WELCOME TO THE WEBSITE OF OUR DENTAL LABORATORY OF ORTHODONTICS AND REMOVABLE PROSTHESIS
Bionator is one of the most demanded functional appliances in an orthodontic laboratory. It is possible that the fundamental cause of this fact is the simplicity of its structure and the comfort of its use for the patient. It was designed by Balters in 1960, who attributed to the language a causal role of the first order in the cause of malocclusions.
The bionator is actually much less bulky than the activator. The part that covers the anterior section of the palate, which is contiguous with the tongue, is missing. For this reason children can speak normally as soon as they start to use it, even if the device is loose in the mouth, this makes it possible to use the device day and night, except during meals. An important aspect of the bionator is its freedom of movement in the oral cavity.
Uses of the Bionator Functional Apparatus
The bionator is a device developed to align the arch, its main objective is to correct a skeletal class II malocclusion and turn it into a class I molar relationship, increasing the vertical dimension, bringing the jaw down and forward, correcting the overbite and relieving a possible compression of the TMJ.
You can expand moderately narrow arches and correct protruding upper incisors by rotating the premaxilla downward and distally, thus correcting excessive protrusion problems.
It is also used to buccalize lower anterior teeth that have been lingualized in the lower arches. In the vestibular area, it serves to eliminate the subvestibular sulcus and release the retruded lower lip and the tension of the orbicularis oculi muscle. It helps the patient obtain a correct lip seal and correct incorrect upper and lower lip relationships.
It is also capable of eliminating serious periodontal and mucous damage on the palate and gingiva caused by excessive deep overbite problems. By correcting severe mandibular retruction, it also corrects the malposition of the tongue and consequently the resulting atypical swallowing pattern. Acting as a display device, it also prevents the tongue from imposing on the occlusal surfaces of the posterior teeth, thus achieving correction of vertical problems and helping to achieve the correct occlusal plane.
These appliances bring the tongue back to its correct position against the soft palate, eliminate lingual suction during swallowing, and help keep the tongue in more correct and proper function. They also work very successfully in eliminating the sucking habit in children who complicate their malocclusion by habitually sucking various combinations of fingers and thumbs.
In the catalog of our orthodontic laboratory you can find the Bionator and we are at your disposal to attend to the different variants that this functional appliance may present.
