Perio Flaps Flashcards
The union of
connective tissue with a root surface
that has been deprived of its original
attachment apparatus. i.e. Reunion of
connective tissue with a root surface which
has been pathologically exposed.
New Attachment:
The reunion of connective
tissue with a root surface on which viable
periodontal ligament tissue is present.
Reattachment:
The healing of a wound that does
not fully restore the architecture or
function of the part.
Repair:
all soft tissue
including the periosteum is reflected
exposing the underlying bone. (Most
commonly used flap, and also called a
mucoperiosteal flap.)
Full thickness flap:
epithelium
and some connective tissue is reflected,
leaving periosteum and some connective
tissue overlying the bone.
Partial (split) thickness flap:
Removal of the
connective and epithelial
attachment circumferentially
with a curette
Curettage:
Removal
of the connective
and epithelial
attachment
circumferentially
with a scalpel
ENAP:
The excision of the soft
tissue wall of the periodontal pocket. The
incision forms an external bevel or surface
that is exposed to the oral cavity.
Gingivectomy:
Gingival deformities are
reshaped and reduced to create a normal
and functional form. The incision creates an
external bevel.
Gingivoplasty:
Indications for _____
Elimination of suprabony pockets which
can’t be adequately debrided without tissue
removal.
Elimination of suprabony pockets if the
pocket wall is fibrous and firm and therefore
will not shrink after non-surgical therapy.
Access for restorative with suprabony
pockets.
These three indications are usually
corrected by flap surgery for access
. Elimination of gingival enlargements (most
common indication for gingivectomy).**
Elimination of asymmetrical or unesthetic
gingival topography (gingivectomy and/or
gingivoplasty).
Exposure of unerupted teeth when
adequate keratinized tissue is present.
Gingivectomy
_____ contraindications
Access is needed to infrabony defects.
Base of pocket is apical to MG junction, or
when keratinized tissue is inadequate so
that a gingivectomy would remove all of the
keratinized tissue.
Severely inflamed tissue (needs scaling
and root planing)
Esthetics (anterior maxilla)
Anatomical preclusion (lack of keratinized
tissue)
Gingvectomy
_______ Advantages and
Disadvantages
Advantages
Relatively simple and fast.
Disadvantages
Limited applicability (suprabony defects)
Longer healing period (4-5 weeks)
More post-operative discomfort
Less effective than flap surgery (no
access to osseous defects)
Gingivectomy
Surgical debridement of the root surface
and removal of granulation tissue from
osseous defects following reflection of a
mucoperiosteal flap.
Modifications:
Modified Widman
open flap debridement
____ is a modification of an open flap debridement where only the root is accessed thru a flap where no bone is exposed
Modified widman
_____ indications
Advanced disease where access is needed
to root surfaces and osseous defects.
Where regeneration may be possible.
To preserve tissue for esthetics.
As an exploratory procedure or as part of
the non-surgical phase of treatment for
fibrous tissue.
Less post-operative discomfort.
Open flap indications
_____ contraindications
Patient is unable to tolerate a surgical
procedure.
Increased tissue recession may result in
esthetic compromise.
Potential of root caries and root sensitivity
due to greater root exposure post-
surgically.
Open flap debridement
_____ can occur due to compromised
blood supply due to over-thinning
of flap or vascular compromise
Source of healing is the PDL,
flap margin, and underlying bone
Flap necrosis
______ is a modification of
subgingival curettage with flap reflection.
Objectives
Minimal tissue recession by not reflecting
past the alveolar crest.
Conservation of alveolar bone - no
osteoplasty or ostectomy
New Attachment ???? (long J.E. actually
is the result)
Modified Widman
Indications
Moderate disease
Infrabony defects
Patient with high caries rate or root
sensitivity
Anterior esthetic areas
Contraindications
Severe disease and greater access
needed.
Modified Widman
Advantages
Access to root surfaces
Esthetics??
Minimal recession
Primary closure???
Disadvantages
Flat or concave post-operative tissue
contours
Modified widman
Objective is to gain access to interproximal
defects in the maxillary anterior region
with minimal recession.
Technique
Palatal flap
Incisions only in the facial interproximal
areas, with no direct facial incisions
Debridement and then closure
Anterior curtain
Indications
Maxillary anterior region with
interproximal or palatal osseous defects
and no facial bone loss.
Esthetic concern.
Contraindication
Facial bone loss.
Anterior curtain
