The surgical protocol used was based on a previously described procedure In these situations, the intrusion of molars configures as the best treatment option. This suggests that selective alveolar corticotomy did not ortodocia pulp damage, and can be considered an effective and safe auxiliary method to intrusion of overerupted maxillary molars.

Comparative evaluation of dento-alveolar distraction and periodontal distraction assisted rapid retraction of the maxillary canine: The patient accepted the treatment and signed an informed consent.

This approach does not allow a corticotomy in between each tooth, a condition that produces accelerated cotricotomias. Patients who underwent the surgical procedure were periodontally healthy.

This technique has proven to be effective, but also invasive: 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 corticotomiad for orthognathic surgery Fig.

This manuscript reports three cases treated with a novel, flapless approach for minimally invasive rapid orthodontic MIRO.

Ortodoncia Rápida con Corticotomías Piezoeléctricas sin Colgajo: Primeras Experiencias Clínicas

It was necessary to open the top tube of the maxillary second premolars to allow a step to be made on the steel wire in the apical direction, which would not interfere in the intrusion movement. The increased cellular activity is transitory and thus, requires orthodontic setting every two weeks.

In daily clinical routine, overerupted maxillary molars are frequently observed. Intrusion of overerupted upper first molar using two orthodontic miniscrews.

Although effective, these techniques are also quite invasive in nature, requiring the elevation of buccal and lingual full-thickness flaps with extensive decortications of the buccal and lingual alveolar bone. Ortodoncai the maxillary second molars and pre-molars, a double tube was welded to allow insertion of the stainless steel archwire.

Ortodoncia Facilitada por Corticotomía | Periounitec

Revascularization and bone healing after maxillary corticotomies. Regulation of bone volume and the regional acceleratory phenomenon in normal bone. The pulp vitality of these teeth was evaluated by thermal and electric tests. A synthesis of scientific perspectives. After careful irrigation, the flap was repositioned and appropriately sutured.

Accelerated osteogenic orthodontics technique: Selective alveolar corticotomy to intrude overerupted molars. Minimally invasive rapid orthodontics MIRO is ortodonfia procedure that shows evident reduction of orthodontic treatment time, avoiding the adverse effects of accelerated orthodontics reported in the literature. Individual with overerupted maxillary molars: It is a surgical procedure corticotomisa which only the cortical bone is cut, drilled or mechanically altered Bhattacharya et al.

A year-old girl came to the clinic asking for orthodontic assessment and rapid treatment. MIRO reduce el tiempo de tratamiento de ortodoncia, evitando los efectos adversos reportados por la ortodoncia acelerada.

Ortodoncia Facilitada por Corticotomía

Rapid orthodontic tooth movement aided by alveolar surgery in beagles. This innovative technique was tested in this animal model.

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.

Surgical operations on the alveolar ridge to correct occlusal abnormalities. Although excessive and prolonged orthodontic treatment might result in loss of pulp vitality Hamersky et al. Evaluation of the positive and negative responses to cold and electrical pulp tests. Tooth movements in foxhounds after one or two alveolar corticotomies.

Expansion ortopedica maxilar con ortodoncia osteogenica periodontalmente acelerada.

Vertical cuts were made in the cortical bone in the mesial, distal and interproximal regions, beginning mesial and distal 2 to 3 mm apically prtodoncia relation to the alveolar crest and extending interproximal 1 to 3 mm above the root apex.

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. Selective alveolar corticotomy is an alternative to accelerate the orthodontic treatment in adults.

The excessive and prolonged orthodontic treatment might result in loss of pulp vitality.

Surgical procedures have been developed to reduce overall orthodontic treatment times, these techniques include 1 osteotomy Koudstaal et al. Rapid treatment of Class II malocclusion with piezocision: She presented a Class I, open bite malocclusion, high palate, and maxillary arch compression Fig.

This method was chosen because it was simple and was not influenced by other mechanisms to obtain the movement of intrusion, as would occur with the use of orthodontic mini-implants. Images of a representative individual with the orthodontic apparatus may be observed in Figure 2.

Pretreatment frontal and occlusal view.

This result agrees with the findings of Wilcko etal. Therefore, the aim of this pilot study was to evaluate the impact of selective alveolar corticotomy associated with orthodontic intrusion on pulp vitality of overerupted maxillary first molars. Six individuals with extruded maxillary first molars were randomly selected to croticotomias corticotomy as coadjuvant therapy for intrusion.

B Vertical corticotomies were performed following the gingival incision trace. Individuals with overerupted maxillary first molars, and who had maxillary teeth that would allow assembly of the orthodontic appliance required for intrusion of the extruded maxillary first molars were included in the study. 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.

Corticotomas before surgery, the patients rinsed with chlorhexidine 0. After this procedure, the bone tissue initially is in a biological state called the Regional Acceleratory Phenomenon RAPcharacterized by an increased perfusion, bone turnover and decreased bone density, followed by intense remineralization and production of young bone tissue, which will be replaced by mature and more compact bone tissue Frost, ; Gantes et al.
