2. Introduction to Implants

Question 1

is bone resorption faster in the max or mandible?

Answer 3

mandible (4x)

Question 4

height or width first? (bone resorption)

Answer 4

width then height

Question 5

maxilla resorbs ____ and ____

Answer 5

upward and inward

Question 6

mandible resorbs ____ and ____

Answer 6

downward and outward

Question 7

jaw discrepancies with bone resorption tend towards ____ skeletal relationship

Answer 7

class III

Question 8

the patient with an implant supported fixed prosthesis can exert a similar force to that of a patient with ____

Answer 8

fixed restorations on teeth

Question 9

eposteal (subperiosteal) implant

Answer 9

on / around bone

metal framework attaches on top of the jaw bone but underneath the gumt issue

Question 10

transosteal implant

Answer 10

through bone (top and bottom)

metal pin or a u-shaped frame that passes through the jawbone and gum tissue into the mouth

Question 11

endosteal implant

Answer 11

into bone

Question 12

implant fixture

Answer 12

screw

alloplastic material or device surgically placed into oral tissues underneath the mucosal or periosteal layer or within the bone for functional therapeutic or esthetic purposes

Question 13

transgingival abutment

Answer 13

seat for implant crown

connection above neck of the implant used to provide support and / or retain any fixed or removable dental prosthesis

Question 14

dental prosthesis

Answer 14

implant crown

fixed or removable, provisional, or definitive

Question 15

cover screw

Answer 15

used to seal the dental implant body during healing phase after surgical placement

Question 16

healing abutment

Answer 16

limited time, assist in healing or modification of the adjacent tissues

Question 17

cover screw vs healing abutment

Answer 17

cover screw - usually short, submerged under soft tissue during healing phase

healing screw - taller, exposed in oral cavity during healing phase

Question 18

transfer foping

Answer 18

component of dental implant system used to provide relationship of dental implant to the alveolar ridge and adjacent dentition or other

Question 19

scan body

Answer 19

digital impression coping
used for digital impression

Question 20

implant replica / analogue

Answer 20

-replication of dental implant connection
-not intended for implantation placement
-need to fabricate prosthesis
-replication of superior portion of an implant abutment
-provide an exact form of dental implant abutment during fabrication of a prosthesis in lab

Question 21

temporary abutment

Answer 21

interim dental implant abutment

used with endosteal dental implants to alter abutment design before a definitive dental prosthesis is fabricated

Question 22

temporary abutment materials

Answer 22

PMMA or PEEK
most contain titanium alloy base
titanium or titanium alloy

Question 23

prosthetic abutment fixed

Answer 23

support and / or retain a fixed dental prosthesis

Question 24

stock abutment

Answer 24

prefabricated, usually comes with package

Question 25

custom abutment

Answer 25

custom made, requires lab work

Question 26

prosthetic abutment removable

Answer 26

support and / or retain a removable dental prosthesis

Question 27

abutment (screw) driver

Answer 27

hand instrument specifically made to assist in insertion and securing of a dental implant abutment to the superior portion of a dental implant for specific support systems

Question 28

attachment screw

Answer 28

abutment to screw - used to secure fixed dental prosthesis specific torque

Question 29

manual torque wrench

Answer 29

restorative torque wrench used to precisely apply a specific torque to a fastener bolt for fixation of an abutment, dentures or prosthetics on a dental implant

Question 30

surgical drill

Answer 30

used for osemony preparation for implant placement in surgical site

Question 31

depth gauge / PIN

Answer 31

used for checking osteotomy preparation in surgical ite

Question 32

implant motor

Answer 32

rotary machine for implant surgery -different RPMs -cooling (irrigation) -provide different torque

Question 33

osseointegraiton

Answer 33

apparent direct attachment or connection of osseous tissue to an inert, alloplastic material without intervening fibrous connective tissue results in apparent direct connection of an exogenous material's surface and the host bone tissues, without intervening fibrous connective tissue present

Question 34

dental implant materials

Answer 34

pure titanium titanium alloy ceramix (zirconia)

Question 35

narrow diameter implant

Answer 35

<3.5mm

Answer 38

7-10mmm

Question 39

regular implant length

Answer 39

>10mm

Question 40

one stage implant placement advantages

Answer 40

-only one surgery -reduced cost -reduced time -direct clinical monitoring of implant -minimize microgap problem -higher patient acceptance

Question 41

one stage implant placement disadvantages

Answer 41

-non-esthetic in the anterior region -tissue augmentation procedures difficult if not impossible

Question 42

two stage implant placement advantages

Answer 42

-minimal risk of infection -minimal apical migration of eptihelium -no occlusal overload -max primary stablity -tissue augmentation procedures

Question 43

two stage implant placement disadvantages

Answer 43

-two surgical procedures -higher cost -healing period longer -lower patient acceptance -stage II surgery - additional bone loss
