Gutta-percha zikhomo mu mano: chithunzi, ikulongosola za

mavuto mano angakhale chikhalidwe chosiyana, ndi njira kuthetsa iwo, pali zambiri. Choncho, gutta-percha zikhomo akhoza kukuthandizani kukhala dzino atengeke wovulala, kulimbikitsa mizu ndipo motero kupereka mwayi kuti amakana kuchotsa.

ndi zikhomo chiyani?

Mano anawononga pa zifukwa zosiyanasiyana: caries, si kugwilizana ndi ukhondo, matenda kagayidwe kachakudya zakudya m'thupi, kuvulala makina ndi kugwazidwa. Kuonongeka dzino kwenikweni si kuchotsedwa, iwo akhoza kubwezeretsedwa. Ngakhale panali kokha muzu, pali njira kuti abwezeretse izo - zikhomo mano. Mapulani, umene ndi ndodo, anakonza chidwi mizu ndi kuthandiza dzino limzake. Pali milandu pamene unsembe wa Ndiuze - ichi ndi chokhacho zotheka njira. Zikuonetsa ntchito:

• korona wa dzino anawononga 50% kapena kuposa,
• dzino ali inawonongedwa, koma amakhalabe muzu lonse,
• kulasa monga kuthandiza korona kapena mtundu wina wa ziwalo zochotseka ndi lokhazikika.

Chikhomo ndi ofanana mu mawonekedwe ndi cholinga cha m'mimba ndi. Ndizo basi amadzala amene anaika mu m'kamwa ndi nsagwada fupa ndi pini - mu ngalande mizu. Kupanga zikhomo ntchito zipangizo zosiyanasiyana: zitsulo, ceramic, fiberglass, uglerodovolokno. Kale m'ma ntchito zikhomo gutta-percha, amene adakali sanataye kufunika kwake.

Gutta-percha monga mfundo chokanikiza

Gutta-percha analandira mwa processing lalabala. Nkhanizi ndi olimba, koma pulasitiki, wangwiro wosindikiza mizu ngalande. Pa kutentha, misa amakhala zofewa ndi malleable, mmenemo osati m'munsi njira, komanso nthambi zake kwathunthu kutseka malemba. Chithandizo cha ichi akudutsa mwamsanga ndi chiopsezo kochepa matendawo. mitundu analipo a gutta - Alpha ndi beta. Pins gutta-percha wopangidwa makamaka a mtundu beta: lili ndi kugwirizana abwino.

Ubwino ndi kuipa kwa gutta percha

Kuwonjezera ofewa, nkhungu ake pulasitiki, mosavuta kulola kwathunthu mudzaze mizu ngalande, ndi gutta percha angapo ubwino.

• Ndi bwino biologically yogwirizana ndi zimakhala a dzino.
• Wangwiro ndi pa elasticity yomweyo.
• nkhaniyo ili si poizoni ndi hypoallergenic.
• Pamene kuumitsa amatenga mawonekedwe.
• Ndi avale yaitali si achotsa, osati odzipereka ndipo alibe kugwa.
• N'zotheka kuchotsa zinthu m'njira muzu, ngati zinthu zitavuta.
• mtengo angagulidwe.
• Pa X-ray ingathandize kuona gutta-percha pini, chithunzi kusonyezedwa njira onse a nthambi, kulola mano wa kufufuza zotsatira za mankhwala ndi kuthetsa deficiencies likafunika.

Osati wopanda zikhomo gutta-percha ndi kuipa:

• Gutta-percha alibe guluu wolimba ndi zovuta minofu dzino.
• Payenera katundu bactericidal.
• N'zovuta kukhazikitsa chifukwa cha ductility mkulu. Kupeza zotsatira zabwino amasewera yofunika akatswiri dokotala.

Features gutta percha

Gutta percha mu mano zosiyanasiyana kukula, pali zazikulu ndi zazing'ono. Ali ndi nambala yapadera kuti limasonyeza makulidwe. Ndi dzino ndi njira boma mano Mzimuyo kukula zomwe ndi makulidwe a chikhomo ntchito pa nkhani zosiyanasiyana.

Komanso, iwo anawagawa muyezo ndi sanali muyezo. Ena kumachitidwa mogwirizana ndi ISO (Organization Mayiko kwa Standardization), ena amasiyana mawonekedwe - iwo ali thicker ndi wamfupi, ndi nsonga mwapang'ono.

Gutta-percha zikhomo ndi 20% zigwirizana beta-percha. Ambiri mwa pafupifupi 75% ya pini m'munsi zopangidwa okusayidi nthaka. Otsala 5% - ichi wothandiza zosakaniza: utoto, plasticizers, komanso chinthu imene pini ndi bwino kuonekera radiograph lapansi.

anatsekera njira. ozizira gutta-percha

Zikhomo ntchito gutta-percha kudzazidwa chidwi muzu ndi ntchito mitundu iwiri ya umisiri - ntchito anachita otentha kapena ozizira zakuthupi. Pa kudzazidwa otentha ndi chuma ndi woyamba mkangano kenako anaikidwa njira zake. Mu ozizira gutta-percha usavutike pambuyo tsamba ake pa muzu.

Anatsekera percha ozizira gutta, nayenso angathe kuchitidwa mu njira zinayi:

• Ndi pini wina. Ntchito molumikizana ndi phala mwapadera, zomwe mano ambiri amakonda kuti asindikize mitsinje. Pamene umagwiritsidwa ntchito pa khoma njira ndi phala umayamba lolingana kukula kwa Ndiuze, kenako gawo owonjezera zace kudula chida otentha. Chifukwa gutta-percha ntchito ozizira, ndi olimba, ndipo likulowerera mu dzino njira, yotsirizira akutumikira kudzaza phala.
• Njira condensation lateral. zikhomo za anayikidwa mu njira bola ngati si kwathunthu zatenga malo. Popanda kwambiri luso ndi zinachitikira mano sangachite, kuyambira zosalongosoka tsamba zikhomo zingachitike muzu wovulala.
• Thermomechanical condensation. Njira ntchito kawirikawiri ndithu ali kuipa ambiri. Kudzaza zikhomo njira amagwiritsa onsewo limagwirira kuti sikubweretsa zotsatira zabwino, chiopsezo kwambiri za kuwonongeka kwa mitsinje.
• Anatsekera gutta anasintha chifukwa cha zochita za mankhwala. Poyamba, njira imeneyi ntchito mano, koma tsopano kuyiwala za izo, chifukwa ali zambiri zolakwa.

otentha gutta-percha

Kodi "otentha" gutta percha? Malongosoledwe a njira imeneyi Zonse zofunikila pansipa. Onani kuti mungachite ngati mankhwala anayi:

• Jekeseni njira. Mabukuwa anali usavutike madigiri 200, imbaenda uliri madzi, ndipo anadzetsa njira. Njira imeneyi zimathandiza kuti kwathunthu mudzaze chimachititsanso onse ndi nthambi. Njira imene chimagwiritsidwa ntchito mano.
• "Thermo" dongosolo. njira zamakono amalola kudya ndi kutseka n'kudzandigunda onse njira pa khama pang'ono, ngakhale zing'onozing'ono. Gutta-percha mu madzi mawonekedwe akudyetsedwa opanikizika mwa ndodo pulasitiki. njira umenewu umatchedwanso buku.
• Ofukula condensation. Imakhala wathunthu njira umphumphu, koma mnjira - zovuta ndi yolemetsa, nthawi yambiri.
• Dyetsani chuma kudzera syringe. njira yosavuta komanso mofulumira, koma sizitanthauza kudzazidwa kwathunthu Komanso gutta-percha simungathe ngakhale ku mapeto a njira, imene kenako chifukwa matendawo.
