Surg Flashcards
Straight elevator ?301)
Lever
Most common
Triangular elevator (cryer)
Wheel and axle for removing broken root
Pick elevator
Wedge
What stroke for bone files?
Pull stroke
Hemostat ca needle holder
Hemostat = long thin curved beaks with lined hatching
Needle holder = short stout crisshatched beaks
Suture
Placed from MOVABLE to non-movable, purpose to immobilize a flap. Simple interrupted easiest
Silk stitching con
Wicking
Where is the fulcrum when luxatinf a tooth and what happens?
Fulcrum is alveolar bone and causes expansion of bone
Semi lunar incision used for what
Apicoectomy. Apical a displaced flap is impossible in MX palatial
Screw retained implant
Better for restricted restorative space and can be removed later
Cement retained implant crown
Cement may be trapped subgingivally and cause perio-implantitis
Abutment is attached separately to implant
Worst bone and best bone for implants?
Type 1 in A MN is best, dense cortical bone
Type 2 in P MN
Type 3 in A MX
Type 4 in P MX is worst, soft medullary bone
Implant placement space needed
1mm to everything EXCEPT
1.5 to natural tooth
3 to another implant
2mm to IAN
5 to mental nerve due to loop
One vs two stage surgery
One = implant and healing abutment in one visit
Two = implant and cover screw in frost appointment, abutment at next visit
Desires orientation of ginigival fibers next to implant?
Parallel with cuff
Most common MN fractures? Evaluated best by?
Condylar > angle > symphysis
*pano
Mid face fractures best evaluated with
CBCT
Zygomaticomaxillary complex fracture
Tripod fracture, blow to malar eminence
BLEEDING UNDER CONJUNCTIVA
How are mandible fractures ideally treated?
ORIF = Open reduction (fragments exposed surgically) and internal fixation (bone plates to hold bones together); occlusion guides surgeon
Axis 1 vs axis 2 biopsychosocial model of pain
Axis 1 = bio, somatic, acute
Axis 2 = psychosocial, chronic
Pain pathway
1) transduction
2) transmission
3) modulation
4) perception
1) transduction - pns to CNS
2) transmission - CNS to thalamus
3) modulation - limitation of pain flow
4) perception - the experience
Trigeminal neuralgia
Tic doulourex
Post-menopause, 50+
Unilateral- electric, sharp, shooting and episodic
Txt with anticonvulsants (carbamazepine)
Atypical odontalgia
Phantom toothache
Second to deafferentation (removal of nerve) due to endo
Postherpetic neuralgia
Potential sequels of heroes zoster
Anticonvulsants, antidepressant, sympathetic blocks
