However, further randomized testing in humans is still needed to confirm the claimed advantages of this technique and to evaluate the long term effects. Root resorption and tooth movement in orthodontically treated, calcium-deficient, and lactating rats. The sutures are removed after two weeks.

Corticotomy-Facilitated Orthodontics and Goal-Oriented Treatment Planning – Spear Education

Closure of an unusually large palatal fistula in a orthodontucs patient by bony transport and corticotomy-assisted expansion. These cuts are connected beyond the apices of the teeth when possible with a scalloped horizontal cuts.

Brackets and wires orhhodontics placed a few weeks to a few months prior to the surgery. Bone graft should be applied directly over the bone cuts and the flap sutured in place. Adults have more specific objectives and concerns related to facial and dental aesthetics, the type of orthodontic appliance and the duration of treatment.

Corticotomy surgery initiates and potentiates normal healing process Regional Acceleratory Phenomena Wilcko et al. Rapid orthodontic decrowding with alveolar augmentation: Open in a separate window. A full thickness flap is reflected and selective alveolar decortication is performed in the form of decortication cuts and points up to 0. Orthodontic treatment time with this technique will be reduced to one-third ofthodontics time of conventional orthodontics.

Accelerated osteogenic orthodontics technique: This article has been cited by other articles in PMC.

We now have an effective treatment option to offer borderline surgical orthodontic patients. Corticotomy, decortication, review, orthodontic treatment. Flaps should be carefully reflected beyond the apices of the teeth to avoid damaging the neurovascular complexes exiting the alveolus and to allow adequate decortication around the apices.


CAOT was compared to osteotomy-assisted tooth movement and to controls. J Oral Maxillofac Surg. The regional acceleratory phenomenon: Selective alveolar decortication is performed in the form of decortication cuts and at points up to 0. CAOT has also been used in the treatment of severe anterior open bite in conjunction with skeletal anchorage [ 3435 ].

Experimental animal research into segmental alveolar movement after corticotomy. Suya contrasted his technique with conventional orthodontics in being less painful, producing less root resorption, and exhibiting less relapse.

Corticotomy facilitated orthodontics: Review of a technique

PAOO effects and mechanism were confirmed by recent well designed histological studies. Published online Dec These techniques are aggressive in nature and less accepted by patients.

Flaps are then repositioned and sutured into place. National Center for Biotechnology InformationU. Corticotomy-facilitated orthodontic treatment was found to result in better retention compared to conventional orthodontic treatment [ 2428 ].

Hawang and Lee [ 37 ] demonstrated intrusion of supra-erupted molars using corticotomy, full-time use of magnetic appliances and night-time use of a vertical-pull chin-cup. Complications and Side Effects Although CAOT may be considered a less-invasive procedure than osteotomy-assisted orthodontics or surgically assisted rapid expansion, there have still been several reports regarding adverse effects to the periodontium after corticotomy, ranging from no problems [ 84144 ] to slight interdental bone loss and loss of attached gingiva [ 45 ], to periodontal defects observed in some cases with short interdental distance [ 46 ].

CAE is an effective technique for the treatment of maxillary transverse deficiency in adults and is assumed to provide greater stability and better periodontal health than conventional expansion, which can be less effective, dangerous and unstable in many patients. The aim of this article is to present a comprehensive review of the literature, including historical background, contemporary clinical techniques, indications, contraindications, complications and side effects.

Stability after orthodontic treatment may not always be achievable.

In an adult female patient, an impacted second premolar was facilitated to erupt spontaneously using corticotomy after creating enough lrthodontics as a part of an overall fixed orthodontic treatment, which included extraction of the first premolars and bilateral corticotomy-assisted expansion.


The regional accelerated phenomenon. Please review our privacy policy. In an animal study, Liou et al. J Jpn Oral Surg Soc.

Wilcko published a report about two adult patients with severe crowding who were orthodontice via AOO in just 6.

Cortical perforation can be made at selective areas to increase blood supply to the graft material Fig. Contraindications and Limitations Patients with active periodontal orthodotnics or gingival recession are not good candidates for CAOT.

All teeth as well as occlusal and soft tissue changes remained stable at the patient’s one-year retention visit.

Corticotomy facilitated orthodontics: Review of a technique

Acceleration of orthodontic tooth movement by alveolar corticotomy in the dog. The cortiicotomy active corricotomy time for the corticotomy-facilitated group was orthodojtics.

No effect on the vitality of the pulps of the teeth in the area of corticotomy was reported [ 47 ]. The observed effect of corticotomy was localized to the area immediately adjacent to the decortication cuts.

All proposed maxillary tooth movement was in the buccal direction. Several reports indicated that this technique is safe, effective, extremely predictable, associated with less root resorption and reduced treatment time, and can reduce the need for orthognathic surgery in certain situations Wilcko et al.

Bone graft consisting of demineralized freeze-dried bone and bovine bone with clindamycin was applied directly over the bone cuts and the flap was sutured in place. Following leveling and aligning, a full thickness flap was reflected and alveolar corticotomies were performed along the buccal surfaces of the maxilla, spanning from second molar to second molar.

Post-surgical instructions are the same as any standard oral surgical procedures.
