  • Introduction:   Vertical malocclusion results from interplay of many etiological factors during growth period. These growth factors include growth of maxilla and mandible, variations in rate of growth in both the maxillary suture and mandibular condyles and dentoalveolar development with the eruption of the teeth. The potential etiological factors other than unfavorable growth patterns are, digit sucking habits, lymphatic tissue, tongue and orofacial muscle activity, heredity, orofacial functional matrices, jaw posture, head position.
  • The correction of vertical dysplasia are more difficult and more challenging  than the correction of anterior- posterior, transverse malocclusions, hence the need for proper diagnosis and treatment plan
  • MYOTHERAPY
  • According to Profitt  myofunctional therapy is defined as any therapeutic approach that involves muscle exercises with appliance or not. He consider myofunctional therapy as an adjunct to orthodontic appliance therapy in patient’s age 10 or older i.e. late mixed dentition or early permanent dentition with a treatment objective to alter resting tongue and lip posture. This approach takes advantage of function to adapt to form. Myofunctional therapy is not preventive measure.
  • Also A.P.Roger in 1906 suggested that muscle exercise be used as an adjunct tomechanical correction of malocclusion.
  • The principal purpose of myotherapy is creation of normal orofacial muscular function to aid growth and development of normal occlusion.
