RESUMO
OBJECTIVE: The purpose of this study was to compare, by mechanical in vitro testing, a regular 5-hole plate and a long 4-hole plate with a regular 4-hole plate, applied to stabilize a simulated mandibular angle fracture. STUDY DESIGN: The plates from the 2.0-mm titanium-based system were adapted and stabilized passively in the same site in both groups using four screws, 6 mm long. During the resistance-to-load test, the force was applied perpendicular to the occlusal plane at three different points: first molar at the plated side, first molar at the contralateral side, and between the central incisors. RESULTS: The regular 5-hole plates and longer 4-hole plates were superior to the regular 4-hole plates. Furthermore, no statistically significant difference was found between the regular 5-hole plates and long 4-hole plate. CONCLUSIONS: The length and shape of plates did not interfere with the effectiveness to stabilize the fragments.

O lábio duplo é uma alteração da mucosa labial presente com maior frequência no lábio superior, podendo ser de origem congênita ou traumática. O tratamento de escolha deve ser o cirúrgico, com finalidade estética e funcional. Neste trabalho é apresentado um caso de lábio duplo em um paciente de 35 anos de idade onde a exérese do tecido hiperplásico foi realizada com total satisfação do paciente no pós-operatório.
