Corticotomias alveolares na Ortodontia: indicações e efeitos na movimentação dentária

Abstract

Introduction:The systematic search for increased efficiency in orthodontic treatment is shared by several areas of orthodontics. Performing alveolar corticotomies shortly before the application of orthodontic forces has been suggested as a method to enhance tooth movement and, consequently, orthodontic treatment as a whole. Objective: This article reviews the historical perspective of this therapeutic approach, presents and illustrates with clinical cases its main indications and finally discusses the biological reasons underlying its use.

Maxillary posterior intrusion with corticotomy-assisted approaches with zygomatic anchorage—a finite element stress analysis

“…Corticotomy has been shown to facilitate orthodontic tooth movement by regional acceleration phenomenon, which results in healing of the injured bone by an increase in the rate of bone turnover [33]. The healing stimulus causes transient osteopenia in alveolar bone, leading to decreased resistance to tooth movement [18, 33]. The increased stress at the cancellous bone might show that the mechanical responses of dentoalveolar structures can be affected by corticotomy cuts during intrusion.…”

“…In this respect, the introduction of corticotomy-assisted orthodontics provided new solutions to some limitations in orthodontic tooth movement by a localized area of increased bone turnover through a controlled surgical damage [15–17]. The controlled surgical injury causes a temporary and reversible decrease in regional bone density, which reduces the resistance to tooth movement, thus enabling rapid tooth movement at the early stages [18]. The additional advantages of corticotomy-assisted orthodontics has been described as increased treatment efficiency, less need for extraoral appliances, less relapse [19], and less risk of root resorption [20].…”

Histological evaluation of the effects of corticotomy on induced orthodontic movement in rats

“…2017 Nov-Dec; 46 (6): [368][369][370][371][372][373] Histological evaluation of the effects... 369 accelerate orthodontic treatment as a whole 1,2 . In this context, there has been an increase in number of studies addressing the matter of Alveolar Corticotomy to increase the velocity of tooth movement This procedure consists in an intentional surgical intervention limited to the cortical portion of the alveolar bone, with no damage to the bone marrow, associated with orthodontic treatment aiming to accelerate dental movement [2][3][4][5] .…”

Avaliação da aceleração do movimento dentário produzido pelas microosteoperfurações nos casos orto-cirúrgicos durante a fase de retração dos dentes anteriores: um ensaio clínico randomizado

“…Atualmente um grande desafio na Ortodontia é diminuir o tempo do tratamento ortodôntico sem comprometer o resultado do mesmo (Uzuner e Darendeliler, 2013;Long et al, 2013;Alikhani et al, 2013;Alikhani et al, 2015;Aksakalli et al, 2016), pois trata-se de uma questão importante para os pacientes (Oliveira et al, 2010;Sakthi et al, 2014;Alfawal et al, 2016), sendo um fator determinante da recusa de muitos deles em iniciar o tratamento ortodôntico (Al-Naoum et al, 2014). Com o objetivo de diminuir o tempo de tratamento sem perder a qualidade dos resultados, a especialidade vem avançando há muito tempo, no sentido de desenvolver dispositivos mais efetivos, aparelhos mais eficientes, mecânicas mais elaboradas, ou ainda envolvendo pacientes para obter o máximo de sua colaboração (Nimeri et al, 2013;Alikhani et al, 2015;Alfawal et al, 2016).…”

“…Para elucidar o procedimento cirúrgico proposto anteriormente, a técnica PAOO, Murphy et al (2009) Após a introdução das corticotomias na comunidade ortodôntica, e pelas dúvidas e incertezas que o procedimento trazia, um artigo descritivo sobre as indicações e efeitos das corticotomias foi publicado por Oliveira et al (2010). No artigo, este procedimento cirúrgico que aumenta a eficiência da movimentação dentária foi descrito em vários aspectos.…”
