Korona-rakaumbwa simbi: mapikicha, ongororo, kugadzwa. Production korona simbi kuti mazino

Metal nekorona pamusoro mazino vachiri dzakakurumbira, sezvo hapana asi njodzi uye vakasimba mune prosthetics havana tega. zvigadzirwa kwakadaro vaibva kare madzitateguru edu, uye vachiri kuramba tichishumira vanhu mukurumari wavo. Kunyange zvazvo fomu iri nekorona haisi chinonyanya kukwezva, asi mutengo uye unhu anoenderana chokwadi.

Chiiko ichi

Crown-kuumbwa munhu esimbi nyaya yakaitwa akasiyana alloys ose titanium simbi hromokobaltovogo, nickel-chromium, uye magadzirirwo kwaro kuumbwa chose. The dzinonyanya kushanda nzvimbo dzakasiyana-siyana ichi korona - dentures mhando kutsenga kwemeno. Izvi imhaka yavo murombo aesthetic zvinoriumba.

Crown (simbi) anonzi nyaya zvakarurama-kuumbwa izvo kunyange zvakasiyana esimbi ruvara, asi chaizvo zvakasimba agere pamuromo. nekorona kwakadaro - chisarudzo chakanakisisa kuti mazino-refu.

Zvakanakira chikwata-chakakandirwa zvigadzirwa

zvinhu kwakadaro ane nhamba zvakanaka, kureva:

1. Zvakasimba yakabatana zino mamiriro.
2. Ane kuchengeteka (mazino musaputsa uye regai mukanamatira).
3. Siyana dzinongoitika anatomical chimiro.
4. A mutengo duku zvichienzaniswa nedzimwe vezera.
5. Hazvina kudzima anorwisana mazino.
6. Zvinoshamisa Tinoenderera mberi kutsenga unongotaura.

Zvikonzero yokugadza

Nyanzvi angarayira kuisa korona simbi chete mune zvimwe zviitiko:

• akaparadza vaya meno basa kutsenga;
• Chikamu shaya vanoverengeka zvikuru Worn;
• zino ari kutambudzwa wakaremara kana kukuvadzwa;
• mazino vari anodyara.

Kuisa chigadzirwa zvakadaro, unofanira kushoma vaviri nguva kudzoka wemazino-orthopedist. Chokutanga, chiremba anoziva dzaiita zvokutaurwa radiographs shaya ipapo kutanga mazino kurapa pamusoro caries, izvo iiswe kubva resimbi korona. Kubva nzvimbo vakaronga pakona kana gadziriro, akabvisa tsinga.

Crown Metal: mhando

Kazhinji, kana murwere vanokumbira rubatsiro kuna chiremba wemazino kuisa korona zvesimbi, iye akapa mbiri zvokusarudza, zvichienderana nzira inoshandiswa:

1. Diecast chigadzirwa. It rinobudiswa pana anokosha Unobudisa kuburikidza kugocha mu sechoto. korona iyi kunoratidzwa makobvu masvingo, izvo zvakanaka inokanganisa upenyu basa. Wakaitwa kubva nechimwe (chromium alloys, nickel, simbi) uye anokudzwa simbi (Platinum, palladium, ndarama, sirivha) simbi. Nekuti simbi coloring zvigadzirwa chete prosthetic mazino lateral zvakavanzika panguva kukurukurirana. Vari optimally wakanyatsokodzera nokuda prosthetic posterior mazino nokuti angakudzivisai wandei zvinorema.
2. Ndokutsika korona kwese ruoko, iyo kukwenenzverwa chaiwo muchina kupa chigadzirwa zvandinenge chimiro.

Modelling vachikandira korona

chigadzirwa kwakadaro sechinhu akavimbika prosthesis uye yakaiswa kubva cobalt Chrome chiwanikwa. Crown (simbi), akakanda simbi ane zvazvisingarambiki ukuru - haina solder majoini, uye izvi zvinoita kuti zvikuru dzakasimba. Zvinonyatsozivikanwa wakafukidzwa grinded zino, tisingaregi musanganiswa yokubudisa samende uye kuderedza ndingangokuvara rakapinza pasi zvokudya zvake. uchishandisa nguva - makore 15-20. Modelling chakakandirwa korona rinokwana pakawanda:

• kubudikidza jekiseni of prosthesis;
• zino gadziriro (kubviswa 0.2 kusvika 0,6 mm tishu);
• kugadzirwa wakisi chivharo vaisona kuburikidza;
• kushongedzwa, wakafanira ndiko, pakuonekwa chicherwa pamusoro;
• Snapshots, kusanganisira anoshorana uye pedyo mazino.

Mimwe nyaya dzakadaro

Panguva ino, muna hofisi chiremba wemazino-orthopedist vashanda-kukanda simbi korona (inofambiswa pamusoro pavo kubva ruzhinji varwere vanogona kunzwa zvakanaka chete) pakubhadhara akawanda:

1. Uncoated - nyore zvigadzirwa simbi ruvara.
2. With sputtering. Kana murwere hakukodzeri ichi "runako,", nechido chake korona zvinogona kuitwa spraying, vachitevedzera goridhe.
3. Coated. Kukurukurwa zvikuru nemachira zvinofadza chigadzirwa, mudungwe pamwe Ceramics. divi ravo pamberi akafuka zvedongo lining. Zvisinei, tinofanira kungwarira zvikuru kana kudya, nokuti Ceramics anogona kuveura.
4. Vasanganiswa. Kana ichi prosthetic korona chikamu wakafukidzwa Ceramics, uye vamwe kuti zvakavigwa kana kunyemwerera vanonyepera pasina cladding.

ndokutsika korona

Prostheses anogadzirwa kubva fekitari anoshongwa, iyo kupa zvakakodzera chimiro. Products muri matete anoshongwa, saka hapana chikonzero vakawanda mazino kuburikidza kukuya munyama. Korona (simbi) yakaiswa kana pasina kuparadzwa midzi, uye akaramba 1/3 zino. Nokuti ayo kugadzirwa anoshandiswa goridhe kana Stainless simbi.

Kudekara pakusika rinotsanangurwa kwete chete mutengo pasi, uyewo chiduku yakararama mashoko. Gold ndokutsika korona dzakagadzirwa chiwanikwa, izvo chinoita kuti 90% of goridhe.

kugadzira rwakazara

Kune vamwe zvokukura pakusika korona:

• murwere muviri anodyara vose shaya kuti Modelling chigadzirwa kuitwa kwemaminitsi 15 kusvika zvakanga mbishi compression;
• gypsum akacherekedza mutsara prosthesis, zvokuti haana kuenda zvakare paupamhi kana yakamanikana;
• kunoteverwa Modelling wakisi, iro rinoshandiswa varinamire pamusoro - saka, korona (simbi) anogamuchira anatomical chimiro;

• pamusoro-wakavhomorwa simbi womuenzaniso akasika chitambi, riri kumanikidzwa kupinda ruoko;
• rokunze tsikwa rinoitwa uchishandisa sikuruwa muchina;
• chitambi kubviswa, uye chigadzirwa micheto dzinobviswa chaizvo chigero.

Kurimwa nguva kakawanda vachiridzira, chicherwa akava zvinopfuura havanzwi uye simba. Muna prosthesis hakufaniri hadzina kufambiswa zvakanaka uye makatsemuka.

Zvairatidza kuti kugadzwa jira simbi presswork

Kugadzwa simbi korona anoteererwa:

• pre-prosthetic mwana zino wayo kugara change;
• kuponesa utano zino;
• sezvo unokosha chezvinonhuwira kugadzwa kuva zambuko ;
• kana zino iri saka vakakuvadzwa kana damage caries kuti hazvibviri kuti atangezve chisimbiso.

The kugadzwa kwacho korona

chiitiko ichi kunowanzoitwa muna 2 mumatanho:

1. Pakutanga, chigadzirwa anoiswa kwenguva pfupi, saka kuti chiremba anogona kuchengeta maitiro zino.
2. Kana murwere haadi chokunyunyuta pamusoro marwadzo, unotevera kushanya korona hwaputswa, anatswa pedyo rokutanga uye samende wakaiswa patsva, asi nokuda zingi phosphate kana girazi ionomer.

Kana mugumisiro wokutanga chokugadza akawana kuti simbi korona (mufananidzo pasi apa) zviri kukonzera murwere kusanzwa, ipapo zvichabviswa uye achaita kubata zvakare.

Chii inofanira kunyatsobudiswa iiswe chigadzirwa

True zvinogadzirwa uye akapa parutivi korona:

• zvakaoma goko adjoins kuti zino;
• It ane mvere, kukwenenzverwa chimiro;
• periodontal sags vari rusesi pamusoro 0.2 mm;
• reproduces ari anatomical Maumbirwe matadza zino;
• neVadzidzi pedyo uye rinopikisa mazino.

Contraindications yokugadza

kwete varumbidzwa kuisa simbi korona Mune zvimwe zviitiko, kana paine:

• bruxism;
• neutachiona pakuvapo simbi;
• malocclusion dentition;
• oneka kukuvara mupenyu zino;
• dzakaoma nokuda murombo aesthetics pamwe Anterior meno prosthetic.

Zvakaipei ane korona simbi

Mumamwe mamiriro ezvinhu, chigadzirwa ichi kunogona kukuvadza:

1. Nokuda kwayo kugadzwa kuonekwe galvanic syndrome. Izvi imhaka kushandisa alloys anoverengeka kusika munhu prosthetic marongerwo. Nokusanganisa zvinhu zvakasiyana inotungamirira paumbwe imwe galvanic kuitika. Kune nomusoro, kuzvimba, zvimwe zvirwere, esimbi kuravira, kushaya hope, ichipfuta mumuromo.
2. Crown (extruded) hakuiti pasangano vakaparadzana runodzinga, saka zviri kukodzera kuti kuzoita mashandiro anoita nezino mupenyu yakakwana.
3. The chigadzirwa haisi kunyatsotevera yakabatana zino, ndinosika intermedia madziro lumen, izvo zvinopfuura zvasara. Saka, zvinogona kuuya pasi kuora utano tishu.
4. Korona-kuumbwa akasiyana zvakanaka chafariz conductivity. Kana hwakaiswa pamusoro nedepulpirovanny zino, panguva womuchato zvokudya inopisa rinogona kuonekwa hachifadzi nezvekufadza.

Ageless Michina

Production korona simbi iri "muduku zvachose" mumakore ano remakore, izvo anenge modernized mumakore achangopfuura. Pamwe nevamwe ano uye mufashoni nzira prosthesis zvachose, akagara dzakakurumbira. Izvi hazvishamisi, sezvo chikuru chikonzero kukosha zvakadai - yakaderera mutengo prosthesis dzakakwirira simba.
