Zvishandiso zveCeramic zveZuva Rimwe Chete: Nei Maitiro Akawanda Ari Kufambira Padivi Pechigaro CAD/CAM

Hazvisi zvekukurumidzisa kugadzirisa zvinhu, asi kuronga patsva kuti chipatara chinopa sei munhu wese zino rimwe chete.

Murwere anogara pasi. Kuzadzwa kukuru kwemazino pamuromo wavo kwakundikana zvakare. Chavanoda kuziva chiri nyore: "Tinogona kuchengetedza mazino akawanda echisikigo here? Uye izvi zvinogona kuitwa nhasi here?"

Mukushanda kwetsika, mhinduro inowanzova kwete. Kuonekwa, kugadziriswa kwenguva pfupi, uye kusangana kechipiri mavhiki maviri gare gare ndizvo zvinodiwa. Asi ne intraoral scanner, CAD design, uye chairside milling machine, maitiro ese - kugadzirira, scan, dhizaini, chigayo, uye cementation - zvinogona kuitika kamwe chete. Murwere anobuda zuva rimwe chete nekugadziriswa kweceramic zvachose.

Heino maitiro chaiwo anoita padivi nepadivi:

Nemuchina wekugaya uri pachigaro, dambudziko remavhiki maviri risingafadzi rine kupora kwenguva pfupi rinobviswa zvachose. Murwere haafanire kurarama nedambudziko renguva pfupi rinogona kupera chero nguva — uye haafanire kudzoka kuzoshanya kechipiri.

Izvi hazvisi zvekungoronga nguva chete. Zvinoshandura ruzivo rwemurwere, zvinoshandura maitiro anoita chiremba wemazino kudzora kunaka kwekugadziriswa kwemurwere, uye zvinochinja patsva maitiro anoita kambani kuronga bhizinesi rayo rekugadzirisa.

Kana humbowo hwenguva refu hwekiriniki, kushanduka kwezvinhu, uye hupfumi hwemaitiro zvese zvikanangana nedivi rimwe chete, zvigadzirwa zveceramic zvezuva rimwe chete zvinorega kuva tekinoroji "yakanaka kuva nayo" uye zvinova kugona kwekiriniki kwakakodzera kuvakwa.

Kubva Pakumirira Kwemavhiki maviri kusvika Pachigaro chezuva rimwe chete: Mashandiro Anoita Basa Repadivi Pechigaro

Kugadziriswa kwechigaro pazuva rimwe chete kunovhiringidza mashandiro ebasa aimbove akakamurwa munzvimbo dzakasiyana-siyana, kupihwa mabasa akawanda, uye kugadzwa kwemabasa akawanda muzuva rimwe chete:

Kugadzirira mazino → Kuzviparadzanisa uye kutarisa margin → Intraoral scan → CAD design → CAM milling → Crystallization/sintering kana surface treatment sezvinodiwa → Edza → Cementation uye occlusal verification.

Murwere haadzokeri kushanyazve uye haazosangani nepfungwa dzisina chokwadi uye haadzorerwe kwenguva pfupi. Chiremba wemazino anoramba achidzora mipendero, kubatana kwepedyo, contour, uye kuvharika kwemuviri wake apo murwere achiri pachigaro. Kana chimwe chinhu chichida kugadziriswa, vanogona kudzokera kudanho rekugadzira kana kugadzira nekukasika.

Saka kukosha kwe "zuva rimwe chete" hakusi kukurumidza chete. Kunoshandura kudzorerwa kubva pakupatsanurwa kwezvikamu kuita denderedzwa rakavharwa iro chiremba wemazino anotonga kubva pakutanga kusvika pakupera.

Zvishongedzo zveCeramic neOnlays: Zvinoratidzwa Nehumbowo Hwenguva Refu

Kuisa zino mumuromo inzira yekudzoreredza zino isina kunanga yakagadzirwa kunze kwemuromo uye yakabatanidzwa mumazino. Kana zino rakakanganisika richida dziviriro, kudzoreredza kunosvika pakuisa zino mumusoro kana pamusoro. Zvichienzaniswa nekorona yakazara, nzira idzi dzekufukidza zino zvishoma dzinochengetedza chimiro chemazino chine hutano kana mamiriro ezvinhu achibvumira.

Dzinozadza musiyano mukuru uripo pakati pekugadzirisa zvakananga uye makorona akazara: dambudziko racho rakakura zvekuti kuzadza kwakananga hakugone kudzora chimiro, kubatana, kana kushanda kwaro, asi chimiro chezino chasara chakakodzera kuchengetedzwa uye hachifanirwe kuve nekorona yakazara.

Ruzivo rwenguva refu runotsigira nzira iyi. ongororo yakarongeka uye meta-analysis ye resin uye ceramic inlay, onlay, uye overlay survival Zvakaitwa pakuongorora zvinhu zvinosvika zviuru zvitanhatu (6,000) zvakawana kuti kugadziriswa kwegirazi-ceramic uye feldspathic porcelain kwakawana mwero wekurarama kwemakore mashanu we92–95% uye kurarama kwemakore gumi kweinenge 91%. kuongorora kwakawanda kweCAD/CAM maprostheses akasimbiswa anotsigirwa nezino chete inofungidzira kuti huwandu hwevanhu vanorarama kwemakore matatu, mashanu, uye gumi hunosvika 94.66%, 91.1%, uye 82.2% zvichiteerana.

Zvidzidzo izvi hazvivimbise kuti kugadziridzwa kwese kuchagara kwemakore gumi. Asi zvinopa chikonzero chakajeka: kana zviratidzo zvakakodzera uye nzira yekurapa yakanaka, machira eCAD/CAM ceramic inlays ari padivi pechigaro anopa mhedzisiro inofungidzirwa yenguva yepakati kusvika kure. Kukurumidza hazvirevi kuti inogara kwenguva pfupi.

Kugamuchirwa kweCAD/CAM padivi pechigaro pasi rose

Ruzivo rwekutorwa kwevana runotaura nyaya yakafanana, kunyangwe nzira dzekuongorora netsananguro dzichisiyana nenyika:

Kana tichifunga nezvekudyara mari, chidzidzo chiri nyore: iyi haisi tekinoroji yekuyedza yakamirira kusimbiswa. Mienzaniso yekiriniki neyekutengeserana iripo kare, mumakondinendi akawanda uye masisitimu ehutano.

Zvinhu Zvinogadziriswa Zvekugadzirisa Ceramic Yezuva Rimwe Chete

Vagadziri pasi rose vakagadzira mhando dzakasiyana dzemabhuroko anogona kugadzirwa zvakanangana nechekugadzika uye murabhoritari yeCAD/CAM. Kuabatanidza nesainzi yezvinhu zvinobatsira kujekesa kuti ndeapi anofanira kushandiswa nemuchina wemazuva ano wekugaya:

Vagadziri vakasiyana vanoshandisa mazita akasiyana — "hybrid ceramic," "composite ceramic," "polymer ceramic" — asi mafambiro acho akafanana: zvinhu zvakagadzirwa kuti zvigadzirwe nedhijitari uye nekukurumidza kugayiwa, nekugadzirwa kwakareruka mushure mekushandiswa kunotsigira kutumirwa kwezuva rimwe chete.

Mhinduro dzeGlobalDentex dzekugaya nekugadzira sintering dzakagadzirwa kuti dzigadzirise zvese zviri pamusoro apa. Muchina wekugaya wakanyorova uye wakaoma weDN-H5Z une mativi mashanu uye DN-W4Z Pro inoshanda zvakanyanya mugirazi-ceramic mill gadzira magirazi eceramics, lithium disilicate, zvinhu zvakasanganiswa, nezvimwewo. Kune maworkflows akavakirwa pazirconia, Muchina wekugaya wakaoma weDN-D5Z une axis 5 vaviri pamwe chete ne Q7 choto chinokurumidza uye chinononoka kupisa , izvo zvinopedzisa kutenderera kwakazara kwekupisa mumaminitsi makumi matanhatu chete. Izvi zvinoreva kuti chero nzira ipi zvayo yekurapa yaunosarudza, michina yako haizoganhuriri sarudzo dzako dzezvinhu.

Nzvimbo shanu dzekuongorora dzekurapa dzinofungidzirwa kuti dzichagadziriswa pazuva rimwe chete

Midziyo inovandudza kushanda zvakanaka, asi haibudisi mhedzisiro chaiyo yega. Kuti ma inlay e ceramic ezuva rimwe chete ave kugona kwakavimbika, nzvimbo shanu dzekutarisa dzinofanira kupasiswa:

1. Kusarudza Nyaya. Ongorora mamiriro emazino emukati medumbu, hutano hwemazino, njodzi yekuonda kwemazino, uye kana chimiro chemazino asara chakakodzera kufukidzwa zvishoma. Hazvisi zvese zvinokanganisa zvikuru zvinofanira kuitwa pachigaro.

2. Kugadzirira mazino. Siya nzvimbo yakakwana yezvinhu zvinogadzirisa mazino. Sarudza kana zvidimbu zvakakanganisika zvichifanira kuvharwa kana kuchengetedzwa. Gwaro rekushandisa: kuderedza occlusal ye 1.5 mm ye lithium disilicate inlays; 2.0 mm pakufukidza cusp ne onlay. Kusakwana kwe ceramic cruise pamusoro pe occlusal kunoramba kuri chimwe chezvikonzero zvinowanzo kukonzera kutadza kudzoreredzwa kwemazino.

3. Dhizaini yedhijitari. Software inogona kuratidza ukobvu, muganho, kusangana, uye matambudziko ekuvharika — asi ma parameter akajairika haatsivi kutonga kwekiriniki. Chiremba wemazino anofanira kusimbisa ma parameter ese zvichienderana nenyaya yega yega.

4. Simende uye Kuisa Ziso Pacharo. Zino, chibato chekubatanidza, uye kugadziriswa zvinogovana mutoro wekushanda. Kuisa rabha padhamu ndiyo nzira yakanakisisa. Maitiro ekugadzirisa pamusoro anofanira kuenderana nechinhu chacho - hydrofluoric acid etching uye silane yegirazi ceramics; maitiro ekubatanidza anonamatira emabhuroko ane resin.

5. Kuongororwa kweOcclusal. Kugadzika nzvimbo yekugadziriswa hakusiko kupedzisa. Kupindirana, kupindirana kwe excursive, uye mavector esimba asina kunaka zvinofanirwa kuzivikanwa uye kugadziriswa murwere asati abva pachigaro. Shandisa bepa rinotsanangura uye simbisa hukama hwepakati uye mafambiro e excursive.

Chikwata chine ruzivo pachigaro hachimanikidze kuti nyaya imwe neimwe ipedzwe pazuva rimwe chete. Vanoziva nguva yekuenderera mberi, nguva yekugaya zvakare, uye nguva yekunonoka. Kufamba kwebasa kunochinja mafambiro ekugadzira, kwete mwero wekurapa.

Kuvaka Protocol yeCAD/CAM yeChairside Repeatable

Kubudirira kwemakwikwi kubva mumidziyo yeceramic yezuva rimwe chete hakuzove kwekambani yekutanga kutenga scanner nechigayo. Kuchava kwekambani inoshandura kusarudzwa kwenyaya, nzira yekurapa, uye kubatana kwechikwata kuita sisitimu inodzokororwa.

Matanho matatu ekusvika ikoko:

Danho 1: Gadzira nzvimbo yekupinda nyaya. Tanga nekuisa zvinhu zviri kumashure zvakananga uye kuisa zvinhu zviri kumashure uko kuzviparadzanisa kunogona kudzorwa uye njodzi yekuvharika iri shoma. Tsanangura nzira dzakajeka dzezvinopinda mubasa repadivi pechigaro uye zvinotumirwa kurabhoritari.

Danho rechipiri: Gadzira SOP yakakwana. Nyora mitemo yekugadzirira, magadzirirwo ekuongorora, magadzirirwo ekugadzira, kusarudzwa kwezvinhu, kushandiswa kwemushonga mushure mekugayiwa, kutevedzana kwecementation, uye kusimbiswa kwe occlusal. Ita kuti ive cheki yechikwata, kwete tsika yachiremba mumwe chete.

Danho rechitatu: Wedzera kuongorora nyaya. Tevedzera mhando ye margin, proximal contacts, magadzirirwo e milling, mhedzisiro ye cementation, uye tevera. Gadzirisa nzira yekubudirira kutanga, wozoenderera mberi zvishoma nezvishoma kune nyaya dzakaoma.

Izvi zvaitwa, CAD/CAM iri padivi pechigaro inorega kuva muchina unounganidza guruva mukambani uye inova basa rekugadzirisa rinogona kuitwa nekambani yako nguva dzose.

Nyaya Yekudzidza: Kugadziriswa Kwezuva Rimwe Chete Kwava Kugara

Humbowo hwekiriniki hwatove hwakapararira mumakondinendi akawanda uye masisitimu ehutano. Zvidzidzo zvenguva refu zvinosimbisa mhedzisiro inofungidzirwa mune zviratidzo zvakakodzera. Vagadziri vezvinhu vari kuramba vachiwedzera zvigadzirwa zvavo. Nzira yacho yakajeka.

Kune vanachiremba vemazino, mubvunzo hausisiri wekuti "tinofanira here kufunga nezve CAD/CAM ceramic inlays dziri padivi pechigaro." Ndewekuti: Ndezvipi zviitiko zvauchatanga nazvo? Ndezvipi zviyero zvekiriniki zvauchaisa? Uye zvinotora nguva yakareba sei kuti izvi zviite kugona kwakasimba uye kunodzokororwa?

Maitiro anovaka kugona uku kare ndiwo achava ekutanga kupa modhi yekupa rubatsiro iyo inotarisa panguva imwe chete ruzivo rwemurwere, kuvhiyiwa kwemazino kusingapindi zvakanyanya, uye kushanda zvakanaka kwemaitiro.
