Periodontal Flap Procedures Part II Flashcards
Surgical debridement of the root surface and removal of granulation tissue from osseous defects following reflection of a mucoperiosteal flap:
open flap debridement
List the modifications of an open flap debridement:
- modified Widman
- curtain procedure (maxillary anteriors)
The curtain procedure (modified open flap debridement) is used for:
maxillary anteriors
What is the most important aspect of open flap debridement?
Access!
What treatment would be indicated for the following scenario?
- Advanced disease where access is needed to root surfaces and osseous defects
- situations in which REGENERATION may be possible
- to preserve tissue for esthetics
- as an exploratory procedures or as part of the non-surgical phase of treatment for fibrous tissue
Open-flap debridement
Open flap debridement allows for less:
post-op discomfort
Give an example of when we may use an open flap debridement as an exploratory procedure?
the we think we have a fractured root and we need to get in there to see
The following are contraindications for:
- 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 contraindications
What type of incision is indicated for open-flap technique?
What type of incision is NOT indicated due to being ineffective?
Intrasulcular incision; step back
In open flap debridement technique, ____ are thinned to a uniform thickness
papillas
What type of flap is reflected in open-flap technique?
mucoperiosteal
What type of incisions can be used in an open-flap technique?
vertical incisions
In an open-flap technique, _____ are placed dependent on the extent of defects and amount of pocket reduction planned
palatal incisions
What determines if palatal incisions are placed during open flap debridement technique?
extent of defects & amount of pocket reduction planned
Flap necrosis may result from:
compromised blood supply due to over-thinning of flap or vascular compromise
