8. ACCORDING TO STRENGTHENING
MECHANISM
Crack Tip
Interaction:
Obstacles In The
Micro Structure
Impede Crack Motion
By Reorienting Or
Deflecting The Plane
Of Fracture. www.indiandentalacademy.com

9. CRACK TIP INTERACTION e.g.
A. Leucite Crystals Reinforced.
I. Optec H S P.(Jeneric/Pentron)
Ii. Finesse.(Dentsply)
Iii. Ips Empress I.(Ivoclar)
B. Aluminium Oxide.
I. Hiceram.(Vita Zahnfabrik)

11. CRACK TIP
SHIELDING:
 Events triggered by the
high stresses in the crack
tip region act to reduce
the stress (ie) the
transformation
toughening and
microcrack toughening.
www.indiandentalacademy.com

12.  CRACK
BRIDGING:
Second Phase
Crystalline
Structure Acts
As A Bandage
To Prevent A
Crack From
Opening
Further.
A. Tetra Silicic Fluoro
Mica Crystals-
Dicor(dentsply)
B. Hydroxy Apatite
Crystals- Cerapearl.
(Kyocera)
