He defined Forward Rotation of jaw where the posterior growth of maxilla and mandible is greater than the anterior and Backward Rotation as where the anterior growth of jaws is greater than the posterior areas. Björk also developed seven structural signs that helped find the direction of the growth of the mandible, also known as Bjork Analysis ...
Growth sites are dependent on the growth centers for growth. Some examples include sutures of cranial vault, lateral cranial base and maxilla. Growth Centers is an area in the bone that controls the overall growth of the bone from its locations through different signaling mechanisms. Growth at these centers are genetically controlled. All ...
Cephalometric analysis depends on cephalometric radiography to study relationships between bony and soft tissue landmarks and can be used to diagnose facial growth abnormalities prior to treatment, in the middle of treatment to evaluate progress, or at the conclusion of treatment to ascertain that the goals of treatment have been met.

Little's Irregularity Index is an index used in the field of Orthodontics to measure the crowding of Mandibular anterior arch. The index was first proposed by Robert M. Little in 1975 in his paper The Irregularity Index: A quantitative score of mandibular anterior alignment.
This index was implemented in 1987 by the British Orthodontic Standard Working Party after 10 members of this party formulated this index over a series of 6 meetings [27] This index is a fast, simple and robust way of assessing the standard of orthodontic treatment that an individual orthodontist is achieving or trying to achieve rather than ...
Orthognathic surgery (/ ˌ ɔːr θ ə ɡ ˈ n æ θ ɪ k /), also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and lower face related to structure, growth, airway issues including sleep apnea, TMJ disorders, malocclusion problems primarily arising from skeletal disharmonies, and other orthodontic dental bite problems that cannot ...
Intrusion is a movement in the field of orthodontics where a tooth is moved partially into the bone. 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.
Robert Edison Moyers (November 12, 1919 – January 8, 1996) was an American orthodontist who was the founder of the Center of Human Growth and Development (CHGD) at University of Michigan and chair of its orthodontic program for 28 years. He made significant contributions towards orthodontics through the development of CHGD and ...
