Jaw Deformity Treatment
Precision surgical care to restore alignment, comfort, and facial harmony.
Understanding Skeletal Jaw Imbalance and Facial Proportion
Jaw deformities occur when the upper jaw, lower jaw, or both develop in positions that do not align properly. Because the imbalance originates in bone structure rather than tooth position alone, jaw deformities can affect bite function, facial symmetry, speech, and long-term oral health. Identifying the specific type of jaw imbalance is the first step toward determining the most effective treatment.
Types of Jaw Deformities
Underbite (Class III)
An underbite occurs when the lower jaw extends forward beyond the upper jaw. This can create chewing difficulty, tooth wear, and a concave facial profile.
Overbite (Class II)
An overbite develops when the upper jaw or upper teeth project excessively forward relative to the lower jaw. This may lead to bite imbalance, jaw strain, and changes in lip support.
Open Bite
An open bite occurs when the upper and lower front teeth do not contact when the mouth closes. This affects chewing efficiency, speech sounds, and bite stability.
Facial Asymmetry
Facial asymmetry results when one side of the jaw develops differently from the other. This can shift the bite, alter facial balance, and affect jaw joint function.
Skeletal vs Dental Jaw Problems
Some bite issues originate from tooth position alone and can be corrected orthodontically. Others arise from jawbone position and require surgical correction. Distinguishing between dental and skeletal causes is essential for proper treatment planning.
How Jaw Deformities Affect Function
Jaw imbalance can impact:
Because the jaws guide tooth contact and facial support, skeletal discrepancies influence both function and appearance.
Causes of Jaw Deformity
Jaw deformities may develop due to:
Many deformities become more noticeable during adolescence as the jaws mature.
Jaw Deformity vs Orthodontic Misalignment
Orthodontics moves teeth within the jaws.
Jaw deformities involve the position of the jaws themselves.
When the skeletal relationship is incorrect, braces alone cannot fully correct the bite or facial balance. In these cases, orthognathic (jaw) surgery may be recommended.
Evaluation of Jaw Structure
Assessment may include:
This determines whether the imbalance is dental, skeletal, or combined.
Relationship to Jaw Surgery
Jaw deformities that involve skeletal imbalance are often treated with orthognathic surgery to reposition the jaws into proper alignment. Surgical correction restores both functional bite mechanics and facial proportion.
Why Choose an Oral and Maxillofacial Surgeon
Jaw deformities involve the facial skeletal structure, occlusal function, and joint function. Oral and maxillofacial surgeons provide:
Specialist evaluation ensures accurate diagnosis and treatment direction.
When to Seek Evaluation
You may benefit from a jaw assessment if you notice:
Early evaluation clarifies treatment options.
