hydroxyapatite (mineral 60%), 25% organic material- collagen type 1, non-fibrous ECM- the fibre in collagen gives strength to the mineralised structure. 15% water

what does the alveolar and basal bone do?
Alveolar bone= supports the tooth
Basal bone= forms the structure itself of the jaw bone
2 of 21
what bone gradually disseapers after an extraction?
After taking a tooth out, the alveolar bone gradually disappears. Leaving just the basal bone

what lines the socket
lamina dura
4 of 21
what is in the microscopic bone structure
Lamellae (cementing lines and osteocytes)
- Circumferential: outside of most cortical bone
- Concentric: organised in Haversian systems/osteons
- Interstitial: remnants of old lamellae
5 of 21
what are the 2 types of bone formation
Endochondral ossification
Cartilage- calcified cartilage- bone
Intramembranous ossification
Condensation of mesenchymal cells
Osteoblasts- produce osteoid matrix
Woven bone
Primary osteon formation
6 of 21
what do osteoblasts, osteocytes, osteoclasts do?
osteoblasts:produce osteoid matrix.
osteocytes:Trapped osteoblasts (cf cementocytes), cell processes, linked by gap junctions, cells vital
Osteoclasts:breakdown organic matrix- enzymes
Pain – to be expected! They will be sore, pain. Normal to be in pain for 2-3days. But if it gets worse come back in.
Bleeding- if its continuously happening we’ll have to see
Bruising- can be seen on cheek, neck, chest
Swelling- different for everyone.

what are the post op instructions
• Avoid rinsing mouth for 24 hours (to get a clot established if this not formed more prone to dry socket)
• Avoid alcohol today (otherwise bleeding)
• Avoid smoking (otherwise dry socket)
• Bite on clean cotton or tea towel for 15 mins if bleeds
• How t

for what teeth do you stand behind the patient for an extraction?
You only stand behind for lower right side
16 of 21
what are elevators used for?
To expand socket and loosen tooth
17 of 21
what is the upper Universal force used for?
to extract any upper teeth
- Simple beaks to engage all single rooted teeth
If you could engage the furcation then you could take out upper molars but it is not specifically designed for molars
18 of 21
what forces would be used for a very badly broken down upper molar
upper cohort forcep
19 of 21
If you had 1 forcep to choose for the lower arch
Lower universal forcep
20 of 21
how does the lower molar force work
The lower molar forcep has two pointed beaks because is going to take a two rooted molar tooth, where there’s a mesial and distal root so that the points of the peaks engage bifurcation between the mesial and the distal root. = more efficient tool for tak
