Oral surgery and orthodontics Flashcards
What soft tissue surgery is done for ortho
- frenectomy
- impacted canines (buccal apically repositioned flap, palatal open exposure)
- impacted premolar exposures
what hard tissue surgery is done for ortho
- impacted canines
- premolars
- other extractions
- submerged retained primary teeth
- implants
- mini-implants
- orthognathic surgery
options for impacted canines
- leave alone and monitor
- extract
- exposure and ortho alignment
- transplant
indications for canine transplant
- cannot get a result by exposure and traction
- potential damage to other teeth
- space avaliable or can be made avaliable
- older patient seeking quick solution
where do we ideally want the canine to erupt and why
- into attached gingiva or will get a red gingival margin
what is a common cause of unerupted premolar (not hypodontia)
early loss of E as 6 tends to drift mesially and 4 distally
how would you describe these canines
kissing canines
why would you apically reposition a flap
if there is lots of attached mucosa which you want to preserve. Take some attached mucosa and put it up higher so will come back down when the tooth erupts
what have they done here
repositioned a flap apically and sutured
why will this lead to a poor result
they have exposed the 23 without the use of an apically repositioned flap (not preserved attached mucosa), poor gingival margin
what are 2 methods of exposing a canine palatally
- open exposure
- closed exposure + chain
common surgery on frenum
- V-Y fernoplasty
why can implants be useful for orthodontics
as an ideal orthodonic anchor:
1. patient compliance unnecessary
2. absolute anchoarge as no PDL
3. easily used under a variety of tx modalities
4. easily placed
5. removable, if necessary
what types of implants are there
what do mini-implants look like
what do palatal mini implants look like
what is a corticomy
- technique to facilitate tooth movement
- very rarely done now
- where you weaken the bone so that teeth will move faster than in dense cortical bone
