“…Os MI tem se mostrado eficazes em movimentos dentários tridimensionais: antero-posterior, transversal e vertical, seja na retração de dentes anteriores ou de todo arco, dente único ou intrusão de todo arco, distalização de caninos e pré-molares, correção de plano oclusal assimétrico, desvio de linha média, ancoragem para cantiléver em tracionamento de caninos inclusos, distalização unilateral e ainda promover alterações esqueléticas nas relações maxilomandibulares mantendo ancoragem absoluta [2][3][4] .…”

Os mini-implantes (MI) podem ser considerados a maior revolução da ortodontia moderna, são dispositivos temporários que dependem de retenção mecânica de sua estrutura metálica na cortical óssea e nem sempre osseointegram, eles podem ser instalados entre as raízes dos dentes e também na região extra-alveolar. MI instalados na região extra-alveolar apresentam diversas vantagens em relação aos inter-radiculares e tem se mostrado eficazes em movimentos dentários tridimensionais: antero-posterior, transversal e vertical. A localização ideal para inserção de MI na maxila é na crista infrazigomática (IZC), sobre o primeiro molar superior a 14/16 mm acima do plano oclusal e um ângulo de 55/70°. Os parafusos devem ser carregados imediatamente após a instalação, a quantidade de força inicial deve ser entre 150 e 200 g e gradualmente aumentada até 350 g. Os MI inseridos na IZC é o seu tamanho, por serem mais longos (> 10 mm) e com maior diâmetro apresentam maior área de retenção, permitem diversos movimentos ao mesmo tempo, otimizando o tempo de tratamento ortodôntico. A colaboração do paciente nestes casos, é somente com a higienização da área onde está inserido o MI, vale ressaltar que se ele for instalado sobre a gengiva livre as chances de insucesso aumentam significativamente. A ortodontia atual sofreu uma revolução com o uso de mini-implantes, devido ao baixo custo, fácil instalação e possibilidades de tratamentos mais fáceis e rápidos, especialmente em casos desafiadores e complexos. Ainda há medo por parte do ortodontista a fazer uso destes dispositivos, geralmente por não domínio da técnica.

“…Although according to some authors [5], sinus penetration depth within 1 mm is advocated for mini-implant anchorage, to avoid this complication, adequate bone depth should be available at the site of mini-screw insertion. Typically, IZC mini-screws are longer than intra-radicular mini-implants and manufactured in two dimensions: 2 mm diameter and 12 mm or 14 mm length (a 14 mm screw is recommended in the case of thick soft tissue in the buccal vestibule) [6]. As stated by the literature, a minimum of 6 mm of the bone is necessary to provide sufficient stability of the IZC during orthodontic treatment [7,8].…”

Infrazygomatic crest (IZC) mini-implants are frequently used as an absolute anchorage when intrusive or distally directed forces are required during orthodontic treatment. The aim of the present study was to evaluate the thickness of the IZC area in Polish patients as well as to assess dependency between bone availability, sex, and age. The study material was 100 cone beam computed tomography scans (CBCT) of the maxilla of patients of the University Dental Clinic in Krakow (50 men and women each). IZC bone thickness was measured at nine different points. The biggest bone thickness was recorded in the interdental space between the first and second molar at the height of 12 mm (6.03 ± 2.64 mm). The thinnest bone depth was localized at the level of the mesial root of the first molar, 16 mm above the occlusal plane (2.42 ± 2.16). There was a significant and negative correlation between bone thickness and age in the case of measurements taken buccally to the first molar. Only two out of nine measurements showed a sex dependency (points I2 and I3). Considering vertical and sagittal dimensions, the most favorable conditions for IZC mini-implant placement were found interdentally, between the first and second molar, 12 mm above the occlusal plane.

Distalization of the maxillary molars is among the most commonly employed nonextraction treatment strategies for angle Class II malocclusion. This approach is primarily recommended for subjects with dentoalveolar maxillary protrusion or minor skeletal abnormalities. A case of a 17-year-old Hispanic male patient with Class II skeletal base with Class II end on canines and molars, upper anterior crowding, severe overjet, and moderate overbite is hereby reported. He refused extraction; therefore, he was offered full single upper arch distalization using subzygomatic temporary anchorage devices (TADs). After 11 months of retraction, the TADs were removed and it was observed that the overjet and overbite were now within normal values and midline shift was also corrected. Satisfactory leveling and alignment, alleviation of crowding, and Class I molar and canine relationship were achieved. The aim of this case report was to describe full single arch distalization using subzygomatic TADs in a patient with Class II skeletal, molar, and canine relationships.
