What is a dental implant?

A prosthetic device or alloplastic material implanted into the oral tissues beneath the mucosal and/or periosteal layer, and/or within the bone to provide retention and support for a fixed or removable dental prosthesis

What is a transosteal implant made of?

Study These Flashcards

titanium metal

What is the 15 year success rate of a transosteal implant?

91%

When are transosteal implants indicated?

Only indicated for the edentulous mandible - Excellent for the atrophic mandible where root form implants would weaken the jaw

What type of denture is used with a transosteal implant?

Denture is tissue supported

Why are transosteal implants not widely used?

- Requires one surgery usually in the hospital. - External incision / approach - Complex surgical procedure therefore not widelyused.

Where can you put a transosteal implant?

Restricted to the anterior mandible.

What is the success rate of a transmandibular implant?

97%

What type of denture is used with a transmandibular implant?

implant supported denture

What is a transmandibular implant made of?

Gold alloy

What makes a transmandibular implant reversible?

can be removed due to design of screws and degree of integration, but not easy process

When are transmandibular implants used?

Used for severe atrophic mandibles <10mm

What does a transmandibular implant allow for?

■Allows facial muscles to be reattached to improve facialprofile ■One stage, extra-oral approach (submental) ■Eliminates ridge augmentation or vestibuloplasty

What are the three types of endosteal implants?

blade, cylinder, screw

What are the characteristics of a blade endosteal implant?

■ Titanium metal ■One stage/best for partially edentulous mandibles ■Most widely used until 1980

What is the success rate (5 years) of the blade endosteal implant?

75%

What caused early failures of the blade endosteal implant?

heat at preparation and immediate loading

What are the drawbacks of a blade endosteal implant?

Difficult to prepare a precision slot and if it fails, a large section of bone is involved

What is the success rate of a root form endosteal implant?

greater than 90%

When are root form endosteal implants indicated?

partially and fully edentulous cases/any area of the mouth (versatility)

What are the uses of root form endosteal implants?

overdenture, hybrid, crown and bridge, ortho anchorage

What are the characteristics of a root form implant?

■Titanium or an alloy of titanium-aluminum-vanadium metal ■1 or 2 stage approach ■ In office procedure ■Screws/Cylinders ■Machined or rough (to increase surface area for integration)

Who's research made root form implants the standard?

Per-Ingvar Brånemark (the daddy of implant dentistry)

What type of implant can you use the posterior maxilla is atrophic?

Super Implants: Zygomatic & Pterygoid

What is osseointegration?

a direct structural and functional connection between ordered, living bone and the surface of a load-carrying implant

Why is titanium used for implants?

■ Not recognized as a foreign object by the body ■ Less host rejection than other metals/alloys ■Medicine also recognized utilization in joint replacements and heart valves

What are the differences in disease processes between teeth and implants?

Teeth: * Caries * Periodontaldisease Implants: * Peri-implantitis (bone) * Peri-mucositis(soft-tissue)

What are the different types of implant designs?

- one piece vs two piece - tissue level vs bone level - external hex vs internal hex

Predictability of single implant fixture survival is in the _______% range

94-98%

_____% of implant failures occur prior to the placement of the restoration

55-60%

_____% of implant failures occur after the restoration placement

40-45%

What % of implant failures occured in the 1st, 2nd, and 3rd year?

* 57% of the failures occurred in 1st year * 34% of the failures occurred in the 2nd year * 9% of the failures occurred in the 3rd year * 0%after?

How much bone loss during the 1st year of implant?

1 mm average

How much bone loss during each year after the first year of implant?

0.1 mm average

__mm of soft-tissue recession can generally be expected during the first year of an implant

1mm

Most soft tissue recession occurs within the first ___ months following abutment connection surgery
