What is the incision angle in Gingivectomy?

In a gingivectomy, the incision angle is typically made at 45° to the tooth in an apical direction. This angle is optimal because it allows for effective removal of the excess gingival tissue while minimizing trauma to the adjacent structures. The apical direction ensures that the incision appropriately follows the natural contour of the gums, facilitating proper healing and reducing the risk of postoperative complications such as bleeding or infection.

Using a 45° angle helps maintain the gingival architecture and ensures that the depth of the incision is adequate to reach the underlying tissues without compromising adjacent anatomical features. This technique is crucial for achieving a satisfactory aesthetic outcome and promoting healthy gingival margins after the procedure.

Other angles, such as the options indicating a 60° or 90° angle, may result in either inadequate tissue removal or increased trauma to surrounding areas, while an angle of 30° to the horizontal plane would not align well with the natural anatomy of the gingiva, potentially complicating the surgical outcome.
