Crown-molded hlau: duab, xyuas, installation. Qhuav ntawm hlau crowns rau cov hniav

Hlau crowns rau ntawm cov hniav tseem nrov, raws li muaj yog tsis muaj dab tsi tsis tau muaj kev ruaj ntseg thiab muaj zog nyob rau hauv cov khoom cuav tsis tau yees ua. Tej khoom los ntawm ancient sij hawm peb pog koob yawg koob, thiab lawv tseem mus txuas ntxiv mus ua hauj lwm rau cov neeg ntawm lawv cov durability. Txawm hais tias daim ntawv nyob rau hauv crowns tsis yog lub feem ntau txaus nyiam, tab sis tus nqi thiab zoo sib haum mus rau kev muaj tiag.

Yuav ua li cas yog no

Crown-molded ib tug nws yog xim hlau tsab xov xwm uas yog tsim los ntawm txawv alloys ntawm titanium hlau hromokobaltovogo, npib tsib xee-chromium, thiab nws tsim yog kiag li molded. Lub ntsiab daim ntawv thov cheeb tsam ntawm no ntau yam ntawm crowns - hniav cuav hom zom hniav. Qhov no yog vim lawv txom nyem aesthetic tivthaiv.

Crown (hlau) yuav yog ib tug precision-molded tsab xov xwm uas tab sis yog txawv nws yog xim hlau xim, tab sis heev khov kho zaum nyob rau hauv lub qhov ncauj. Tej crowns - ib qho kev yoj rau long-term hniav.

Qhov zoo ntawm chav tsev-cam khwb cia khoom

Xws li ib tug cov ntaub ntawv uas muaj ib tug xov tooj ntawm zoo, namely:

1. Nruj nreem nyob ib sab mus rau lub hniav qauv.
2. Muaj kev ruaj ntseg (cov hniav tsis txhob ua txhaum thiab tsis muab siab npuab).
3. Txawv ntuj anatomical zoo.
4. Ib tug me me nqi piv rau lwm yam cov phooj ywg.
5. Nws tsis lwv cov tawm tsam cov hniav.
6. Remarkably resumes zom ua tau zoo.

Yog vim li cas rau nruab

Kws txawj qhia kom muab hlau crowns xwb nyob rau hauv tej yam mob:

• rhuav tshem cov uas sawv daws yuav cov hniav yog ib lub luag hauj lwm rau kev zom khoom;
• seem ntawm lub puab tsaig ntawm ib tug xov tooj ntawm ntau lov;
• hniav yog heev puas los yog raug mob;
• cov hniav yog kev cog hniav.

Yuav kom muab tso xws li ib tug khoom, koj yuav xav tau ib tug tsawg kawg nkaus ntawm ob tug lub sij hawm rov qab los rau tus kws kho hniav-orthopedist. Ua ntej, tus kws kho mob paub txog lub qhov ncauj radiographs jaws ces pib cov kev kho hniav kho ntawm caries, uas yuav tsum tau ntsia los ntawm ib tug hlau yas. Los ntawm cov chaw uas lub tswv yim npaj raws los yog kev npaj, tshem tawm ib tug paj.

Crown Hlau: hom

Feem ntau, thaum ib tug neeg mob yuav nug txog kev pab rau tus kws kho hniav mus rau qhov chaw hauv lub crown ntawm cov hlau, nws yog muaj ob qho kev xaiv, nyob ntawm seb cov qauv ntawm cov ntau lawm:

1. Diecast khoom. Nws yuav ua ntawm tshwj xeeb casts los ntawm ci nyob rau hauv ib qhov cub. Qhov no yas yog yus muaj los ntawm tuab phab ntsa, uas favorably muaj feem xyuam rau cov kev pab cuam lub neej. Nws yog tsim los ntawm ib lub hauv paus (chromium alloys, npib tsib xee, steel) thiab noble co (platinum, palladium, kub, silver) hlau. Vim hais tias steel coloring khoom tsuas sab prosthetic hniav muab zais thaum lub sij hawm ib tug sib tham. Lawv optimally suited rau cov prosthetic posterior hniav vim hais tias nws muaj peev xwm mas loj loads.
2. Stamped tsis crown yog raug lub tes tsho, uas yog polished nrog ib tug tshwj xeeb lub tshuab los muab cov khoom lub Desired zoo.

Modeling cam khwb cia crowns

Xws li ib tug khoom yog ib tug txhim khu kev qha ib prosthesis thiab ntsia los ntawm ib tug cobalt chrome hlau. Crown (hlau), cam khwb steel muaj indisputable superiority - nws tsis muaj solder pob qij txha, thiab qhov no yuav ua rau nws tshwj xeeb yog khov kho. Nws yog zoo them grinded hniav, tsis tas cov sib tov rau disperse lub MAAs thiab txo qhov yuav tshwm ntawm tob tob hauv qab nws cov zaub mov. kev khiav hauj lwm lub sij hawm - 15-20 xyoo. Modeling cam khwb cia crowns accommodates ob peb cov ntsiab lus:

• los ntawm txhaj tshuaj ntawm lub prosthesis;
• hniav npaj (tshem tawm los ntawm 0.2 mus 0.6 hli ntaub so ntswg);
• zus tau tej cov ciab hau stitched los ntawm;
• kho kom zoo nkauj, haum yog, polishing cov hlau nto;
• snapshots, xws li tawm tsam thiab nyob ib sab hniav.

Piv txwv ntawm xws khoom

Tam sim no, nyob rau hauv lub chaw ua hauj lwm ntawm ib tug kws kho hniav-orthopedist muab-cam khwb cia rau hlau crowns (tswv yim txog lawv los ntawm feem ntau ntawm cov neeg mob yuav tsum hnov xwb zoo) ntawm ob peb hom:

1. Uncoated - yooj yim cov khoom steel xim.
2. Nrog sputtering. Yog hais tias tus neeg mob tsis haum no "kev zoo nkauj", nrog nws txoj kev xav rau crown yuav ua tau los ntawm txau, xyaum kub.
3. Coated. Xam tias yog ntau aesthetically pleasing khoom, hlua nrog ceramics. Lawv pem hauv ntej sab yog them nrog tej hub hauv ob sab phlu. Txawm li cas los, nws yuav tsum tsis tshua muaj neeg ceev faj thaum noj mov, vim hais tias ceramics yuav chais ya cov plaub.
4. Chav. Thaum zoo li no prosthetic yas feem yog them nrog ceramics, thiab lwm tus neeg uas muab zais thaum lub luag ua rau tsis muaj cladding.

stamped yas

Prostheses yog manufactured los ntawm lub Hoobkas zoo li, uas muab cov kev tsim nyog rau daim ntawv. Khoom yog ntawm nyias tus neeg zoo li, li ntawd, yog tsis muaj yuav tsum tau rau ib tug loj tus naj npawb ntawm cov hniav los ntawm kev sib tsoo ntaub so ntswg. Lub crown (hlau) yog muab yog hais tias muaj yog tsis muaj kev puas tsuaj ntawm cov keeb kwm, thiab khaws cia 1/3 hniav. Rau nws lawm yog siv kub los yog stainless hlau.

Cov yooj yim ntawm kev tsim txhais tsis tsuas tsis muaj nqi, raws li zoo raws li ib tug me me lub neej ntawm cov khoom. Kub stamped yas ua los ntawm alloy, uas tso nyiaj rau 90% ntawm lub kub.

raug theem

Muaj tej yam theem ntawm kev tsim ib crown:

• neeg mob ib ce muaj zog casts ntawm ob lub puab tsaig rau modeling cov khoom yuav tsum tau nqa tawm rau 15 feeb mus txog rau thaum nws yog nyoos compression;
• gypsum cim kab ntawm lub prosthesis, yog li ntawd nws tsis tau mus sab heev los yog nqaim;
• ua raws li los ntawm modeling ciab, uas yog thov mus rau lub plaster nto - yog li, lub crown (hlau) tau txais anatomical zoo lawm;

• on-twv steel qauv tsim stamp, uas yog yuam mus rau hauv lub tes tsho;
• txheej Stamping yog nqa tawm siv ib tug ntsia hlau xovxwm;
• stamp muab tshem tawm, thiab cov khoom npoo yog txiav nrog tshwj xeeb txiab.

Lub ntau lawm lub sij hawm yog pheej firing, cov hlau ua ntau tshaj unyielding thiab muaj zog. Nyob rau hauv lub prosthesis yuav tsum tsis txhob yuav irregularities thiab tej kab nrib pleb.

Indications rau lub installation ntawm daim ntawv hlau presswork

Txhim kho hlau crowns ua:

• pre-prosthetic tus me nyuam cov hniav rau nws qhov kev hloov;
• txuag noj qab nyob zoo hniav;
• raws li ib tug tseem ceeb ntawm lub installation ntawm tus choj ;
• yog hais tias tus hniav yog li ntawd raug mob los yog puas los ntawm caries hais tias nws yog tsis yooj yim sua rau rov pib dua lub foob.

Lub installation txheej txheem crowns

Qhov kev tshwm sim feem ntau yog yuav siv sij hawm qhov chaw nyob rau hauv 2 theem:

1. Chiv, cov khoom yog muab tso rau ib ntus, yog li ntawd tus kws kho mob yuav soj ntsuam cov tshuaj tiv thaiv ntawm tus hniav.
2. Yog hais tias tus neeg mob tsis yws ntawm kev mob, nyob rau tom ntej no mus ntsib yas yog muab tshem tawm, yog kev dawb huv los ntawm ib yam ua ntej thiab ib tug xis mas teem anew, tab sis los ntawm zinc phosphate los yog iav ionomer.

Yog hais tias lub txiaj ntsim ntawm tus thawj installation pom tias hlau yas (daim duab qhia hauv qab no) yog yuav ua rau tus neeg mob tsis xis nyob, ces nws yuav tau muab tshem tawm thiab yuav ua dua.

Yuav ua li cas yuav tsum tau zoo ntsia khoom

Yeej muaj tseeb ua thiab nkag los rau hauv lub crown:

• nyuaj plhaub adjoins tus hniav;
• Nws muaj ib tug tus, polished daim ntawv;
• ncig sags nyob rau hauv ib tug so ntawm 0.2 hli;
• reproduces lub anatomical zoo ntawm cov hniav puas hniav;
• nyob rau hauv kev sib cuag nrog lub nyob ib sab thiab opposing hniav.

Contraindications rau nruab

tsis pom zoo kom muab tso rau ib tug hlau yas Nyob rau hauv tej rooj plaub, yog tias muaj:

• bruxism;
• kev tsis haum tshuaj mus rau lub xub ntiag ntawm steel;
• malocclusion dentition;
• perceptible kev puas tsuaj rau nyob hniav;
• complex vim cov neeg pluag kom zoo nkauj nrog prosthetic anterior cov hniav.

Kev phem dab tsi muaj hlau yas

Nyob rau hauv tej lub sijhawm, cov khoom no yuav ua rau kev puas tsuaj:

1. Vim nws installation yuav tshwm sim galvanic syndrome. Qhov no yog vim kev siv ntawm ob peb alloys rau tsim ib tug prosthetic qauv. Nws ntaub ntawv sib txawv ua rau cov tsim ntawm ib tug galvanic tam sim no. Muaj mob taub hau, o, ib co kab mob, nws yog xim hlau saj, insomnia, hlawv nyob rau hauv lub qhov ncauj.
2. Crown (extruded) tsis tsim nyob rau hauv nyias muaj nyias ib casts, yog li ntawd nws yog unsuitable rau ib tug txaus rov qab los ntawm kev khiav dej num ntawm ib tug nyob hniav.
3. Cov khoom no tsis zoo uas nyob ib sab mus rau lub hniav, tsim Intermedia phab ntsa ntawm lub lumen, uas txeem qhov seem cia. Yog li ntawd, tej zaum nws yuav tuaj nyob rau hauv lub lwj ntawm noj nqaij.
4. Crown-molded txawv zoo thermal conductivity. Yog hais tias nws twb tau muab tso rau hauv nedepulpirovanny hniav, thaum lub sij hawm lub txais tos ntawm zaub mov kub yuav tshwm sim tsis kaj siab ncus.

ageless technology

Qhuav ntawm hlau crowns yog "mus ib txhis hluas" ntawm yav dhau los xyoo pua technology, uas zoo modernized nyob rau hauv xyoo tsis ntev los. Nrog rau ib co tshiab thiab fashionable txoj kev ntawm mus tas li prosthesis, nws tseem li nrov. Qhov no yog vim li, txij thaum lub ntsiab yog vim li cas ntawm tej qhov tseeb - tsis muaj nqi prosthesis uas muaj zog.
