Molar distalization is a process in the field of Orthodontics which is used to move molar teeth, especially permanent first molars, distally (backwards) in an arch. This procedure is often used in treatment of patients who have Class 2 malocclusion . [ 1 ]
Intrusion is done in orthodontics to correct an anterior deep bite or in some cases intrusion of the over-erupted posterior teeth with no opposing tooth. [1] Intrusion can be done in many ways and consists of many different types. Intrusion, in orthodontic history, was initially defined as problematic in early 1900s and was known to cause ...
Man-Suk Baek and others evaluated long-term stability of anterior open bite by intrusion of maxillary posterior teeth. Their results showed that the molars were intruded by 2.39 mm during treatment and relapsed back by 0.45 mm or 22.8%. The incisal overbite increased by 5.56 mm during treatment and relapsed back by 1.20 mm or 17%.
It is a general rule to expand the maxilla to a point where the lingual cusp of maxillary molar teeth touch the buccal cusp of mandibular molar teeth. Studies done decades ago by Krebs [ 14 ] (1964), Stockfisch [ 15 ] (1969) and Linder Aronson [ 16 ] (1979) showed that about one-third to one-half of the expansion was lost before the expansion ...
An oroantral fistula (OAF) is an epithelialized oroantral communication (OAC), which refers to an abnormal connection between the oral cavity and the antrum. [1] The creation of an OAC is most commonly due to the extraction of a maxillary tooth (typically a maxillary first molar) which is closely related to the antral floor.
In 1909, Charles A. Clark described a radiographic procedure for localizing impacted teeth to determining their relative antero-posterior position. [1] If the two teeth (or, by extension, any two objects, such as a tooth and a foreign object) are located in front of one another relative to the x-ray beam, they will appear superimposed on one another on a dental radiograph, but it will be ...
Kole in 1959 was the first person to speak about the procedure of corticotomy in adults with maxillary constriction. [1] Brown first described the surgical technique for SARPE in 1938. [ 2 ] Steinhauser [ 3 ] first described the technique involving the segmental left/right split of maxilla along with placement of the graft in 1972.
The creation of this interocclusal space will significantly reduce the amount of tooth preparation required, especially on the already compromised palatal surfaces of the maxillary anterior teeth. Adaptation occurs over a period of some months: compensatory eruption of the posterior teeth will occur, together with some intrusion of the anterior ...
