Braces are meant for correcting crooked teeth; however, many people opt not to have archwires/metal wires being placed across their teeth. For this reason, braces behind teeth also called lingual braces, were developed to cater for this problem. Braces behind teeth make it hard to notice when an individual is undergoing through this type of dental treatment. The origin of braces behind teeth is traced back in 1970s when orthodontists in Japan and US worked separately in formulation of their own technique of lingual braces. The technology of lingual braces was first introduced in 1979 to American orthodontics offices, however, this type of braces failed to gain popularity during the first few years, until improved technology provided better maintenance and installation of braces behind teeth. best japan cams
What type of patient makes a good candidate for braces behind teeth?
Not every individual is capable of making a good candidate for these braces, normally, teenager’s adults and adults are recommended for this treatment option. Also the size of the teeth maters a lot as it is highly recommended for those patients having relatively normal sized teeth as opposed to small-sized teeth. The candidate should also have an accommodating bite relationship to the lingual braces presence, as existence of deep vertical overbite (excessive overlapping of teeth) or having an alignment that might exert heavy forces on the orthodontic brackets especially when chewing, are not recommended for braces behind teeth.
What is the technology associated with braces behind teeth? According to the research, the technology that lies behind this dental procedure is very complicated in that brackets and wires used with braces behind teeth are custom-fabricated for each patient using a robotic wire bending and Cam, Cad technology.
WHAT IS THE PROCESS ASSOCIATED WITH GETTING BRACES BEHIND TEETH?
The procedure for placing braces behind teeth involves three major steps i.e.
Taking impression of the tooth
Since the wires and brackets used here are custom made, the process comments by taking of very precise or exact impression of the patient`s teeth i.e. both lower and upper sides which are then sent, together with the dentist’s prescription on the desired final teeth alignment, to the dental or orthodontic laboratory responsible for making lingual braces hardware.
Fabrication of the lingual braces hardware by the dental laboratory
Here, the teeth plaster casts are made out of the teeth impression received from the dentist, then a set up for the patient`s case is created out of these plaster casts as per the orthodontist`s prescriptions. A setup is simply a mockup of the teeth usually arranged in a precise/perfect manner. After the completion of the setup, the next step involves scanning it into a computer to obtain a digitalized information which is then used in designing and creating (cam or cad technology) the customized series of archwires and orthodontic brackets needed for the procedure (robotic wire bending technology). When fabrication is completed, embedding of the orthodontics brackets into a tray called an applicator tray is done. Normally an applicator tray fits over the teeth and helps in holding the brackets in actual alignment during the technique used to fix them. When all this is complete, the orthodontic hardware is then sent back to the dentist`s office.
Attaching braces behind teeth
Normally, an appointment is made where the patient returns to the orthodontist`s office for the attachment of lingual braces which usually occurs about 4 weeks after the impressions were first obtained. In this step, braces behind teeth are attached by application of cement at the back of every bracket and then the applicator tray is pressed in order to hold these brackets into position over the teeth (meaning that all brackets contained in one arch are bonded or cemented into position at the same time). The applicator tray makes sure that each bracket stays in precise alignment when its cement sets. After the setting up of the cement, the applicator tray is broken away by the dentist hence making the brackets to remain in position on the patient`s teeth. Trimming and smoothening of any excess cement is carried out. The last step involves installation of the pre-bend archwires prepared by the dental laboratory right after securing of the brackets after which the braces behind teeth are considered in place and the patient is termed as undergoing active treatment.
