Answer 1

Natural tooth:
a) enamel
b) dentin
c) pulp

e) PDL

Dental implant:
a) fabricated crown
b) abutment
c) implant
d) bone

Question 2

What are the differences when comparing the periodontium of a tooth to a dental implant? (4)

Answer 2

1. less vascularity
2. No PDL
3. Fewer gingival fibers
4. Collagen fibers parallel the implant

Question 3

When discussing the difference between periodontium of a tooth to a dental implant a difference includes “collagen fibers parallel the implant” why is this different?

Answer 3

Fibers do not insert into cementum like a natural tooth

Question 4

Label the image of the natural tooth:

Answer 4

a) enamel
b) sulcus
c) sulcular (crevicular) epithelium
d) junctional epithelium
e) connective tissue
f) cementum
g) bone

Question 5

Label the image of the dental implant:

Answer 5

a) titanium implant
b) sulcular epithelium
c) junctional epithelium
d) connective tissue
e) bone

Question 6

When comparing the periodontium of a natural tooth vs. dental implant, what is present in the natural tooth, that is absent in the dental implant?

Answer 6

Enamel & cementum

Question 7

Because a dental implant receives no vascular supply from the PDL, resulting in an overall less vascular supply, this results in:

Answer 7

Less immune system regulation
