ABSTRACT Introduction: Considering the large number of fixed functional appliances, choosing the best device for your patient is not an easy task. Objective: To describe the development of fixed functional appliances as well as our 20-year experience working with them. Methods: Fixed functional appliances are grouped into flexible, rigid and hybrid. They are different appliances, whose action is described here. Four clinical cases will be reported with a view to illustrating the different appliances. Conclusions: Rigid fixed functional appliances provide better skeletal results than flexible and hybrid ones. Flexible and hybrid appliances have similar effects to those produced by Class II elastics. They ultimately correct Class II with dentoalveolar changes. From a biomechanical standpoint, fixed functional appliances are more recommended to treat Class II in dolichofacial patients, in comparison to Class II elastics.

Considering the large number of fixed functional appliances, choosing the best device for your patient is not an easy task. To describe the development of fixed functional appliances as well as our 20-year experience working with them. Fixed functional appliances are grouped into flexible, rigid and hybrid. They are different appliances, whose action is described here. Four clinical cases will be reported with a view in illustrating the different appliances. Rigid fixed functional appliances provide better skeletal results than flexible and hybrid ones. Flexible and hybrid appliances have similar effects to those produced by class II elastics. They ultimately correct class II with dentoalveolar changes. From a biomechanical standpoint, fixed functional appliances are more recommended to treat class II in dolichofacial patients, in comparison to class II elastics. The electromyographic (EMG) activity of masticatory muscles was monitored longitudinally with chronically implanted EMG electrodes to determine whether functional appliances produce a change in postural EMG activity of the muscles. Pre-appliance and post-appliance EMG levels in four experiments that had been fitted with functional appliances were compared against the background of EMG levels in controls without appliances. The insertion of two types of functional appliance to induce mandibular protrusion was associated with a decrease in postural EMG activity of the superior and inferior heads of the lateral pterygoid, superficial masseter, and anterior digastric muscles; the decrease in the first three muscles was statistically significant. This decreased postural EMG activity persisted for approximately 6 weeks, with a gradual return towards pre-appliance levels during a subsequent 6-week period of observation. Progressive mandibular advancement of 1.5 to 2 mm every 10 to 15 days did not prevent the decrease in postural EMG activity.

The Forsus appliance is one of the most commonly used rigid fixed functional appliances in the correction of class II malocclusion. It is often seen that parts go missing with regular usage of the appliance. Replacement of the same is expensive and also requires a large inventory. An innovative low-cost and easy option for lost or broken split crimps is described in this article.

Mandibular Retrognathia

We are in the process of discovery of new vistas for technological advances in terms of various appliances with a vision of making orthodontic treatment compliance free as well as successful. Due to improved technology, the enigma of treating the Class II syndrome is palliated. “Out of the box” thinking has become a norm to treat certain situations that were not corrected in noncompliant patients. Fixed functional appliances are valuable tools introduced to assist the correction of skeletal Class II malocclusion with mandibular retrognathia at the deceleration stage of growth for achieving stable results. In this direction a case series is reported of patients having the above conditions and undergoing orthodontic treatment using a Forsus FFA. Joining hands with technology is a win-win situation for both the patient and the orthodontist.

Correction of skeletal Class II malocclusion has become a major challenge for orthodontists. Class II jaw discrepancies characterized by mandibular deficiency are treated with fixed functional appliances when there is no active growth present. This case report illustrates the application of PowerScope in 16 years young adolescent male having skeletal Class II Div 2 with mandibular deficiency who was reported with forwardly and irregularly placed upper front teeth with closed bite. The case was treated initially with MBT 0.022” prescription followed by PowerScope. Successful results were obtained with a substantial improvement in facial profile, skeletal jaw relationship and overall aesthetic appearance. PowerScope produced a significant forward movement of mandible which obliterated the need of extractions

The aim of this study was to evaluate the efficiency in using intermaxillary elastics to stimulate mandibular growth and advancement in orthodontic patients diagnosed with skeletal Class II malocclusion as well as to compare the use of these Class II elastics in two different therapeutic approaches. The sample consisted of 60 orthodontic patients aged 10-15 years, 34 girls and 26 boys. The sample was divided into two equal groups (each consisting of 30 patients). Patients belonging to the first group (Group 1) were subjected to 1/4�� - 6.0 oz elastics and were advised to change the elastic every 24 hours. Patients belonging to the second group (Group 2) were subjected to 1/4�- 4.5 oz elastics but with a recommendation to change the elastics every 12 hours. In order to evaluate the effectiveness of these two types of Class II elastics on mandibular growth and advancement, the value of the SNB angle at the beginning of the treatment (T1) was compared with the value of the SNB angle after 5 months of wearing intermaxillary elastics (T2). All patients showed statistically significant increased values of the SNB angle during the orthodontic treatment (p[0.001). Patients in Group 2 showed a significantly higher statistical increase (p[0.05) than patients in Group 1.
