Overview of CPT Code 21146: Injection of Bone Graft, Mandible
CPT Code 21146 refers to the injection of a bone graft into the mandible, which is the lower jawbone. This procedure is typically performed to promote bone healing and regeneration in cases of bone loss or defects.
When CPT Code 21146 is Used?
This procedure is indicated in various clinical scenarios.
- To treat bone defects resulting from trauma or injury.
- In cases of congenital malformations affecting the mandible.
- For patients undergoing dental implants where bone density is insufficient.
- To support the healing of fractures in the mandible.
Symptoms Indicating This Procedure
Patients may present with several symptoms that warrant this procedure.
- Pain or discomfort in the jaw area.
- Swelling or inflammation around the mandible.
- Difficulty chewing or speaking.
- Visible deformity or asymmetry of the jaw.
Causes and Risk Factors
Several factors can contribute to the need for a bone graft in the mandible.
- Traumatic injuries leading to bone loss.
- Chronic infections affecting the jawbone.
- Tumors or cysts in the mandible.
- Previous dental surgeries that may have compromised bone integrity.
Diagnostic Tests Before Procedure
Several diagnostic tests may be performed to assess the condition of the mandible.
- X-rays to evaluate bone structure and integrity.
- CT scans for detailed imaging of the jaw.
- MRI to assess soft tissue involvement.
- Bone density tests to determine the health of the bone.
Procedure Description
The procedure involves several key steps.
- Patient is positioned comfortably and anesthesia is administered.
- An incision is made in the gum tissue to access the mandible.
- The area is prepared, and the bone graft material is injected into the defect.
- The incision is closed with sutures, and the area is cleaned.
Preparation for the Procedure
Patients should follow specific guidelines before the procedure.
- Avoid eating or drinking for at least 8 hours prior to the procedure.
- Inform the surgeon of any medications or supplements being taken.
- Arrange for transportation home post-procedure due to anesthesia effects.
- Follow any specific instructions provided by the healthcare provider.
Recovery and Aftercare
Post-procedure recovery is crucial for healing.
- Rest for the first 24 hours and avoid strenuous activities.
- Apply ice packs to reduce swelling.
- Take prescribed pain medications as directed.
- Follow up with the healthcare provider for suture removal and assessment.
Possible Complications
As with any medical procedure, there are potential risks.
- Infection at the injection site.
- Allergic reaction to the graft material.
- Nerve damage leading to numbness or tingling.
- Failure of the graft to integrate with the bone.

Regular follow-up is essential for monitoring recovery.
- Initial follow-up within one week to check for complications.
- Subsequent visits at 2 weeks, 1 month, and 3 months post-procedure.
- X-rays may be taken to assess bone healing.
Alternative Treatments
There are non-surgical options available.
- Bone regeneration therapy using growth factors.
- Physical therapy to improve jaw function.
- Medication to manage pain and inflammation.
Home Care Tips
Patients can take steps to aid recovery at home.
