From the translational medicine point of view, the use of biomechanical analysis to solve a clinical problem has rarely been reported. Here, we combined the clinical trial and 3-D finite element (FE) method to translate the clinical problem to the FE analysis and back to clinic. Twenty upper premolar extraction cases treated with customized lingual appliances were recruited in this study. Cephalometric films and cast records analysis showed that the “bowing effect”, which is a major side effect in lingual orthodontics, occurred during the first treatment stage with single lingual cable retraction. In order to translate the problem to biomechanical research, we introduced the 3-D finite element (FE) model of a customized lingual orthodontic system. The 3-D FE model including the maxilla, periodontal ligament (PDL), and dentition was constructed from human computed tomography data. The tendency of tooth movements in three dimensions and stress distribution in the PDL were analyzed by different mechanical loading methods. 3-D FE analysis confirmed the “bowing effects” and unexpected tooth movements with application of single lingual retraction force. Interestingly, we found that applying forces on both buccal and lingual sides, called “double cable” mechanics, could prevent the “bowing effect”. For the clinical trial, we applied the “double cable” force during space closure stage for 4 months, and confirmed “double cable” mechanics could correct and prevent the “bowing effect” clinically. Based on our results, both buccal and lingual forces should be used during space closure in lingual orthodontics to prevent and correct the “bowing effect”. Moreover, the magnitude of buccal force should not be lower than the force on the lingual side. Keywords: Lingual orthodontics, orthodontic tooth movement, three dimensional finite element analysis, translational study Introduction The demand for aesthetic orthodontic appliances has rapidly increased in recent years. Current options for aesthetic orthodontic appliances include labial ceramic brackets, clear aligners, and lingual brackets. Lingual orthodontics (LiO) are becoming more popular in modern society due to their lack of aesthetic impairment, and patients prefer lingual appliances for their invisibility. Although clear aligners are widely used by clinicians, they have difficulties in resolving severe cases. However, it is believed that various clinical and biomechanical differences exist between the LiO and conventional labial orthodontics (LaO) techniques, which can be attributed to many factors such as, differences in the position of brackets, reduced arch perimeter, and variations in the lingual anatomy. However, the detailed underlying biomechanical mechanisms are not well understood. A few specific techniques have been used in clinical situations to prevent these unexpected tooth movements. However, important questions like how to apply these forces and how the “double cable” mechanics work have not been investigated in either biomechanical or clinical research. Yet there are rare studies focusing on biomechanical research for lingual orthodontics. Though there are many application potentials for the FE methods in OTM, whether the findings can be translated into clinical situation still remains to be verified. Thus, the purpose of this study is to evaluate the biomechanical effects of “double cable” mechanics during the stage of space closure using 3D finite element analysis. And we try to translate the FE analysis findings back to clinical research through conducting a preliminary trial by analyzing the width of cast model and using cephalometric measurements. Materials and methods Patients recruitment and study design The study was designed as a pilot clinical trial using before and after self-control study. Patients were recruited between December 2011 to April 2012 at the department of orthodontics, Peking University Hospital of Stomatology ( Figure 1 ). Open in a separate window Figure 1 Flow chart showing enrollment, study inclusion, and data analysis. Four inclusion criteria were included: 1. Permanent dentition without congenital missing tooth 2. Extraction of upper first premolars for the treatment need 3. Using customized lingual orthodontic appliance. 4. Adult patients. Three exclusion criteria were included: 1. Moderate to severe periodontitis 2. Pregnant during the course of treatment 3. Patients with systemic diseases. Twenty participants, none of which was a smoker, with upper premolar extraction were included in this study. The study protocol was approved by the Institutional Review Board of Peking University, Hospital of Stomatology (PKUSSIRB-2011019). All of the patients were fully informed and signed consent. This study was registered in Chinese Clinical Trial Registry Center (ChiCTR-ONB-17013261).
