Robotic Wire Bending in Orthodontics

D. Vaishnavi*, Jayachandran Sheethal, Kumar Kishore

Malocclusion is the third largest oral disease in the world. At present, the most effective treatment method for malocclusion is the fixed orthodontic technique. Archwire bending is one of the key components in orthodontic treatment. However, it is a very difficult work due to the high stiffness and super elasticity of orthodontic wire. The traditional way of acquiring the formed archwire curve is based on manual operation, which will randomly bring numerous errors caused by human factors. In clinics, customized archwires are demanded for lingual orthodontic treatment. Traditionally, these archwires could only be bent by experienced orthodontists manually. This pattern requires a specialized skill training, precision and occupies long chairside time, but still cannot ensure the accuracy of appliances. So what are the recent advances to overcome the shortcomings of archwire bending? Robotic archwire bending can overcome the shortcomings of manual bending by increasing the treatment accuracy, efficacy and efficiency, also decreasing the treatment time and patient discomfort thus improving the orthodontic treatment in general.
