Summary

Altering dental occlusion with a Mandibular Orthopedic Repositioning Appliance (MORA) can affect visual focusing. These visual changes gradually reverse after discontinuing the appliance.

Area of Science:

  • Ophthalmology
  • Dentistry
  • Biomechanics

Background:

  • Dental occlusion plays a role in head posture and jaw alignment.
  • Subtle changes in the stomatognathic system may influence visual perception.

Purpose of the Study:

  • To investigate the impact of dental occlusion on visual focusing.
  • To determine if mandibular orthopedic repositioning appliances affect visual acuity.

Main Methods:

  • Thirty subjects were divided into an experimental group (MORA users) and a control group.
  • Visual focusing tests were conducted using a Maddox rod and Berens prismatic bars at varying distances.

Main Results:

  • Alterations in dental occlusion induced fluctuations in visual focusing.

  • The effects were observed after a period of wearing the MORA.

    • Conclusions:

    • Dental occlusion is a factor that can influence visual focusing capabilities.
    • MORA use can lead to temporary changes in visual function, with gradual recovery upon removal.
