Purpose: Fixed aid for the correction of Class II malocclusions
Increased bite position correction
After exceeding the growth maximum, frequently occurring Class II malocclusions characterised by mandibular retrusion can only be treated with fixed appliances. Also with children and adolescents more and more fixed appliances are now used to realise the treatment independently from the compliance of the patient.
Elastic, bimaxillary fixed appliances are disadvantageous as they only achieve predominantly dentoalveolar correction while rigid appliances have been proven to correct the skeletal bite more extensively. This mainly relies on stimulation of the adaptive osseous remodelling process in the temporomandibular joint, which has already been explained in numerous studies. The rigid Functional Mandibular Advancer (according to Prof. Dr. Gero Kinzinger and Dr. Jens Ostheimer) is a therapeutic alternative to existing appliances. Its main elements are protrusive bars and inclined planes which are fixed bilaterally to the vestibular in the buccal corridors on thermoforming splints or welded bands.
