As an oral and maxillofacial surgeon, I’ve found that mastering tooth sectioning techniques is crucial, especially in complex cases like horizontally or mesioangular impacted wisdom teeth. Two techniques I rely on are hemisectioning and coronectomy sectioning, each with its own strategic advantage.

When I perform a hemisection (as described in Peterson’s Principles of Oral and Maxillofacial Surgery), I use a surgical handpiece to section the tooth through the crown and into the interradicular space—between the roots. By dividing the tooth into distinct crown-root components, I can elevate each piece more conservatively. This reduces the stress on surrounding bone structures. Elevators are used to carefully deliver each segment, minimizing trauma—something Peterson’s emphasizes as essential to post-op healing.

Alternatively, in select cases, coronectomy (also covered in Peterson’s) is my go-to. Here, I carefully remove the crown first, leaving the root fragments behind initially. This can be advantageous when removing the roots poses a risk to the inferior alveolar nerve. After the crown is extracted, I address the roots separately or allow them to remain if conditions are right—a nerve-sparing approach that Peterson’s outlines for high-risk cases.

These techniques highlight that every extraction must be tailored. Whether we’re splitting crowns or strategically leaving roots, patient safety and long-term outcomes guide every decision.
