history of implantatolgy
beginning -
1800-1978-
1978 - present
beginning - 1800 - non scientific period
1800-1978 =trial and error
1978 - present = osseointegration
mplantatolgy
beginning -
1800
egyptian tooth replacement
gold and wood susbtituted as well as animal teeth were used as replacemetn teeth in 400 BC
roman specied - 100-200 AS
honduras 600 AD
1800-1978-
trial and error periord
endodontic implants
sub-periosteal
blade implants
5-6 years = 50-60% survival rates
staple implants
- 5 and 7 pins
osseointegration definition
direct bone anchorage to an implant body which will provide a foundation to support a prothesis , it is able to transmi occlusal forces directly to the bone
starts from bone to implant
- contact osteogenesis – osteoblast gets caught in fibrin mesh - slowly bone matures
classification of dentla implants
- position
- constituent material
- physical form
- surface coating
- coronal design
- surgical installation
position breakddown
subperiosteal
transosteal
endosseous
subperiosteal
- everything about it
2 stage
- open and make impression of mandible - suture
- lab makes supperperiosteal implant - reopen and place
- can make denture and immediate load
take the form of a framework - resting on the srface of the jawbone
- not integrated
more common on lower and more common to be bilateral
more common for completely edentulous patients
bone resorption present - recommended
can support overdenture appliance
made from VITALLIUM and can be coated with hydroxylapatite
transosteal implants
everything about it
exclusively lower
inserted through jaw bone from underneath
vitallium and gold
under GA and in hospital
9-11 mm of bone height to remain
can be a mandibular staple or transmandibular implant
Brief description of endosseous implants
most commonly used implants
they are usually multiple, separate units that are subclassified according to their physical shape
coated implants?
tricalcium phosphate
hydroxyalapatite
materials used?
metals
- Majority of them – titanium alloy
ceramics
polymers
treated implants?
acid etched
sand blasted
laser etched
coronal design break down
external hex
internal hex
internal bevel, machined interlocked, morse taper
butt joint and flat top
polymer butt
external spline, internal spline
two stages
placement of implant and submerging it under the gingiva = which requires a second surgery to uncover
one stage implant
without submerging it under gingiva
immediate delay
placing of an imlant a few weeks after extraction
waiting for soft tissue to resolve
immediate placement
extraction of a tooth and the placement of an implant in the etraction site at the same time
immediate loading
the placing of a functinoal prosthesis shortly after implant plaement
immediate prosthesis
placing of a nonfunctinoal prosthesis shortly after implant placement
NOT FUNCTINAL
standards of success proposed by albrektsson, zarb and worthingoton, and eriksson in 1986?
- that an individual unattched implant is immobile when tested clinically
- that radiograph does NOT demenonstrate any evidence of peri-implant readiolucency
- that vertical bone loss be less than .2mm annually following the implants first year of service
- absence of peristent and or irreversible signs and symptoms such as pain, infections, neuropathies, paresthesia, or violation of mandibular canal
- that in the conext of #4 - a success rate of 85% at the end of a 5 year observation period and 80% at the end of a ten year period be a minimum criterion for success
8 steps to implants (on mandible)
- full mouth x ray and pano
- impression for surgical template
- CT scan
- tx planning
- implant surgery
4 MONTHS - uncovering
4 WEEKS - fincal impression for prosthesis
2-4 MONTHS - case complete
Limiting factor in posterior maxilla?
anterior maxilla?
sinus = posteiro
floor of nose = anterior
how far from nerve must be
3 mm
+ need 1 mm around implant of bone (he prefers 2)
what type of anesthetic and why
infiltration
b/c if block – and do get close to nerve they wouldnt know weither
