-advanced disease where access is needed to root surfaces and osseous defects

-situations in which regeneration may be possibly

-to preserve tissue for esthetics

-as an exploratory procedure or as part of the non-surgical phase of treatment for fibrous tissue

Q

What is the source of healing for an open flap?

A
  1. PDL
  2. Flap margin
  3. Underlying bone
17
Q

What is the primary source of healing for open flap?

18
Q

A modification of subgingival curettage with flap reflection:

A

Modified Widman flap

19
Q

Where is the FIRST incision started in the modified widman technique?

A

First incison is started 0.5-1.0mm apical to the gingival margin and “aimed” at alveolar crest

20
Q

In the modified widman technique minimal removal of interproximal tissues occurs for:

A

primary closure

21
Q

Where is the SECOND incison in the modified widman technique?

A

intrasulcular

22
Q

Where the THIRD incision made in the modified widman technique?

A

made following the alveolar crest

23
Q

Objective of this modification of open flap technique is to gain access to interproximal defects in the maxillary anterior region with minimal recession:

A

anterior curtain

24
Q

The technique for the anterior curtain procedure includes:

  1. ____ flap
  2. incisions ONLY in the ____ areas, with no direct facial incisions
  3. ____ and then closure
A
  1. palatal flap
  2. facial interproximal areas
  3. debridement
25
What procedure would be indicated in the given situation: -maxillary anterior region with interproximal or palatal osseous defects and no facial bone loss with esthetic concern
Anterior curtain
26
What is the only contraindication for anterior curtain procedure?
Facial bone loss
27
When trying to determine the best treatment for your patient you should consider: (4)
1. diagnosis 2. goal of therapy 3. limitations of each technique 4. personalized therapy
28
The goal of all periodontal surgery is to:
access defects
29
Success of all periodontal surgical procedures is dependent upon:
patient's home care & maintenance
