  2. Theories of craniofacial growth - Wikipedia

    en.wikipedia.org/.../Theories_of_Craniofacial_Growth

    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 ...

    en.wikipedia.org/wiki/Posselt's_Envelope_of_Motion

    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.

  4. Little's Irregularity Index - Wikipedia

    en.wikipedia.org/wiki/Little's_Irregularity_Index

    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.

  5. Cephalometric analysis - Wikipedia

    en.wikipedia.org/wiki/Cephalometric_analysis

    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. [5]

  6. Intrusion (orthodontics) - Wikipedia

    en.wikipedia.org/wiki/Intrusion_(orthodontics)

    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.

  7. Orthodontic indices - Wikipedia

    en.wikipedia.org/wiki/Orthodontic_indices

    2 types of malalignment are being measured, rotation and displacement. Rotation is defined as the angle formed by the line projected through contact areas of observed tooth and the ideal arch line. Displacement is defined as both of the contact areas of the tooth are displaced in the same direction from the ideal alignment position. [8]

  8. Orthognathic surgery - Wikipedia

    en.wikipedia.org/wiki/Orthognathic_surgery

    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 ...

  9. Orthodontic technology - Wikipedia

    en.wikipedia.org/wiki/Orthodontic_technology

    Orthodontic headgear is a type of appliance attached to dental braces that aids in correcting more severe bite problems. Headgear is an orthodontic appliance for the correction of Class II correction, typically used in growing patients to correct overbites by holding back the growth of the upper jaw, allowing the lower jaw to catch up.
