The proposed treatment plan was orthodontic treatment and maxillary corticotomy. On the maxillary second molars and pre-molars, a double tube was welded to allow insertion of the stainless steel archwire.
However, these techniques have not been widely embraced by the dental community since they require extensive corticoto,ias thickness flap elevation and in cases 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.
The selective alveolar corticotomy was shown to be an effective and safe auxiliary method to intrude overerupted maxillary first molars.
Images of a representative individual with the orthodontic apparatus may be observed in Figure 2. Speedy surgical-orthodontic treatment with temporary anchorage devices as an alternative to orthognathic surgery.

Noteworthy morbidity associated with osteotomy includes the risk of lost tooth vitality, avascular necrosis of the osseous block. Surgically facilitated orthodontic treatment: 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.
Although effective, corticotojias techniques are also quite invasive in ortodonfia, requiring the elevation of buccal and lingual full-thickness flaps with extensive decortications of the buccal and lingual alveolar bone. 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. During follow-up period, healing was uneventful Figs.
This surgically facilitated orthodontic treatment did not promote pulp damage. This study aimed to evaluate the impact of selective alveolar corticotomy associated with orthodontic intrusion on pulp vitality of overerupted maxillary first molars. However, this procedure is complex, and it is also quite difficult to be sure that the graft is placed under the periostium.
The increased cellular activity is transitory and thus, requires orthodontic setting every two weeks. New therapeutic modalities to modulate orthodontic tooth movement. Rapid Orthodontics with Flapless Piezoelectric Corticotomies: After this procedure, the bone tissue initially is in a biological state called the Regional Acceleratory Phenomenon RAPcharacterized by an increased perfusion, bone turnover rotodoncia 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.
Benign paroxysmal vertigo secondary to placement of maxillary implants using the alveolar expansion technique with osteotomes: The same ocrticotomias two months after piezoelectric corticotomies. She presented a Class I, open bite malocclusion, high palate, and maxillary arch compression Fig. At four months, she showed significant advances and the crowding was resolved at eight months, improving function and aesthetics.
Regulation of bone volume and the regional acceleratory phenomenon in normal bone. Enhanced effect of combined treatment with corticotomy and skeletal anchorage in open bite correction.
Surgery was performed under local anesthesia. Surgical operations on the alveolar ridge to ccorticotomias occlusal abnormalities. 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. However, age increase difficult orthodontic tooth movement due to a reduction in the proliferation of the clrticotomias ligament cells, in the synthesis of organic matrix and collagen, in alkaline phosphatase activity and in cell differentiation, which also leads to a decrease in the number of osteoblast precursor cells Ren et al.
Vertical cuts were made in the cortical bone in the mesial, distal and interproximal regions, beginning mesial and distal 2 to 3 mm apically in relation to the alveolar crest and extending interproximal 1 to 3 mm above the root apex.
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.
Comparison of corticotomy-facilitated vs standard tooth-movement techniques in dogs with miniscrews as anchor units. Selective alveolar corticotomy to intrude overerupted molars.

This report proposes a technique that uses metal markers as radiographic references or guides for accurate corticotomy by means of intraoral periapical radiographies. Rapid canine retraction through distraction of the periodontal ligament.
Although excessive and prolonged orthodontic treatment might result in loss of pulp vitality Hamersky et al.
