“…The former has stood the test in many recent studies [21,22,33,[37][38][39][41][42][43][44][45][46]. MR imaging is a technique using static and dynamic magnetic fields to depict in detail both bones and soft-tissue structures.…”

Functional jaw orthopedics for correction of skeletal Class II with the rigid fixed FMA leads to side-effects reflected in the disc-condyle relationship in the temporomandibular joints: no adverse effects were observed in joints presenting an initial physiological disc-condyle relationship, whereas the disc position may improve in joints with initial partial or total anterior disc displacement. In comparison with the baseline findings, we observed no post-treatment restriction in the extent of maximum mouth opening, protrusion, and left and right laterotrusion. Maximum active retrusion increased due to the treatment. MR imaging and MSA only partly cover the same aspects of temporomandibular joint diagnostics.

“…Treatment with functional appliances can produce extensive remodeling and anterior relocation of the mandibular fossa [31]. Functional treatment changes the position of the mandibular condyle within the mandibular fossa [32]. Thus, there can be changes in the posture of the mandible without modifying its size.…”

There is still controversy regarding the efficacy of functional appliances when treating malocclusion at an early age. Although a good outcome from treatment is important, the stability of the results over time becomes a major concern. This paper presents the results of three open bite cases treated with the Bimler type-A appliance in the mixed dentition. The open bite cases presented here demonstrate stability of the treatment results for more than 14 years without active retention after the active treatment period. A comparison between these cases and those performed with an elastic functional appliance, and the action of that appliance on tongue posture, are discussed. The cases presented in this paper support treating malocclusions at an early age with functional appliances. The features of the appliance chosen to treat an open bite early can be a key factor for the results and stability.

“…1,3 Among orthopedic appliances, the Herbst is commonly utilized as a means of maintaining the mandible in a constant anterior position. [1][2][3] Although various investigations have shown [1][2][3][4][5][6][7] the efficiency of this method of treatment, the mechanism by which the temporomandibular joint (TMJ) responds to the treatment is controversial. [1][2][3]8 A recent study evaluated patterns of stress generation in the TMJ after mandibular protraction by using a three-dimensional finite element method.…”

; Má rcio Abrahã o d ABSTRACT Objective: To determine the changes in the position and form of the temporomandibular joint articular disc in adolescents with Class II division 1 malocclusion and mandibular retrognathism treated with the Herbst appliance (phase I) and fixed orthodontic appliance (phase II). Materials and Methods: Thirty-two consecutive adolescents went through phase I of treatment and 23 completed phase II. The temporomandibular joints were evaluated qualitatively by means of magnetic resonance images at the beginning of treatment (T1), during phase I (T2), at the end of phase I (T3), and at the end of phase II (T4). Results: Significant changes in disc position were not observed with the mouth closed between T1 3 T3 (P 5 .317), T3 3 T4 (P 5 .287), or T1 3 T4 (P 5 .261). At T2, on average, the disc was positioned regressively. With the mouth open, no difference was observed between T1 3 T3 (P 5 .223) or T1 3 T4 (P 5 .082). We did observe a significant difference between T3 3 T4 (P , .05). Significant changes in the disc form were found with the mouth closed between T1 3 T2 (P , .001) and T2 3 T3 (P , .001). Conclusions: At the end of the two-phase treatment, in general terms, the position and form of the initial articular discs were maintained; however, in some temporomandibular joints some seemingly adverse effects were observed at T4.
