What type of incision is commonly used during resective osseous surgery?

The external bevel incision is commonly used during resective osseous surgery because it allows for optimal access to the underlying bone and periodontal tissues. This type of incision is made at an angle away from the bone, which helps to preserve the soft tissue while simultaneously providing a clear view of the osseous structures. It facilitates the removal of bone and allows for the necessary surgical procedures to be performed effectively.

Using an external bevel incision can also minimize the amount of soft tissue that needs to be removed, which promotes better healing and can improve the overall aesthetic outcomes post-surgery. It is particularly beneficial in surgeries aimed at reshaping the alveolar bone and removing any pathological tissue that may be contributing to periodontal disease.

In contrast, other types of incisions may not provide the same level of access or control needed during these specific surgical procedures. For example, internal bevel incisions are typically used for flap reflection in certain periodontal surgeries, but they might not be as effective for resective procedures where bone needs to be accessed directly. Sulcular incisions primarily target the pocket and may not adequately expose osseous structures, while crestal incisions are usually made along the crest of the bone and may not facilitate the necessary access for resective techniques.
