Lecture 16

Question 1

definne implantation

Answer 1

insertion of an alloplastic material into the body for therapeutic diagnostic, prosthestic, or experimental

Question 2

define replanation

Answer 2

reinsertion of a tooth back into its jaw socket after removal

Question 3

define transplantation

Answer 3

transfer of a body part from one site to another

Question 4

what are the types of implant design?

Answer 4

1. endosteal
2. superiosteal
3. transosteal
4. epithelial implant

Question 5

what is an endosteal blade implant?

Answer 5

• device placed into the alv and or basal bone of mand or max
• not around anymore, causes bone loss

Question 6

what is a subperiosteal implant?

Answer 6

employs an implant substructure and superstructure

• placed beneath periosteum overlying bony cortex
• used where there is inadequate bone for endosseous implant
• disadvantages: slow rejection of implant, difficult retrievability, bone loss

Question 7

describe a transosteal implant:

Answer 7

• combines endost and superiost. components
• penetrates cortical plates and passes through full thickness of alv bone
• onl for ant mnd and for support of denture
• aka transmnd. and staple bone implant

Question 8

describe an epithelial implant

Answer 8

• inserted into oral mucosa
• disadv: painful healing and the requirment for continual wear
• very limited

Question 9

attachment mech of implants?

Answer 9

osseointegration

Question 10

what are the components of an implant?

Answer 10

post (cylinder)/fixture–replaces root
abutment (post extension)–mechanically attached to post
crown

Question 11

criteria for clinical success of dental implants?

Answer 11

1. mobility of implant (<1 mm when tested)
2. no evidence of radiolucency
3. bone loss <1/3 the height of the implant
4. any infx, damage, inflamm, must be amenable to tx
5. success rate must be 75% + after 5 yrs of functional service

Question 12

what are the components of implants?

Answer 12

1. metallic (Ti or Ti6Al4V, stainless steel, or Co-Cr-Mo)

2. ceramic and ceramic-coated implants
