Good survival rate (85% 10 years)
28
When are subperiosteal implants indicated?
indicated for atrophic edentulous mandible
29
What was an issue with subperiosteal implants:
bone resorption over time lead to mobility, infection, and loss

35
Why are transosteal implants not widely used?
requires invasive surgery usually in hospital setting (external incision/approach)
36
A transosteal implant is excellent for ____ where root form implants would weaken the jaw.

41
When are transmandibular implants indicated?
used for severe atrophic mandible (less than 10 mm)
42
What material is used for dtransmandibular implants?
gold alloy (NOT titanium)
43
Transmandibular implants require a complex process, however they are ___ due to the design of screws and degree of integration
reversible
44
What type of implant is seen in the following images?
transmandibular
45
Type of implants that eliminates the need for significant bone grafting, ridge augmentation or vestibuloplasty and allows facial muscles to be reattached to improve facial profile:
Transmandibular
46
The following image shows examples of:
endosteal implants
47
The following image shows what type of implant?

48
List three examples of endosteal implant types:
1. blade 2. cylinder 3. screw
49
____ implants are made of titanium and were introduced in 1969 for the possibility of restoring partially edentulous mandibles.
Blade
50
Describe the survival rate for a blade implant:
good not great
51
Type of implant used mostly in the 80s:
blade implant
52
Describe the failures of blade implants:
largely due to the heat production during the implant site preparation and immediate loading
53
The following image shows what type of implant?
blade implant
54
The following image shows what type of implant?
blade implant
55
Considered the modern day implant:

greater than 90% with the most recent ones at 98%
57
What materials comprise root form implants?
titanium or an allow of titanium-aluminum-vanadium metals
58
Root form implants are indicated for:
partially & completely edentulous patients both in the maxillary and mandibular arches

Became the standard with research of Branemark in 1970 based on the concept of osseointegration:
Root form implants
60
Describe the surface of root form implants:
may be machined or roughed
61

What term was introduced by branemark?
osseointegration
64
A direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant:
Osseointegraton
65
What material is not recognized by the body as a foreign object?
titanium
66
Because titanium is not recognized as a foreign object by the body there is less:
host rejection
67
Because titanium is not recognized as a foreign object by the body there is less host rejection, this allows for:
integration into the surrounding hard tissue
68
Teeth are susceptible to caries & periodontal disease, while implants are susceptible to:
1. peri-implantitis (bone) 2. peri-mucositis (soft-tissue)
69
Peri-implantitis affects the:
bone
70
Peri-mucositis affects the:
soft-tissue
71
What determines whether an implant design is considered one-piece or two-piece?
depending on if the prosthesis abutment is part of the implant or a separate piece
72
What determines whether the implant is tissue level or bone level?
dependent on if the implant is fully embedded into the surrounding bone or presents in the transmucosal portion
73
What determines whether an implant is external hex or internal hex?
distinguished by whether the implant area connecting the implant to the prosthetic components protrudes form the implant or is internal to it
74
What is the predictability of a single implant fixture survival rate?
94-98%
75
55-60% of implant failures occur:
prior to placement of the restoration
76
40-45% of implant failures occur:
after the restoration placement
77
