Orthodontic Braces
Dental braces (also known as braces, orthodontic cases, or cases) are devices used in orthodontics that align and straighten teeth and help position them with regard to a person's bite, while also aiming to improve dental health. They are often used to correct underbites, as well as malocclusions, overbites, open bites, gaps, deep bites, cross bites, crooked teeth, and various other flaws of the teeth and jaw. Braces can be either cosmetic or structural. Dental braces are often used in conjunction with other orthodontic appliances to help widen the palate or jaws and to otherwise assist in shaping the teeth and jaws. Process The application of braces moves the teeth as a result of force and pressure on the teeth. There are traditionally four basic elements used: brackets, bonding material, arch wire, and ligature elastic (also called an “O-ring”). The teeth move when the arch wire puts pressure on the brackets and teeth. Sometimes springs or rubber bands are used to put ...

X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz ( to ) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiberotomy
A fiberotomy or pericision is an orthodontic surgical procedure designed to sever the gingival fibers around a tooth. It usually reduces the tendency to relapse of tooth rotations corrected by dental braces or other treatments. The most frequently encountered post-orthodontic problem is the retention of re-established tooth position. Relapse (drifting of the tooth back to its position prior to orthodontic correction) may occur anywhere, but it is often associated with teeth that have undergone rotation (twisting) as part of the orthodontic therapy. fiberotomyinvolves the detachment of the fibers that attach the tooth to the bone via the gum. The fibers act much like twisted rubber bands and releasing the tension between the fibers and the tooth reduces the forces that attempt to pull the tooth back to its original position. It is performed near the completion of the orthodontics and is shown to be effective in preventing the relapse of teeth. To perform this procedure, there is the ...

Orthodontic Headgear
Orthodontic headgear is a type of orthodontic appliance typically attached to the patient's head with a strap or number of straps around the patient’s head or neck. From this, a force is transferred to the mouth/jaw(s) of the subject. Headgear is used to correct bite and support proper jaw alignment and growth. It is typically recommended for children whose jaw bones are still growing. Unlike braces, headgear is worn partially outside of the mouth. An orthodontist may recommend headgear for a patient if their bite is more severely out of alignment. The device typically transfers the force to the teeth via a facebow or J hooks to the patient's dental braces or a palatal expander that aids in correcting more severe bite problems or is used in retention of the teeth and jaws of the patient. Need for treatment and concurrent corrections Headgear is most commonly used to correction anteroposterior discrepancies. The headgear attaches to the braces via metal hooks or a facebow. S ...

Dental Arch
The dental arches are the two arches (crescent arrangements) of teeth, one on each jaw, that together constitute the dentition. In humans and many other species; the superior (maxillary or upper) dental arch is a little larger than the inferior (mandibular or lower) arch, so that in the normal condition the teeth in the maxilla (upper jaw) slightly overlap those of the mandible (lower jaw) both in front and at the sides. The way that the jaws, and thus the dental arches, approach each other when the mouth closes, which is called the occlusion, determines the occlusal relationship of opposing teeth, and it is subject to malocclusion (such as crossbite) if facial or dental development was imperfect. Because the upper central incisors are wider than the lower ones, the other teeth in the upper arch are arrayed somewhat distally, and the two sets do not quite correspond to each other when the mouth is closed: thus the upper canine tooth rests partly on the lower canine and p ...

Palatal Expander
A palatal expander is a device in the field of orthodontics which is used to widen the upper jaw (maxilla) so that the bottom and upper teeth will fit together better. This is a common orthodontic procedure. Although the use of an expander is most common in children and adolescents 8-18 years of age, it can also be used in adults, although expansion is slightly more uncomfortable and takes longer. A patient who would rather not wait several months for the end result by a palatal expander may be able to opt for a surgical separation of the maxilla. Use of a palatal expander is most often followed by braces to then straighten the teeth. It is believed that expansion therapy should be started in patients either before or during their peak growth spurt. To obtain maximal skeletal changes, the therapy is typically initiated at a very early age. Expansion therapy performed after the peak growth spurt will lead to more dental changes than skeletal which leads to tipping of buccal teeth ...

Ligature (orthodontic)
Elastics are rubber bands frequently used in the field of orthodontics to correct different types of malocclusions. The elastic wear is prescribed by an orthodontist or a dentist in an orthodontic treatment. The longevity of the elastic wear may vary from two weeks to several months. The elastic wear can be worn from 12 to 23 hours a day, either during the night or throughout the day depending on the requirements for each malocclusion. The many different types of elastics may produce different forces on teeth. Therefore, using elastics with specific forces is critical in achieving a good orthodontic occlusion. The term ''intermaxillary elastics'' is used when elastics can go from the maxillary to the mandibular arch. ''Intra-maxillary elastics'' are elastics used in one arch only, either mandibular or maxillary. People using elastics for orthodontic correction change their elastics three to four times during the day. Elastic wear is recommend to be used in a rectangular wire to min ...

Archwire
An archwire in orthodontics is a wire conforming to the alveolar or dental arch that can be used with dental braces as a source of force in correcting irregularities in the position of the teeth. An archwire can also be used to maintain existing dental positions; in this case it has a retentive purpose. Orthodontic archwires may be fabricated from several alloys, most commonly stainless steel, nickel-titanium alloy (NiTi), and beta-titanium alloy (composed primarily of titanium and molybdenum). Types Noble Metal alloy Noble metals such as gold, platinum, iridium, silver and their alloys were used early on in the field of Orthodontics because of their good corrosion resistance. Some of the other qualities that these alloys had were high ductility, variable stiffness (with heat), high resilience and ease of soldering. Disadvantages of these alloys were: Less elasticity, less tensile strength and greater cost. Composition of both platinum and palladium raised the melting po ...

Dental Fillings
Dental restoration, dental fillings, or simply fillings are treatments used to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as to the replacement of such structure supported by dental implants. They are of two broad types—''direct'' and ''indirect''—and are further classified by location and size. A root canal filling, for example, is a restorative technique used to fill the space where the dental pulp normally resides. Tooth preparation Restoring a tooth to good form and function requires two steps: # preparing the tooth for placement of restorative material or materials, and # placement of these materials. The process of preparation usually involves cutting the tooth with a rotary dental handpiece and dental burrs, a dental laser, or though air abrasion to make space for the planned restorative materials and to remove any dental decay or portions of the tooth that are structurally unsound. ...
