Q

What is the ultimate goal of the implant regarding the bone

A

for it to become anchylotic with the bone; establish a mucosal attachment

16
Q

What is good/poor bone quality

A

you want a mix of cortical and trabecular, cortical gives you the stability, while trabecular gives you the blood supply

17
Q

This increases surface area, and bone response is stronger to surfaces with irregularity values

A

porosity

18
Q

An implant should be surrounded with a minimum of how much alveolar bone thickness

A

1mm

19
Q

What are the minimum ridges of bone thickness between implant/implant and implant/tooth

A

implant/implant - 2mm

implant/tooth - 4mm

20
Q

The coronal part of an implant should be places approx. how many mm apical to the adjacent CEF

A

5mm

21
Q

Obtaining this between implants and teeth is critical

A

maximum parallelism

22
Q

Implants do not have this, which means they cannot tolerate horizontal forces

A

PDL

23
Q

An implant can be places at a maximum of this angle

A

20 degrees

24
Q

What are the two parts of transmucosal attachment

A
barrier epithelium (2mm)
zone of connective tissue (1-1.5mm)
25
Q

The collagen fiber bundles are in which direction corresponding to the implant surface

A

parallel

26
Q

The zone that is adjacent to the implant surface is rich from what

A

rich from fibroblast, but poor from blood vessels

27
Q

The zone that is in lateral direction and continuous with the first zone has fewer fibroblasts but is rich in what

A

collagen fibers and blood vessels

28
Q

The blood supply is coming from which blood vessels

A

supraperiosteal

29
Q

What is the difference between one and two stage implant placement

A

two stage = submerged tech.

one stage = non-submerged tech.

30
Q

This is the same that exists between implant and abutment

A

microgap; generally located at the alveolar crest

31
Q

Where does the biologic width on an implant exist

A

around unloaded and loaded non submerged one part titanium implants; approximately 3mm

32
Q

What are the 6 parameters used to evaluate peri-implant health

A

1; absence of mobility
2; radiographic examination
3; absence of bone loss ≥2mm/year following the first year
4; absence of any pain, complaint, or infection
5; functional and esthetic acceptance of implant
6; success rate of 94-98% following 5 years and 90-94% following 10 years

33
Q

What are the three techniques to evaluate dental implants

A

peri-implant probing
existence of mobility
radiographic examination

34
Q

This of an object is strongly correlated to the boundary constrains of the structure

A

resonance frequency analysis (RFA)

the higher the # the better stability

35
Q

is keratinized tissue or attached gingiva required around dental implants

A

yes, especially in partially edentulous

36
Q

What is the success rate for implants placed at grafted sites

A

about the same - stability
