Chii chinonzi mazino burs?

Dental burs chikamu chakakosha chemazuva ese general dentistry. Zviridzwa zvinotenderedzwa, zvakagadzirirwa kucheka zvinyama zvakaoma senge enamel yezino kana bhonzo, zvinouya mumhando dzakasiyana-siyana, saizi uye grits ane maviri kana anopfuura akapinza - epamucheto uye akawanda ekucheka echeto.

Yakashandiswa kare mukugadzirira kudzoreredza mazino semidziyo yekutanga yekucheka, sainzi uye tekinoroji zvakafambisa kusimudzira kweubiquitous bur kusvika kune hurefu hutsva, iko zvino kusanganisa huwandu hwakakura hwesarudzo kuendesa akasiyana maitiro emazino.

Inokurumidza kusimba uye yemhando yepamusoro, mazino maburs anogadzirwa nesimbi, simbi isina tsvina, tungsten carbide uye diamond grit.

Bhara rimwe nerimwe rinouya muzvikamu zvitatu - musoro, mutsipa uye shank.

• Musoro une blade inotenderera ichicheka nyama.
• Mutsipa wakabatanidzwa nemusoro, une blade yekucheka kana Bur.
• Shank ndiyo yakareba chikamu chebur piece. Iine migumo yakasiyana yekubatanidza kumhando dzakasiyana dzemaoko.

Mhando nhatu dze shank ndeidzi:

Akareba akatwasuka/handpiece burs (HP): Mahombe, akareba akatwasuka mashank marudzi uye anoshandiswa pane anononoka kumhanya handpieces.

Latch-rudzi/kurudyi kona (RA): Aya anonamira kune low speed contra-ekona handpieces.

Kubata-bata (FG): Aya anoshandiswa ane high speed handpieces.

Iwo anoshandiswa neakakwirira-emaoko anomhanya uye anowanzo kupatsanurwa nechimiro chawo - koni, denderedzwa kana pfumo. Mukuita sarudzo yakanaka yebur, maitiro avo akasiyana-siyana anowanikwa mune blade angle uye nzvimbo, chimiro chemusoro, uye mukuputsika kwegrit.

Muchidimbu:

Round Burs - kubviswa kwezvizhinji zvekuora mazino, kugadzirira mhango, kuchera nekugadzira nzvimbo dzekuwana uye nzira dzema blades re: kubviswa kwemazino.

Flat-end Burs - kubviswa kwechimiro chezino, rotary intra - kugadzirira zino remuromo kugadzirisa.

Pear Burs- kugadzira undercut yekuzadza zvinhu, kuchera, kucheka uye kupedzisa.

Muchinjikwa-kucheka Tapered Fissure - yakanakira gadziriro chaidzo uku uchidzikamisa kuvaka - kuunganidzwa kwemarara, senge mukushanda kwekorona.

Kupedzisa maBurs anoshandiswa mukupedzisa kudzoreredza.

Kufanana nesandpaper, mabhura anouya mumagiredhi akasiyana ehukasha. Muchidimbu, iyo abrasiveness inosiyana kuti ienderane nemabasa akasiyana. Iyo yakaoma iyo grit, iyo yakawanda mazino pamusoro ichabviswa. Magrits akakwenenzverwa anonyatsokodzera kushanda zvinoda ruzivo rwakakwana, senge kutsvedzerera kwemipendero yakakasharara kana kutenderedza mupendero. Ndeapi marudzi akasiyana emazino?

Huwandu hwemabhura anowanikwa kuna vanachiremba vemazino hwakakura, uye kusarudza iyo yakanyatsokodzera sarudzo kunogona kuvandudza zvakanyanya basa rekiriniki. Zvakanakisa, izvi zvinogona kuitwa padanho rekuronga kurapwa.

Iyo yakazara yakazara maburs inosanganisira:

Sterile Diamond Burs: Pre - sterilized kuitira kuti ishandiswe nekukasira, mabhurashi aya anoshandisa madhaimani emhando yekucheka akavimbika kuti ashandiswe nguva nenguva.

Gold Diamond Burs: Yakagadzirwa neakanakisa eSwitzerland Iwo akasimba, anogara uye anovimbisa kushanda kwepamusoro.

Twister Diamond Burs: Yakaputirwa nedhaimani rechisikigo, ivo vanopa isiri - kuvhara spiral mbiri chiito vachishandisa chaiyo yakagadzirwa musoro kuti ikurumidze kushanda uye kushoma kuramba. Yakanakira kukurumidza kuderedza kuwanda uye kupera kwakatsetseka.

Steel Burs: Yakagadzirirwa kuzunguzika kushoma kunogona kutungamira mukukuvadzwa kwehandpiece uye kusagadzikana kwemurwere, izvi zvinogadzirwa kubva pakupisa zvinorapika alloy simbi kune yakanyanya kusimba uye kuvimbika.

Tungsten Carbide Burs: Yakagadzirwa neyakaomeswa zvinhu, izvi zvinoshanda zvakanyanya uye zvakapinza kucheka chishandiso. Ivo vanopa inokurumidza, yakatsetseka, vibration - yemahara kuita, kuendesa nyaradzo yemurwere uye yakaderedzwa yekushanda nguva.

Zvese zvinouya muHP, RA uye FG fittings.

chero yemazuva ano mabhureki anowanikwa mune isina mbereko, imwe chete kushandiswa mapaketi, kuve nechokwadi chekutonga kwehutachiwana kwakanyanya - kunonyanya kukosha mumamiriro ekunze anhasi.

Single - shandisa mabhura zvakare anodhura - anoshanda (hapana chikonzero chesterilisation), kinder kune mahandpieces (hapana kuvhara nemarara) uye murwere - ane hushamwari (100% inoshanda kwese kushandiswa nokudaro kuve nechokwadi kunyaradzwa kukuru).

Nderipi bhura rinofanira kushandiswa pakurapa kwega kwega?

Mabhara ekuvhiya: Inoshandiswa mukuvhiyiwa nemuromo, nhasi kuvhiyiwa bur kazhinji ndeyeTungsten Carbide kana Diamond, zvinoreva kuti yakasimba uye inogara uye inopa kushanda kwepamusoro.

Diamond Burs aanoshandiswa kukuya matishu emazino nekucheka porcelain, uye anonyanya kushandiswa neakakwirira-emaoko anomhanya kusiya kupera kwakashata.

Tungsten Carbide Burs zvakare akagadzirirwa optimum simba, kusimba uye kuita. Zvakaoma katatu kudarika simbi, aya magadzirirwo emazino akatsetseka kusvika pakupedzwa kwakanaka.

Restoratives Burs: Diamond Burs anonyatso kufanira kucheka porcelain kudzorera zvinhu.

Tungsten Carbide Burs chip kure pachimiro chezino uye inoshanda pakubvisa kudzoreredza kwesimbi pamwe nekuchekerera nekupedzisa macomposites. Inogona kushandiswa kuchera uye kugadzirira mhango yekuzadza, kubviswa kwezvinhu zvekare zvekuzadza uye pfupa rekutenderera. Anogona zvakare kushandiswa kubviswa kwemazino akabatwa, uye kupatsanura korona nemabhiriji. Vanosiya nzvimbo yakatsetseka kupfuura Diamond Bur.

Flat - kupera Cylinder Burs anoshandiswa kugadzirira intra-oral mazino.

Inverted Cone Burs akakodzera kudzikisa mukana wekuvhura kwemidzi migero kana kudzoreredza. Zvinogona zvakare kushandiswa kudzikamisa pulpal kana gingival madziro.

Round - kupera Taper Bur anoshandiswa intra-nomuromo mazino kugadzirira uye kugadzirisa.

Steel Burs dzakanakira kugadzirira mhango uye kubvisa mazino.

Orthodontic Burs: A Tungsten Carbide Bur mune contra-ekona handpiece inogona kushandiswa kupindirana kuderedza, de - kubatanidza uye inofanotaurwa uye yakachengeteka resin kubviswa, ine kushoma kukuvadzwa kune zino enamel, pamwe nekuzotevera enamel polishing.

Laboratory Burs: Ceramic Burs yakanyatsokodzera kugadzirisa acrylic uye thermoplastics.

• Steel Bursdzakagadzirirwa kushandura acrylic zvinhu, senge dentures uye tsika tireyi. Ivo vane yakanaka kumucheto kuchengetedza uye vanoshingirira kuabrasion.

Nemhando dzakasiyana-siyana dze shank masitaera uye maumbirwo emusoro, varapi vanogona kusarudza yakanakisa sarudzo kubva pane yakafara sarudzo ine epamusoro dhizaini maficha.
