratory and the clinical environment are discussed. This discussion highlights the high precision of the TOP System and its significance in eliminating the usage of second and third order corrective archwire bends in the finishing stage of lingual orthodontic therapy. In other words the TOP System allows for the usage of almost flat orthodontic arch wires to successfully treat a malocclusion with lingual braces. This is the key factor in enhancing the cost effectiveness and success of a lingual treatment concept.
