extractions Flashcards
what do you need for an extraction to be indicated?
clinical +/- radiographic assessment
indications for extraction
unrestorable tooth - gross caries - advanced PDD (bleed on ext) - tooth/root fracture - severe TSL - pulpal necrosis - apical infection symptomatic PE teeth traumatic position - e.g. U8s buccally - biting cheek ortho indications - usually 4/5s interference with denture construction
upper extraction forceps
6 - beaks in line with handles root straight universal L molar R molar 3rd molar/Bayonet
straight upper anterior forceps
1, 2, (3)
straight handles
upper root forceps
v thin beaks
retained roots
upper universal forceps
3, 4, 5
curved handle and beak
upper molar forceps
“beak to cheek”
engages furcation
2 buccal roots, 1 palatal
lower extraction forceps
4 - beaks perpendicular to handles root universal molar cowhorns
lower root forceps
retained roots
v thin beaks
lower universal forceps
1,2,3,4,5
lower molar forceps
2 beaks
cowhorn forceps
broken down molars you can’t easily grip with molar forceps
v narrow and pointy
squeezing action should elevate tooth. if tooth doesn’t come out then move forceps - no mobilisation with cowhorns
use with care as can cause crown or root fractures
often use in younger pts - bone softer
Upper bayonet 3rd molar forceps
Z
straight handle
wider tip to allow you to extract U8s
might not give a good grip as anatomy varies a lot
Upper bayonet root forceps
curved handle
Z
narrow tips - grab retained upper molar roots
pt positioning lowers
quite upright
