What is Hemi-section?
- Hemi-section is performed on teeth with two or more roots (most commonly Molar teeth).
- It is the section of one or more roots that have an infection source or fracture present.
- Root Canal filling of the remaining root/s is necessary in hope of saving the tooth.
- A crown is required where Root canal and Hemi-section treatments are successful.
- A surgical approach to gain visible access of the roots is the most predictable technique for success
Indications for Hemi-section?
- Root canal filling treatment hasn’t been considered successful.
- The root/s of a tooth have a source of infection remaining.
- The root/s have a fracture present.
- The patient wishes to try and save a tooth rather than have extraction.
- The surviving root is accessible and able to be treated with Root canal.
- The surviving root is able to respond to a post-crown restorative treatment.
- May prevent the loss of the tooth, avoiding bone loss in the area, teeth shifting and opposing teeth over-erupting into the space.
- If successful, the patient will retain their ability to eat and chew as normal.
- Avoids replacement options such as Dentures and Bridges which can be detrimental to other teeth.
- Where roots are fused together or very curved (poor candidate for Hemi-section).
- Patients may be unwilling to undergo surgical and root canal treatments.
- Timely procedure.
- Superseded by implants
- Increased stress on other teeth (because of the loss of 50% of the tooth).
- Infection, swelling, bruising after the surgical procedure.
