What is Interceptive Orthodontics?

TeethInterceptive orthodontics is defined as the existing interference elimination with the key factors which are involved in the dentition development. In this article, there is a brief discussion on the interceptive orthodontics. Let us examine them.

Definition:

Interceptive orthodontics

is defined as the phase of the art and science of orthodontics employed for recognizing and eliminating the potential irregularities and the malpositions of the developing dento-facial complexes.

Interceptive orthodontics is commonly undertaken at the time when the malocclusion is developing or has already developed. Thus, an interceptive orthodontics refers to the measures undertaken for preventing a potential malocclusion from the progression into a more severe one.

The procedures carried out in the preventive orthodontics, some of them can be carried out in the interceptive orthodontic treatment. But, the timings are different.

Procedures:

The procedures that are undertaken in the interceptive orthodontics include the following:

  • Serial extraction
  • Control of the abnormal habits
  • Correction of the developing cross bite
  • Space regaining
  • Interception of the skeletal malrelation
  • Muscle exercises
  • Removal of bony barrier or soft tissue to enable the tooth eruption.

Serial extraction:

In the serial extraction, they plan the extraction of a certain deciduous teeth and then specific permanent teeth in a sequence order and pre-determined pattern in order to guide the permanent teeth eruption in a more favorable position. This is when one recognizes and anticipates the potential irregularities of the dento-facial complex.

History:

In 1929 Kjellgren first used “serial extraction” term. Nance (USA) in 1940’s popularized this technique.

Rationale:

This is based on two basic principles:

  • Physiologic tooth movement:

    Removal of the teeth, that is the erupting teeth must be guided by the natural forces to the extraction spaces.

  • Arch length tooth material discrepancy:

    tooth material must be greater than the arch length. Hence the erupting tooth occludes normally.

Indications:

  • Arch length deficiency
  • Class I malocclusions shows harmony between muscular and skeletal systems
  • Patients with pleasing appearance and straight profile
  • Where growth isn’t enough for overcoming discrepancy between basal bone and tooth material

Contraindications:

  • Class III and II malocclusions with the skeletal abnormalities
  • Anodontia or Oligodontia
  • Spaced dentition
  • Deep bite and open bite
  • Midline diastema
  • Unerrupted malformed teeth, example, dilacerations
  • Class I malocclusion with a minimal space deficiency
  • Heavily filled or extensive caries in the first permanent molars
  • Mild disproportion between tooth material and arch length that could be treated using proximal stripping

The above article discusses briefly about the interceptive orthodontics. Interceptive orthodontics is an early intervention in the dentition development in order to eliminate the potential factors or to minimize the developing malocclusion interfering with the normal occlusion.
