Hypodontia is the congenital absence of one or more teeth and may affect permanent teeth. Several options are indicated to treat hypodontia, including the maintenance of primary teeth or space redistribution for restorative treatment with partial adhesive bridges, tooth transplantation, and implants. However, a multidisciplinary approach is the most important requirement for the ideal treatment of hypodontia. This paper describes a multidisciplinary treatment plan for congenitally missing permanent mandibular second premolars involving orthodontics, implantology and prosthodontic specialties.

OBJETIVO: este artigo tem como objetivo abordar as características do tratamento ortodôntico associado a uma atuação odontogeriátrica, pois devido a um aumento da expectativa de vida, um maior número de pacientes idosos tem procurado tratamento odontológico para uma reabilitação estética e/ou funcional. METODOLOGIA: através de uma avaliação de dados presentes na literatura são abordados fatores como enfermidades sistêmicas, uso de medicamentos, condição da saúde bucal, quantidade de osso alveolar, motivação do paciente e estabilidade oclusal após a terapia ortodôntica. Para exemplificar o tratamento ortodôntico no paciente idoso são apresentados dois casos clínicos. CONCLUSÕES: o tratamento ortodôntico representa uma intervenção viável na atuação odontogeriátrica, desde que realizado com forças suaves, considerando as limitações de cada caso e respeitando as características inerentes a esta atuação.

OBJECTIVE: to approach the characteristics of the orthodontic treatment in aged patients, because the increase of life expectancy resulted in a bigger number of these kind of patients looking for orthodontic treatment. METHODS: an evaluation of the literature show a series of factors as: systemic disease, medicine utilization, condition of the buccal health, amount of alveolar bone, patients’ motivations and occlusal stability after the orthodontic therapy. To demonstrate the orthodontic treatment in the aged patient two clinical cases are presented. CONCLUSIONS: the orthodontic treatment represents a viable intervention in the aged patients, since that carried through with soft forces, considering the limitations of each case and respecting the inherent characteristics to these patients.

OBJECTIVE: The aims of this study were to compare the prevalence of temporomandibular disorders (TMD) in individuals submitted to either orthodontic or ortho-surgical Class III malocclusion treatment and to assess the influence of occlusal aspects on TMD severity. MATERIAL AND METHODS: The sample consisted of 50 individuals divided into two groups, according to the type of treatment (orthodontic or orthodontic with orthognathic surgery). The presence of signs and symptoms of TMD was evaluated by an anamnestic questionnaire and a clinical examination, including TMJ and muscle palpation, active mandibular range of motion, joint noises and occlusal examination. RESULTS: Based on the anamnestic questionnaire, 48% had no TMD, 42% had mild TMD and 10% had moderate TMD. The presence and severity of TMD did not show any relationship with the type of orthodontic treatment (p>0.05). The chi-square test showed a positive association (p<0.05) between TMD and non-working side occlusal interferences. CONCLUSION: Based on the methodology used and the results obtained, it may be concluded that Class III orthodontic treatment was not associated with the presence of TMD signs and symptoms and the non-working side contacts can be occlusal factors of risk. There was no significant difference in TMD prevalence between the studied groups (orthodontically treated patients and patients treated with orthodontics followed by orthognathic surgery).
