Movimentos ortodônticos realizados com alinhadores in-house possuem detalhes e particularidades que os diferem da mecânica ortodôntica convencional multi-bráquetes e que precisam ser respeitados pelo ortodontista na busca pela maior previsibilidade, eficácia e eficiência dos resultados. Detalhes quanto ao tipo de movimento programado para cada dente, controle de ancoragem, hierarquização das movimentações, peculiaridade da mecânica das variadas composições dos plásticos e tipos de attachments são apresentados nesta segunda parte do tutorial sobre a fabricação de alinhadores in-house.

Osteogenesis imperfecta is a rare genetic disorder involving abnormal type I collagen composition that compromises bone and collagen-rich tissues. Individuals with Osteogenesis imperfecta exhibit oral and systemic abnormalities, including dentinogenesis imperfect. The purpose of the review is to report a clinical case of a nine-year-old boy diagnosed with Osteogenesis Imperfecta type III, focusing on dental and occlusal aspects. The case report was developed at the outpatient clinic at the School of Dentistry of the Federal University of Minas Gerais, in Southeastern of Brazil. The clinical oral examination revealed Angle Class III malocclusion and anterior crossbite. It was also observed the presence of dentinogenesis imperfect in both primary and permanent teeth. Radiographic analysis showed the presence of completed obliterated pulp chambers in both dentitions. Dental treatment included oral hygiene counseling, dental extraction, fluoride therapy and restorations. The child was followed up for a period of six years and then referred to the orthodontic outpatient clinic at the same university for the treatment of malocclusion. Early dental care is important to the prevention or interception of oral diseases, such as dentinogenesis imperfect and malocclusion, as well as the improvement of dental esthetics in cases of Osteogenesis Imperfecta.
