Bloomden PEEK - iyo simbi-isina imwe nzira mune yemazino tekinoroji

Kutanga kwePolyetheretherketone (PEEK)

Polyetheretherketone (PEEK) ndeyekugadzira zino rekupenda polymer zvinhu izvo zvave zvichishandiswa sebiomaterial mune orthopedics kwemakore mazhinji. Muna 1978, yakagadzirwa neboka revasayendisiti veBritish. Gare gare PEEK yakatengeswa kune maindasitiri ekushandisa. Pakazosvika makore ekuma1990, PEEK yaive yakakosha yepamusoro-inoshanda thermoplastic mumiriri kutsiva simbi inodyara zvikamu.

Applications

• PEEK Korona

Etching ne sulfuric acid inogadzira yakakasharara yakashandurwa makemikari nzvimbo inobvumira kuti ibatane zvakanyanya nehydrophobic resin composites. Zvakaonekwa kuti shear bond simba rekuisa resin composite simende yakakwira kusvika 15.3 7.2 MPa mushure mekuchengetwa mumvura pa3780 C kwe60-90 s ine sulfuric acid etching. Etching nePiranha Acid uye Kushandisa Adhesive Reagents zvakaratidzwa kuti zvinogadzira composite resin tensile bond simba rinosvika 23.4+/-9.9MPa mune yekare PEEK mienzaniso. Pakanga pasina musiyano wakakosha mukusimba kwechisungo pakati pePEEK korona uye dentin abutments uchishandisa air abrasion uye sulfuric acid etching maitiro. Zvidzidzo izvi zvinoratidza kuti PEEK inogona kushandiswa sechinhu chekuvhara pasi pemakombikisheni eresin.

• PEEK Abutment

Tichifunga kukwana biocompatibility, kudyara kuporesa abutments kunogona kuvakwa uchishandisa PEEK. Bone resorption uye zvinyoro zvinyoro kuzvimba hazvina kusiyana zvakanyanya pakati pePEEK uye titanium abutments. Uye zvakare, iyo yemuromo microflora yakasungirirwa kune PEEK abutments yaive yakafanana neabutments yakagadzirwa netitanium, zirconia, uye polymethyl methacrylate. Kubatana kwepedyo kweiyo elastic modulus yepfupa kune PEEK pamusoro inoderedza kushushikana kwekudzivirira mhedzisiro uye inosimudzira kugadzirisa kwemapfupa. Naizvozvo, PEEK inogona kuratidza kuve imwe nzira inoshanda kune titanium yekuvaka yekuisa abutments.

• PEEK mumaProstheses anobviswa

Traditional removable dentures (RDPs) ane chrome-cobalt mafuremu uye clasps akabuda senzira isingadhuri uye inofanotaurwa yekurapa yekugadziriswa kwevarwere vane zvishoma. Kuratidzwa kusingagamuchirwi kwemasimbi mabuckles, kuwanda kwehuremu hweprosthesis, mukana wekuravira kwesimbi, uye kusawirirana nesimbi zvakakonzera kuunzwa kwezvinhu zvakawanda zvethermoplastic, zvakaita senaironi uye acetal resins, mukuita kwekiriniki. Mumakore mashoma apfuura, imwe prosthetic material (PEEK) yakashandiswa zvinobudirira mundima yezvokurapa, kunyanya mune orthopaedics. Iyo yakagadziridzwa PEEK zvinhu ine 20% ceramic filler ndeye yakakwira performance polymer ine yakakwira biocompatibility, yakanaka michina zvivakwa, yakakwirira tembiricha kuramba uye kugadzikana kwemakemikari. Nekuda kweiyo elastic modulus ye4 GPa, yakatsetseka sebhonzo, ichidzikisa kushushikana kunopfuudzwa kune abutment. Pamusoro pezvo, iyo chena ruvara rwePEEK furemu inopa yakasarudzika nzira yekushongedza pane yechinyakare simbi furemu inoratidza. Mamwe mabhenefiti eiyi polymer zvinhu kubviswa kweallergic reactions uye kuravira kwesimbi, yakakwirira kupukuta mhando, yakaderera plaque affinity uye yakanaka abrasion kuramba.

• PEEK orthodontic waya

PEEK inogona kushandiswa seyakanaka orthodontic waya. Kuenzaniswa nemamwe mapolymers, akadai se polyvinylsulfone (PES) uye polyvinylidene fluoride (PVDF), PEEK orthodontic waya inopa yakakwirira orthodontic simba. Masimba akafanana e orthodontic akawanikwa achienzaniswa netitanium-molybdenum uye nickel-titanium waya.

• PEEK kudyara

Mumakore ekuma1960, intraosseous mazino anodyara ainyanya kugadzirwa nesimbi yakachena titanium uye titanium alloys. Kunyange zvazvo titanium implants inotsigirwa nehuwandu hwekuedza uye kliniki yekutsvakurudza uchapupu, kuchine mamwe matambudziko mukushandiswa kwavo kwekliniki. Imwe ndiyo inogona kukurudzira titanium. Chechipiri, kana zvichienzaniswa nenyama yemapfupa emunhu, elastic modulus yetitanium yakanyanyisa, iyo inowanzogadziriswa kana kurasikirwa kwemapfupa emapfupa. Chechitatu, simbi inodyarwa haina chiedza transmittance, iyo inokanganisa chitarisiko.

Muna 1998, kambani yeBritish Invibio yakatanga kudyara kwePEEK. Nekuuya kwekutengesa kwePEEK kudyara, kutsvagisa kwakabatana kwakawedzera zvishoma nezvishoma. PEEK nezvinhu zvayo zvakagadziridzwa zvine zvinhu zvakanaka. Dzimwe nyanzvi dzinotenda kuti PEEK implants inogona kudzivirira kuitika kwekunetseka kwekudzivirira mhedzisiro, uye inogona kutotsiva masimbi esimbi mukuvhiya kwepurasitiki, kuvhiyiwa kwekushungurudza uye mamwe minda.

Advantages

1. Biocompatibility - The biocompatibility yePEEK yakave yakaratidza, nezvidzidzo zvakawanda zvinosimbisa kuti haisi-chepfu. Kunyangwe mushure mekushandiswa muzviuru zvevarwere, PEEK inoramba iri sarudzo yakanaka kana ichienzaniswa nesimbi, izvo zvinogona kukonzera kusawirirana muvanhu vanosvika gumi neshanu muzana.

PEEK zvikamu zvinoshandiswa mumaspinal implants, trauma fixation zvishandiso, hudyu nemabvi kutsiva, uye zvimwe zvigadzirwa zvekurapa. Chero zvazvingava, hapana mubvunzo nezvekuchengetedzwa kwePEEK mumuviri.

2. Mechanical properties - PEEK ine yakanakisa simba-ku-kurema reshiyo, iyo inonyanya kukosha kune mazino anodyara nemidziyo. Kuenzaniswa nesimbi, PEEK yakareruka uye yakasununguka kune murwere. Iyi yakawedzera nyaradzo zvakare haikanganisi kusimba, sezvo PEEK ichikwanisa kumira abrasive uye compression masimba pasina kurasikirwa nekuvimbika kwayo. Iyi polymer haipindirwe nekuora uye inotora hunyoro pachiyero chidiki, saka inogona kugara kwemakore pasina kuderedzwa kwekuita.

3. Machining kugona-Mazino ari kuvimba nekombuta-anobatsira dhizaini (CAD) uye machining (CAM) kupfuura kare, uye PEEK yakakwana kune iyo. Chinhu chakakosha chemidziyo yemazuva ano yemazino ndiyo chaiyo inofanana nemuviri wemurwere, uye CAD/CAM inofanirwa kuigadzira. Izvi zvinovimbisa kuti mudziyo uchazorora zvakanaka, ushande zvakanaka uye ushandiswe kwenguva yakareba sezvinobvira.

Kana PEEK ikagadzirwa kune zvakatemwa nemugadziri, inochengeta zvivakwa zvayo mushure mekugaya. Uku kugadzikana kwakawedzera kunobvumira kushanduka kukuru panguva yekugadzira chikamu uye kunoita kuti zvive nyore kune vanachiremba vemazino kugadzirira varwere vavo michina yetsika.

PEEK iri nyore kuenderana neCAD/CAM nzira zvakare zvinoreva kuti inogona kugadziriswa nekukurumidza uye nguva dzose. Muchidimbu, PEEK zvishandiso zvinogona kugadzirwa zvakavimbika uye nekukurumidza.

4. Flexibility - Iyi yemhando yepamusoro yepolymer inogara asi haina kuomarara. Kana isina kuzadzwa, inopa modulus yakafanana necortical bone, ichiita PEEK yakasimba, inoshanduka mazino zvinhu. Nekuwedzera kwayo kuchinjika, PEEK inonzwa yakasikwa mumuromo uye inoramba yakanyungudika kunyangwe mushure memakore ekuruma nekutsenga. Mazino emazino anofanirwa kuchengetedza chimiro chawo achiri pasi pekumanikidzwa, uye PEEK ndeimwe yeakanakisa mapolymers eizvi.

5. Radiolucent - The bone-like modulus uye radiolucency yePEEK zvinhu zviviri zvakatanga kukwezva kutarisa kwevanotsvakurudza vezvokurapa kuPEEK, uye inoramba iri imwe yezvinhu zvakakosha zvepolymer. Mumakore achangopfuura, tsvakiridzo yePEEK mazino anodyarwa yakaratidza kuti zvinhu zvacho zvine mukana wakakura mundima iyi.

Iyo radiolucency yePEEK chinhu chakakosha kana zvinhu zvacho zvichishandiswa mune chero nzira yekuisa. Kana ichinge yasimwa, iyo polymer haizokanganisa nekuona X-ray, CT kana MRI scans. Sezvo X-rays yakakosha pakuongororwa kwemazino, kusajeka kwePEEK pamufananidzo kuchaita kuti vanachiremba vemazino vakwanise kuita basa ravo rekutarisa hutano hwemurwere. Ipo PEEK's yepamusoro radiolucency ingaonekwa sechipingaidzo, iyo polima inogona kuvandudzwa nezvinowedzerwa zvakaita sebarium sulfate kugadzira musiyano uri nani.

6. Aesthetics - Kungofanana nePEEK inogona kugadzirwa nyore nyore kuva maumbirwo etsika, inogona kuva ruvara rwakanyatsoenderana nemurwere. Kusiyana neizvi, simbi kazhinji hazvibviri kuvanza mumuromo, izvo zvinonetsa varwere.

PEEK inhengo yemazino inosanganiswa nyore mumuromo nekuti ruvara rwayo runogona kugadziridzwa panguva yekugadziriswa. Kunyangwe mazino emazino akazara anogona kugadzirwa zvakasununguka, kuve nechokwadi kuti varwere vanogona kutaura, kunyemwerera uye kudya nechivimbo.

7. Neutral kuravira - Rimwe dambudziko nemidziyo yesimbi ndeyekuti inopa kuravira kwesimbi kune varwere vazhinji. Haisi nyaya yehutano, asi inogara ichishungurudza varwere vasingade kuyeuchidzwa kuti vane mazino emazino kana mafuremu.
