In fixed retainers, composite is usually placed to bond and to cover the wire, whilst ensuring no interference in the interdental space. Fixed retainers are used in situations where instability is more likely, such as severe rotations, periodontal disease and median diastemas. Occasionally the patient will require a removable retainer as well.
It is important to note that initially dento-facial Orthopaedics was mainly done in Europe. The United States was introduced to Fixed Orthodontics by Edward Angle. Norman William Kingsley was the first person to show "jumping the bite" by using an anterior bite plate. Hotz then developed the Vorbissplate which was a modification of Kingsley's ...
A Hawley retainer is also a removable orthodontic appliance made from a combination of plastic and metal that is custom-molded to fit the patient's mouth. Removable retainers will be worn for different periods of time, depending on the patient's need to stabilize the dentition.
In the United States a smart retainer sensor is exclusively provided by orthodontists who have signed up to be providers, and should retail for around $100. The SMART Retainer was featured on the May 15 episode of The Today Show. [1] Here is an abstract of an article in the American Journal of Orthodontics and Dentofacial Orthopedics:
Retainers help in maintaining and stabilizing the position of teeth long enough to permit the reorganization of the supporting structures after the active phase of orthodontic therapy. If the patient does not wear the retainer appropriately and/or for the right amount of time, the teeth may move towards their previous position.
They involve attaching the orthodontic brackets on the inner (lingual vs. buccal) sides of the teeth. The main advantage of lingual braces is their near invisibility [ 1 ] compared to the standard braces, which are attached on the buccal (cheek) sides of the tooth . [ 2 ]
Common applications for this technology in dentistry include but are not limited to modeling, temporary prosthetics, retainers, aligners, and orthodontic models. An ultraviolet (UV) laser is used to cure a liquid polymer resin into layers. This liquid polymer is then held in a container as the laser polymerizes the layers of resin.
