Periodontal Flap Definition
Periodontal flap
- It is a section of the gingiva and/or the mucosa surgically separated from the underlying tissues to provide visibility and access to the bone and the root surface
Periodontal Flap Important Notes
1. Basic requirements of flap
- It should provide adequate exposure to the surgical area
- The flap must have a broad base and good vascular supply
- When placed back after surgery flap should rest on healthy bone
2. Advantages of the flap technique
- Provides adequate visibility and accessibility to the root deposit
- Eliminates or reduces pocket depth
- Expose the area to perform regenerative procedures
3. Condition and the preferred flap
4. Apically displaced flap
- It can be used for pocket elimination or widening the zone of attached gingival
- The pocket wall is transformed into an attached gingival
- It increases the length of the clinical crown and is not indicated for palatal pockets
- The width of the attached gingiva is increased by approximately half the pretreatment pocket depth

According to the placement of Flap
- Non-displaced flap:
- The flap is returned and sutured in its original position
- Displaced flap:
- The flap is placed apically, coronally, or laterally to its original position.
According to the management of the papilla
- Conventional flap:
- The interdental papilla is split beneath the contact point between the teeth
- Modified Widman flap is a conventional flap
- Indications:
- Narrow interdental area
- Papilla preservation flap:
- It incorporates the entire papilla
- Indications:
- Esthetics
- Regenerative procedures

periodontal flap surgery Indications Of Flap Surgery
- To increase accessibility to root deposits
- To eliminate or reduce pocket depth by resectioning the pocket wall
- To expose the area to perform regenerative methods
- To reshape soft and hard tissues to physiologic architecture
Question 4. Apically Displaced flap.
Answer:

Question 5. Incisions.
Answer:
Horizontal incision:
1. Internal bevel incision:
- Extend: Marginal gingiva to the bone crest
- Synonyms: First incision
- Reverse bevel incision
- Advantages: Eliminates pocket
- Preserves remaining structures
- Provides good adaptation of tooth to bone
- The blade used: No. 15 and 11 – surgical scalpels
2. Crevicular incision:
- Second incision
- Extend – Base of the pocket to the crest of bone
- Blade – No.12B
- Effect – Formation of tissue wedge
Interdental incision:
- Third incision
- Purpose to separate the collar of the gingiva
- An instrument used – Orban knife
Vertical Incision:
- On either side of the horizontal incision
- Extend – Beyond the mucogingival junction
- Indications: Displaced flap
- Isolated deep pockets

Periodontal Flap Viva Voce
- Apically displaced flaps cannot be performed in the palatal aspect of maxillary posterior teeth
- Unattached gingiva is absent in the palatal aspect of maxillary posterior teeth
- Widening of the attached gingiva as well as pocket elimination is accomplished by apically displaced flap
- An internal bevel incision is also called a reverse bevel incision
- The second incision in the periodontal flap is a crevicular incision
- The interdental incision is called the third incision
- After flap surgery fully epithelized gingival crevice occurs after 1 month.
- An undisplaced flap is essentially an excisional procedure of the gingival
