“…This decrease was probably related to remission of pain symptoms caused by dental compression during sleep, subluxation of the mandibular condyles, headaches, cervical pain and osteoarthrosis [14], and was likely due to posture changes during use of the apparatus leading to clinical improvement. Bone discrepancy remodeling and articular positioning after 12 months of functional orthopedics appliance use reestablished the functionality of the masticatory muscles [15].…”

This case report evaluated electromyographic activity of the masseter and temporalis muscles and molar bite force, before and after with functional orthopedic. A 65 years woman presenting with orofacial pain symptoms, cervical tension, condyle subluxation and osteoarthrosis. The patient was diagnosed with temporomandibular dysfunction and treated with use of a Simões Network 9 modified type functional maxillary orthopedics appliance. The Myosystem BR1 apparatus was used to analyze the electromyographic activity of the masseter and temporalis muscles. The maximum molar bite force was measured with the digital dynamometer (Kratus). This study showed increased EMG activity of the masseter and temporalis muscles in postural conditions of mandible and molar bite force after 12 months of treatment. After twelve months of treatment, the patient had lack of pain symptoms as well as an improvement in the balance of the mastication muscles, as demonstrated by EMG activity and maximum molar bite force.

“…This is a usual active retention alternative employed after using a fixed functional appliance. 10 , 32 Because use of the MPA appliance was of 9 months and treatment times were relatively long in both groups, the additional time with Class II elastics use as active retention should, most likely, assure good stability of the anteroposterior correction. 10 , 23 Nevertheless, this issue should be investigated in future studies.…”

Objective: The aim of this study was to compare the skeletal, dental, and soft tissue effects of the Mandibular Protraction Appliance (MPA) application in adolescent and adult Class II malocclusion patients. Methods: The sample comprised the pretreatment and posttreatment lateral cephalograms of 39 subjects presenting Class II malocclusion treated with the MPA and fixed appliances. Sample was divided into two groups: Group 1 comprised 23 subjects (10 male; 13 female), at a mean pretreatment age of 11.75 years, with a mean treatment time of 3.32 years; Group 2 included 16 subjects (7 male; 9 female), at a mean pretreatment age of 22.41 years, with a mean treatment time of 4.24 years. Intergroup comparison of the initial and final stages and treatment changes between the groups was performed with t tests, at p< 0.05. Results: The adults showed less significant amounts of skeletal, dentoalveolar and soft tissue changes than the adolescents. There was significantly greater palatal tipping of the maxillary incisors and retrusion of the upper lip in the adolescents. The adult group showed greater mandibular incisor proclination in the posttreatment stage. Conclusion: Adult patients treated with MPA showed less significant amounts of skeletal, dentoalveolar and soft tissue changes than adolescents.

“…Con estos hallazgos se demuestra que los pacientes no presentan dificultad en adaptarse a la nueva posición mandibular después de 6 meses de tratamiento activo. Sin embargo, es importante aclarar que no todos los estudios presentan uniformidad en cuanto al diseño vertical de los aparatos empleados y por tanto se pueden encontrar aumentos y disminuciones de las actividades electromiográficas [34].…”

“…Es un aparato más flexible y elástico que el Herbst, en el que la mandíbula puede realizar fácilmente movimientos laterales; los pacientes pueden cerrar en relación céntrica, morder repetidamente y deglutir, resultando en una mandí-bula más estable [34]. La inserción del Forsus crea una reprogramación motora resultando en una adaptación postural que permite la respuesta de crecimiento [34].…”

Resumen. La mayoría de los pacientes con maloclusión clase II esquelética presentan posición retruida de la mandíbula. El término aparato funcional se refiere a aparatos fijos o removibles diseñados para alterar la posición mandibular sagital y verticalmente, resultando en cambios esqueléticos, ortodónticos y ortopédicos. A pesar de su larga historia, los aparatos funcionales continúan siendo controversiales en su uso, efectividad y modo de acción. Esta revisión permitirá conocer las diferentes alternativas de tratamiento para la maloclusión clase II esquelética causada por retrusión mandibular, entre los que están Bionator, Twin Block, Herbst, Jasper Jumper, Forsus, mara y Advansync, de los cuales se explicará su modo de acción, sus efectos a nivel dental y esquelético y el tiempo de tratamiento óptimo para conseguir estabilidad.Palabras clave: avance mandibular, maloclusión de Angle clase II, mandíbula, retrognatismo. Mandibular Advancement Apparatus: Myth or Reality?Abstract. Most patients with skeletal Class II malocclusion present a retruded position of the mandible. Functional appliances are fixed or removable appliances designed to alter the sagittal and vertical mandibular position, resulting in orthodontic and orthopedic skeletal changes. Despite their long history, functional appliances remain controversial in their use, effectiveness and mode of action. This review will reveal the different treatment options for skeletal Class II malocclusion caused by mandibular retrusion, such as: Bionator, Twin block, Herbst, Jasper jumper, Forsus, mara and Advansync; it will also explain the mode of action, skeletal and dental effects and optimum treatment time for stability.

Neuromuscular adaptations with flexible fixed functional appliance – a 2-year follow-up study

Abstract: The anterior temporalis and masseter muscles clearly responded to appliance therapy. The neuromuscular adaptation documented after 6 months of treatment remained stable over a 24-month observation period.
