Coronectomy, also known as partial tooth removal, is a specialised dental procedure tailored to manage impacted wisdom teeth that are in close proximity to the mandibular nerve. At St John & Elizabeth Hospital, our skilled maxillofacial surgeons adopt this less invasive technique to mitigate the risk of nerve damage, offering a safer alternative to full tooth extraction. This method not only alleviates discomfort but also preserves the integrity of the jawbone and surrounding nerves.

Also known as: sub-total tooth extraction, wisdom tooth crown removal

Everything You Need to Know

Coronectomy is ideally suited for patients where traditional wisdom tooth extraction poses a significant risk of nerve injury. Our maxillofacial experts remove the crown of the wisdom tooth, leaving the roots undisturbed to safeguard the mandibular nerve. This procedure is underpinned by our commitment to patient safety, minimising post-operative complications and promoting a quicker recovery.

Before The Procedure

Initial Consultation

Your oral care journey begins with an in-depth consultation with one of our maxillofacial surgeons, where your concerns and dental history are thoroughly discussed. This session is crucial for understanding the complexity of your case and for crafting a treatment plan that aligns with your needs.

Diagnostic Assessments

Accurate diagnosis is the cornerstone of a successful coronectomy. Expect to undergo detailed imaging assessments, such as X-rays or a CT scan, to precisely map the location of your wisdom tooth in relation to the mandibular nerve. These insights guide our surgeons in planning a precise and safe procedure.

Preparing for Your Treatment

Preparation for a coronectomy may include guidelines on eating, drinking, and medication adjustments prior to your procedure. Our team ensures you are fully informed on how to prepare for surgery, setting the stage for a smooth and effective treatment.

During The Procedure

Our approach to coronectomy is patient-focused and safety-oriented. The procedure involves:

Surgical Precision

Our maxillofacial surgeons employ state-of-the-art techniques to remove the tooth crown efficiently while meticulously preserving the nerve and root structure. This precision minimises the risk of nerve damage and promotes faster healing.
