E2- Oral surgery Flashcards
Exodontics means
tooth extraction
Indications for exodontics
T/F: we must take rads pre and post extraction
TRUE
Extraction of multi-rooted teeth is different from single rooted how?
same except:
section the tooth at furscation of roots
elevate and remove each root segment individually
Most common extraction complications
root breakage
displacement of root tips into nasal cavity or mandibular canal
hemorrhage
dehiscence and fistula formation
iatrogenic jaw fracture
T/F: we must ALWAY remove retained root tips
FALSE: type II and III are primary exceptions but inform O
Retained root tips can serve as a ____ for periapical inflam
nidus- a place in which something is formed
Create a ___ flap for surgical extraction
buccal (vestibular) mucoperiosteal flap
The depressions between the ridges of bone formed by roots in the alveolar process on the mandible and maxilla?
Juga
What blade should we use for tooth extractions?
15
diastema
a space or gap between two teeth
T/F: we can make incision right over tooth/center of alveolus
FALSE- a problem if oronasal fistula present
What is the biggest cause of oral surgery failure?
_************TENSION************_
Aftercare of gingival flaps
broad spectrum antibiotics if preexisting dz
soft food 2 weeks
nothing with a crunch for 10-14 days
no toys or hard treats 2 weeks
recheck in 10-14 days
Causes of oronasal fistula
dental dz and extractions
pressure necrosis from foreign body
complication of sx, radiation therapy, hyperthermia
trauma- electrical cord burns, bites, gunshot
What is a non-oral sign of an electrical burn?
pulmonary edema, esp cats chewing electrical cords
CS of oronasal fistula
inciting cause
nasal discharge
sneezing
aspiration pneumonia
Keys to successful oronasal fistula repair
avoid tension
two layer technique: continuity of nasal and oral mucosa restored
single flap technique: position suture line over supported tissue
Indications for a single flap technique on oronasal fistula
acute fistulas (non-healed)
defects too large to allow 2 layer closure
Double flap technique indications
congential defects
chronic fistulas where oral mucoperiosteum has healed to nasal mucosa
Salvage procedures for oronasl fistulas
intraoral appliances: acrylic appliances, nasal septal button
Highest incidence of jaw fractures?
symphysis and ramus- weakest areas = CATS
When fixing a jaw fracture remember to?
maintain occlusion- have to be able to close mouth, drink, eat soft foods
____ is the tension side of jaw, opposite side is the compression side of jaw
dental arcade
