Efficacy of Myofunctional Therapy in Class II Patients With Functional Orthopedic Appliances. ECA

Randomized clinical trial , with a sample of 60 children with atypical swallowing, class II and with SN1 orthopedic appliances these patients were randomly divided into, group 1: 30 patients with SN1 orthopedic appliances and myofunctional therapy and group 2: 30 patients with SN1 orthopedic appliances and without myofunctional therapy.

Randomized clinical trial with two parallel arms, on a sample of 60 children with atypical swallowing, class II and with SN1 orthopedic appliances, these patients were randomly divided into, group 1: 30 patients with SN1 orthopedic appliances and myofunctional therapy and group 2: 30 patients with SN1 orthopedic appliances and without myofunctional therapy for the study. Both groups carried out the evaluation of the protocol that included: 1) evaluation of the dental occlusion class and skeletal classification 2) swallowing function test using the Payne technique; 3) Mioscaner analysis to measure perioral forces, i.e. tongue extension force, lip pressure, masseter contraction force.
