“…Similar observation of mesialization and extrusion of the upper molars and extrusion after use of the FFA has been reported. 10,11,[24][25][26] This may be attributed to the mechanics involved during finishing of treatment after removal of the FFA or natural tendency of teeth to drift mesially and occlusally with growth. 27 The dentoalveolar correction was achieved primarily by protraction of the lower molars and proclination of lower incisors in both groups under the mesially directed force from the FFA.…”

“…5 Of all appliances, fixed functional appliances (FFAs) are gaining popularity because compliance may be better than removable appliances. 6 Class II correction with a FFA is a combination of skeletal and dentoalveolar changes, 7,8 which include restraining maxillary growth, dubbed as the ''headgear effect,'' 8 retroclination of maxillary 9 and proclination of mandibular incisors, 9-11 distalization of upper and mesial movement of lower molars, 10,11 along with clockwise rotation of the occlusal plane. 9 Historically, FFAs are advocated towards the end of the pubertal growth spurt.…”

Objective: To compare the dentoskeletal effects and treatment efficiency of the Twin Force Bite Corrector (TFBC) appliance in Class II correction of patients treated before or after the pubertal growth spurt. Materials and Methods: Forty-one normodivergent Class II patients treated with the TFBC appliance were divided into two groups based on their cervical vertebral maturation stage (CVMS). Group 1 (G1) consisted of 23 patients (mean age 12.44 6 1.59 years) where treatment was initiated before the pubertal growth spurt (CVMS I and II), while group 2 (G2) consisted of 18 patients (mean age 13.76 6 1.44 years) where treatment was started after the pubertal growth spurt (CVMS III to V). Dentoskeletal measurements were made on lateral cephalograms taken before (T1) and after orthodontic treatment (T2). Results: During treatment, G1 had significantly greater skeletal correction than G2, with more dentoalveolar effects being observed in G2 than G1. However, on comparing both groups at the end of treatment (T2) when growth is complete, no differences in the parameters measured were observed. Overall, treatment time was significantly longer for G1 (3.67 6 1.45 years) compared to G2 (2.75 6 1.07 years). Conclusions: There is no difference in overall dentoskeletal effects obtained at the end of treatment by the TFBC appliance in normodivergent prepubertal vs postpubertal patients. However, treatment efficiency based on treatment timing is significantly greater for the postpubertal group. (Angle Orthod. 2013;83:718-727.)

“…A pesar de su modo de acción distinto, el Jasper jumper tiene efectos similares al Herbst, incluyendo la restricción del crecimiento anterior del maxilar, la retracción dentoalveolar de la dentición maxilar, el movimiento distal de los molares maxilares, la protracción dentoalveolar mandibular, la protrusión mandibular y la mejoría en las relaciones maxilomandibulares, con la ventaja de permitir movimientos de lateralidad de la mandíbula, buena cooperación y fácil higiene oral; sin embargo, sigue siendo un aparato débil y los efectos ortopédicos de aumento en el crecimiento mandibular no se han comprobado [55].…”

“…Los efectos esquelé-ticos en el maxilar se reducen a generar una resistencia al crecimiento hacia adelante del maxilar [55,59,60]; a nivel mandibular se ve un incremento no muy significativo en la longitud mandibular con una mejoría en las relaciones maxilomandibulares [55]. Dentro de los efectos dentales se encuentran una disminución del overjet y el overbite gracias a la retroinclinación de incisivos superiores [55,59] y distalización de los molares con inclinación e intrusión de estos. Los incisivos inferiores se proinclinan e intruyen como efectos indeseables [55] que podrían ser contrarrestados con el uso de brackets con torque coronal negativo.…”

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.
