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 early 1980s, American orthopedist Harold Frost published a review article detailing then known experiences with regional acceleratory phenomena, which can be caused by injuries such as fractures and burns, afflictions such as acute paralysis and arthritis, bone movement such as implant placement and orthodontics, as well as vitamin D, thyroxine, and electrical stimuli.
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.
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.

Open bite is a type of orthodontic malocclusion which has been estimated to occur in 0.6% of the people in the United States. This type of malocclusion has no vertical overlap or contact between the anterior incisors. [1] The term "open bite" was coined by Carevelli in 1842 as a distinct classification of malocclusion.
Orthodontic indices are one of the tools that are available for orthodontists to grade and assess malocclusion. [1] Orthodontic indices can be useful for an epidemiologist to analyse prevalence and severity of malocclusion in any population.
Bolton Analysis is a tooth analysis developed by Wayne A. Bolton to determine the discrepancy between size of maxillary and mandibular teeth. This analysis helps to determine the optimum interarch relationship.
In an earlier study published in 2008, [6] the same authors stated that about one-third of the transverse dental expansion obtained with SARPE is lost, however the skeletal expansion remains the same. They also stated that post-surgical relapse with SARPE was similar to the changes in dental arch dimensions after non-surgical rapid palatal ...
