Crown Lengthening Flashcards
T/F: Esthetic crown lengthening is indicated for hyper mobile lip or skeletal problem.
False
What are the two problems with invading the biologic width with a restoration?
Gingival recession or chronic inflammation
What is the textbook general rule for how much sound tooth structure should be left coronal to the alveolar crest?
4 mm
What is the benefit of doing crown lengthening with an inverse bevel gingivectomy?
The wound is not exposed
Done when there is adequate keratinized tissue and adequate BW after surgery
Why would you use an apically positioned flap for crown lengthening and what is the negative?
If there is not adequate KT for gingivectomy
Tissues may rebound
How would you approach crown lengthening if there is only 2 mm from the CEJ to the alveolar crest?
You would have to use an apically positioned flap with Osseous resection to maintain biologic width
T/F: If biologic width is established during surgery, tissue rebound will be prevented.
True
What is the objective of functional crown lengthening?
Establish sound tooth structure for restorations
How long until restorations can be done after crown lengthening?
6 weeks
