Malunited or Non-Healing Jaw Fractures: Diagnosis & Corrective Surgery
A clear guide to malunited or non-healing jaw fractures, when a previous jaw fracture heals in the wrong position or fails to heal, and how it is corrected.
Treatment usually begins with
Bite & Function Assessment
Imaging
Specialist Consultation
Corrective Surgery
Treatment involves surgically correcting the healed position or re-establishing healing, restoring normal bite and jaw function.
You may need this evaluated if...
Evaluation is recommended for a previous jaw fracture when:
- A bite that doesn't feel right after a jaw fracture has healed
- Ongoing pain or instability at a previous fracture site
- Visible facial asymmetry following a healed jaw fracture
- A fracture site that hasn't shown expected healing on follow-up imaging
Even a fracture that has healed incorrectly or failed to heal can usually be successfully corrected with appropriate surgical treatment.
What is Malunited or Non-Healing Jaw Fractures?
A malunited jaw fracture heals in an incorrect position, while a non-union fails to heal at all, both requiring specialist evaluation and corrective surgery to restore normal bite, function and facial appearance.
Two Related but Distinct Problems
Malunion means healing in the wrong position, while non-union means the bone hasn't healed at all.
Function Guides Treatment Urgency
A bite that doesn't work well or ongoing instability are key indicators for correction.
Correction Is Achievable
Corrective surgery can restore proper alignment and function even months after the original injury.
Careful Planning Improves Outcomes
Detailed imaging and planning are used to achieve the best possible correction.
Common Symptoms
- A bite that feels misaligned after a healed jaw fracture
- Ongoing pain or a feeling of instability at the old fracture site
- Visible facial asymmetry
- Difficulty chewing normally
What Increases Your Risk
A combination of dental, developmental and lifestyle factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
Clinical Bite & Function Assessment
Evaluates how the jaw currently functions and where problems exist.
CT Imaging
Shows the exact position of the healed or unhealed fracture.
Comparison With Original Injury Records
Where available, helps understand how the healing pattern developed.
Nerve Function Testing
Assesses whether any nerve involvement needs to be addressed alongside bone correction.
Treatment Approaches
Conservative Management
- Physical therapy for jaw function if surgery is not immediately needed
- Pain management for ongoing discomfort
- Dietary modification while awaiting definitive treatment
- Orthodontic support in select cases involving bite adjustment
Surgical Treatment
Corrective surgery re-breaks and realigns a malunited fracture, or stabilizes and grafts a non-union, to restore normal bite and jaw function.
Treatment decisions are based on imaging, the extent of involvement and your overall dental and facial anatomy, not a single standard approach.
Know When to Act
Recognising these signs early and acting promptly helps protect your jaw function and facial health.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing concern.
- A bite that feels slightly off after a previous jaw fracture, seeking evaluation
Seek Urgent Care
Reach out for emergency care immediately if you notice any of the following.
- Sudden worsening pain, instability or new swelling at a previous fracture site
