Haasi kungova mahwendefa, asi microprostheses inoshandiswa kugadzirisa chimiro uye ruvara rwemwemwemwemwe. Chigadziro chekugadzirira chinongoputira mberi nechokumusoro kwemazino.
Mhando yezvipfeko zviripo?
Kune marudzi maviri e microprosthesis mubvunzo, iyo yakarongwa inobva pane zvinhu zvekugadzira. Mitauro yeveneers:

Chiremba anovapa chimiro chekupedzisira mumuromo, mushure mekunyungudutsa tsvina yakawanda yeeamel. Izvi zvakasiyana-siyana zvevenaers zvinokurudzirwa kuiswa kuti zvivandudze mazino 1-2 mumutsara, nokuti anongopedza makore 3-5 chete.
Kana iwe uchida zvimwe zvakagadziriswa veneers pamazino epamberi, kana mukururamisa unoda nzvimbo yose inosemwerera, unofanirwa kusarudza nzira ye laboratori yekugadzira michina yakawanda.

Izvo zvinokonzerwa nezvipfeko zvakavezwa nepependi yakakosha, iyo inogonesa kuti ruvara rwavo runofanana nehutano hwemazino akasiyana-siyana akamira. Mukuwedzera, iyo nyanzvi-mazino anoramba achidzoka pamakeramiki akasiyana-siyana emhando yezvigadzirwa zvemaoko. Iyi ndiyo yakanakisisa veneers isati yapfuura uye mushure memafirimu inoratidza kuti aya majeri anotarisa zvakasikwa uye panguva imwechete anopa kururamiswa kunoratidzirwa kweiyo dentition. Iyo inogara yakasimba (hupenyu huri pakati pemakore gumi nemashanu) uye yakasimba, isina kufanana nesimbi inonzi microprostheses, haishanduki ruvara rwepakutanga.
Hollywood Laminates
