question

In 1996, World Workshop in Clinical Periodontics renamed mucogingival surgery as?

answer

"periodontal plastic surgery"

question

T/F: Mucogingival surgery was initially introduced in the literature by Friedman

answer

True

question

Define periodontal plastic surgery

answer

The surgical procedures
performed to correct or eliminate anatomic, developmental, or traumatic
deformities of the gingiva or alveolar mucosa

question

Define periodontal plastic surgery

answer

The surgical procedures
performed to correct or eliminate anatomic, developmental, or traumatic
deformities of the gingiva or alveolar mucosa

question

T/F: Mucogingival therapy is a broader term than periodontal plastic surgery in that it includes nonsurgical procedures

answer

True

question

What is the ultimate goal of mucogingival surgical procedures?

answer

Creation or widening of attached gingiva around teeth and implants

question

T/F: Attached gingiva is not synonymous with "keratinized gingiva"

answer

True

question

T/F: A
graft, either pedicle or free, is placed on a recipient bed
apical to the recessed gingival margin. No attempt is made
to cover the denuded root surface where there is gingival
and bone recession. Is a real procedure?

answer

True

Gingival augmentation apical to the area of recession

This enhances oral hygiene procedures

question

What is the ideal thickness of a free gingival autograft?

answer

Between 1.0 and 1.5 mm

question

This variant of the free gingival graft attains expansion of the graft by alternate incisions in opposite sides of the graft

answer

Accordion technique

question

When performing the strip technique, how wide should the strips of gingival donor tissue be?

answer

3 to 5 mm wide

question

T/F: In the strip technique, the sutured recipient site is suppose to be covered with aluminum foil and surgical dressing

answer

True

question

What is the technique where a deep strip graft is taken from the palate and is split into
both an epithelial-connective tissue strip and a pure connective
strip?

answer

Combination technique

question

ADM stands for?

answer

acellular dermal matrix

question

T/F: The periosteum along the apical
border of the graft is sometimes penetrated in an effort to prevent
postoperative narrowing of the attached gingiva

answer

True

question

Once completely healed, how much smaller do you expect the graft to be due to contraction of a free gingival autograft?

answer

50% smaller

question

What is the ADM (acellular dermal matrix), AlloDerm derived from?

answer

donated human skin

question

T/F: Alloderm contains epidermis

answer

False;

Consists of nondenatured 3-D arrangement of intact collagen fibers, ground substance, and vascular channels

question

What are the two surgical techniques suggested for the use of ADM (acellular dermal matrix) in treating gingival recession?

answer

1. Alternate papilla tunnel (APT) method
2. Papilla retention pouch (PRP)

question

In the APT (alternate papilla tunnel) method with use of ADM (acellular dermal matrix), why is the papilla in the anatomic midline always tunneled?

answer

Reduce tension and retraction of the recipient pouch

question

How far should one extend the graft during the APT (alternate papilla tunnel) with use of ADM (acellular dermal matrix)?

answer

The length of graft needed is measured and trimmed so that the graft will extend 3 mm past the last tooth with recession at each end of the prepared
site

question

What should the vertical dimension of the graft be during the APT (alternate papilla tunnel) with use of ADM (acellular dermal matrix)?

answer

6 to 8mm

question

In this surgical technique method for the use of ADM (acellular dermal matrix) in treating gingival recession, all papillae are tunneled

answer

PRP (Papilla retention pouch) Method

question

When making intrasulcular incisions for the PRP (Papilla retention pouch) method, how far past the treated teeth do you extend?

answer

In the PRP method, all papillae are tunneled. Initially, intrasulcular
incisions are made facial and proximal to all teeth to be treated plus an additional tooth at each end

question

T/F: The advantages of the PRP (Papilla retention pouch) method include enhanced retraction resistance, graft containment and wound stability

answer

True

question

How many days of systemic antibiotics is recommended for postoperative care for the alternate papilla tunnel (APT) method
or papilla retention pouch (PRP)?

answer

10 days

question

How many weeks of chlorohexidine mouthrinse is recommended for postoperative care for the alternate papilla tunnel (APT) method
or papilla retention pouch (PRP) in a free gingival graft?

answer

2 to 3 weeks

question

How long should no mastication or toothbrushing at surgical site for postoperative care for the alternate papilla tunnel (APT) method
or papilla retention pouch (PRP) when using ADM in a free gingival graft?

answer

No mastication or toothbrushing at surgical site for 2 to 3 weeks

question

When do you remove the surface sutures for postoperative care for the alternate papilla tunnel (APT) method
or papilla retention pouch (PRP) when using ADM in a free gingival graft?

answer

2 to 4 weeks

question

When do you remove the subgingival graft suture for postoperative care for the alternate papilla tunnel (APT) method
or papilla retention pouch (PRP) when using ADM in a free gingival graft?

answer

At 2 months

question

When using alloderm in a free gingival graft, fibrous organization of the interface between the graft and recipient bed occurs?

answer

Fibrous organization of the interface between the graft and recipient bed occurs within 2 to several days

question

How is the alloderm free gingival graft maintained initially?

answer

The graft is initially maintained by a diffusion of fluid from the
host bed, adjacent gingiva, and alveolar mucosa

question

When does revascularization of the alloderm free gingival graft occur?

answer

Revascularization of the graft starts by the second or third day. Capillaries from the recipient bed proliferate into the graft to form a network of new capillaries and anastomose with preexisting vessels

question

When is a thin layer of new epithelium present with an alloderm free gingival graft?

answer

A thin layer of
new epithelium is present by the fourth day, with rete pegs developing
by the seventh day

question

When is healing of an intermediate thickness (0.75 mm) Alloderm free gingival graft complete?

answer

10.5 weeks

question

When is healing of a thicker thickness (1.75 mm) Alloderm free gingival graft complete?

answer

16 weeks or longer

question

When does functional integration of an alloderm free gingival graft occur?

answer

17th day

question

Who originally described the connective tissue autograft?

answer

Edel

question

T/F: Healing of a free connective tissue autograft is done by secondary intent

answer

False;

In CT autograft, donor tissue is obtained from the undersurface of the palatal flap, which is sutured back in primary closure; therefore healing is by first intention

question

T/F: The apically displaced flap technique increases the width of the keratinized gingiva but cannot predictably
deepen the vestibule with attached gingiva

answer

True

The apically displaced flap technique
increases the width of the keratinized gingiva but cannot predictably
deepen the vestibule with attached gingiva

question

What three locations can the edge of an apically displaced flap be located in relation to bone?

answer

1. Slightly coronal to the crest of the bone
2. At the level of the crest
3. Two millimeters short of the crest

question

Which location of the edge of an apically displaced flap in relation to the bone produces the most desirable gingival contour?

answer

2mm short of the crest

answer

Miller Class I and II have good to excellent prognoses.

Miller Class IV has a very poor prognosis

question

When performing a free connective tissue autograft, the partial-thickness flap should be at least __mm apical to the receded area.

answer

When performing a free connective tissue autograft, the partial-thickness flap should be at least 5 mm apical to the receded area.

question

This procedure is indicated for larger and multiple defects with good vestibular depth and gingival thickness

answer

Subepithelial Connective Tissue Graft (Langer)

answer

True

question

In guided tissue regeneration technique for root coverage, how much of the marginal periosteum should be covered by the membrane?
