BOP, inflammation, increased probing depths associated with clinical attachment loss and possibly rx bone loss

supra bc cant get to the bone

Question 13

explain the difference between full thickness flap and partial thickness flap

Answer 13

Answer 16

allows direct access to bone, easier and faster

Question 17

benefits of split thickness

Answer 17

maintains periosteum which allows you to do apical positioning of the flap leading to preservation of keratinized tissue. technique sensitve bc flap is thinner, risk of perforation
