Verticalização do segundo molar inferior com mini-implante em paciente adulto - relato de caso clínico / Lower second molar uprighting using mini-implants in adult patients - a case report

Muitos pacientes adultos procuram tratamento ortodôntico atualmente por motivos estéticos, funcionais e também por indicação de protesistas para possibilitar a reabilitação oral. Objetivo: o presente trabalho se propõe a relatar um caso clínico de paciente do gênero feminino, com perda de primeiro molar inferior e consequente inclinação mesial e perda de espaço protético. Relato de caso: foi realizado movimento de verticalização do segundo molar inferior em paciente adulto com auxílio de mini-implante para ancoragem para possibilitar posterior reabilitação. Conclusão: o tratamento beneficiou a paciente, pois teve a correção do segundo molar inferior inclinado em apenas três meses, além da visível neoformação de tecido ósseo na região mesial do mesmo dente após seis meses, resultando em uma melhor condição parainstalação de um futuro implante na região do dente ausente.

Many adult patients seeking orthodontic treatment currently for aesthetic reasons, functional and also prosthetic indication to enable oral rehabilitation. Objective: This study aims to report a case of female patient with absence of the first molar, mesial inclination of the second molar and consequent loss of prosthetic space. Case report: the second molar in an adult patient was uprigthed using miniscrew as anchorage system to enable subsequent rehabilitation. Conclusion: It can be concluded that the patient was benefited with this type of treatment, as the uprigthing of the second inclined molar occurred in just three months, beyond the visible formation of new bone tissue in the mesial region of the same tooth after six months, resulting in a better condition for installing a future implant in the missing tooth region.

Orthopedic treatment of Class III malocclusion with rapid maxillary expansion combined with a face mask: a cephalometric assessment of craniofacial growth patterns

OBJECTIVE: The aim of this prospective study was to assess potential changes in the cephalometric craniofacial growth pattern of 17 children presenting Angle Class III malocclusion treated with a Haas-type expander combined with a face mask. METHODS: Lateral cephalometric radiographs were taken at beginning (T1) and immediately after removal of the appliances (T2), average of 11 months of treatment. Linear and angular measurements were used to evaluate the cranial base, dentoskeletal changes and facial growth pattern. RESULTS: The length of the anterior cranial base experienced a reduction while the posterior cranial base assumed a more vertical position at T1. Some maxillary movement occurred, there was no rotation of the palatal plane, there was a slight clockwise rotation of the mandible, although not significant. The ANB angle increased, thereby improving the relationship between the jaws; dentoalveolar compensation was more evident in the lower incisors. Five out of 12 cases (29.41%) showed the following changes: In one case the pattern became more horizontal and in four cases more vertical. CONCLUSIONS: It was concluded after a short-term assessment that treatment with rapid maxillary expansion (RME) associated with a face mask was effective in the correction of Class III malocclusion despite the changes in facial growth pattern observed in a few cases.

Intervenção precoce na mordida aberta anterior / Early intervention in anterior open bite

A mordida aberta anterior é uma anomalia complexa cujas características próprias envolvem a função, a estética, além das alterações dentárias e esqueléticas. Sua principal característica é a presença de um trespasse vertical negativo, existente entre as bordas incisais dos dentes anteriores superiores e inferiores, quando a mandíbula está em posição cêntrica. O objetivo deste trabalho é apresentar, por meio de um relato clínico, a intervenção precoce de uma mordida aberta anterior funcional associada ao hábito de sucção da chupeta, que foi tratada com grade palatina na fase de dentição decídua. Os resultados clínicos demonstraram a viabilidade e a eficiência da realização de uma terapia, mesmo em crianças de pouca idade, em curto prazo de tempo.

The anterior open bite is a complex anomaly, with its own characteristics, such as aesthetic, function, as well as dental and skeletal changes. Its main characteristic is the presence of a negative vertical crossing existing between the incisor borders of the upper anterior and lower anterior teeth, when the jaw is in centric position. The objective of this study is to present, through a clinical case analysis, the precocious intervention of one anterior open bite case associated with the habit of the pacifier, that was dealt with palatal crib in the phase of primary dentition. The clinical results demonstrated the viability and efficiency of the therapy in young children in short term.
