Periodontal flap is a section of gingiva and/or mucosa surgically elevated from underlying tissues to provide visibility and access to bone and root surface.

Classification/Types of Flap

According to thickness of flap/bone exposure after flap reflection:

• Full thickness/mucoperiosteal flap: All the soft tissues including periosteum are elevated.
• Partial thickness/mucosal flap/split thickness flap: reflection of only the epithelium and a layer of underlying connective tissue.

Question 2. Write short answer on internal bevel gingivectomy.
Answer.

“Role of advanced bone loss in recommending gingivectomy”

Undisplaced flap differs from modified Widman flap in that the soft tissue pocket wall is removed with the initial incision; thus it is considered as an “internal bevel gingivectomy”.

• The undisplaced flap and the gingivectomy are two different techniques which surgically removes the pocket wall.
• To perform this technique without creating mucogingival problem, periodontist should determine that an amount of attached gingiva should be left after removing the pocket wall.
