Ni gute irangi ry'amabara rifasha mu kunoza imikorere y'umubiri ku barwayi b'ingimbi bavura amagufwa?

Intangiriro

Ubuvuzi bw'amenyo y'ingimbi bushingira cyane ku myitwarire ndetse no ku mikorere, kandi kwambara elastic buri munsi akenshi niho gahunda zihagarara. Ikintu kimwe gitangaje gitera imbaraga ni amabara: guha abangavu amahitamo y'elastic y'amabara bishobora gutuma ubuvuzi bwumvikana nk'ubw'umuntu ku giti cye, bugaragara, kandi bworoshye kwiyemeza. Iyi nkuru isobanura uburyo iryo hitamo rito ry'igishushanyo rishyigikira kubahiriza amategeko, impamvu rijyanye n'imitekerereze y'ingimbi, n'icyo rishobora gusobanura ku buryo bunoze bwo kuvurwa, ibisubizo byo kubonana, no kunyurwa n'umurwayi. Ishyiraho kandi ibintu ngirakimazi abaganga n'ababyeyi bagomba kuzirikana iyo bakoresha elastic y'amabara kugira ngo bashishikarize ubufatanye buhamye.

Uburyo Elastics y'amabara menshi ishobora kunoza uburyo iyubahirizwa ry'amategeko y'imyanya y'abangavu

Gukurikiza amabwiriza y’ingimbi n’abangavu biracyari kimwe mu bintu bidasanzwe mu kuvura amenyo. Nubwo iterambere ry’imikanika ryagize imiterere myiza y’amakaramu noinsinga z'umugozi, ibisubizo by'ubuvuzi biracyashingiye cyane ku bufatanye bw'abarwayi, cyane cyane ku bijyanye n'isuku yo mu kanwa nokwambara buri gihe kwa elastike za interarchIgipimo cy’abangavu batagira ubuziranenge mu barwayi ba amenyo y’abangavu gikunze kuba hagati ya 30% na 50%, iki kibazo kikaba gishobora kongera igihe cyo kuvurwa no kwangiza ibisubizo bya nyuma byo mu mutwe.

Kugira ngo ibi bigerweho, abaganga bakoresha cyane uburyo bwo kuvura kugira ngo batere umurwayi icyubahiro mu gihe cyo kuvurwa. Guhuza imigozi y'amabara ya elastomeric na interarch elastiki bikora nk'igikoresho cyo mu mutwe gihendutse kandi gifite ingaruka nyinshi. Mu guhindura uburyo bwo kuvura butagira ingaruka mu buryo buhuriweho, ubuvuzi bwo kuvura bushobora gukoresha imitekerereze y'ingimbi n'abangavu kugira ngo burusheho gukurikiza amabwiriza yanditswe.

Impamvu guhitamo ibintu bifatika ari ingenzi mu gushishikariza urubyiruko

Ubugimbi ni intambwe y'iterambere irangwa n'ubushake bukomeye bwo kwigenga no kwigaragaza. Ubuvuzi bwo kuvura amenyo, bukunze gutegekwa n'ababyeyi kandi bugakorwa n'abaganga, butuma ubwo bushobozi bugabanuka. Kwemerera abangavu guhitamo amabara y'impeta zabo za elastomeric (O-rings) cyangwa interarch elastiki bigarura uburyo bwo kugenzura. Ubushakashatsi ku myitwarire bw'abaganga bwerekana ko gutanga amahitamo mato, agenzurwa mu rwego rw'ubuvuzi bishobora kuzamura amanota y'abarwayi kugeza kuri 40%.

Ubu buryo bwo guhitamo ibikoresho bikoreshwa mu gushushanya buhindura igikoresho cyo gushushanya kiva ku gikoresho cyo kwa muganga gusa kikajya ku gikoresho cyo gukosora. Abarwayi bakunze guhuza amabara yabo n'ibiruhuko, amabara y'ishuri, cyangwa ubwiza bwabo bwite. Ubu buryo bwiza bugabanya isuzuguro n'agahinda bikunze kugaragara ku bikoresho bidahinduka, bigatera abarwayi gutekereza ku buryo bufatika mu gihe cyo gukosora intebe no kwita ku barwayi mu rugo.

Uburyo gukurikiza amategeko bigira ingaruka ku mikorere myiza y'ubuvuzi

Ubuhanga bwo kuvura amenyo bufitanye isano itaziguye no gukoresha imbaraga buri gihe. Ku miti ikoreshwa mu gupima amenyo, abaganga bakunze gutanga amasaha 20 kugeza kuri 22 yo kwambara buri munsi kugira ngo bagere ku ihinduka ryiza ry'amenyo. Iyo imbaraga zigabanutse kandi umurwayi akagabanya igihe cyo kwambara kikagera ku masaha 12 cyangwa munsi yayo, imbaraga za biomechanical ziba nke, bigatuma uturemangingo turuhuka mu mitsi y'amenyo aho kuvugurura amagufwa.

Uku kutubahiriza amategeko bivuze ko ubuvuzi budakora neza. Igihe cyo kuvurwa gishobora kwiyongeraho amezi 3 kugeza kuri 6 bitewe no kwangirika gukabije kw'ingufu, bigasaba gahunda z'inyongera no kwiyongera kw'ibiciro by'inyongera ku ivuriro. Mu gukoresha ingufu z'amabara menshi kugira ngo umurwayi akomeze kugira ishyaka ryo hejuru, abaganga bashobora kwemeza ko uburyo umubiri ukoresha imbaraga zikoreshwa bukomeza kuba bwiza, bityo gahunda yo kuvurwa igakomeza ku murongo.

Impamvu z'ubuvuzi n'imyitwarire zituma habaho ikoreshwa ry'amabara ashyushye

Gukoresha elastomerike z'amabara menshi bisaba gusobanukirwa siyansi y'ibikoresho bigenga ibikoresho bya polyurethane ndetse n'imyitwarire y'urubyiruko. Ibikoresho bya elastomerike biboneka hose mu bijyanye n'imiti, ariko imiterere yabyo ntabwo ihinduka. Kwangirika kw'imbaraga z'imitsi ya elastomerike n'iminyururu akenshi bigera kuri 50% kugeza kuri 70% mu masaha 24 ya mbere yo kwangirika mu kanwa.

Kubera ko ibi bikoresho bisaba gusimbuzwa kenshi—ubusanzwe buri byumweru 4 kugeza kuri 6 kugira ngo bibe bya ligature ndetse buri munsi kugira ngo bibe bya elastomerike nshya—gukenera elastomerike nshya bihoraho bituma umurwayi akomeza gukorana na we. Gusobanukirwa itandukaniro riri hagati y’ibi bicuruzwa n’imyitwarire ituma bikoreshwa ni ingenzi kugira ngo habeho imikorere myiza ya biomechanical ndetse no kubahiriza amategeko y’umurwayi.

Uburyo elasitiki zifite amabara atandukanye n'iy'amabara n'iy'amabara atandukanye

Nubwo abarwayi bakunze gukoresha ijambo "imigozi y'urubura" mu buryo bumwe, abaganga bagomba gutandukanya ligature za elastomeric na elastike za interarch mu gihe bategura ingamba zo kubahiriza amategeko. Ligature za elastomeric (cyangwa impeta za O) zikoreshwa n'umuganga kugira ngo afashe insinga ya archwire mu mwanya w'igitereko. Guhitamo amabara yazo bitanga ubwiza kandi byongera ibyishimo ku gihe cyo kubonana na muganga, ariko ntibisaba umurwayi buri munsi kugira ngo agire icyo akora.

Ku rundi ruhande, elasitiki zo mu bwoko bwa interarch ni imigozi ishobora gukurwaho ikoreshwa mu gukosora ikibazo cyo kubura imyanya nko mu cyiciro cya kabiri cyangwa icya gatatu. Ibi bisaba ko umurwayi akurikiza amabwiriza akomeye, kuko umurwayi agomba kuyikuramo iyo arya kandi akayisimbuza inshuro nyinshi ku munsi imigozi mishya kugira ngo agumane imbaraga zihagije (ubusanzwe kuva kuri ounces 2.5 kugeza kuri 17.0). Gutanga elasitiki zo mu bwoko bwa interarch zifite amabara menshi bihora bimwibutsa umurwayi guhora akoresha gahunda ye ya buri munsi yo kwambara.

Ni ibihe bintu byo mu mutwe n'iby'intebe byongera imbaraga

Ubunararibonye bwo ku ntebe bugira uruhare runini mu gushimangira uburyo umurwayi yubahiriza amategeko. Iyo abafasha mu by'ubuvuzi bw'amenyo bamara iminota 2 kugeza kuri 3 baganira ku mabara atandukanye, byubaka umubano w'ingenzi hagati y'itsinda ry'abaganga n'umurwayi w'ingimbi. Uku gushimangira neza bituma umurwayi yemera neza amabwiriza y'ubuvuzi yerekeye isuku yo mu kanwa no kwambara neza.

Byongeye kandi, ingamba zo gukina imikino y'amahirwe zishobora gukoreshwa. Imyitozo ikunze gukoresha amarushanwa y'ibihe cyangwa ubukangurambaga ku mbuga nkoranyambaga aho abarwayi berekana amabara yabo yihariye. Uku kwemeza ko abantu bahuje igitsina bikoresha imbaraga z'ingimbi zo kwemerwa n'abandi, bigatuma kwambara amabara y'amabara menshi biba imyitwarire ishimishije mu mibereho y'abantu aho kuba umurimo wihariye.

Ni izihe mbogamizi n'ibintu bigena imanza bifite akamaro?

Nubwo bifite akamaro mu myitwarire, elastomerike z'amabara zigaragaza imbogamizi zihariye mu buvuzi. Imiterere y'ibikoresho ni ikintu cy'ingenzi; mu gihe ligature nyinshi z'amabara zigezweho zikozwe muripolyurethane idakoresha latexKugira ngo hirindwe ingaruka z'ubwivumbure, elasitiki zitari za latex interarch zikunze kwangirika vuba kurusha izindi za latex karemano. Abaganga bashobora gukenera gutanga amabwiriza yo kongera imbaraga za mbere hagati ya 10% na 15% ku migozi idakoresha latex kugira ngo bishyure uku kwangirika vuba.

Guhitamo ibara ry'inyuma nabyo bigena uburyo amabara ashobora kubaho. Mu bihe bisaba gukosora cyane mu buryo bwo kuzenguruka cyangwa aho uburyo bwo kuzenguruka butagira uburyaryate ari bwo bw'ingenzi,udukingirizo twishyiramocyangwa ligature z'icyuma kidashonga zishobora kuba ziruta ligature za elastomeric mu buryo bw'umubiri. Muri ibyo bihe, umuganga agomba kuringaniza icyifuzo cy'imyitwarire cyo kubona ligature z'amabara atandukanye n'ibisabwa mu rwego rwo kuvurwa.

Kugereranya Amahitamo y'Amabara n'Ay'Uburinganire

Mu gihe cyo gutegura gahunda yo kuvura, abaganga b'amenyo bagomba gupima ibyiza by'imyitwarire y'amabara ya elastike ugereranije n'imiterere y'ubwiza n'ubuvuzi bw'uburyo butarimo cyangwa busobanutse neza. Uduce tw'ubwiza (ceramic cyangwa safiro) dukunze guhuzwa n'uduce tw'ibara rya elastomeric dusobanutse neza cyangwa dukoresha ibara rya elastomeric kugira ngo tugabanye ubushobozi bwo kubona ibikoresho. Ariko, ubu buryo butarimo imiterere butanga imbogamizi zidasanzwe ku bijyanye no kugumana ibikoresho no kunyurwa n'umurwayi.

Imiyoboro ya elastomeric isobanutse neza ishobora kwangirika cyane. Ubushakashatsi bwerekana ko elastomeric ya polyurethane isobanutse ishobora kugaragaza impinduka igaragara mu ibara (agaciro ka Delta E karenze 3.0) mu minsi 7 gusa iyo ihuye na chromogens mu mirire nka ikawa, icyayi, sinapi, cyangwa turmeric. Uku kwangirika vuba mu isura bishobora kugabanya kunyurwa kw'umurwayi, bigatuma kugereranya amabara n'amahitamo adafite aho ahuriye n'ibara ari ikintu cy'ingenzi cyane mu buvuzi.

Ni ibihe bintu bigereranya neza imiterere, uko bigaragara, n'irangi

Gusuzuma itandukaniro riri hagati ya elastomere z'amabara n'izidafite aho zibogamiye bisaba gusesengura imikorere yazo mu buryo butandukanye bwo kuvura no mu myitwarire. Elastomere z'amabara zipfuka neza irangi ry'imirire, mu gihe amahitamo asobanutse neza arushaho kurikomeza. Byongeye kandi, inyongeramusaruro z'amabara muri elastomere z'amabara ntizihindura cyane imiterere yazo y'imbaraga ugereranije n'impinduka zidafite irangi, bigatuma abaganga bafata ibyemezo bishingiye ahanini ku bwiza n'uko bikurikizwa aho gufata ibyemezo bishingiye ku miterere y'umubiri.

Iyo amahitamo adafite aho abogamiye ashobora kuba amahitamo meza

Nubwo hari inyungu ku myitwarire y’amabara atandukanye, elasitiki zitagira aho zibogamiye cyangwa zisobanutse neza zikomeje kuba amahitamo meza ku bantu runaka ndetse no ku ndwara runaka. Abarwayi bakuru bafite ubumuga bwo kuvura amenyo, bakunze gushyira imbere ubushobozi bwo kwitonda kuruta uko bagaragaza imiterere yabo, bakunda cyane imiterere isobanutse neza ifatanye n’udukingirizo twa kera cyangwa ubuvuzi busobanutse neza. Kuri aba barwayi, imbaraga zo mu mutwe ziva ku kutagaragara kw'igikoresho aho kugihindura uko giteye.

Byongeye kandi, bamwe mu barwayi b'ingimbi baba bafite amakenga menshi ku buzima bwabo kandi bagakunda uburyo bworoshye. Mu gihe hakoreshwa ligature zisobanutse neza ariko ikibazo cyo gusiga irangi mu mirire kikaba ikibazo gihoraho, abaganga bashobora gusimbuza ligature zisobanutse neza n'izifite ibara ry'ifeza cyangwa umwotsi, cyangwa bagahitamo Teflon-coated.imigozi y'icyuma kitagira umwandaIzi mpinduka zigumana imiterere idasobanutse neza mu gihe zirwanya ibara ryihuse rigaragara mu bikoresho bya polyurethane bibonerana.

Uburyo Imyitozo yo Gutunganya Amagufwa Ishobora Gushyira mu Bikorwa Ingamba zo Guhitamo Amabara

Gushyira hamwe ingamba zihamye zo guhitamo amabara mu buvuzi bw'amenyo bisaba ibirenze kugura gusa ubwoko butandukanye bw'amabara ya elastomeric ligatures. Bisaba uburyo buhamye bwo gukora akazi, gucunga ibikoresho, no kuvugana n'abarwayi. Hatabayeho uburyo bworoshye bwo guhitamo amabara, guhitamo amabara bishobora kubangamira ibikorwa byo ku ntebe, bigatwara igihe kinini mu buvuzi.

Ibara ry’amabara 20 kugeza kuri 30 ricunzwe neza ritwara ikiguzi gito cyane kuri buri murwayi—akenshi kiri munsi ya $0.15 kugira ngo ushyireho ligature mu kanwa kose—ariko bisaba kugenzura neza ububiko kugira ngo ibikoresho bikore neza. Ibikoresho bya polyurethane bigira ingaruka ku bidukikije, kandi kubika nabi bishobora gutuma ingufu zigabanuka mbere y’uko elasitiki ishyirwa mu kanwa k’umurwayi.

Uburyo bwo gukora protocole yo guhitamo amabara

Kugira ngo hirindwe ko guhitamo amabara byatwara umwanya w'agaciro mu ntebe, imikorere igomba guhuza inzira yo gufata ibyemezo hakiri kare mu mikorere y'abarwayi. Amavuriro menshi akomeye akoresha porogaramu zikoresha ikoranabuhanga zo gutoranya amabara ku ma tableti ari mu cyumba cyo gutegereza, bigatuma ingimbi zishobora kwibonera no guhitamo amabara yazo mbere yo kwicara ku ntebe y'amenyo. Iyi mpinduka yoroshye y'ubuyobozi ishobora kuzigama iminota 3 kugeza kuri 5 kuri gahunda yo guhindura imiterere y'imyanya.

Ubundi buryo, abaganga bashobora gukoresha "uruziga rw'amabara" ku meza yo koroshya urubyaro cyangwa aho bakirira abantu. Mu gihe umufasha w'abaganga b'amenyo azaba yiteguye gukuraho insinga, umurwayi aba yamaze guhitamo. Iyi gahunda igenzura ko inyungu mu myitwarire yo guhitamo amabara zigerwaho hatabayeho gutakaza imikorere myiza ya buri munsi y'ivuriro.

Ni iyihe itumanaho rikora neza ku rubyiruko n'ababyeyi?

Itumanaho ryiza rihindura guhitamo amabara ya elastike y'amabara kuva ku gukunda ubwiza gusa kugera ku masezerano y'imyitwarire. Abaganga n'abakozi bagomba gushyira mu bikorwa itangwa rya elastike y'amabara atandukanye nk'ubufatanye. Inyandiko isanzwe ikubiyemo kubwira umwangavu uti: “Ushinzwe guhitamo amabara kugira ngo inseko yawe isa neza, ariko mu yandi magambo, ugomba kuyambara amasaha 22 ku munsi kugira ngo ubuvuzi bugende neza.”

Gushyira ababyeyi mu bikorwa iki kiganiro na byo ni ingenzi cyane. Ababyeyi bakunze kugira umutwaro w’amafaranga wo kumara igihe kirekire bavurwa bitewe no kutubahiriza amategeko. Mu kwigisha ababyeyi uburyo amabara meza akora nk'ikimenyetso cy'uko umwana wabo yambaye imikandara yabigenewe—bibafasha kubona byoroshye niba umwana wabo yambaye imikandara yabigenewe—iki gikorwa gisaba umubyeyi kuba umugenzuzi ukora mu bijyanye no kubahiriza amategeko.

Uburyo ububiko n'igenzura ry'ubuziranenge bigira ingaruka ku buryo ibintu bihora bihinduka

Kugira ngo habeho ubwoko butandukanye bw'amabara ya elastomeric bisaba kugenzura neza ububiko. Elastomeric za orthodontic zifite igihe ntarengwa cyo kuzibika, akenshi zikaba hagati y'amezi 18 na 24, nyuma y'aho imiyoboro ya polyurethane itangira guhuza nabi, bigatuma icika intege kandi idashobora gutanga imbaraga zidasanzwe. Imyitozo igomba gushyira mu bikorwa sisitemu yo kubika ibikoresho bya mbere (First-In, First-Out) kugira ngo igabanye igihe cyo kurangira kw'ibikoresho.

Byongeye kandi,kugenzura ubuziranenge bigera no ku buryo bwo kubikaIbikoresho bya elastomeric bikunze kwangirika cyane ku rumuri rwa ultraviolet (UV) ndetse n'ihindagurika ry'ubushyuhe rikabije. Ibicuruzwa bigomba kubikwa mu bikoresho bitagaragara cyangwa mu bubiko bwijimye, kure y'izuba ryinshi n'ubushyuhe bwa autoclave, kugira ngo imiterere ya polymer ikomeze kuba myiza kandi irusheho gukomera.

Uburyo bwo gupima niba amabara akozwe mu buryo bwa elastic akwiye gutangwa

Kugira ngo habeho impamvu yo gukoresha ibikoresho mu gucunga urutonde runini rw'amabara akozwe muri elastomerike, abaganga b'inzobere mu by'imiti bagomba gusuzuma inyungu ku ishoramari (ROI) binyuze mu bipimo by'ubuvuzi n'imikorere. Nubwo ikiguzi cy'ibanze cy'amabara n'imigozi ari gito, agaciro nyakuri k'ubu buryo bwo kuvura gapimwa n'ingaruka zabwo ku mikorere myiza y'ubuvuzi no kugumana umurwayi.

Mu gukurikirana ku buryo bunoze ibipimo by'uko amategeko akurikizwa,

Ibintu by'ingenzi byakunzwe
