These combine bone-healing mechanisms with orthodontic loads to accelerate tooth movement. The patient accepted the treatment and signed an informed consent. 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. The orthodontic results obtained with the minimally invasive technique proposed herein are similar krtodoncia those observed in the literature by Wilko et al.

Rapid canine retraction through distraction of the periodontal ligament. Revascularization and bone healing after maxillary corticotomies. Special care should be taken to carry out the corticotomy towards the orthodontic movement.

According to these authors, the pulp vitality test is crucial to monitor the state of the dental pulp, and the thermal test is considered more accurate for the assessment of pulp vitality than electrical test Han et al.

MIRO also enhances accuracy by relying on radiographic surgical guides that help to make a precise corticotomy avoiding damage to vital structures and teeth. Evaluation was made by means of superimposition of complete cephalometric tracings of the facial structures and the maxilla, originated from lateral radiographs of the face teleradiographs obtained before treatment and after molar intrusion.

The participants corticotlmias examined every 15 days to follow-up the orthodontic intrusion. Accelerating orthodontics by altering alveolar bone density.

The results related to the period of time necessary for the intrusion of maxillary first molars reveal that pulp vitality was not affected by the adopted protocol. The study was conducted in full accordance with the World Medical Association Declaration of Helsinki. Moreover, a minimally invasive flapless procedure is described.

Neither technique is sufficiently accurate because both lack radiographic reference points as guide for the surgical procedure. Regarding the orthodontic movement after selective alveolar corticotomy, some authors reported the absence of pulp damage to teeth undergoing this treatment, but did not describe the type of pulp vitality test used Gantes et al. 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 ortodonvia carried out on extracted teeth.

The reason for the 2 weeks is to maximize the exploitation of the three- to four-month limited window of opportunity following RAP, where the bone is more pliable allowing to move teeth rapidly through the demineralized bone matrix Lee et al. Therefore, the aim of this pilot study ortodoncoa to evaluate the impact of selective alveolar corticotomy associated with orthodontic intrusion on pulp vitality of overerupted maxillary first molars.

C Frontal view immediately after minimally invasive corticotomies.

Expansion ortopedica maxilar con ortodoncia osteogenica periodontalmente acelerada.

This type of problem occurs in the adult population as a corticotommias of early loss of antagonist tooth Oliveira et al. Microanchor mediated upper molar intrusion in deep posterior bite after long-term edentulousness for prosthetic reconstruction with dental implants.

This surgically facilitated orthodontic treatment did not promote pulp damage. The results showed that although some teeth did not respond to the electrical test, all the teeth responded positively to the thermal test.

However, the results of this study should be interpreted considering the small sample used. However, according to Peters et al. Healing of cancellous bone osteotomy in rabbits–Part I: Table I – Pulp vitality assessment.

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.

Evaluation of the positive and negative responses to cold and electrical pulp tests. Vertical cuts were made in the cortical bone in the mesial, distal and interproximal regions, beginning coricotomias and distal 2 to 3 mm apically in relation to the alveolar crest and extending interproximal 1 to 3 mm above the root apex. One day after bracket placement 0. The following were excluded from the sample: Surgical procedures have been developed to reduce overall orthodontic treatment corticotomia, these techniques include 1 osteotomy Koudstaal et al.

Over the years, several surgical techniques have been developed to address this issue and reduce the overall treatment time. She presented a Class I, open bite malocclusion, high palate, and maxillary arch ortofoncia Fig. On the other hand, there is no consensus in the literature about different techniques used for surgery and orthodontics Koudstaal et al. Images of a representative individual with the orthodontic apparatus may be observed in Figure 2. MIRO reduces orthodontic treatment time, avoiding the reported adverse effects of accelerated orthodontics.

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 ortdoncia molars were included in the study.

Orthodontic microsurgery for rapid dental repositioning in dental malpositions. In daily clinical routine, overerupted maxillary molars are frequently observed. Regarding molar intrusion, the protocol adopted promoted intrusions that ranged from 1.

This result agrees with the findings of Wilcko etal. The regional acceleratory phenomenon: New therapeutic modalities fn modulate orthodontic tooth movement. It was necessary to open the top tube of the cortictomias 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 pulp vitality of these teeth was evaluated by corticotomiaw and electric tests.

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. Pulp vitality and histologic changes in human dental pulp after the application of moderate and severe intrusive orthodontic forces.

After this procedure, the bone tissue initially is in a biological state called the Ottodoncia 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.
