Term
True or False?
A flap may also be replaced to the original position. |

Term
True or False (2 statements)
The final location of the flap should be made before an incision has taken place. The flap location is determined by the goal(s) of therapy and the specific surgical technique to be done. |

The following are indications for...?
1. Teeth that have decayed or fractured below the gingival margin with impingement of the biologic width.
2. Excessive wear of the dentition. The clinical crown is inadequate for the retention of a cast restoration. (bulimic patient, chemical erosion)
3. An unesthetic gingival margin. “Gummy Smile” or uneven gingival margins.
4. Functional reasons; --- teeth with inadequate inter-occlusal space. |

| What are the 4 sequenced steps for crown lengthening surgery? |
|
Definition
1. Determine restorability of the tooth
(perio and prosthetic treatment plan)
2. If possible, have all restorative variables completed.
3. Crown lengthening surgery completed
4. Allow 6 -12 weeks for healing |
