Good survival rate (85% ten years)
28
When are subperiosteal implants indicated?
Indicated for atrophic edentulous mandible
29
What was an issue with subperiosteal implants?
Bone resorption over time leads to mobility, infection & loss
30
What type of implant is seen in the following images?

31
Implants introduced in 1968 and made of titanium:
Transosteal implants
32
Describe the survival rate of transosteal implants:
Good success rate (91% at 15 years)
33
When are transosteal implants indicated?
Only indicated for the edentulous mandible
34
The denture for transosteal implants is:
tissue supported
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
atrophic mandible
37
Transosteal implants are restricted to:
the anterior mandible
38
What type of implant is seen in the following image?
transosteal implant
39
TMI:

40
Transmandibular implants are restored with:
implant supported denture
41
When are transmandibular implants indicated?
Used for severe atrophic mandibles (less than 10mm)
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 the screws and degree of integration
reversible
44
What type of implant is seen in the following images?
transmandibular implants
45
Type of implant that eliminates the need for significant bone grading, ridge augmentation or vestibuloplasty and allows facial muscles to be reattached to improve facial profile:
transmandibular implants
46
The following image shows examples of:
endosteal implants
47
The following image shows what type of implant?
transmandibular implants
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 implant
50
Describe the survival rate of blade implants:
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 implants?
Blade implants
54
The following image shows what type of implants?
Blade implants
55
The following image shows what type of implants?

greater than 90% with the most recent ones being 98%
58
What materials comprise root form implants?
titanium or an alloy of titanium-aluminum-vanadium metal(s)
59
Root form implants are indicated for:

61
Describe the surface of a root form implant:
May be machined or roughed

64
What term was introduced by Branemark?
Osseointegration
65
A direct structural and functional connection between ordered, living bone and the surface of a load-carrying unit:
Osseointegration
66
What material is not recognized by bone/body as a foreign object?
titanium
67
Because titanium is not recognized as a foreign object by the body there is less:
host rejection
68
Because titanium is not recognized as a foreign object by the body there is less likely to reject, this allows for:
integration into the surrounding hard tissue
69
Teeth are susceptible to caries and periodontal disease, while implants are susceptible to:
1. peri-implantitis (bone) 2. peri-mucositis (soft tissue)
70
Peri-implantitis affects the:
bone
71
Peri-mucositis affects the:
soft tissue
72
What determines whether an implant design is considered one-piece or two-piece:
depends on if the prosthesis abutment is part of the implant or a separate piece
73
What determines whether the implant is tissue level or bone level?
depends on if the implant is fully embedded into the surrounding bone or presents in the transmucosal portion
74
What distinguishes whether an implant is external hex or internal hex?
Distinguished by whether the implant area connecting the implant to the prosthetic components protrudes from the implants or is internal to it
75
What is the predictability of a single implant fixture survival rate:
94-98%
76
55-60% of implant failures occur:
prior to the placement of the restoration
77
40-45% of implant failures occur:
after the restoration placement
78
____% of failures occur in the 1st year ____% of failures occur in the 2nd year ____% of failure occurred in the 3rd year
57% 34% 9%
79
