Mucogingival Surgery
Also named as periodontal plastic surgery
“Surgical procedures performed to correct or eliminate anatomic, developmental or traumatic deformities of
the gingiva or alveolar mucosa”
“Periodontal surgical procedures designed to correct defects in the morphology, position and/or amount of
gingiva surrounding the teeth”
“plastic surgical procedures for the correction of gingiva, mucous membrane relationships that complicate
periodontal diseases and may interfere with the success of periodontal treatment”

Strip Technique
Page 11

12. Jаffaя яaza Syзd Page 12
Connective Tissue Technique
Advantages of this technique include:
a. Donor site—Healing by primary intention is achieved because the donor material can be obtained from
connective tissue that is present beneath the palatal flap.
b. Color matching is better.

13. Jаffaя яaza Syзd Page 13
Combination Techniques
It can be performed as follows:
Remove a strip of tissue about 3 to 4 mm thick from the palate,
place it between two wet tongue depressors, and slice it longitudinally with a sharp BP blade.
Use a superficial portion that contains epithelium and connective tissue.
And the deeper portion that only consists of connective tissue.

14. Jаffaя яaza Syзd Page 14
Healing Of The Graft
I. Plasmatic Circulation Stage (2-3 Days):
Direct joining of capillaries between the graft and the recipient bed is seen and capillaries of the recipient bed
invade the graft.
Ii. Capillary Circulation Stage (4-5 Days):
Capillaries start functional circulation again.
The epithelium at this stage is almost desquamated and sparse.
Iii. Organization Stage (10-14 Days):
Organization is completed by growth of fibroblasts in the graft and in the recipient bed.
The network of capillaries become dense.
Regeneration of epithelium becomes active to complete the epithelialization
(wound healing is by secondary intention)

can be a full thickness (or) split thickness flap
Procedure
Step I : Internal bevel incision 0.5-1 mm from the crest of the marginal gingiva is given.
Step II : Crevicular incision and interdental incisions are placed.
Step III : Vertical incisions extending beyond the mucogingival junction are made so that the flap can
be displaced easily. Reflect the flap depending on the purpose (split thickness or full thickness).
Step IV : Debride the area and place the flap apical to its original position and suture.

two vertical incisions from the junction of the marginal and attached gingiva to approximately 12 mm from the
alveolar margin into the vestibule.
The vertical incisions are joined by horizontal incision.
A mucosal flap is elevated exposing the periosteum on the bone.
The periosteum is separated from the bone, starting from the line of attachment of the mucosal flap.
The periosteum including muscle attachments is transported to bone and is sutured to the inner surface of the
periosteum.

Root Coverage
Advantages for root coverage procedures
i. Reduces root sensitivity.
ii. Improves esthetics.
iii. Manage the defects resulting from root caries removal and/or cervical abrasions.
iv. Manage mucogingival defect which fail to respond to altering abusive tooth-brushing techniques and/ or
plaque removal.

Miller’s Classification (1985)
Class I:
Marginal tissue recession that does not extend to the mucogingival junction. There is no loss of bone or soft
tissue in the interdental area. This type of recession can be narrow or wide
Class II :
Marginal tissue recession that extends to or beyond the mucogingival junction. There is no loss of bone and
soft tissue in the interdental area. This type of recession may be wide or narrow.
Class III :
Marginal tissue recession that extends to or beyond the mucogingival junction. In addition, there is bone
and/or soft tissue loss interdentally or tooth may be malposed.
Class IV :
Marginal tissue recession extends to or beyond the mucogingival junction. With severe bone and soft tissue
loss interdentally and/or severe tooth malposition.

Type of recession Prognosis
Class I and II Good to excellent
Class III Only partial coverage can be expected
Class IV Very poor

Procedures For Root Coverage
1. Conventional procedures.
2. Regenerative procedures.
Conventional procedures
Depending on the width of the attached gingiva, i.e. if adequate width is present at the donor site the
following procedures can be selected:
a. Laterally (horizontally) displaced flap.
b. Double-papilla flap.
c. Coronally-positioned flap
If the donor site is associated with inadequate width:
i. Free soft tissue autograft.
ii. Subepithelial connective tissue grafts are available
Regenerative procedures:
Guided tissue regeneration (GTR) has been proposed.
Pedicle autografts:

26. Jаffaя яaza Syзd Page 26
Laterally (Horizontally) displaced flap
Advantages
a. One surgical site
b. Good vascularity of the pedicle flap.
c. Ability to cover isolated, denuded roots that have
adequate donor tissue laterally.
Disadvantages
a. Limited by the amount of adjacent keratinized attached gingiva.
b. Possibility of recession at the donor site.
c. Dehiscence or fenestration at the donor site.
d. Limited to one or two teeth with gingival recession.
Indications:
a. For covering the isolated denuded root.
b. When there is sufficient width of interdental papilla in the adjacent teeth.
c. Sufficient vestibular depth.
Contraindications:
a. Presence of deep interproximal pockets.
b. Excessive root prominence.
c. Deep or extensive root abrasion or erosion.
d. Significant loss of interproximal bone height.

Procedure for laterally displaced flap:
Step I : Preparation of the recipient site
Incision  3 insions  SRP of the recipient bed
thickness or full thickness reflection  short oblique
the flap, pointing more towards the recipient sit
Step II : Transfer the flap
Suturing to the adjacent gingival and
alveolar mucosa with interrupted suture
Step III : Protect the flap and donor site
periodontal pack for 1 week
Antibiotics  optional
Analgesic  mandatory

28. Jаffaя яaza Syзd Page 28
Double papilla flap
Indications:
1. When the interproximal papillae adjacent to the mucogingival problem are sufficiently wide.
2. When the attached gingiva on an approximating tooth is insufficient to allow for a Lateral Pedicle Flap.
3. When periodontal pockets are not present.
Advantages:
1. The risk of loss of alveolar bone is minimized because the interdental bone is more resistant to loss than is
radicular bone.
2. The papillae usually supply a greater width of attached gingiva than from the radicular surface of a tooth.
3. The clinical predictability of this procedure is fairly good.
Disadvantage:
Technique sensitive—Having to join together the small flap in such a way so that they act as a single flap

29. Jаffaя яaza Syзd Page 29

30. Jаffaя яaza Syзd Page 30
Coronally-repositioned flap
Indications:
• Esthetic coverage of exposed roots.
• For tooth sensitivity owing to gingival recession.
Advantages:
• Treatment of multiple areas of root exposure.
• No need for involvement of adjacent teeth.
• High degree of success.
• Even if the procedure does not work, it does not increase the existing problem.
Disadvantage:
There is a need for two surgical procedures if the zone of keratinized gingiva is inadequate

31. Jаffaя яaza Syзd Page 31

32. Jаffaя яaza Syзd Page 32

33. Jаffaя яaza Syзd Page 33
First Technique
Step 1 : Make two apically-divergent vertical releasing incisions
Step 2 : A split thickness flap is prepared on coronal side and full thickness flap is prepared apical to recession
Step 3 : Once the flap is reflected the root surfaces are debrided thoroughly. Some authors have suggested
the use of citric acid with a pH 1.0 for conditioning the root surface.
Step 4 : At the base of the inner surface of the flap, approximately 3 mm apical to the bone dehiscense, a
horizontal incision is made through the periosteum, followed by a blunt dissection into the lining mucosa to
release muscle tension. Now the mucosal graft can be easily positioned coronally at the level of
cementoenamel junction.
Step 5 : interrupted sutures and additional sling sutures can be placed to maintain the flap in place.
Step 6 : Periodontal dressing is placed to protect the wound during initial healing.

34. Jаffaя яaza Syзd Page 34
Second Technique (Semilunar flap)
Indication:
Small localized area
Advantages:
• No vestibular shortening, as occurs with the coronallypositioned flap.
• No esthetic compromise of interproximal papillae.
• No need for sutures.
Disadvantages:
• Inability to treat large areas of gingival recession.
• The need for a free gingival graft if there is an underlying dehiscence or fenestration.

35. Jаffaя яaza Syзd Page 35

36. Jаffaя яaza Syзd Page 36
Subepithelial Connective Tissue Graft
Indications:
• Where esthetics is of prime concern
• For covering multiple denuded roots
• In the absence of sufficient width of attached gingiva in the adjacent areas.
Advantages:
• High degree of cosmetic enhancement
• Incurs no additional cost for autogenous donor tissue
• One step procedure
• Minimal palatal trauma
• Increased graft vascularity.
Disadvantages:
• High degree of technical skills required.
• Complicated suturing

37. Jаffaя яaza Syзd Page 37
Technique
I. Preparation of recipient site:
The initial horizontal right angle incision is made into the adjacent interdental papillae at, or slightly coronal to
the cementoenamel junction of the tooth with an exposed root surface.  preserve the papillary blood supply
 A partial thickness flap is raised without vertical incisions  SRP  Root Conditioning with citric acid pH 1.0
or tetracycline HCl in a concentration of 250 mg mixed in 5 ml of sterile water  approximate mesio distal
width necessary for the graft is measured with a periodontal probe.
II. Excision of the donor tissue
1st
incision  horizontal incision 2-3mm apical to gingival margin
2nd
incision  parallel to the long axis of the teeth, 1 to 2 mm apical to the first incision
raise a full thickness periosteal connective tissue graft
III. Grafting to the recipient site:

Guided Tissue Regeneration Technique For Root Coverage
Indications
• Esthetic demand.
• Indicated for single tooth with wide, deep localized recessions.
• For areas of root sensitivity where oral hygiene is impaired.
• For repair of recessions associated with failing or unesthetic class V restorations.
Advantages:
• Techniques does not require a secondary donor surgical
site reducing postoperative discomfort.
• New tissue blends evenly with the adjacent tissue,
providing highly esthetic results.
Disadvantages:
• It is sensitive technique.
• Insurance of additional cost of barrier membrane.

Operations For Removal Of Frena
“A frenum is a fold of mucous membrane usually with enclosed muscle fibers, that attaches the lips and
cheeks to the alveolar mucosa and/or gingiva and underlying periosteum.”
Indications
To prevent:
1. The accumulation of irritants.
2. The deflection of the wall of periodontal pocket which may aggravate its severity.
3. Its interference with post-treatment healing.
4. Pocket formation.
5. Injury while brushing
