Reconstruction plates for the jaw: what they do and how they last | CION Cancer Clinics
A reconstruction plate is a strip of titanium screwed along the jaw after part of the bone is removed. It holds new bone in place while it heals, or bridges the gap on its own. Most plates stay in for life without trouble. This page explains the types, living with a plate, the signs worth reporting and what to ask your surgeon. CION Cancer Clinics’ surgical oncologists in Hyderabad can talk this through with you.

The short answer
What does a reconstruction plate do in jaw surgery?
A reconstruction plate is a strip of titanium screwed along the jaw to hold it in shape after part of the bone is removed. It either holds new bone in place while it heals, or bridges the gap on its own.
Why the jaw needs holding
The lower jaw is a single curved bone. When a section is cut out, the two remaining ends are pulled by the chewing muscles and drift out of line. The bite shifts, the chin can sink to one side and eating becomes harder. A plate keeps the ends where they belong.
What titanium means for you
Titanium is light, strong and well tolerated by the body. It does not rust. Most plates stay in for life and you do not feel them. They do not set off most airport scanners, and CT and MRI scans can usually still be done, though the metal can blur nearby parts of the picture.
When a plate alone is not enough
A plate without new bone carries all the chewing force itself. Over years it can loosen, crack or push through the skin or gum, particularly at the front of the jaw or after radiotherapy. That is why many surgeons prefer to rebuild larger gaps with living bone, using the plate as support.
How plates are used
What kinds of plate might your surgeon plan?
The plan depends on how much bone is removed, where, and what the surgeon rebuilds it with.
Plate holding a bone flap
New bone, often from the leg, is shaped to fit the gap and fixed to the jaw with a plate or several small plates. Once the bone heals, the plate carries far less load.
Bridging plate with soft tissue
A longer plate spans the gap and is covered by a flap of skin and muscle, without new bone. The operation is shorter.
Sometimes considered when
- A long operation is less safe
- The gap is on the side of the jaw
Custom-made plate
Some centres bend or print a plate to match your own jaw using scans taken before surgery. Ask your centre whether they use this and what difference it would make in your case.
Small plates only
After a marginal mandibulectomy, where only the top rim of bone is removed and the jaw stays in one piece, a large plate is often not needed at all.

What do the terms about plates mean?
- Reconstruction plate
- A thicker titanium plate strong enough to span a gap in the jaw.
- Miniplates
- Small, thin plates used to join pieces of bone together.
- Plate exposure
- Part of the plate showing through the gum inside the mouth or through the skin of the face or neck.
- Occlusion
- How your upper and lower teeth meet when you bite. The plate helps keep it lined up.
- Osteoradionecrosis
- Bone that breaks down after radiotherapy because its blood supply has been damaged. It can loosen screws.
Over time
What happens to the plate after surgery?
-
The first weeks
The face and neck are swollen, and the plate may feel like a hard ridge under the skin. Soft food and careful mouth cleaning protect the wounds while they close over the metal.
-
Healing of the bone
If a bone flap was used, it slowly joins the remaining jaw over months. X-rays or scans at follow-up show how that is going.
-
Radiotherapy, if needed
Radiation can be given with the plate in place. It makes the skin and gums thinner and slower to heal, so the team watches the area over the plate closely during and after treatment.
-
Long-term follow-up
At each visit the surgeon looks inside the mouth and feels along the jaw. Tell them about any new sore, discharge or loose feeling, even if it seems small.
-
Teeth, later on
Dentures or implants may be possible once healing is complete. The dentist needs to know exactly where the plate and screws sit.

Commonly believed
What do people believe about jaw plates, and what is true?
Most jaw plates are left in for life. They are removed only if they cause a problem, such as exposure, infection or loosening. Taking out a plate that is working well is not routine.
Titanium plates do not stop radiotherapy, CT or MRI. The metal can make some pictures less clear near the jaw, so tell the scan team it is there. They adjust for it.
A plate showing through usually means the tissue over it has thinned or broken down, often after radiotherapy. It is not by itself a sign of cancer returning. It still needs to be seen by your surgeon soon.
For some people a plate alone is the sensible choice. For larger gaps, especially at the front, a plate without bone is more likely to cause trouble over the years. Your surgeon can explain which suits your situation.
Worth a call
Which signs around the plate should you report?
- Metal visible inside the mouth or through the skin
- A sore on the gum or skin over the jaw that does not heal
- Pus, a bad taste or a smelly discharge from the mouth or neck
- New swelling, redness or heat along the jaw
- A clicking, moving or loose feeling when you chew
- Your bite suddenly feels different
Being straight with you
What can this page not tell you, and what should you ask?
This page cannot tell you which plate, if any, will be used in your operation, or how likely your plate is to cause trouble. That depends on the size and position of the cancer, whether new bone is used, the health of the skin and gums and whether radiotherapy is planned.
Questions worth taking to the surgeon
Ask whether the plan is a plate with new bone or a plate alone, and why. Ask what happens if the plate becomes exposed or loose later. Ask how radiotherapy might affect the area over the plate. Ask who to contact if a sore appears months after surgery.
For the family
Plate problems can appear long after the hospital stay has faded from memory. Keep the discharge summary and operation notes safe, and carry copies to any dentist or local doctor. If you travel from a district outside Hyderabad, ask which checks can be done closer to home.

Common questions about jaw reconstruction plates
Will I feel the plate under my skin?
You may feel a firm ridge along the jaw with your fingers, especially once the swelling settles and if the skin is thin. Most people stop noticing it in daily life. Cold weather makes some people more aware of it. A plate that becomes painful or starts to show should be checked.
Will the plate set off the airport metal detector?
Titanium plates in the jaw rarely set off airport detectors. If one does, a short explanation is usually enough. Carrying a copy of your discharge summary or a note from your surgeon can make it easier, particularly on international journeys.
Can I have an MRI with a titanium plate?
Usually yes. Titanium is not attracted by the MRI magnet in the way some other metals are. It can blur the pictures close to the jaw. Always tell the scan centre you have a plate, and bring your operation notes if you have them.
What happens if the plate breaks or comes loose?
A loose screw, a cracked plate or a plate pushing through the skin needs to be seen by your surgeon. Sometimes it can be watched. Often the plate is removed or replaced, and some people need a further reconstruction with bone. The right step depends on the cause and your health at the time.
My father had radiotherapy. Is his plate more at risk?
Radiotherapy makes the skin, gums and bone over the plate thinner and slower to heal, so problems such as exposure are more likely than without it. Good mouth care, avoiding tobacco and attending dental checks help. Report any new sore early rather than waiting for the next visit.
Can I have dental implants near the plate?
Sometimes. Implants go into bone, so they are more often possible where a bone flap was used. The plate or screws may need to be moved to make room. Your surgeon and a dentist experienced with cancer patients decide this together after healing and any radiotherapy.
Does the plate make eating harder?
The plate itself does not usually limit eating. What affects chewing is the amount of jaw, tongue and teeth removed, and any stiffness from surgery or radiotherapy. Very hard food puts strain on a plate without bone, so your team may advise softer food for longer.
Is the plate covered by insurance or Aarogyasri?
Plates and screws are usually part of the operation package when surgery is covered. Aarogyasri, CGHS, ECHS and EHS are accepted, and most cashless insurers are empanelled. Ask whether a custom-made plate is covered, and call the helpline to check your cover before admission.
