Ingano z'insinga zo mu bwoko bwa orthodontic zisobanurwa ku batangira

Intangiriro

Guhitamo ingano ikwiye y'insinga z'amenyo bigira ingaruka nyinshi kuruta gushyira mu mwanya w'insinga; bigena imbaraga zitangwa, uburyo amenyo agenda neza, n'uburyo ubuvuzi bumeze neza. Ku batangira, imibare n'ibice bikoreshwa mu gusobanura insinga z'amenyo bishobora gusa n'aho ari tekiniki, ariko bikurikiza ishingiro rifatika rijyanye n'intambwe zo kuvura no kugenzura. Iyi nkuru isobanura icyo ingano isanzwe y'insinga bivuze, uburyo zifitanye isano n'ingano z'insinga, n'impamvu itandukaniro rito mu bunini rishobora guhindura ubworoherane, gukomera, no kugenda. Amaherezo, uzaba ufite ishingiro risobanutse ryo gusoma ingano z'insinga no gusobanukirwa uruhare rwazo mu kwita ku nsinga z'amenyo.

Impamvu ingano y'insinga zo mu bwoko bwa orthodontic ari ingenzi

Guhitamo ingano z'insinga zo mu bwoko bwa orthodontique ni ikintu cy'ibanze cyagahunda yo kuvura indwara za biomechanicalInsinga zose zishyirwa mu mwanya w’icyuma gifunga amenyo zikora nk'umuyoboro ufasha amenyo kugenda neza, bigatuma ingufu za elastic zibikwa zihinduka imbaraga z’icyerekezo. Gusobanukirwa imiterere y’izi nsinga si ikibazo cyo gucunga ububiko gusa, ahubwo ni ngombwa cyane mu buvuzi, bikaba ari ngombwa kugira ngo ubuvuzi bw’amenyo bugerweho mu mutekano, umuvuduko, n’intsinzi.

Ubunini bw'insinga butuma imipaka y'umubiri w'umutsi w'amenyo yubahirizwa. Iyo umutsi w'amenyo ufashwe, ushyiraho igitutu gihoraho gituma amagufwa avugururwa. Kugira ngo amenyo agende neza mu buryo bw'umubiri, ubusanzwe bisaba imbaraga zoroheje kandi zihoraho hagati ya garama 20 na 150 (zitanga hafi 50 kugeza 100 kPa y'umuvuduko w'imitsi mu mutsi w'amenyo y'amenyo), bitewe n'iryinyo runaka n'uburyo rigomba kugenda. Gukoresha ingano zitari zo z'insinga bishobora kurenga iyi mibare, bigatera ingaruka mbi nko kuzura imizi, kubabara kw'umurwayi, cyangwa gutakaza ubushobozi bwo guhagarara.

Kugenzura gutanga no kuvura ku ngufu

Isano iri hagati y'ingano z'insinga n'ingufu zitangwa igengwa n'amahame y'ubukanishi bw'imirasire. Ubukana bw'insinga y'amenyo, bityo imbaraga itanga, ziyongera cyane uko zingana. Urugero, kongera umurambararo w'insinga izengurutse kuva kuri santimetero 0.014 kugeza kuri santimetero 0.016 byongera ubukana bwazo hafi 70%, mu gihe kongera umurambararo kabiri w'insinga izengurutse byongera ubukana bwazo ku gipimo cya 16. Iyi sano y'imibare ya kane y'imbaraga bivuze ko n'ubwiyongere bwa mikorosikopi mu murambararo w'insinga buhindura cyane imiterere y'imbaraga zikoreshwa ku menyo.

Byongeye kandi, uburebure bw'igice cy'insinga hagati y'udukingirizo (interbracket interference) bukorana n'ingano y'insinga kugira ngo hamenyekane uburyo bworoshye muri rusange. Insinga nini ntiziba zoroshye kandi zikoresha imbaraga nyinshi mu ntera ngufi. Kubwibyo, abaganga bagomba gupima neza ingano y'insinga kugira ngo zihuze n'icyiciro cyihariye cy'ubuvuzi, bakareba ko imbaraga zitangwa ziguma mu buryo bwiza bw'ibinyabuzima.

Ni nde ukeneye gusobanukirwa ibintu mu buryo bufatika?

Nubwo abaganga b'amenyo ari bo bafata ibyemezo by'ingenzi ku birebana n'ikoreshwa ry'ubuvuzi, gusobanukirwa neza ingano y'insinga bireba itsinda ryose ry'abaganga b'amenyo. Abafasha b'amenyo bishingikiriza kuri ubu bumenyi kugira ngo bamenye neza ibyo bakeneye mu buvuzi, bashyireho neza imiterere y'insinga, kandi birinde gutinda ku ntebe. Kumenya neza ingano y'insinga birinda ko insinga nini ishyirwa mu buryo butunguranye mu gihe cyo kuyihuza neza.

Byongeye kandi, abashinzwe amasoko n'inzobere mu bubiko bagomba gusobanukirwa uburyo bwo gupima ingano y'insinga kugira ngo bakomeze kugira ingano ikwiye y'imigabane. Ivuriro risanzwe rigomba gucunga ububiko bw'insinga 500 kugeza ku 1.000 butandukanye mu bikoresho, imiterere y'umugongo, n'ibice bito. Ingano nto zisanzwe zo gutumiza (MOQs) akenshi ziba hagati ya 10 na 50 kuri buri ngano, aho ikiguzi cy'ibikoresho gitandukanye bitewe n'ibikoresho (urugero, $0.50 kugeza $1.50 ku byuma bitazangiza, na $1.50 kugeza $5.00 kuri NiTi). Kumenya ibi bisobanuro bituma imikorere y'uruhererekane rw'ibikoresho igenda neza kandi bigatuma amavuriro ashobora gusuzuma abandi bakora ibikoresho neza. Kugira ngo bamenye neza ubuhanga busesuye ku batanga ibicuruzwa n'amahame y'ubuziranenge, abahanga bakunze kureba amakuru arambuye ku bikoresho.Ingano z'insinga zo mu bwoko bwa orthodontiquen'inkomoko y'inganda.

Uburyo insinga zo mu bwoko bwa orthodontic zigenwa

Insinga zo mu bwoko bwa orthodontique zipimwa ku isi hose hakoreshejwe uburyo bwa Imperial, cyane cyane mu gice cya santimetero 1000, kandi zigengwa n'amahame mpuzamahanga agenga inganda nka ISO 15841. Insinga yitwa "cumi na kane" mu mvugo isanzwe igaragaza umurambararo wa santimetero 0.014. Iri zina risanzwe ryemerera itumanaho rihoraho hagati y'abakora, abaganga, n'ibitabo by'ubushakashatsi ku isi yose.

Uburyo izi nsinga zishyirwa mu byiciro bushingiye ku bintu bitatu by'ingenzi: imiterere y'igice kimwe, ibipimo by'ingano, n'imiterere y'icyuma. Ibi bintu byose hamwe bigaragaza uburyo insinga zizahura n'umwanya w'urukuta n'imiterere ya mekanike izagaragaza mu gihe cyo kuvurwa. Imirongo y'urukuta ubwayo ikorwa mu buryo busanzwe, ahanini ikorwa mu bipimo bya santimetero 0.018 cyangwa santimetero 0.022.

Ingano z'uruziga ugereranije n'iz'urukiramende

Insinga zo mu bwoko bwa orthodontic zikorwa mu byiciro bitatu by'ingenziimiterere y'ibishushanyo mbonera by'ibice bitandukanye: uruziga, kare, n'urukiramende. Insinga zizengurutse zipimwa hakoreshejwe imiterere imwe y'umurambararo (urugero, santimetero 0.012, 0.016). Kubera ko zidafite inguni, insinga zizengurutse ntizishobora gufata inkuta z'urukiramende z'agace k'urukiramende kugira ngo zigenzure imiterere y'imizi y'amenyo (torque). Inshingano yazo y'ibanze ni ukunyura mu rukiramende byoroshye, zigahuza kandi zigahuza inkingi z'amenyo.

Insinga zifite impande ebyiri n'izifite impande ebyiri zikenera ingano ebyiri kugira ngo zimenyekane, zigaragaza uburebure n'ubujyakuzimu bw'insinga (urugero: santimetero 0.016 x santimetero 0.022). Umubare wa mbere muri rusange yerekeza ku gipimo gihagaze, mu gihe uwa kabiri yerekeza ku bujyakuzimu butambitse. Izi nsinga zagenewe kuzuza neza umwanya w'urukiramende, bigatuma umuganga ashobora gukoresha imbaraga no kugenzura aho umuzi w'amenyo uherereye mu mpande eshatu. Kugira ngo hirindwe ko insinga zifite impande eshatu zifatanye, ubusanzwe insinga zifite uburebure bw'imfuruka buri hagati ya santimetero 0.003 na santimetero 0.004.

Aloyi, ibice bihuriramo, n'imirongo ihuza inkingi

Uburyo insinga ikorana n'umwanya wo gufunga insinga n'aho ifunga insinga bizwi nka "gukina" cyangwa "clearance". Urugero, gushyira insinga ifite urukiramende rwa santimetero 0.019 x 0.025 mu mwanya wa santimetero 0.022 bisiga intera ihagaze ya santimetero 0.003, bingana na dogere 5 kugeza kuri 7 zo gufunga insinga. Ubu buryo bwo kwihanganira ibintu butuma habaho torque nziza. Ku rundi ruhande, gushyira insinga ya santimetero 0.016 x 0.022 mu mwanya umwe wa santimetero 0.022 bisiga santimetero 0.006 zo gufunga insinga (hafi dogere 12 kugeza kuri 15 zo gutakaza torque), bigabanya uburyo bwo kugenzura torque ariko bigatuma byoroha kuyinyeganyeza.

Imiterere y'insinga nayo igira uruhare runini. Ingano z'insinga zigomba gupimwa hakurikijwe ibikoresho byazo. Insinga ya Nickel-Titanium (NiTi) ya santimetero 0.016 izakora mu buryo butandukanye cyane n'insinga ya Stainless Steel ya santimetero 0.016, nubwo ifite umurambararo umwe. Imiterere y'icyuma igena uburyo insinga zikora, imbaraga zayo, n'uburyo ikora.

Imbonerahamwe igereranya ingano isanzwe

Kugira ngo barebe urutonde rw'insinga zitandukanye, abahanga bakoresha imbonerahamwe zisanzwe. Imbonerahamwe iri hepfo igaragaza ingano zisanzwe z'insinga, imiterere yazo mu bice bitandukanye, aho zihagarara, n'ikoreshwa risanzwe mu buvuzi hashingiwe kuri sisitemu isanzwe ya santimetero 0.022.

Uburyo bwo kugereranya ingano z'insinga ukurikije ibikoresho n'imikorere

Gusuzuma insinga zo mu bwoko bwa orthodontic bisaba gusesengura aho ingano y'umubiri n'ubumenyi bw'ibikoresho bihurira. Imikorere y'insinga iterwa n'ubukomere bwayo, gusubira inyuma kwayo, ubushobozi bwayo bwo gukora, nogushwanyagurika k'ubusoMu gukoresha neza ingano y'icyuma n'ibipimo byacyo, abaganga bashobora gusesengura neza imbaraga za biomechanical zikoreshwa ku menyo.

Ubuvuzi bw'imitsi bugezweho bushingiye cyane ku miryango itatu y'ingenzi ya alloy: Nickel-Titanium (NiTi), Stainless Steel (SS), na Beta-Titanium (ikunze kwitwa TMA). Buri gikoresho gifite imbaraga zidasanzwe zo gutanga umusaruro hamwe na moduli yoroshye. Ku bijyanye n'imiterere, Stainless Steel ifite moduli yoroshye cyane ya 160-180 GPa, Beta-Titanium iri kuri 60-80 GPa, naho NiTi yoroshye cyane kuri 30-40 GPa. Insinga za NiTi zishobora gukira kuva kuri 8% by'imiterere yazo zidahinduka burundu, mu gihe icyuma cyoroshye cya stainless cyangirika burundu iyo kigizwe n'imitsi irenga 1% kugeza kuri 2%.

Iyo ingano ntoya zikunze kuba nziza

Insinga nto z'umurambararo, ubusanzwe zigira hagati ya santimetero 0.012 na santimetero 0.016, zikoreshwa cyane mu ntangiriro z'ubuvuzi. Iyo amenyo yuzuye cyane cyangwa azungurutse cyane, insinga y'umurambararo igomba kunama cyane kugira ngo ifatanye n'udukingirizo tudahuye neza. Insinga nto za NiTi ni zo zikundwa cyane hano kuko zitanga ubushobozi bwo kuzenguruka cyane hamwe n'imbaraga nke kandi zihoraho (ubusanzwe garama 40 kugeza kuri 60 z'imbaraga kuri 2mm y'ihindagurika).

Gukoresha ingano nini mbere y’igihe muri ibi bihe byashyira igitutu kinini ku mitsi y’amenyo, bigatera ububabare, gucika kw’inyama, no gutinza inzira yo kwimuka kw’amenyo. Igice gito cy’amenyo gituma insinga iguma mu rugero rwayo rworoshye, ikayobora amenyo buhoro buhoro mu buryo bwa mbere.

Itandukaniro riri hagati ya NiTi, icyuma kidashonga, na beta-titanium

Ibyuma bitatu by'ingenzi bikora imirimo itandukanye ya biomechanical. Nickel-Titanium (NiTi) izwiho kwibuka imiterere yayo no kuba superelasticity. Ubwoko bw'ibinyabutabire bikoresha ubushyuhe bufite ubushyuhe bwa Austenitic ($A_f$) busanzwe buri hagati ya 27°C na 35°C. Bitanga imbaraga zihoraho ku buryo butandukanye bwo guhindagurika, bigatuma biba byiza cyane mu gihe amenyo y'amenyo adakora neza.

Icyuma Kidasanza (SS) kigereranya impande zinyuranye z'urusobe rw'ibintu. Gitanga ubukana bwinshi, ubushobozi bwo gukora neza, no gukururana guke k'ubuso. SS ni ibikoresho bikundwa cyane mu byiciro byo gukora no kurangiza, aho ubukana busabwa kugira ngo hafungwe ahantu ho gukurura cyangwa hagumane ubugari bw'insinga nta guhindagurika kw'insinga. Beta-Titanium (TMA) ihuza icyuho kiri hagati ya NiTi na SS. Ifite hafi 40% by'ubukana bw'icyuma kidasanza, itanga ubukana bw'imbaraga ziciriritse, ubushobozi bwo gukora neza, kandi ikagira ubukana buhagije bwo gushushanya ibice biri hagati.

Guhuza mu bijyanye no koroherana, imbaraga, no kugenzura

Guhitamo insinga nziza bikubiyemo guhuza hagati yo koroha, kugaragaza imbaraga, no gukururana. Insinga nto ya NiTi itanga ubushobozi bwo koroha cyane no gukururana guke, ariko nta bushobozi bwo kugenzura imbaraga. Ku rundi ruhande, insinga y'icyuma kitagira umugese ifite uburebure bwa santimetero 0.019 x 0.025 mu mwanya wa 0.022 itanga ubushobozi bwo kugenzura no kugaragaza imbaraga mu buryo budasanzwe, ariko irakomeye cyane kandi ikora uburyo bwo guhangana n'imbaraga mu gihe cyo gukururana (SS ifite ubushobozi bwo gukururana bungana na ~0.10–0.15, mu gihe TMA iri hejuru kuri ~0.25–0.35).

Abaganga bagomba kuringaniza ibi bintu hashingiwe ku ntego y’ubuvuzi yihutirwa. Niba intego ari ugutembera amenyo ku nsinga y’umugozi kugira ngo hazibwe icyuho, insinga ikomeye ntoya (urugero, 0.016 x 0.022 SS) niyo nziza kugira ngo igabanye kwihambira no gukururana. Niba intego ari ukuzunguza umuzi w’iryinyo rimwe mu mwanya waryo wa nyuma, insinga yuzuye ifite uburebure bwa mpandeshatu irakenewe kugira ngo ifatanye neza n’umuyoboro w’urukiramende.

Uburyo bwo guhitamo ingano ikwiye y'insinga yo gushushanya amenyo
