1. Envelope Flap:

• Design: A straight horizontal incision along the gingival margin without vertical releasing incisions.

• Use: Widely used for simple extractions, implant placements, and small cyst removal.

• Advantages: Minimal disruption to blood supply and easier to close with fewer sutures.

• Disadvantages: Limited access, especially for posterior or deeper structures.

2. Triangular Flap (Three-cornered Flap):

• Design: A horizontal incision along the gingiva with one vertical releasing incision.

• Use: Common for impacted third molar surgery or apicoectomy.

• Advantages: Provides wider access than the envelope flap while preserving good blood supply.

• Disadvantages: Slightly more difficult to close and can cause more postoperative swelling.

3. Trapezoidal Flap (Four-cornered Flap):

• Design: A horizontal incision with two vertical releasing incisions.

• Use: Often used for more complex surgical procedures requiring wide exposure, such as bony impaction surgery or jaw cyst removal.

• Advantages: Provides excellent access to surgical sites.

• Disadvantages: Greater tissue dissection, which can result in increased swelling and postoperative discomfort.

4. Semilunar Flap:

• Design: A curved incision made in the mucosa above the surgical site without involving the gingival margin.

• Use: Often used for apicoectomy or accessing periapical lesions without disturbing the attached gingiva.

• Advantages: Minimal disruption to gingival tissue, making it ideal for esthetic areas.

• Disadvantages: Limited access, especially for larger surgical sites.

5. Y-shaped Flap:

• Design: An incision shaped like a “Y,” often used in the palate or areas where a circular lesion or access is needed.

• Use: Typically employed for palatal surgery or excision of large lesions like torus palatinus.

• Advantages: Provides good access to midline palatal areas.

• Disadvantages: More complex to close and can result in increased postoperative discomfort
