Oral Surgery & Orthodontics Flashcards
What soft tissue oral surgeries may orthodontics ask oral surgery to perform?
- frenectomy
- expose impacted canines
- expose impacted premolar exposures
How can impacted canines be exposed?
- buccal apically repositioned flap
- palatal open exposure
What hard tissue oral surgeries may orthodontics ask oral surgery to perform?
- extraction of impacted canines
- exposure of impacted canines with bone removal
- XLA of premolars
- exposure of impacted premolars with bone removal
- submerged retained primary teeth
- implants
- mini-implants
- orthognathic surgery
What treatment options are there for patients presenting with impacted canines?
- leave alone & monitor
- extract the canine (unlikely)
- surgical exposure & orthodontic alignment (mini-implants & corticotomy)
- transplant
What are some indications for canine transplant?
- we cannot reasonably get a result by exposure & traction
- there is a potential for damage to other teeth
- space is available or can be made available without premolar extraction
- the older pt who is seeking a quick solution
What is the problem with tooth transplant procedures?
Damage to PDL
- leads to ankylosis after transplantation
What dental treatment option provides the qualities of an ideal orthodontic anchor?
Implant
Why are implants an ideal orthodontic anchor?
- absolute anchorage as there is not periodontal ligament
- easilt used under a variety of treatment modalities
- easily placed
- removable if necessary
What can occur after having palatal flap raising surgery to extract impacted canines?
Nasopalatine nerve bundle affected
- numbness of gingiva of anterior maxillary teeth
If a canine transplant is carried out, what must the patient use afterwards?
Splint (titanium trauma splint)
- 2 weeks
- then RCT
What tends to happen after teeth are transplanted?
Ankylosis (no matter how careful you are)
Why do oral surgeons avoid luxating impacted teeth?
causes ankylosis
What is a ‘kissing canine’ ?
when a canine tooth is impacted and reach across arch to reach other canine
Why should relieving incisions be broad based?
Increased blood supply to flap
What is an open exposure?
cut a hole & leave it open (commonly done palatally)
