Principles of Surgical Exodontia Flashcards
Should the base of a flap be wider or narrower than the free margin?
Wider
How do you determine the width of an envelope flap?
Should be 2 teeth anterior and 1 tooth posterior to the area of surgery
How far from the involved defect should a full thickness incision be placed?
6-8mm
Will there be more or less bleeding with a full thickness flap compared to a partial thickness?
Less because subperiosteal is less vascular
Should you make a flap buccally or lingually to the Md 3rd molar?
Buccally, because the lingual nerve could be cut if lingual incision is made
What structure should you avoid damaging apically of md premolars?
Mental nerve
When should releasing incisions be made?
ONLY when necessary
Should a releasing incision be made anteriorly or posteriorly to working site?
anteriorly
Avoid crossing what when making releasing incisions?
bony prominences (i.e. canine prominence)
Releasing incisions should start where?
at the free gingival margin at the line angle of the tooth (not papilla, not prominence)
4 corner flaps have how many releasing incisions?
two
What kind of flap would you use for apical surgery?
Semilunar flap (made with apex of semilunar shape pointing toward the crown of involved tooth)
What kind of flap would you probably use for removing palatal tori?
Palatal Y flap
What blade should you use to start a mucoperiosteal flap?
No. 15 blade
Where is the blade placed to make a mucoperiosteal incision?
In the sulcus
