Orthodontics
Orthodontists guide teeth into proper alignment using controlled mechanical forces. However, long-term stability depends on the surrounding muscular environment. Teeth do not exist in isolation—they are influenced by tongue posture, breathing patterns, and functional habits over time.
Orofacial Myofunctional Therapy (OMT) supports orthodontic outcomes by addressing the underlying muscle patterns that influence tooth position and arch development. By improving tongue posture, promoting nasal breathing, and establishing a balanced oral rest position, OMT helps reduce the forces that can contribute to relapse.
OMT is designed to complement orthodontic treatment—not replace it—by supporting the functional foundation that influences long-term stability.
​
OMT may support orthodontic outcomes by:
-
Reinforcing proper tongue posture to support arch form
-
Reducing tongue thrust and dysfunctional swallowing patterns
-
Promoting nasal breathing to support craniofacial development
-
Improving muscle balance that supports stable occlusion
-
Supporting retention and long-term stability following treatment
Consider referral when the following are observed:
​
1. Functional Signs
-
Tongue thrust or forward tongue posture
-
Open mouth posture or chronic mouth breathing
-
Low tongue resting position
-
Dysfunctional swallowing patterns
2. Structural or Developmental Indicators
-
Narrow maxillary arch or high palatal vault
-
Anterior open bite or relapse following treatment
-
Spacing or flaring associated with tongue pressure
-
Delayed or unstable orthodontic progress
3. Stability Concerns
-
History of orthodontic relapse
-
Difficulty maintaining alignment despite retention
-
Excessive muscular pressure on dentition
-
Parafunctional habits impacting tooth position
​
Without addressing functional patterns, orthodontic correction may be influenced by the same forces that contributed to the original malocclusion. OMT is intended to support your treatment outcomes and is not a replacement for diagnosis or treatment.

Clinical Research & Evidence
1. Prevention of Orthodontic Relapse
Long-term stability depends on functional balance. Research demonstrates that neuromuscular patterns influence tooth position over time, making retention dependent on proper tongue posture and oral function.
A study published in the American Journal of Orthodontics and Dentofacial Orthopedics found that relapse rates were reduced by up to 62% in patients who completed myofunctional therapy compared to orthodontic treatment alone.

2. Improving Occlusal Stability and Treatment Success
Balanced muscle function supports more predictable occlusal outcomes. When oral musculature is coordinated, teeth fit together more efficiently and remain stable.
Research involving orthodontic patients demonstrated improved PAR scores and higher patient satisfaction when myofunctional therapy was incorporated alongside treatment.
3. Correcting Mouth Breathing and Narrow Arches
Chronic mouth breathing is associated with altered craniofacial growth, narrow arches, and increased risk of malocclusion due to improper tongue posture.
Research consistently identifies mouth breathing as a contributing factor in malocclusion and abnormal growth patterns.
