What does it reconstruct?
The lower jaw bone, the jaw joint, or both.
The mandible is your lower jaw. The temporomandibular joints, or TMJs, connect it to your skull near each ear.
Craniofacial & Facial Reconstruction
Mandibular / TMJ Reconstruction
Mandibular and temporomandibular joint reconstruction rebuilds damaged lower jaw bone or jaw joints to support chewing, alignment, and facial structure.
Does TMJ pain mean I need reconstruction?
Usually not.
Many TMJ disorders improve with nonsurgical treatment. Reconstruction is generally considered for severe structural damage, missing tissue, or selected conditions that have not responded to other care.
Is this the same as jaw alignment surgery?
No, although treatment may overlap.
Orthognathic surgery repositions jaw bones to improve alignment. Reconstruction replaces or rebuilds damaged or missing bone or joint structures.
01 · Overview
Rebuilding the jaw, the joint, or both
The lower jaw supports your lower teeth and helps shape your face. Its joints allow opening and side-to-side movement. Problems with these structures can affect chewing, speech, mouth opening, and how your teeth meet. [1]
Reconstruction may be considered after a tumor is removed, a serious injury, loss of bone, or severe joint damage. Depending on the defect, rebuilding may involve bone and soft tissue from another part of the body, surgical hardware, a joint prosthesis, or a combination. [3]
Not all jaw pain comes from a damaged joint, and reconstruction does not treat every cause of pain. Your team should distinguish muscle-related symptoms, dental problems, bite misalignment, and joint disease before recommending an operation. [1]
- Structures treated
- Lower jaw bone and/or jaw joints
- Anesthesia
- Usually general anesthesia
- Care setting
- Hospital-based care; stay varies with the reconstruction
- Recovery
- Staged healing, rehabilitation, and longer-term follow-up
Who plans this treatment?
Planning may involve an oral and maxillofacial surgeon, reconstructive plastic surgeon, or head and neck surgeon, with dental, rehabilitation, and nutrition specialists as needed. The team depends on the cause and extent of your condition.
Will my teeth be restored at the same time?
Not necessarily. Rebuilding the jaw and replacing teeth are related but separate steps. Dental implants or other restorations may require additional healing and procedures, especially after radiation or extensive tissue loss.
02 · Concerns & Goals
What brings people to a consultation
Changes in your jaw can affect eating, speaking, comfort, and appearance. An evaluation helps identify which structures need treatment.
Difficulty chewing or opening
Restricted movement, joint damage, or missing jaw bone can make meals difficult. Your team will assess which limitations reconstruction might improve.
Pain and stiffness
Persistent symptoms deserve a careful diagnosis. Pain involving muscles or nerves may continue even after the jaw structure is repaired.
A changed bite
Teeth that no longer meet comfortably can affect eating and jaw position. Dental and skeletal planning help clarify what can be corrected.
Changes in facial support
Injury, disease, or previous surgery may change the jawline or facial balance. Restoring support may be part of the plan alongside function.
03 · Options
How the approaches differ
These approaches address different problems and are not interchangeable. Your surgeon may recommend one approach or combine several based on imaging, tissue health, and your goals.
Bone graft reconstruction
Rebuilds a selected bone defect using transplanted bone.
How it worksBone is placed into the defect and secured while it heals into the surrounding jaw.
May suitSome smaller defects with a healthy tissue bed and suitable blood supply.
Main tradeoffGrafts can fail to unite or lose volume. Taking your own bone creates another healing site.
Vascularized bone flap
Replaces a larger defect with living bone and its blood supply.
How it worksBone, sometimes with skin or muscle, is transferred from another area, such as the lower leg, and its blood vessels are connected in the neck.
May suitSelected extensive defects or situations needing both bone and soft-tissue replacement.
Main tradeoffThis is major surgery with donor-site recovery and a risk of blood-vessel blockage or flap loss.
Artificial TMJ replacement
Replaces severely damaged joint components with a prosthesis.
How it worksThe surgeon removes affected joint structures and places components that recreate the jaw-side and skull-side surfaces.
May suitSelected patients with advanced joint destruction, fused joints, or failed prior treatment.
Main tradeoffInfection, persistent pain, device wear, or loosening may lead to further treatment or revision.
Biologic joint reconstruction
Uses your own tissue to rebuild selected joint structures.
How it worksA tissue or bone graft is shaped and positioned according to the joint defect.
May suitSelected circumstances in which age, growth, anatomy, or previous surgery favors tissue-based reconstruction.
Main tradeoffGrafts can change over time, and growth or long-term movement may be unpredictable.
Most TMJ disorders do not require joint reconstruction. Ask why the proposed operation is appropriate for the specific damage shown on your examination and imaging. [1].
Are plates the same as a reconstructed jaw?
No. Plates can stabilize bone or bridge a gap, but they do not replace living bone or teeth. Their role may be temporary or long term, depending on the overall plan.
Could I need more than one operation?
Yes. Tumor treatment, infection control, reconstruction, bite adjustment, and dental restoration may occur in stages. A staged plan can also change if healing or tissue health is different than expected.
04 · Results
What may improve and what may remain
Function
The aim is a usable, stable jaw—not a promise of normal movement.
- Chewing, mouth opening, and bite stability may improve, depending on the original damage.
- Rehabilitation and dental restoration may be needed before you can use the reconstructed jaw fully.
Comfort
Structural repair does not guarantee pain relief.
- Joint-related pain may improve, but muscle or nerve pain can remain.
- Ongoing pain care may be part of treatment even when reconstruction heals well.
Facial support
Reconstruction can address lost support, with limits.
- Swelling can hide the developing contour for months.
- Scars, asymmetry, and soft-tissue differences may remain; additional procedures may be discussed.
Results depend on the diagnosis, prior operations, tissue health, and the reconstruction used. Discuss functional goals separately from pain and appearance goals. [3]
05 · Recovery
Planning your recovery
Recovery at a glance
- Stay after surgery
- Determined by Your Surgeon
- Initial recovery at home
- Varies by Individual
- Return to desk work
- Varies by Procedure and Work Activity
- Light daily activities
- Based on Individual Recovery
- Strenuous exercise
- Based on Surgeon Clearance
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Recovery differs substantially between a joint replacement and a larger jaw reconstruction with a donor site. Your team's written plan should cover nutrition, mouth care, movement, and follow-up.
Step 1 · Day of surgery
Treatment day
After anesthesia, the team monitors breathing, bleeding, and pain. A transferred tissue flap may need frequent blood-flow checks. Feeding support and the level of monitoring depend on the operation.
Step 2 · First days to weeks
Early recovery
Swelling, fatigue, and limited eating are common. Hospital discharge depends on safe breathing, nutrition, mobility, and wound care. Donor-site needs may also affect readiness.
Step 3 · Following weeks
Rehabilitation
Diet progression and jaw exercises must match the repair. Some reconstructions need protection, while others need early guided movement. Do not start stretching without clearance.
Step 4 · Months and beyond
Longer-term healing
Your team follows bone healing, joint movement, bite, and hardware. Dental restoration or additional surgery may come later. Returning to work does not mean healing is complete.
Planning everyday activities
ActivityGeneral planning contextWhat affects the plan
EatingPlanning context: You may need liquids, soft foods, or temporary feeding support.What affects it: The repair's stability, swallowing safety, and nutrition needs determine progression.
Work and schoolPlanning context: Time away may range from weeks to longer after extensive reconstruction.What affects it: Fatigue, speech demands, medications, and physical job duties affect timing.
Exercise and liftingPlanning context: Activity increases gradually with clearance.What affects it: Jaw healing and any leg, hip, or other donor-site repair may limit activity differently.
Jaw movementPlanning context: Follow a procedure-specific movement or therapy plan.What affects it: Too much strain can threaten a repair; too little movement may worsen stiffness in some cases.
Follow your surgical team's instructions rather than a general recovery schedule. Ask your surgical team whether compresses are appropriate and exactly how to use them.
Before your procedure
- Review scans, the diagnosis, and whether the plan treats the jaw bone, joint, or both.
- Share all medicines, supplements, allergies, and previous anesthesia problems; ask which medicines need adjustment.
- Discuss nicotine use and a cessation plan, since nicotine can interfere with healing.
- Arrange dental evaluation and discuss whether teeth or dental appliances affect the plan.
- Ask about nutrition, possible feeding support, and care for any donor site.
- Arrange transportation, help at home, and follow-up or rehabilitation appointments.
Will my jaws be wired shut?
Not always. Some plans use elastics, a splint, or temporary fixation; others do not. Ask how your jaw will be supported, how you will eat, and what to do if vomiting or a breathing problem occurs.
Why might rehabilitation differ between patients?
A healing bone graft may need protection from force, while a reconstructed joint may need guided movement to limit stiffness. Your surgeon and therapist should give you a coordinated plan.
06 · Safety
Risks and what your clinician assesses
Swelling, bruising, soreness, fatigue, temporary eating difficulty, and altered sensation can occur. The amount and duration depend on the operation. New or worsening symptoms should not automatically be treated as routine healing.
Bleeding and infection
Bleeding, fluid collections, or infection may require medication, drainage, or another operation. Infection involving hardware can be difficult to treat.
Bone or tissue healing problems
Bone may not unite, a graft may shrink or fail, or a tissue flap may lose its blood supply. Urgent surgery or further reconstruction may be needed.
Nerve injury
Numbness of the lip or chin, altered sensation, or weakness affecting facial movement can be temporary or permanent.
Persistent pain or limited function
Pain, stiffness, an altered bite, or difficulty chewing may remain or worsen. Further therapy or surgery may be considered.
Hardware, prosthesis, and donor-site problems
Plates or joint components can become exposed, loosen, wear, or fail. A donor site may develop pain, weakness, scarring, or mobility limitations.
Anesthesia and major-surgery complications
Breathing problems, blood clots, and heart or lung complications are possible. Your medical history and the operation's extent affect these risks.
Discuss these risks and your individual health history with your surgeon. [3]
What your clinician assesses
- The diagnosis, extent of bone or joint damage, bite, and mouth opening
- Previous surgery, radiation, infection, and local tissue blood supply
- General health, nutrition, nicotine use, and anesthesia or clotting risks
- Growth status, donor-site suitability, dental needs, and ability to participate in rehabilitation

08 · Questions
Common questions
Will reconstruction change how I look?
It can change jaw support and contour, especially when bone is missing. The main priorities may be disease treatment and function. Ask which appearance changes are intended and which differences may remain.
Can both jaw joints be replaced?
Sometimes. Each joint needs assessment, and symptoms on both sides do not automatically mean both need replacement. Imaging, examination, and previous treatment guide the recommendation.
Will an artificial joint last for life?
No device can be promised to last a lifetime. Wear, infection, loosening, or other problems may require revision. Regular follow-up helps monitor its function.
Can jaw alignment surgery replace reconstruction?
Not when missing or severely damaged structures need replacement. Alignment surgery moves existing jaw bones; reconstruction rebuilds them or the joint. Some patients need elements of both.
