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 ...
In the temporomandibular joint, the initial mouth opening occur by rotation, within the inferior cavity of the joint. [14] The TMJ rotates around a fixed axis within the condyle, with no antero-inferior translation. [14] The maximum jaw opening with this rotation movement is indicated as 'R' on the Posselt's envelope of motion.
A growth center is located in the head of each mandibular condyle before an individual reaches maturity. This growth center consists of hyaline cartilage underneath the periosteum on the articulating surface of the condyle. This is the last growth center of bone in the body and is multidirectional in its growth capacity, unlike a typical long bone.
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.

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 ]
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.
In orthodontics, a malocclusion is a misalignment or incorrect relation between the teeth of the upper and lower dental arches when they approach each other as the jaws close. The English-language term dates from 1864; [1] Edward Angle (1855–1930), the "father of modern orthodontics", [2] [3] [need quotation to verify] popularised it.
