The lingual technique treatment offers the advantage of virtually invisible orthodontic therapy. It was originally introduced in the late 1970s. However, whereas initial results were promising they were followed by a phase of disenchantment as clinical and technical drawbacks were revealed: difficulties in bracket and arch application, disadvantages like increased time input due to more difficult bracket and archwire application and biomechanical problems such as reduced interbracket distance and the bowing effect were increasingly reported. The purposes of this retrospective study are to analyze a case series of patients treated with Lingual Orthodontic Treatment (LOT) and review the literature with regard to the efficiency, effectiveness, and stability of LOT. Three patients (2 females and 1 males, median age 22 ± 7 years, min 15, max 29 years) affected by malocclusion were enrolled in this retrospective study. There were 2 skeletal class 1 and 1 skeletal class 2 malocclusion. Orthodontic treatment was performed by using 3M Incognito Appliance Customized Lingual System (3MUnitek Orthodontic Products, Monrovia, CA). Lateral teleradiographic projections of the cranium were used. The cephalometric analysis was performed by using Dolphin Imaging System McLaughlin Cephalometric Analysis. Several variables related to teeth position were investigated. Pearson Chi Square was used to detect statistical differences among studied variables. In the present study we demonstrated that LSOT using 3M Unitek Incognito Appliance System is effectiveness tool to reach good clinical results since the vast majority of the studied variables (i.e. teeth position) have statistically significant differences between pre and post-treatment control.
