corticotomy in orthodontics
Corticotomy has proven to reduce treatment time to as little as one-fourth the. National Center for Biotechnology Information.

Several authors have described cases in which moderate and severe crowding was treated without extraction by corticotomy or osteotomy-assisted orthodontics and in shorter periods of time.
. Bone graft should be applied directly over the bone cuts and the flap sutured in place. 1 A corticotomy is defined as a surgical procedure whereby only the cortical bone is cut perforated or mechanically altered. The aim of this prospective study was to evaluate the effectiveness of an innovative minimally invasive flapless corticotomy procedure in orthodontics.
This technique does not seem to. They stated that the tooth movement was 16 times faster when rotary instruments were used compared to that of piezosurgery. It has gradually gained popularity as an adjunct treatment option for.
It generates the localized RAP at the site of injury Wilcko et al. 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. 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.
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. Tooth movement should be initiated two weeks after the surgery. Introduced surgical orthodontic therapy which included the innovative strategy of combining corticotomy surgery with alveolar grafting in a technique referred to as Accelerated Osteogenic Orthodontics AOO and more recently to as Periodontally Accelerated Osteogenic Orthodontics PAOO6789 Fig2.
Combining corticotomy with bone grafts was assessed. 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. It is an established and efficient orthodontic technique that has recently been studied in a number of publications.
The accelerated tooth movement technique was described for the first time by Köle 5. Corticotomy and osteotomy are used in orthodontics primarily to resolve crowding in a shorter period of time. However within the limitations of this review the corticotomy procedures were able to statistically and clinically produce significant temporary decrease in orthodontic tooth movement rate.
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. Corticotomy-assisted orthodontic treatment was initially presented in case reports2-6 Many human and animal studies were later conducted to test the effectiveness of this technique7-172425 Most published papers indicated that performing cortical and alveolar bone cuts around the roots of teeth would help accelerate tooth movement1 However the. In a study by Farid et al in dogs corticotomy-facilitated orthodontics using piezosurgery versus rotary instruments was compared.
Significant acceleration in orthodontic tooth. Wilcko et al. They attributed it to the amount of trauma created by these rotary instruments and also noticed.
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. The medullary bone is not changed. High heterogeneity among studies made it difficult to draw clear conclusions.
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. National Center for Biotechnology Information. 2001 due to which bone regenerates faster than the normal regional regeneration process.
This is in contrast to an osteotomy which is defined as a surgical cut through both the cortical and medullary bone. 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. The STROBE guidelines were followed.
