Study Notes

Orthodontics Terminology

  • The term "orthodontics" is derived from the Greek words "orthos" meaning straight and "odont" meaning tooth.

Definition of Orthodontics

  • According to the American Board of Orthodontics, the main responsibility of orthodontics is to diagnose, prevent, and treat dentofacial irregularities.
  • Noyes defined orthodontics in 1911 as "the branch of dental science which deals with the prevention and correction of irregularities of the teeth".
  • Angle stated that the objective of the science of orthodontics is to harmonize the development of the teeth and jaws.

Aims and Objectives of Orthodontic Treatment

  • According to Jackson's Triad, one of the aims and objectives of orthodontic treatment is to achieve a satisfactory occlusion.

Malocclusion Characteristics

  • A characteristic of an open bite malocclusion is a space between the upper and lower teeth when the mouth is closed.
  • A skeletal open bite malocclusion is caused by a lack of closure of the bite due to an underlying skeletal problem.
  • Malocclusions associated with decreased vertical facial dimensions are classified as deepbites.
  • In a Type 2 deepbite, the mandibular incisors impinge on the mucosa palatal to the maxillary incisors.
  • A dental open bite malocclusion is caused by a habit, such as thumb-sucking, or a muscle imbalance that causes the teeth to move apart.
