18
Q

A modification of subgingival curettage with flap reflection:

A

modified Widman

19
Q

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

A

First incision is started 0.5-1.0 mm 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 incision in the modified Widman technique?

A

intrasulcular

22
Q

Where is the THIRD incision in the modified Widman technique?

A

made following the alveolar crest

23
Q

Objective of this modified open flap technique procedure 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 facilities incisions
  3. _____ and then closure
A
  1. palatal flap
  2. facial interproximal areas
  3. debridement
25
Q

What procedure would be indicated for the given situation?

  • maxillary anterior region with interproximal or palatal osseous defects and no facial bone loss with esthetic concern
A

anterior curtain

26
Q

What is the ONLY contraindication for anterior curtain procedure?

A

facial bone loss
