Evaluation of the Levels of Pain and Discomfort Between Piezosurgery-assisted Corticotomy Versus Traditional Method of Aligning Crowded Lower Anterior Teeth: a Randomized Controlled Trial

According to the American Association of Orthodontists (AAO), the length of comprehensive orthodontic treatment ranges between 18-30 months, depending on treatment options and individual characteristics. In addition, orthodontic treatment time ranges between 25-35 months for extraction therapies, respectively. Reducing orthodontic treatment time is one of the main goals for orthodontists, due to problems such as root resorption, periodontal disease and caries that are associated with prolonged treatment time.

Many techniques have been introduced to accelerate orthodontic tooth movement; surgical and non-surgical. The surgical approach is the most clinically applied and most tested with known predictions and stable results. Surgical approaches usually vary from total block osteotomies to flapless partial corticotomies .In spite of corticotomy-assisted orthodontic treatment efficiency, the invasiveness of these procedures (i.e. requiring full mucoperiosteal flaps elevation) might have limited their widespread acceptance among orthodontists and patients. Therefore, more conservative flapless corticotomy techniques have recently been proposed. These procedures can be accomplished in a reasonably short periods that might produce less pain and discomfort, so we will gain better patient acceptance. Although various techniques of flapless corticotomy have been reported to be successful in practice, scientific evidence on their acceptance and compatibility is little in the literature.
