Although excessive and prolonged orthodontic treatment might result in loss of pulp vitality Hamersky et al. Comparison of corticotomy-facilitated vs standard tooth-movement techniques in dogs with miniscrews as anchor units.
A complete flap was performed on the vestibular and palatine surfaces to expose the alveolar bone in the region of the maxillary first molar. On the maxillary second molars and pre-molars, a double tube was welded to allow insertion of the stainless steel archwire.
In addition, pulp stones were formed only in the severe-force group, and odontoblast disruption, vacuolization, moderate vascular congestion, and no necrosis were observed in both force. MIRO reduce el tiempo de tratamiento de ortodoncia, evitando los efectos adversos reportados por la ortodoncia acelerada. Influence of orthodontic forces on human dental pulp: This technique has proven to be effective, but also invasive: After corticotomies, the patients were prescribed a soft diet and prohibited from using mouth rinse for 24 h.
Neither technique is sufficiently accurate because both lack radiographic reference points as guide for the surgical procedure. The incisions began 2 mm below the papilla.
Rapid orthodontic tooth movement aided by alveolar surgery in beagles. However, it has an important drawback, the repeated malleting could cause dizziness in real patients Penarrocha-Diago et al. A Pretreatment frontal view showing the surgical guides placed where the incisions will be performed. The rapid tooth movement obtained after the selective alveolar corticotomy local physiological changes such as reduced bone density and therefore less resistance to tooth movement Hassan et al.
Regarding molar intrusion, the protocol adopted promoted intrusions that ranged from 1.
Evaluation of the quantity of first molar intrusion. After careful irrigation, the flap was repositioned and appropriately sutured.
Selective alveolar corticotomy to intrude overerupted molars. No ortodooncia was indicated. Moreover, a minimally invasive flapless procedure is described. The intrusion of all teeth was obtained mean 2. Evaluation was made by means of superimposition of complete cephalometric tracings em the facial structures and the maxilla, originated from lateral radiographs of the face teleradiographs obtained before treatment and after molar intrusion. Accelerating orthodontics by altering alveolar bone density.
Surgically facilitated orthodontic treatment: Slight swelling of the soft tissue was observed during the first days post-operative.
Ortodoncia Facilitada por Corticotomía
This study aimed to evaluate the impact of selective alveolar corticotomy associated with orthodontic intrusion on pulp vitality of overerupted maxillary first molars. The aim of this report is to present the clinical results of a minimally invasive rapid orthodontic procedure MIROwhich maintains the advantages of speedy orthodontics described by Chung et al. Radiographic metal guides were positioned between each tooth and digital radiographies were taken to assure that the metal pin did not project over the tooth roots.
Rapid orthodontics with alveolar reshaping: C Right side view; D Left side view. A year-old woman came to the clinic asking for a fast orthodontic treatment. Rapid canine retraction through distraction of the periodontal ligament. This surgically facilitated orthodontic treatment did not promote pulp damage.
In order to assess whether the intrusion of upper molars associated with selective alveolar corticotomy would have a deleterious effect on the neurovascular bundle of these teeth, thermal Endo-Ice and Heated gutta-percha and electric tests were performed before and at the end of intrusion. It is a surgical procedure in which only the cortical bone is cut, drilled or mechanically altered Bhattacharya et al.
In these situations, the intrusion of molars configures as the best treatment option. At two months, the appearance of the arch had changed considerably in the maxilla and mandible, and the crowding was corrected almost completely, such that the patient was ready for orthognathic surgery Fig.

In a previous study that evaluated the pulp vitality of teeth undergoing moderate 50 g and severe g intrusive orthodontic forces, electrical and thermal heated gutta-percha tests were performed to assess pulp involvement of teeth intruded, them histological analysis was carried out on extracted teeth.
Selective alveolar corticotomy is an alternative to accelerate the orthodontic treatment in adults. Selective alveolar corticotomy associated with orthodontic treatment may also be indicated for the extrusion of ankylosed teeth, nonextraction treatment of crowding, canine distalization and intrusion of overerupted maxillary molars Oliveira cortkcotomias al.
The onset of RAP in alveolar bone is accompanied by a burst of osteoclastic activity resulting in lower bone density and augmented osteoblastic activity Ferguson et al.
Acceleration of orthodontic tooth movement by alveolar corticotomy in the dog. Moreover, osteoclastic activity is known to be integral to tooth movement. Surgical operations on the alveolar ridge to correct occlusal abnormalities. The proposed technique avoids the elevation of the flap, retaining the characteristics of conventional orthodontics, which normally do not require bone grafts.
Tratamiento Orto-perio: Corticotomia+Ortodoncia Clase III, mordid
Revascularization and bone healing after maxillary corticotomies. Buccal bone remodeling after immediate implantation with a flap or flapless approach: This innovative technique was tested in this animal model.
Noteworthy morbidity associated with osteotomy includes the risk of lost tooth vitality, avascular necrosis of the osseous block. The following were excluded from the sample: New therapeutic modalities to modulate orthodontic tooth movement. However, these techniques have not been widely embraced by the dental community since they require extensive full thickness flap elevation and in ortodoncla of osteotomy, an invasive procedure associated with postoperative discomfort and a high risk of complications leading to a low acceptance by the patient Kim et al.
An evidence based analysis of periodontally accelerated orthodontic and osteogenic techniques: MIRO also enhances accuracy by relying on radiographic surgical guides that help to make a precise corticotomy avoiding damage to vital structures and teeth.
Corticotomy was first mentioned at the end of the 19th century Bhattacharya et al.
