Dental Crowns yog dab tsi?

Kev kho hniav yas yog ib qho kev cai- ua kom rov qab los uas npog tag nrho qhov pom ntawm tus hniav (lub anatomical crown). Xav tias nws yog ib qho kev tiv thaiv "cap" tso rau ntawm cov hniav uas tau npaj. Nws lub luag haujlwm yog los kho cov hniav zoo, lub zog, kev ua haujlwm, thiab kev zoo nkauj, thaum tiv thaiv cov hniav seem.

Crowns tsis yog ib qho -puab- haum- tag nrho. Hniav anatomy txawv ntawm qhov chaw thiab kev ua haujlwm:

• Incisors muaj nyias npoo rau txiav cov zaub mov
• Canines muaj qhov sib txawv cusp rau tearing
• Molars yog dav nrog ntau cusps thiab grooves rau kev sib tsoo

Vim li no, crown tsim thiab fabrication yuav tsum yog tus kheej heev.

Vim li cas Dental Crowns siv?

Lub hom phiaj tseem ceeb ntawm lub kaus mom yog los muab kev tiv thaiv tag nrho thiab txhim kho kev ua haujlwm thaum tus hniav tau ploj ntau dhau lawm -xws li los ntawm qhov tob tob los yog kev raug mob - qhov twg ib qho yooj yim txhaws tsis txaus. Crowns kuj feem ntau siv los txhim kho kev zoo nkauj hauv cov hniav uas tsis muaj xim zoo nkauj uas tsis teb zoo rau kev ntxuav hniav dawb.

Cov Khoom Siv Kho Hniav Hniav: Hom, Pros thiab Cons

Kev kho hniav niaj hnub muaj ntau yam khoom siv yas. Txhua tus muaj qhov zoo thiab cov kev txwv, thiab qhov "zoo tshaj" kev xaiv nyob ntawm qhov chaw ntawm cov hniav, tom qab quab yuam, kev cia siab zoo nkauj, keeb kwm tsis haum, thiab pob nyiaj siv.

1) Hlau yas

Cov yas yas yog cov kev xaiv ntau tshaj plaws, feem ntau ua los ntawm npib tsib xee -chromium, cobalt-chromium, lossis kub alloys.

Lub zog

• Muaj zog heev thiab hnav tsis kam
• Kev ua tau zoo heev, tshwj xeeb tshaj yog rau cov hniav tom qab uas zom cov rog muaj zog

Kev txwv

• Kev zoo nkauj tsis zoo: cov xim hlau yog pom tseeb, tshwj xeeb tshaj yog tsis haum rau cov hniav pem hauv ntej
• Qee cov alloys tuaj yeem ua rau muaj kev tsis haum tshuaj (nickel{0}}muaj cov alloys xav tau kev ceev faj ntxiv)
• Tej zaum yuav cuam tshuam nrog MRI hauv qee kis

Nqe sau tseg

Nickel-chromium thiab cobalt-chromium crowns feem ntau pheej yig dua. Kub alloy crowns raug nqi ntau dua tab sis feem ntau muab biocompatibility zoo dua thiab ductility.

2) Tag nrho -Ceramic Crowns

Txhua yam -ceramic crowns tsis muaj hlau thiab tej zaum yuav ua los ntawm cov ntaub ntawv xws li zirconia los yog lithium disilicate.

Lub zog

• Kev zoo nkauj zoo nkauj: xim thiab translucency tuaj yeem ua rau cov hniav zoo nkauj zoo nkauj
• Zoo biocompatibility: tsis tshua muaj kev tsis haum tshuaj, tsis muaj hlau grey kab ntawm cov pos hniav
• Niaj hnub nimno zirconia tuaj yeem ncav cuag lub zog siab, ua rau nws haum rau qee qhov tom qab

Kev txwv

• Tus nqi siab dua (tshwj xeeb yog siab -translucency zirconia)
• Yuav tsum tau npaj cov hniav kom meej dua
• Qee hom ceramic tuaj yeem nti
• Cov ntaub ntawv nyuaj (xws li zirconia) tuaj yeem ua rau hnav ntawm cov hniav tawm tsam hauv qee qhov xwm txheej

3) Porcelain-Fused-rau-Hloov Crowns (PFM)

PFM yas sib xyaw ua ke cov txheej txheem hlau rau lub zog thiab cov plooj (porcelain) txheej txheej rau qhov zoo nkauj dua.

Lub zog

• Sib npaug zog thiab zoo nkauj
• Dav siv rau ob sab pem hauv ntej thiab nram qab cov hniav nyob ntawm cov ntaub ntawv xav tau
• Cov kev xaiv hlau tuaj yeem phim cov peev nyiaj sib txawv (kev lag luam alloys vs ntau biocompatible precious alloys)

Kev txwv

• Cov txheej plooj (porcelain) tuaj yeem tawg thaum lub sijhawm
• Ib txoj kab grey ntawm cov pos hniav tuaj yeem tshwm sim vim yog cov yeeb yam hlau- dhau los, cuam tshuam rau kev zoo nkauj- tshwj xeeb tshaj yog nyob rau pem hauv ntej

4) Resin Crowns

Resin crowns feem ntau yog siv los ua cov yas ib ntus.

Lub zog

• Tus nqi qis thiab yooj yim rau fabricate
• Feem ntau tuaj yeem ua tiav sai
• Siv tau los tiv thaiv cov hniav npaj thaum lub kaus mom zaum kawg tau ua

Kev txwv

• Tsawg zog thiab hnav tsis kam
• Feem ntau yuav ua rau tsis muaj xim, hnav, thiab hnub nyoog
• Tsis zoo tagnrho li kev kho kom ruaj khov nyob rau hauv feem ntau

Resin crowns tuaj yeem muaj txiaj ntsig zoo hauv kev kho hniav menyuam yaus rau luv luv - lub sijhawm kho cov hniav qub, vim cov hniav no yuav raug hloov tom qab.

Cov lus sib piv ceev: Cov khoom siv kho hniav hniav

Daim Ntawv Thov: Thaum twg Koj Xav Tau Hniav Crown?

Tom qab kev kho mob hauv paus kwj dej

Cov hniav uas tau kho cov kwj dej feem ntau ua nkig dhau sijhawm vim tias cov pulp raug tshem tawm. Yog tsis muaj kev tiv thaiv, cov hniav tom qab yuav muaj kev pheej hmoo ntau dua ntawm kev tawg. Lub kaus mom muab kev tiv thaiv txhua yam thiab pab khi cov hniav kom txo qis microleakage thiab rov ua dua tshiab. Qee qhov xwm txheej, yuav tsum muaj kev tshaj tawm - thiab - cov tub ntxhais ua ntej muab lub kaus mom, tshwj xeeb tshaj yog thaum cov hniav seem tsis muaj zog.

Kev txhim kho kom zoo nkauj rau cov teeb meem loj heev los yog cov duab zoo nkauj

Crowns tuaj yeem txhim kho zoo rau cov hniav uas muaj xim tsis zoo (xws li fluorosis, tetracycline staining, lossis discoloration los ntawm pulp necrosis) uas tsis teb zoo rau kev ntxuav hniav dawb. Crowns kuj tuaj yeem hloov kho cov hniav nrog kev loj hlob tsis xws luag, deformities, lossis hnav ntau dhau los ua kom muaj kev sib raug zoo luag nyav.

Implant Crowns

Nyob rau hauv kev kho mob implantation, lub crown yog pom, haumxeeb ib feem muab tso rau ntawm ib tug cog ntawm ib tug abutment. Cov khoom siv thiab kev tsim qauv yuav tsum xav txog kev sib tsoo quab yuam, kev zoo nkauj, thiab cov pos hniav nyob ib puag ncig. Zirconia yog nce nrov rau kev cog qoob loo vim nws cov biocompatibility thiab zoo li.

Lwm yam xwm txheej

Crowns kuj tseem siv tau rau hauv:

• Qee qhov xwm txheej orthodontic (feem ntau kev tiv thaiv ib ntus lossis kev npaj ua kom zoo nkauj)
• Bruxism (kom faib cov zog txawv txav nrog kev tsim tshwj xeeb)
• Rebuilding ntsug dimension nyob rau hauv hnyav generalized hnav

Yuav Ua Li Cas Xaiv Txoj Cai Kho Hniav Crown

1) Hniav qhov chaw: Pem hauv ntej vs Back

• Cov hniav pem hauv ntej (anterior) feem ntau yog qhov tseem ceeb rau kev zoo nkauj → tag nrho -ceramic crowns feem ntau nyiam
• Cov hniav rov qab (tom qab) ua ntej lub zog thiab ua haujlwm ntev → hlau yas, siab - lub zog zirconia, lossis PFM yuav zoo dua nyob ntawm koj qhov tom thiab tus cwj pwm

Yog tias koj muaj txoj kab luag nyav siab (ntau cov pos hniav qhia), cov paj paj zoo nkauj ua qhov tseem ceeb dua thiab tuaj yeem cuam tshuam cov khoom xaiv.

2) Hnub nyoog-Txoj kev xav txog

• Cov menyuam yaus: stainless hlau- hom hlau yas feem ntau yog siv rau cov kab mob loj zuj zus vim qhov ua tau ntev thiab ua tau zoo

Cov nqi sib txawv:

• Hlau thiab resin crowns feem ntau yog tus nqi qis dua
• PFM feem ntau yog nruab nrab -ntau yam
• Txhua yam -ceramic (tshwj xeeb tshaj yog zirconia) feem ntau yog tus nqi siab tshaj

Txawm li cas los xij, qhov kev txiav txim siab yuav tsum tsis yog raws li tus nqi pib xwb. Qhov zoo dua - haum, tsim nyog lub kaus mom yuav kav ntev dua thiab txo cov nqi kho lossis hloov pauv yav tom ntej.

5) Kev ntsuam xyuas kev tshaj lij thiab tus kheej tsim

Tus kws kho hniav cov lus pom zoo yuav tsum yog raws li kev kuaj mob tag nrho: cov qauv ntawm cov hniav seem, cov pos hniav noj qab haus huv, occlusion, thiab koj tus kheej cov teeb meem. Digital scanning thiab CAD / CAM kev tsim khoom tuaj yeem txhim kho qhov tseeb thiab tus kheej.

Kev Kho Hniav Crown Care thiab Kho

Ib lub kaus mom nws tus kheej tsis tau cov kab noj hniav, tab sis cov npoo npoo npoo (qhov twg cov yas tau raws li cov hniav ntuj) yog qhov muaj kev pheej hmoo siab rau cov quav hniav.

Txhua Hnub Hniav Qhov ncauj

Cov cim qhia pom

• Tom zoo li "siab" lossis tsis xis nyob
• rhiab heev nyob ze ntawm lub crown ntug
• Cov pos hniav liab, o, los ntshav
• Crown xav tias xoob (nrhiav kev saib xyuas tam sim ntawd)

Cov porcelain chips me me tej zaum yuav raug kho, tab sis cov pob txha loj dua feem ntau yuav tsum tau hloov. Tsis tas li ntawd, txawm tias lub kaus mom tsis zoo, cov hniav hauv qab tseem tuaj yeem tsim teeb meem, yog li lub sij hawm X-rays tuaj yeem pab tau thaum ntxov.

Xaus

Cov hniav nyiaj hniav kub kho hniav zoo, ua haujlwm, thiab zoo nkauj thaum tiv thaiv cov hniav tsis muaj zog. Los ntawm cov tsoos hlau yas mus rau niaj hnub zirconia tag nrho -ceramic crowns, cov ntaub ntawv tau txhim kho thiab kev xaiv tau nthuav dav. Tab sis tsis muaj ib qho zoo tshaj plaws cov khoom siv yas-tsuas yog qhov kev xaiv uas zoo tshaj plaws rau koj txoj hauj lwm hniav, kev xav tau, lub hom phiaj zoo nkauj, qhov ncauj ib puag ncig, thiab pob nyiaj siv.
