Wire slot Bracket base - can be used to spot weld onto orthodontic bands Tie wings Orientation marker - placed on disto-gingival aspect of tooth Brackets can be made from stainless steel or porcelain. Brackets can be luted onto teeth using either a direct or indirect technique. Direct techniques involve conventional acid etch and chemical or light cured composites. The indirect technique involves the appliance's brackets being light cured to a working orthodontic model to allow a thin soft splint blow down appliance to be constructed over the model to aid placement of the brackets onto the teeth.
Orthodontic Bands Used most frequently on either molar or occasionally premolar teeth. They are the means through which a force is applied to the tooth.

They are made from stainless steel and have one or more tubes running through them. The large round tube is for a facebow and the smaller square tube is for the archwire. They can also have a number of pre-adjusted features built into their design, which will influence the position of teeth. Archwires Archwires are made from differing metal alloys, and are supplied as either straight lengths or as pre-formed archwires. There are different types of archwires including: Ligating is done using either elastic modules or thin wire ligatures: The closer the fit of the arch wires in the slot on the bracket, the greater the control of the teeth.
As treatment progresses, thicker wires are used to fully control the teeth in three dimensions. Auxiliaries Coils or springs - used to generate space by opening up a space by pushing teeth apart or to close space.
Elastics - active components which come in the form of bands, threads or chain Long ligatures - used to tie several teeth together to generate anchorage Crimpable hooks - can have elastics or closing coils attached to them.
Functional appliances[ edit ] When there is a maxillary overjet, or Class II occlusion, functional appliances can be used to correct the occlusion, it is recommended that the professional be a specialist in orofacial orthopedics to perform this typy ofand personal preference.
The most common fixed appliance being used today is the Pre-adusted Edgewise Appliance. In Viggo Andresen applied his bracket for the first time. Andresen used the activator to stimulate the development of the lower jaw and the lower teeth in growing children orthodontically.
These may be fixed or removable. Other classes of functional appliances include removable appliances and over the head appliances, and these functional appliances are used to redirect jaw growth. Dental bracesremoved after completion of treatment.
During fixed orthodontic treatment, metal wires are held in place by elastic bands on orthodontic brackets braces on each tooth and inserted into bands around the molars. The orthodontic archwires can be made from stainless steel, nickel-titanium Ni-Ti  or a more aesthetic ceramic material.

Ni-Ti is used as the initial arch wire as it has good flexibility, allowing it to exert the same forces regardless of how much it has been deflected. There is also heat activated Ni-Ti wire which tightens when it is heated to body temperature. Fixed orthodontic appliances aid tooth movement, and are used when a 3-D movement of the tooth is required in the mouth and multiple tooth movement is necessary.
Ceramic fixed appliances can be used which more closely mimic the tooth colour than the metal brackets. Some manufacturers offer self-litigating fixed appliances where the metal wires are held by an integral clip on the bracket themselves.
These can be supplied as either metal or ceramic. Currently there is not enough evidence to determine whether self-etch preparations or conventional etchants cause less decalcification around the bonding site and if there is a difference between them in bond failure rate.
This is similar to composite filling material.
Examples of functional appliances are: This treatment comes in three stages. Prior to surgery there is orthodontic treatment to align teeth into their post-surgery occlusion positions.
The bone is broken during surgery and is stabilised with titanium plates and screws, or bioresorbable plates to allow for healing to take place. They are normally flat, chisel-shaped teeth that meet in an edge-to-edge bite. Their function is cutting, slicing, or gnawing food into manageable pieces that fit into the mouth for further chewing.
The canines are immediately behind the incisors. In many mammals, the canines are pointed, tusk-shaped teeth, projecting beyond the level of the other teeth.
In carnivores, they are primarily offensive weapons for bringing down prey. In other mammals such as some primates, they are used to split open hard surfaced food.
The premolars and molars are at the back of the mouth. Depending on the particular mammal and its diet, these two kinds of teeth prepare pieces of food to be swallowed by grinding, shearing, or crushing. The specialised teeth—incisors, canines, premolars, and molars—are found in the same order in every mammal.
These are called deciduous teethprimary teeth, baby teeth or milk teeth. Normally the dental formula for milk teeth is the same as for adult teeth except that the molars are missing.
