is often another causative factor in the development of OMD’s. Many specialists agree that a restricted lingual frenum can result in dental, speech,and skeletal changes (jaw and palate formation).
Because of the specialization of orofacial myology MST works closely with a variety of healthcare professionals to address problems that may ensue. They include: pediatricians, otolaryngologists, allergists, dental specialists, maxial-facial surgeons, orthodontists, physical therapists, and chiropractors.
What causes an OMD?
While it is often difficult to pinpoint a single cause of OMD, it can often result from one or more of the following problems:
- Improper oral habits including thumb, digit or long-term pacifier sucking
- Restricted airway due to enlarged tonsils or adenoids; allergies; or chronic nasal obstruction
- Family heredity
- Structural or physiological abnormalities such as a short lingual frenum (tongue tie) or abnormally large tongue (macroglossia)
- Chronic open mouth posture Neurological or developmental abnormalities
Common effects of OMD postures
Anterior tongue posture
This is the most common type of tongue posture, often referred to as “tongue thrust.” The front lips don’t close and the child often has his mouth open with the tongue protruding from beyond the lips.
Bilateral anterior tongue posture
The only teeth that touch are the molars with the bite completely open on both sides including the anterior teeth.
Bilateral tongue posture
The anterior bite is closed; however, the posterior teeth may be open on both sides. This is the most difficult thrust to correct.
What age should therapy begin?
Age is a very important factor to consider in treating OMDs. Early identification and treatment in youngsters as young as 4 may assist in eliminating thumb or finger sucking habits, and assist with improved dental facial development, or eliminate a speech impairment associated with OMD. A child of 8 to 9 years of age is old enough to undergo complete training.
