Izikhonkwane Gutta-percha in bamazinyo: ifoto, inkcazelo

iingxaki zamazinyo kunokuba abe sisidalwa ezahlukeneyo, kunye neendlela zokusombulula kubo, zininzi. Ngoko ke, nezikhonkwane gutta-percha nga kunceda ekugcineni izinyo semngciphekweni zaphuka, ukomeleza yingcambu kwaye sinike ithuba kwenkunkuma.

Zintoni izikhonkwane?

Amazinyo okuchithwa ngenxa yezizathu ezahlukeneyo: yidityaniso,-non ukuthotyelwa lwezempilo, ukuphazamiseka pathways, ukungondleki kakuhle, ukwenzakala ngoomatshini kunye chipped. izinyo umonakalo akukho mfuneko isusiwe, oko kubuyiselwa. Enoba kwakukho kuphela ingcambu, kukho indlela ukubuyisela ngayo - izikhonkwane amazinyo. Le design, nto leyo ngentonga, omisiweyo misele iingcambu kwaye ixhasa izinyo ebuyiselweyo. Kukho iimeko xa ukufakelwa isikhonkwane - oku isisombululo kuphela. Iimpawu zibonisa ukuba ukusetyenziswa:

• isithsaba izinyo wamginya yi-50% okanye ngaphezulu,
• izinyo ibhuqiwe ngokupheleleyo, kodwa ihleli ingcambu yonke,
• ukuphina wandixhasa isithsaba okanye olunye uhlobo zitho asuswayo, zalungiswa.

I-PIN efanayo kwimilo kunye nenjongo kweyodwa. Yiloo nto nje emzimbeni zifakwa kwi iintsini, imihlathi bone kunye isikhonkwane - in emila iingcambu. Kuba eyimveliso izikhonkwane zisetyenziswa izinto ezahlukahlukeneyo: metal, yodongwe, fiberglass, uglerodovolokno. Kuba kwinkulungwane kusetyenziswa izikhonkwane gutta-percha elidlulileyo, apho nangoku sele andilahlekwanga ukufaneleka kwayo.

Gutta-percha njenge material ngenxa izikhonkwane

Gutta-percha efunyanwa kuqhutyekekwe latex. Le nto into eqinileyo, kodwa iplastiki, ephelele ngokulitywina misele ingcambu. Kwiqondo lobushushu eliphezulu, ubunzima uba ithambile kwaye oluthambileyo, ugcwalisa kuphela umjelo isiseko, kodwa amasebe awo, ukuvala ngokupheleleyo iindinyana. Unyango le idlula ngokukhawuleza kwaye ingozi encinci yeengxaki. iintlobo okhoyo gutta - alpha beta. Izikhonkwane gutta-percha kwenziwa ikakhulu lefom Beta it a uzinzo efanelekileyo.

Izinto eziluncedo nezingeloncedo of gutta percha

Ukongezelela nalo nezimo, iplastiki, ngokulula uvumela ukugcwalisa ngokupheleleyo ingcambu lomsele, le percha gutta zinezibonelelo ezininzi.

• Kuhle ehambelana eziphilayo kunye nezihlunu yezinyo laso.
• Zinamandla kwaye ngexesha luthambe efanayo.
• Le nto non-ziyityhefu kwaye hypoallergenic.
• Xa lukhuni kuthatha imilo.
• Nge ukuguga ixesha elide ayenziwanga ukuyisusa, kwelifunekayo yaye akafuni ukuyisonga.
• Kuyenzeka ukuba ukususa izinto engcanjini emjelweni, ukuba oko kuyimfuneko.
• ixabiso olufikelelekayo.
• Kwi X-ray ungabona ngokupheleleyo isikhonkwane gutta-percha, photo ubonisa zonke Imiphantsi amasebe, sivumele wamazinyo ukuvavanya iziphumo zonyango kwaye ukuba balungise iziphene xa kufuneka.

Olungenayo izikhonkwane gutta-percha nezingeloncedo:

• Gutta-percha akanayo adhesion ukuba nzima izinyo inyama.
• Kukho na iipropati bactericidal.
• Kunzima ukuseka ngenxa ductility ophezulu. Lokufumana nemiphumo emihle udlala ugqirha ebalulekileyo zobungcali indima.

Iimpawu gutta percha

Gutta percha in woogqirha bamazinyo ziyahluka ngobukhulu, kukho ezinkulu nezincinane. Bathi inani ekhethekileyo esibonakalisa ubukhulu. Ngu izinyo kunye wamazinyo karhulumente channel imisela ukuba ubukhulu kunye Ebubanzini isikhonkwane ezisetyenziswa kwimeko ethile.

Kwakhona, ukuba yahlulwe standard and non-standard. Ezinye zenziwe ngokungqinelana ISO (International Organization for Standardization), abanye ezahluke ngokumila - baba ziyatyeba kwaye elifutshane, kunye icebiso iingqameko.

izikhonkwane Gutta-percha yi-20% kuquka beta-percha. Uninzi malunga nama-75% of base pin eyenziwe zinc oxide. I-5% - oku izithako abancedisayo: idayi, plasticizers, kwakunye into apho isikhonkwane ebonakala gca kule radiograph.

uphawu iindlela. ebandayo gutta-percha

Nezikhonkwane ezisetyenziselwa gutta-percha ukuzaliswa kwale misele ingcambu kunye nokusetyenziswa kweentlobo ezimbini ubugcisa - umsebenzi owenziwa izinto eshushu okanye ebandayo. Xa ukugcwaliswa ukuvutha izibonelelo kuqala itshiswa ngoko afakwe channel yayo. In ebandayo gutta-percha elibaselwe ngumoji emva tab yawo ingcambu.

Uphawu percha gutta abandayo, nazo, inokwenziwa ngeendlela ezine:

• Nge pin enye. Ukusetyenziswa kudibaniso nge ngesithambiso ezizodwa, apho oogqirha bamazinyo abaninzi bakhetha uphawu amajelo. Xa oku lisetyenziswa udonga channel kunye ntlama kuqaliswa ehambelana ubungakanani isikhonkwane, emva koko isahlulo kwemfuneko yayo kunqunyulwa isixhobo eshushu. Ngenxa yokuba gutta-percha lisetyenziswa ezibandayo, luqine, kwaye lingena singene umjelo izinyo, le yokugqibela isebenza ukuba bazalise le ntlama.
• Iindlela amafu osecaleni. Nezikhonkwane ibekwa imiphantsi okoko nje kuba nkulu ngokupheleleyo isithuba. Ngaphandle eninzi izakhono kunye namava wamazinyo ayikwazi ukukwenza, ekubeni nezikhonkwane tab sinesiphene kwenzeka ingcambu zaphuka.
• amafu Thermomechanical. Le ndlela isetyenziswa kakhulu kunqabile iye neengxaki ezininzi. Ukuze agcwalise izikhonkwane channel isebenzisa indlela ejikelezayo ukuba akuqinisekisi nemiphumo emihle, umngcipheko omkhulu kangaka umonakalo amajelo.
• Uphawu gutta zithanjiswe yintshukumo kweekhemikhali. Ngaphambili, le ndlela iye yasetyenziswa ukuze bamazinyo, kodwa ngoku silibale ngayo, kuba iba ezininzi iziphene.

hot gutta-percha

Yintoni i "ashushu" gutta percha? Inkcazelo yale ndlela ichazwe apha ngezantsi. Qaphela ukuba iinketho impatho enjalo ezine:

• indlela inaliti. Le nkcazelo lenziwa lashushu degrees 200, nto leyo ekhokelela ukuba imeko yayo ulwelo, yaye yaziswa ijelo. Le ndlela yenza kube lula ukuba ugcwalise ngokupheleleyo zonke lihamba kunye namasebe. Le ndlela lisetyenziswa kwi bamazinyo.
• "Thermo" system. ubuchule Modern ivumela ngokukhawuleza uzivale zonke iimpompo itshaneli umgudu encinane, nokuba zincinane. Gutta-percha ngohlobo ulwelo ondliwa phantsi koxinzelelo ngenxa kwentonga zeplastiki. Le ndlela kananjalo ngokuba umthamo.
• amafu nkqo. Inika ngokupheleleyo ingqibelelo channel, kodwa le nkqubo - ukuba nzima kwaye onzima, ixesha elide.
• Yondla izinto nge isirinji. indlela elula ngokukhawuleza, kodwa oko akuthethi isiqinisekiso ukuzaliswa epheleleyo, koko, gutta-percha abakwazi ukufikelela ekupheleni umjelo, leyo koko kungabangela iingxaki.
