This method was proposed by Dr. Burstone in 1950s. This segmental arch method used two posterior segments and one anterior segment. [4] A separate continuous intrusion arch is used which was inserted in the auxiliary tube of molars on one end and tied to the anterior segment on the other end.
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%.
A lingual arch is an orthodontic device which connects two molars in the upper or lower dental arch. The lower lingual arch (LLA) has an archwire adapted to the lingual side of the lower teeth. In the upper arch the archwire is usually connecting the two molars passing through the palatal vault, and is commonly referred as "Transpalatal Arch ...
These appliances can be used to achieve expansion in the maxillary arch; there are devices for mandibular expansion or lower expansion too. In past many years, different types of appliances have been made. These types are: tissue-borne, tooth-borne, slow maxillary expansion, rapid maxillary expansion, and bone-anchored.
Class 2 elastics are used from the lower first molar to the upper canine tooth. [1] They can be used for many different reasons, such as Class 2 malocclusions, to reinforce anchorage in a case where an extraction has been done, to allow the maxillary incisors to move backwards, and to correct midline deviation and allow buccal movement of ...
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 ]
They also stated that the eruption of maxillary second molars had minimal effect on distalization of first molars. In addition, the reported increase of Lower Anterior Facial Height for patient's who had pre-existing vertical growth. They concluded that the pendulum appliance was an effective and reliable method for distalizing maxillary molars.
In the maxillary arch nerves for infiltration are branches of the superior alveolar, the greater palatine and the nasopalatine nerve Posterior superior alveolar nerve supplies the molars (not including the mesiobuccal root of the maxillary first molar), the surrounding bone, periodontal ligament, periosteum and buccal soft tissues
