IMPACTION

W – winter WAR lines
H – height of mandible outline – easy for extraction
A – angulation of tooth – mesio angular – easiest
(most common) - disto – difficult ( least common)
R – root type – convergent root – easy
F – follicle – large follicle – easiest

Mesio - angular, converging roots, large follicle “EASY”
Disto - angular, divergent roots, small follicle, “DIFFICULT”

Horizontal – requires sectioning of tooth**********
QN Palatal root of upper 6 is the most pushed in max. sinus.
QN Factors that make surgery more difficult:- Distoangular, thin follicle, narrow PL, & divergent
curved.
