Damon System New way System for orthodontics

The Damon system

The Damon system of orthodontics is one among four fastened, passive, self-ligating strategies of correcting malocclusions—the different 3 being the sensible clip, the Praxis Glide, and also the Carriere LX. Passive self-ligating systems use brackets that don't need elastic o-rings to carry the wires in place. By not using the elastic o-rings, the wires freely slide through the slots while not friction, that necessitates new mechanics to use the system to maneuver teeth. additionally, no o-rings suggests that higher oral hygiene, since they're a major entice for oral bacteria. to carry the wires in place, the Damon System uses little sliding doors. The addition of 'stops' on the wires helps stop the wire from turning into displaced from its meant location.

How braces work

ortho tools
The application of braces moves the teeth as a results of force and pressure on the teeth. There are four basic parts that are required so as to assist move the teeth. within the case of ancient metal or wire braces, one uses brackets, bonding material, arch wire, and ligature elastic, conjointly known as an “O-ring”[2] to assist align the teeth. The teeth move when the arch wire puts pressure on the brackets and teeth. generally springs or rubber bands are used to place additional force during a specific direction. Braces have constant pressure, that over time, move teeth into their correct positions. often adults may have to wear headgear to stay bound teeth from moving. When braces place pressure on ones teeth, the periodontal membrane stretches on one facet and is compressed on the opposite. This movement has to be done slowly otherwise the patient risks losing his or her teeth. this is often why braces are commonly worn for roughly 2 and a [*fr1] years and changes are solely created each 3 or four weeks.

History of orthodontic braces

Ancient Times
“Father of Orthodontics”


Braces date all the manner back to earlier period in keeping with several students and historians, and existed round the time 2022–2030 BC. several consultants say that around 400-500BC, Hippocrates and Aristotle contemplated concerning ways in which to straighten teeth and to mend varied dental conditions. Archaeologists have come back to find varied mummified ancient people with the looks of metal bands wrapped around their teeth. it's been perceived that catgut, that could be a form of twine that's made of the natural fibers of an animal’s intestines, did the work that's done by today’s orthodontic wire used to shut gaps within the teeth and mouth.[1] Meanwhile in Greece, the Etruscans, seen because the early Romans, were burying their dead with dental appliances in place that were used to take care of house and forestall collapse of the teeth throughout when life. though there's no date documented, this method was presumably before the beginning of our era. An unknown researcher found a Roman tomb with variety of teeth sure with gold wire documented as a ligature wire, that could be a tiny elastic wire that's used to affix the arch wire to the bracket. within the early years of our era, a thinker and physician, Aurelius Cornelius Celsus, 1st recorded the treatment of teeth by finger pressure.[1] sadly, as a result of lack of proof, the poor preservation of bodies, and primitive technology, not abundant analysis was done on dental braces till round the seventeenth century, though dentistry as a profession was creating nice advancements.
