A novel method to accelerate orthodontic tooth movement

Abstract

This clinical case report presents fixed orthodontic treatment of a patient with moderately crowded teeth. It was performed with a new technique called ‘discision’. Discision method that was described for the first time by the present authors yielded predictable outcomes, and orthodontic treatment was completed in a short period of time. The total duration of orthodontic treatment was 4 months. Class I molar and canine relationships were established at the end of the treatment. Moreover, crowding in the mandible and maxilla was corrected, and optimal overjet and overbite were established. No scar tissue was observed in any gingival region on which discision was performed. The discision technique was developed as a minimally invasive alternative method to piezocision technique, and the authors suggest that this new method yields good outcomes in achieving rapid tooth movement.

Comparison of piezocision and discision methods in orthodontic treatment

“…The discision method was recently introduced as a case report [ 17 ]. The authors suggested that the discision method shortened the duration of treatment by performing rapid tooth movement.…”

“…The disc incision protocol was performed as defined [ 17 ]. Following local anaesthesia, vertical micro-incisions were performed to correspond to the centre of each interdental papilla and starting at 1 mm below the free gingival groove and crossing the mucogingival line.…”

“…The discision method may provide an alternative to the piezocision approach. The technique has been recently used successfully in an adolescent patient who had moderate crowding in both arches [ 17 ] and involves the use of a disc saw bur attached to a micromotor device, which is commonly used for arranging or cutting the ridge crest in dental implant surgery. Disc saws can be more ergonomic and economical than piezosurgery devices.…”

Corticotomy for orthodontic tooth movement

“…Recently, interest in corticotomies has increased again, and the development of the skeletal anchorage system has enabled the application of orthodontic forces as strong as desired, which not only moves the teeth physiologically, but also facilitates tooth movement mechanically. Corticision8910, piezocision11,12, micro-osteoperforation1314, and discision15 procedures have been used to perform corticotomies with minimal invasiveness.…”

“…Buyuk et al15 introduced a method using a disc saw that can be inserted into a handpiece because piezocision is difficult to perform in orthodontic clinics where there are no piezosurgery devices. To remove the cortical bone similar to conventional piezocision, a disc saw is used below the interdental papilla without incisions with blades.…”
