Zida zamakonzedwe zimatchedwa zinthu zosasuntha, zomwe zimagwiritsidwa ntchito kukonza zolakwira za kuluma kwaumunthu. Izi ndi zipangizo zovuta zomwe zimayikidwa mano ndi gulu lapadera, kenako zimagwirizanitsidwa ndi arc yomwe imakhala ndi "mawonekedwe", ndiko kuti, amabwerera ku mawonekedwe awo oyambirira panthawi yotentha. Kusintha kwa malo a mano m'kamwa kamvekedwe kamapindula pogwiritsa ntchito mphamvu yotsutsana ya chigoba chokhazikika. Zaka 15 zapitazo, ziboda zinali zatsopano komanso zodziwika, koma tsopano zosankha ndi zabwino - zitsulo kapena safiro - pa thumba lililonse.
Kodi nsalu za safiro zimawoneka bwanji?
Zoonadi, zoyamba zoyambirira zinali kutali ndi maonekedwe abwino. Anthu mamiliyoni ambiri sanayesere kukonza kuluma makamaka chifukwa cha makhalidwe abwino. Ana zikwizikwi apeza zovuta zambiri, akutha zaka zingapo zovuta zaka zachinyamata ndi zitsulo zazitsulo pamano awo. Koma, mwachisangalalo, ma mano amayamba patsogolo pokha podumpha ndi malire ndipo zamakono zamakono zingakhale zosawoneka m'mazinyo.
Zosangalatsa kwambiri za iwo ndizosowa za safiro. Kwa kupanga kwawo, makina amodzi a safiro amagwiritsidwa ntchito, motero, braces ali pafupifupi mwachangu ndi imperceptible pamene anakwera mano. Makhalidwe abwino a safironi ndi awa:
- iwo akuwonekera;
- Musadetse pamene mukudya zakudya kapena zakumwa;
- Pamwamba pamtunda simungapezeke chipika, chomwe chimachepetsa chiopsezo cha chitukuko cha mano opangidwa ndi ziboda (ngakhale, sizingakhale zofunikira kugwiritsa ntchito maswiti);
- mkulu kuvala kukana;
- musasokoneze ntchito ya kulankhula;
- musapangitse chisokonezo pakamwa;
- zochepetsetsa, zoyera bwino, m'mphepete mwazungulira;
- njira yodalirika yotsamira kwa enamel.
Zowoneka kwambiri ndizosafiyala za safiro ndi white arc. Kawirikawiri, makina opangidwa ndi zitsulo ndi amdima, zitsulo komanso, ngakhale ma sapulo opangidwa ndi safiro, amawonekera m'mazinyo. Koma orthodontics zamakono zimapanga mitsempha yapadera ndi chovala choyera chapamwamba, chomwe chimapangitsa kuti mapangidwewo asamamveke nthawi zonse.
Zoipa za braces
Zoonadi, palibe chokwanira, komanso nsalu za safiro, mwatsoka, nayenso. Kuchokera kwawo kwakukulu kwambiri ndiko kupunduka. Choncho, moyenera, ndibwino kusamala panthawi ya kudya komanso kusayesetsa mwakufuna kudya chakudya cholimba. Chotsatira chachiwiri chachidule cha makina oterewa ndi mtengo wawo wapamwamba. Tsoka, safirisi yoyera ya monocrystalline sichikondweretsa mtengo. Koma zopindulitsa zina zonse zidapitirirabe kupatula kuyika kwa nsalu za safiro.
Kodi ndi zofunikira zingati zomwe zimadetsa nkhawa aliyense amene asintha kuluma kwake? Sipangakhale yankho losavomerezeka, chirichonse chimadalira vuto la konkire. Koma kawirikawiri nthawi yodzikongoletsera mitundu
Kusiyanasiyana pakati pa ngongole za ceramic ndi safiro
Kusiyana koyamba pakati pa mawotchi awiri otchuka kwambiri maonekedwe. Zojambula za Ceramic ndi zoyera, ndi safiro, monga momwe tazionera kale - poyera. Ceramic imaphatikizapo polycrystalline aluminium oxide, yomwe imapereka mphamvu zowonjezereka kwambiri poyerekezera ndi safiro. Kusiyana kwakukulu ndi mtengo - miyala ya ceramic ndi yotchipa kusiyana ndi safire. Choncho nsalu za safiro zimakhala zokongola kwambiri pa mano opatulika, asanagwiritse ntchito, odwala ambiri amalimbikitsidwa kuti aziwongola mano . Ngongole ya ceramic idzawoneka bwino pamtambo uliwonse wa mthunzi, chifukwa mthunzi wa ceramics ukhoza kusinthidwa.
