The Bionator appliance is a type of functional orthodontic appliance used in dentistry to correct jaw and bite problems. It is named after its developer, German orthodontist Prof. Dr. Wilhelm Balters. The Bionator appliance is designed to guide the growth and development of the jaws and improve the alignment of the teeth. It works by influencing the growth and position of the jaws, stimulating their natural development. By placing the lower jaw in a more favorable position, it helps to correct issues such as overbite, underbite, and crossbite. It also encourages the harmonious growth of the facial bones and muscles. Though active plates and fixed appliances are important in obtaining proper arch form, the proper inter arch alignment is an important facet of functional appliances. And to date bionator towers.
