This document provides information about flap surgery procedures in periodontics. It discusses the purposes of flap surgery, which include gaining access to deeper periodontal structures, relocating the frenulum, maintaining attached tissue, and eliminating pockets. It outlines the indications for flap surgery as well as contraindications. It then describes principles of flap design such as base width and length, blood supply, and avoiding tension. Different types of flaps and incisions are presented, along with techniques for suturing flaps. The document provides an overview of flap surgery procedures in periodontics.

Phase I periodontal therapy is the first in the chronologic sequence of procedures that constitute periodontal treatment. It is also referred to as cause related therapy or non-surgical periodontal therapy.

ROS is a substractive method of having positive bone architecture. it includes osteotomy and ostectomy procedures. osteotomy is to remove non supporting bone and ostectomy is to remove supporting bone for having positive bony architecture. there is definitive osseous surgery and compromise osseous surgery. transgingival probing is a method of determining osseous topography. various hand and rotary instruments are use for this procedure.
Furcation involvement is a common sequela of severe chronic periodontal disease. Its effective management has a profound influence on the outcome of periodontal therapy.

Minimally Invasive Surgery & Acellular Dermal Matrix to Correct Gingival Rece...Edward Gottesman
Successful root coverage for single or multiple teeth can be achieved with a minimally invasive tunneling technique and acellular derail matrix (Alloderm®).
Presentation given by Dr. Edward Gottesman, periodontist in New York, New York at the American Academy of Periondontology Meeting in San Francisco in September, 2014.

Gingivectomy means excision of the gingiva.
Gingivoplasty is a reshaping of the gingiva to create physiologic gingival contours with the sole purpose of recontouring the gingiva in the absence of pockets.
Flap Design, one from important topics in Oral Surgery Syllabus, student must be know:
Definition Incision and flap.
Principles of flap design.
Enumerate types of flap with advantages, disadvantages, indications...

Periodontal plastic surgery is defined as the surgical procedures performed to correct deformities of the gingiva or alveolar mucosa. It includes widening of attached gingiva,
deepening of shallow vestibules, resection of the aberrant frena, depigmentation of gingiva.In all of these procedures, blood supply is the most significant concern and must be the underlying issue for all decisions regarding the individual surgical procedure.
2. Purpose
1. To gain access to deeper periodontal
structures with direct vision.
2. Relocation of the frenulum
3. Maintenance of the attached tissue
4. Pocket elimination and regeneration
3. Indications
• Pockets > 5mm persisting after phase I therapy
• Bony pockets and interdental craters
• Bony lesions in the furcations
• Need for surgical crown lengthening
• When to open up a flap? complicated
morphology like:
– Deep and narrow pocket
– Difficult to achieve the correct angle
10. Principles of Flap Design
• Local flap
1.outlined by a surgical incision
2.carries its own blood supply
3.allows surgical access to underlying tissues
4.can be replaced in the original position
5.can be maintained with sutures and is expected
to heal
Used in oral surgical, periodontic, and
endodontic procedures to gain access.
11. Principles of Flap Design
• Complications
A. Flap necrosis
B. Flap Dehiscence
C. Flap Tearing
D. Injury to Local Structures
12. Principles of Flap Design
A. Flap necrosis
1. Base > Free margin
• to preserve an adequate blood supply
• unless a major artery is present in the base
2. Width of Base > Length of Flap*2
• less critical in oral cavity, but length < width
• a long, straight incision with adequate flap reflection
heals more rapidly than a short, torn incision.
3. An axial blood supply in the base
4. Hold the flap with a retractor resting on intact
bone to prevent tension.
13. Principles of Flap Design
B. Flap Dehiscence
1. The incisions must be made over intact bone
2. If the pathologic condition has eroded the
buccocortical plate, the incision must be at least 6 or 8
mm away from it.
3. The incision is 6 to 8 mm away from the bony defect
created by surgery.
4. Gently handle the flap's edges
5. Do not place the flap under tension
6. Do not cross bony prominences, ex: canine eminence
15. Principles of Flap Design
C. Flap Tearing
• Envelope flaps
– an incision around the necks of several teeth.
– extends 2 teeth anterior and 1 tooth posterior.
If not provide sufficient access…
• Vertical (oblique) releasing incisions:
– extends 1 tooth anterior and 1 tooth posterior.
– started at the line angle of a tooth.
– carried obliquely apically into the unattached gingiva.
– If cross the papilla localized periodontal problems
16. Principles of Flap Design
D. Injury to Local Structures
• Mandible: lingual n. & mental n.
17. Principles of Flap Design
D. Injury to Local Structures
• Maxilla: greater palatine a. & nasopalatine n./a.
21. Basic Incisions
2. inversebeveled
Modified flap
incision to the crest
(mucoperiosteal)
of bone.
Requires adequate 1. gingivectomy
attached Incision for
keratinized gingiva pocket reduction
On the palate,
enlarged tissue, or
with limited access
25. Types of Mucoperiosteal Flaps
2. Three-corner flap
1 tooth anterior
1 tooth posterior
Greater access in an apical direction,
especially in the posterior aspect of the
mouth
28. 1. Inverse bevel incision 0.5~2mm, extending to the alveolar
crest. Thins gingival tissue and permits compete closure of
the interdental osseous defects postoperatively.
29. 2. Flap reflection. Full thickness mucoperiosteal flap is
reflected to permits visualization.
30. 3. Crevicular incision between the hard tooth and the
diseased pocket epi., to the depth of the junctional epi.
34. 1. Sulcularly, crestally, or full-thickness flap labially positioned
inverse beveled incision to bone
2. Flap completed, reflected off bone
3. Flap is apically positioned and sutured
35. A: The internal bevelled,
scalloped incision is used
for pocket elimination
through apical
repositioning of the flap.
B: The flap
positioned apically for
pocket elimination.
36. 1. Crestal incision with blade, partial-thickness flap parallel to long
axis of tooth
2. Flap raised by sharp dissection, periosteum retained over bone
3. Flap is apically positioned at or below alveolar crest
37. 1. No alveolar mucosa is
present on the palate to
permit apical positioning.
2. Pocket elimination by
palatal flap that just
covers the contours of
the bone to eliminate
osseous defects.
3. Requires skill and
experience.
38. Osteoplasty
Osseous grooving,
peprmits better
adaption of flaps to
facilitate plaque
removal alter
healing
