Question 1

What is the process on the maxilla and mandible that contains the alveoli for the root(s) of each tooth?

Answer 1

The Alveolar Process

Question 2

What is the process on the mandible that creates the TMJ? This is FOUNDATIONAL anatomy!

Answer 2

CONDYLAR Process

Question 3

What is the process on the mandible where the temporalis muscle attaches? (MUY IMPORTANTE!)

Answer 3

Coronoid Process

Question 4

What is the bone in between alveoli?

Answer 4

InterDENTAL Septum

Question 5

What is the bone in-between the ROOTS of a posterior?

Answer 5

InterRADICular Septum

Question 6

What is the process that forms the “cheek bone”

Answer 6

Zygomatic Process

Question 7

What is the process that joins the hard palate?

Answer 7

The Palatine Process

Question 8

What is the name for the compact bone that surrounds the entire root of the tooth?

Answer 8

The Alveolar Bone

Question 9

Which cortical plate on the mandible cross section is concave? Which plate is convex?

Answer 9

Concave: Labial Cortical Plate; Convex: Lingual Cortical Plate

Question 10

What is the region where the cortical plate meets the alveolar bone?

Answer 10

The Alveolar Crest

Question 11

What is the “though layer” of alveolar bone surrounding the root?

Answer 11

Lamina Dura

Question 12

About how thick is the PDL attaching alveolar bone to cementum?

Answer 12

0.1mm

Question 13

What two cell types make PDL?

Answer 13

Fibroblasts & Cementoblasts

Question 14

What type of connective tissue proper is the PDL?

Answer 14

Dense Irregular

Question 15

Are there blood vessels in the PDL?

Answer 15

Yes! Lose them, lose the tooth.

Question 16

What type of collagen fiber are Sharpy’s fibers? How can you tell in a picture?

Answer 16

Sharpy’s fibers are type I collagen and they have a really distinct “banding” pattern to them.

Question 17

What are areas on the alveolar bone that have bundles of connections to sharpy’s fibers?

Answer 17

Bundle Bone(so same area as Alveolar Bone & Lamina Dura)

Question 18

Which nerve innervates the PDL of both the Maxilla and Mandible?

Answer 18

V. Trigeminal

Question 19

What are the 4 types of nerve endings found in the PDL?

Answer 19

1.Free Nerve Endings 2.Ruffini’s Endings 3.Coiled Endings 4.Encapsulated-Spindle Type

Question 20

What are the “stair-like” like interconnections of blood vessels that supply the PDL? What is another example in the body?

Answer 20

ANA-STO-MO-SES. Coronary Arteries, and “Roundabout” example in Brain

Question 21

What were the three break down regions for blood supply in the alveolar area? (remember the slide?)

Answer 21

1.PDL Supply 2.Alveolar Bone Supply 3.Supraperiostial supply

Question 22

What are the fibers found in the PDL that are very distinct from the type I collagen fibers? Which direction do they run? What type of fibers might they be? Main function?!

Answer 22

OXYTALAN fibers. They run vertically from Apex of Root to Cervical Region of Root. Immature ELASTIC fibers. FXN: Translate FORCE!

Question 23

What happens to the colorization of PDL when pressure is applied?

Answer 23

Hyalinization (Like fingernail, pushing blood supply away)

Question 24

What are the 5 Priniciple Fiber Groups of the PDL!?

Answer 24

1.Alveolar Crest Group 2. Horizontal Group 3. Oblique Group 4. Apical Group 5. Interradicular Group

Question 25

Where do the Alveolar Crest Fibers INITIALLY form? How do they develop?

Answer 25

They start down by Hertwigs Root Sheath Epithelium. They go from oblique to horizontal to oblique.

Question 26

What are the 5 types of GVL (my made up abbrev.). What layer of the mucosal membrane is the GVL located?

Answer 26

1.Dentogingival(Cerv.Cementum->L.Propria) 2. Alveologingival (Alv. Crest->L.Propria) 3.Circular(Ring around the neck) 4.Dentoperiosteal (Tooth down OVER the periosteum of the alveolar process) 5.Transsepital(Tooth->tooth)

Question 27

What are the two different threads for on an implant?

Answer 27

Thin threads at the cervical end are for the compact alveolar bone where as the thick threads toward the apical end are for the spongy bone.

Question 28

What type of junctional proteins are we trying to create between the implant and the surrounding bone?

Answer 28

Hemidesmosomes!
