Examination of temporomandibular disorders in the orthodontic patient: a clinical guide
The possible association between orthodontic treatment and temporomandibular disorders (TMD) is a topic of great interest in the current literature. The true role of orthodontic therapy on the etiology of TMD, however, is still uncertain. From the clinical prospective, a thorough examination of the stomatognathic system is always necessary in order to detect possible TMD signs and symptoms prior to the beginning of the orthodontic therapy. Caution should be exercised when planning, performing and finalizing orthodontics, especially in patients who with history of signs and symptoms of TMD. The clinician must always eliminate patient's pain and dysfunction before initiating any type of orthodontic mechanics. Muscle incoordination, unstable disc-condyle relationship and bone alterations are usual TMD conditions that can interfere with the presenting occlusal relationship. This article reviews these aspects and presents a detailed clinical guide for the examination of the orthodontic patient, considering aspects related to facial pain and dysfunction
Estabilidade a longo prazo do tratamento da mordida aberta anterior na dentadura mista: relato de caso clÃnico
Apresentou-se um relato de caso clÃnico de mordida aberta anterior, tratada em dentadura mista, demonstrando uma das possÃveis formas de tratamento, capaz de interferir no crescimento e redirecionar seus vetores. Os protocolos ortodônticos e ortopédicos utilizados foram a expansão lenta da maxila, utilizando grade palatina soldada a um expansor bihélice, com tração alta na mandÃbula, num perÃodo diário de 16 horas. Oito anos de estabilidade foram alcançados, explicados pelo fato de o tratamento ter sido conduzido no momento oportuno do desenvolvimento, o que estabeleceu equilÃbrio entre os músculos peribucais, em conjunto com o perÃodo final do crescimento. A combinação do tratamento ortodôntico e ortopédico foi necessária para se evitar a necessidade de tratamento cirúrgico.A clinical case with anterior open-bite, treated in the mixed dentition, is presented. This approach demonstrates one of the possible approaches of treatment, which is capable of interfering with growth and redirecting its vectors. Orthodontic and orthopedic methods were used, consisting of slow maxillary expansion, through a fixed palatal crib soldered in a bi-helix appliance, and high-pull traction on the mandible for 16 hours a day. After eight years of follow-up, stable outcomes were accomplished. These results may be explained by the fact that treatments were performed at the appropriate period of development, thus establishing perioral muscular equilibrium, matching the final period of facial growth. The combination of orthodontic and orthopedic treatments was necessary to prevent the need of further orthognathic surgery treatment
