Discuss the contributing roles of Andresen and Kingsley in the origin and development of the functional appliances Viggo Andresen Designed an inert appliance that fitted loosely in the mouth and by its mobility transferred muscular stimuli to the jaws, teeth and supporting structures. This appliance was initially a Hawley appliance. The Hawley appliance teamed up with HAUPL, and it was called the Activator because of its ability to activate muscles. So Andresen designed the first appliance to transfer functioning stimuli to the jaws, teeth and supporting tissues.Norman KingsleyHistorians claim that two different men deserve the title of being called "The Father of Orthodontics." One man was Norman W. Kingsley, a dentist, writer, artist, and sculptor, who wrote his "Treatise on Oral Deformities" in 1880. What Kingsley wrote influenced the new dental science greatly. The history of the functional appliance can be traced back to 1879, when Norman Kingsley introduced the "bite-jumping" appliance. The earliest evidence of functional orthodontics was an appliance designed by Kingsley, this dentally anchored appliance was meant to maintain the mandible in a forward position. A Kingsley appliance is considered a prototype functional appliance due to its continuous labial bow and bite planes extending posteriorly. Kingsley is known as the “father” of functional appliances.
Kingsley used the idea that a bending of the alveolar bone would take place during orthodontic tooth movement when he described his vulcanite maxillary appliance that positioned the mandible anteriorly and guided dental eruption in an attempt to “jump the bite” as he termed it.
ReplyDeleteKingsley described the plate that he had designed in the following way – “It was adapted to the inside of the superior dental arch and the inclined surface projected below and caught the inferior incisors”. The object was not to protrude the lower teeth but to change or jump the bite in the cases of an excessively retreating lower jaw.
