Comparison of tooth movement between techniques that use braces fixed in front surface of teeth and braces fixed on the back surface of teeth

Conditions: malocclusion diagnosis of Angles Class I (bidentoalveolar protrusion) or Class II division 1 with the treatment plan of extraction of maxillary 1st premolars required with maximum anchorage

Brief Summary: Lingual Orthodontic technique, a novel innovation towards an aesthetic-focused approach, attracts the attention to be an unparalleled ideology as a complete truly invisible technique. In Premolar extraction cases, En-masse anterior teeth retraction is preferred over two-step retraction because of aesthetic and mechanical considerations. The Challenge posed during retraction may be attributed to the moment generated in the maxillary anteriors, making the torque control during retraction a tougher challenge in Lingual orthodontics than labial. The Efficient and most predictable way to effectively retract maxillary anteriors is by biomechanically optimizing the retraction force vector. Micro-implants, apart from anchorage reinforcement can help to optimize the force vector. The Micro-implantâ€“Lever arm designs a mechanical plan based on Class-1 lever mechanics of Physics; can circumvent the limitations of adverse moment to force ratio and offer a goal oriented treatment planning. Though many clinical studies have been done to assess Micro-implant-Lever arm mechanics in labial orthodontics, information and researches on lingual orthodontics are still deficient and are fastened at the level of finite element analysis and few case reports. Thus clinical trials on this topic are needed to explore & record the method.
