Why might biointegration be preferable to osseointegration?

• With biointegration more bone is

  deposited.

• With biointegration bone contact

  occurs more rapidly.

• With biointegration less connective tissue is deposited.

• With biointegration the bone-implant interface is stronger.

• With biointegration higher drill

  speeds can be used.

What term describes an implant that is within bone and encapsulated by connective tissue?

• Fibro-osseous integration

• Biointegration

• Osseointegration

• Bone-implant interface

• Implant fixture

Over the long term the success of an

implant depends on

• the epithelium tissue interface

• the amount of osseointegration

• the ability of the implant to integrate with alveolar bone

• the transmucosal seal

• all of the above

For rapid osseointegration to occur, what type of material should be used?

• Vitreous carbon

• Acrylates

• Titanium

• Polymer

• Nonprecious metal

The width of supracrestal connective tissue around the neck of a healthy implant

• May vary based on initial mucosal thickness

• Is approximately 1-1.5 µm

• Is approximately 1-1.5 cm

• May vary with time

• A and B

If vitreous carbon implants are used, what percent can be expected to fail?

• 40%

• 35%

• 60%

• 50%

• This information is not provided in the passage.

After 1 year what difference can be noted between a plasma-sprayed titanium implant and an HA-coated implant?

• Little to no difference is apparent.

• The plasma-sprayed implant has a six- fold increase in osseointegration.

• The HA-coated implant has a higher percentage of bone contact.

• The HA-coated implant has less bone contact.

• The plasma-sprayed implant has less bone contact.

An implant coated with bioglass will result in

• osseointegration

• fibro-osseous integration

• reduced bone deposition

• biointegration

• C and D

Alveolar bone is made up of

• fibrous connective tissue

• cancellous bone

• cortical bone

• junctional epithelium

• B and C

What reason/reasons is/are given to explain why fibro-osseous integration occurs?

• Premature loading of the implant

• Heat-induced bone necrosis

• Lack of primary stability

• A and B

• All of the above
