corticotomy in orthodontics
The corticotomy surgery accelerates tooth movement in areas aimed by the surgery because of the demineralization. The STROBE guidelines were followed.

Treatment planning with corticotomy-facilitated orthodontics Orthodontics combined with selective alveolar decortication and bone grafting may be an alternative treatment plan for borderline orthognathicorthodontic surgical cases.
. Fischer in 2007 treated 6 patiens with bilaterally impacted canines. Corticotomy facilitated orthodontics has been employed in various forms over the past to speed up orthodontic treatments. Lately one of the most used has been corticotomy.
Corticotomy-assisted orthodontic treatment was used in the treatment of bimaxillary protrusion as an adjunct to manipulate skeletal anchorage without any adverse side effects in only one-third of the regular treatment time. Corticotomy was found to produce bone to augment the confining bone during tooth movement. 1 A corticotomy is defined as a surgical procedure whereby only the cortical bone is cut perforated or mechanically altered.
Corticotomy Orthodontics Tooth movement Corticotomy-assisted orthodontics. The mean age of these patients was 21 years range 17-28 standard deviation 608 years. It generates the localized RAP at the site of injury Wilcko et al.
In these cases the total treatment time was reduced to one-third to one-fourth that of traditional nonextraction and extraction orthodontic treatments3The current corticotomy procedures adopted or modified by most clinicians are based on Heinrick Köles combined radicular corticotomysupraapical osteotomy technique first described in 1959Köles. Alveolar corticotomy is a surgical intervention limited to cortical bone that is incorporated into orthodontic treatment plan to facilitate the treatment of complex occlusal problems Köle 1959. Adding a bone graft to the area of decortication allowed a profound modification of the alveolar basis and exceptionally boosted the treatment options Wilcko et al 2001.
The accelerated tooth movement technique was described for the first time by Köle 5. Ten patients with severe dental crowding and a class I molar relationship were selected to receive orthodontic treatment with clear aligners and corticotomy-facilitated orthodontics. This is defined as a surgical procedure in which the cortical bone is cut perforated or mechanically altered without actually affecting the medullary bone 5.
Thanks to the work of the Wilcko brothers and their PAOO technique corticotomy became a tool not only to speed up orthodontics but also to enhance it. It is an established and efficient orthodontic technique that has recently been studied in a number of publications. Different techniques both surgical and non-surgical are used as coadjuvants of orthodontic treatment 4.
The full alignment of severely crowded lower anterior teeth took about 59 less treatment time with this technique compared to the conventional. National Center for Biotechnology Information. It was first introduced in 1959 by Kole as a mean for rapid tooth movement.
The piezocision flapless corticotomy method was very effective in accelerating orthodontic tooth movement in severe dental crowding cases when the treatment was accompanied with premolar extractions. Facilitated tooth movements will occur only close to the corticotomized teeth. The corticotomy technique has several advantages including faster tooth movement shorter treatment time safer expansion of constricted arches enhanced post-orthodontic treatment stability and an extended envelope of tooth movement 2 3 4.
After a healing period of one or two weeks orthodontic tooth resorption around the moving teeth by day 21 after surgery movement is started and then followed up using a faster rate and the area refilled with bone after 60 days. Corticotomy forms a part of the periodontally accelerated osteogenic orthodontics PAOO technique which also includes orthodontics and the placement of a bone graft. 2001 due to which bone regenerates faster than the normal regional.
Randomly one canine was surgically exposed with a conventional. Seven studies were selected published between 2007 and 2016 to highlight the main results achieved with this method. The use of surgical techniques to accelerate orthodontic tooth movement has been developed.
The medullary bone is not changed. It was believed that the main resistance to tooth movement was the cortical plates of bone and by disrupting its continuity orthodontics could be completed in. Corticotomy facilitated orthodontics advocated for comprehensive fixed orthodontic appliances in conjunction with full thickness flaps and labial and lingual corticotomies around teeth to be moved.
This is in contrast to an osteotomy which is defined as a surgical cut through both the cortical and medullary bone. It was also used to achieve molar distalisation. It can be done either on the.
Corticotomy involves the creation of shallow perforations or cuts made in the cortical alveolar bone while the trabecular or medullary bone is left intact in order to induce an acceleration of the normal physiological processes involved in bone healing 11. Most of the included SRs addressing this topic agreed that corticotomy prior to the commencement of an orthodontic tooth movement was a safe and effective treatment to accelerate the rate of dental. By means of surgical burs vertical grooves in the cortical plate corticotomy are produced mesial and distal to the roots of teeth that are being moved 3 mm below the marginal crest and extending beyond the apex.
According to the Wilcko brothers treatment time could be reduced from ⅓ or ¼ of the treatment time that is typically required. The male to female ratio was 21.
