What describes an external bevel incision?

An external bevel incision refers to a surgical technique where the incision starts below the gum line and is directed coronally toward the surface. This type of incision is crucial in periodontal surgeries, as it effectively removes the outer layer of gingival tissue while preserving the underlying bone and other periodontal structures.

By starting below the gum line, the incision allows for better access to the underlying structures and facilitates procedures such as flap surgeries or gingivectomies. The coronally directed angle helps to minimize trauma to the surrounding tissue and promotes better healing outcomes, making it an essential technique in periodontal surgery.

Cosmetic purposes may be a factor in some surgical decisions, but external bevel incisions are primarily functional and focused on the restoration and preservation of periodontal health rather than purely cosmetic enhancements. Other options describe different techniques or do not accurately capture the described incision type.
