define .biomaterials .- .correct .answer.materials .that .are .engineered .to .interact .with
.biological .systems .in .order .to .direct .medical .treatment
define .bio-inert .materials .- .correct .answer.engineered .biomaterials .that .don't .illicit .an
.adverse .response .from .the .human .body
define .bio-active .materials .- .correct .answer.engineered .biomaterials .that .help .facilitate
.some .kind .of .physiological .response .or .action
Dr. .Higginson .uses .what .term .in .place .of .bio-active .materials .sometimes? .- .correct
.answer.fertilizer
define .engineering .design .- .correct .answer.material .selection .governed .by .matching
.material .properties .with .requirements .of .application
when .designing .a .new .biomaterial, .what .are .the .5 .considerations .you .need .to .take .into
.account? .- .correct .answer.1. .foreign .body .reaction
2. .stress .shielding
3. .biocompatability
4. .bioactivity
5. .osteoinduction
define .stress .shielding .- .correct .answer.reduction .in .bone .density .as .the .result .of .the
.removal .of .a .typical .stress .at .that .bone, .usually .due .to .an .implant .such .as .bone .plates.
the .(more/less) .flexible .a .material, .the .(more/less) .stress .shielding .we .experience. .-
.correct .answer.more, .less
when .considering .biomaterial .designs, .what .is .meant .by .bioactivity? .- .correct
.answer.placing .a .coating .on .materials .that .are .bio-inert .to .make .the .bio-active, .in .order .to
.elicit .some .sort .of .response.
define .osteointegration .- .correct .answer.how .well .a .material .integrates .with .bone
, in .the .paper .'Biomaterials .in .Orthopaedics', .what .were .the .three .generations .of
.biomedical .materials, .and .what .was .the .point .they .stressed .about .these .generations? .-
.correct .answer.Gen .1: .bioinert .materials, .Gen .2: .bioactive .and .biodegradable .materials,
.Gen .3: .materials .designed .to .stimulate .specific .responses .at .the .molecular .level. .
The .important .considerations .is .that .these .are .not .chronological, .each .contributes .to .what
.we .know .today, .and .characteristics .from .each .generation .are .still .used.
the .first .generation .of .biomaterials .were .required .to .be ._____________ .in .order .to .reduce
.their .corrosion .and .their .release .of .ions .and .particles .after .implantation. .- .correct
.answer.as .inert .as .possible
the .second .generation .of .biomaterials .was .developed .to .interact .with .the .biological
.environment .to .enhance .____________________ .and .__________________. .- .correct
.answer.biological .response .and .tissue/surface .bonding.
a .second .goal .of .the .Generation .2 .biomaterials .was .to .give .them .the .ability .to .undergo .a
.progressive .___________ .while .new .tissue .___________. .- .correct .answer.degradation;
.regenerates .and .heals.
the .third .generation .of .biomaterials .is .designed .to .do .what? .- .correct .answer.stimulate
.specific .cellular .responses .at .the .molecular .level
stainless .steels .are .primarily .used .for ._______ .implant .devices. .- .correct
.answer.temporary
what .are .the .5 .properties .of .stainless .steels .for .biomaterials? .- .correct .answer.high
.strength, .ductility, .fatigue .performance, .corrosion .resistance, .resistance .to .pitting
what .are .the .5 .properties .of .cobalt-chromium .alloys .for .biomaterials? .- .correct
.answer.highly .resistive .to .corrosion, .resistant .to .fatigue .cracking, .relatively .ductile,
.exceptional .bio .compatibility, .high .strength.
what .is .the .reason .austenitic .stainless .steel .is .no .longer .used .for .metal-on-metal .pairs .in
.joints .such .as .the .hip? .- .correct .answer.the .wear .resistance .is .poor
Co-Cr .based .alloys .of .Stainless .Steel .have .been .associated .with .higher .degrees .of
._______ .due .to .their .strength .and .high .modulus. .- .correct .answer.stress-shielding
what .is .the .alloy .we .talked .about .under .the .stainless .steel .unit? .- .correct .answer.cobalt-
chromium .alloys
what .element .is .sometimes .put .in .cobalt-chromium .alloys .to .further .strengthen .them?
.what .is .the .downfall? .- .correct .answer.nickel, .some .people .are .allergic
