Sisitemu yo kurinda inkombe
Imbaraga zo kuvura amenyo zigenzurwa n'ubuyobozi
Gabanya igihombo cyo guhagarara kw'imizigo
Gukomeza gutuza kw'umurongo wo hagati
IV. Ubuyobozi bwo Guhitamo Icyitegererezo
Ingano y'impeta y'icyitegererezo (mm) Agaciro k'imbaraga zikoreshwa (g) Ibimenyetso byiza Inzira yo gusimbuza
Indwara y'uruhu ikabije 0.8 80-120 Indwara y'uruhu ifata amenyo (periodontal disease) iminsi 2-3
Ubwoko busanzwe 1.0 150-200 Gufunga icyuho gisanzwe iminsi 4-5
Ubwoko bwa 1.2 bwongerewe 250-300 Gutandukanya molar/gukenera guhagarara cyane iminsi 7
V. Imiterere yihariye y'ikoreshwa
Gukosora gufungura no gufunga
Gufatana mu buryo buhagaze (hagati ya 6-6)
Huza hamwe n'ikirango cy'ubuyobozi gihagaze neza
Kanda muri 1-1.5mm buri kwezi
Guhindura umurongo wo hagati
Gufata ku ruhande rumwe bikomejwe
Igishushanyo mbonera cy'ingufu zidahuje
Ishobora gukosora 0.3-0.5mm mu cyumweru
Hafi y'icyuma gishyirwamo implant
Imbaraga zoroshye kandi zihoraho (<100g)
Urunigi rw'umupira rurwanya bagiteri
Irinde guhungabanya ishyirwa mu bikorwa rya osseointegration
VI. Ibipimo by'imikorere y'ubuvuzi
ingingo z'ingenzi zo gushyiraho
Koresha imashini yabugenewe kugira ngo urambure
Komeza urwego rwo kugabanya ubukana bwa 30-50% mbere yo kunanura
Irinde gupfundika inguni ikaze
Kugenzura ingufu
Agace k'amenyo y'imbere ≤150g
Agace k'inyuma ≤ 200g
Gupima buri gihe ibikoresho bipima imbaraga
Kwirinda ingorane
Uburibwe bw'ishinya (igipimo cy'ubwiyongere bw'indwara ni 15%)
Gukusanya plaque (gusukura buri munsi)
Umunaniro ukabije (gusimbuza buri gihe)
VII. Icyerekezo cy'udushya mu ikoranabuhanga
Ubwoko bw'igisubizo cy'ubwenge
Agaciro k'imbaraga zo guhindura ubushyuhe
Imikorere yo kwibuka ishusho
Uburyo bwo kuvura: kuvura amenyo mbere yo kubagwa amenyo
Ubwoko bw'imiti irekura buhoro buhoro
Uburyo bwo kwirinda caries irimo fluoride
Ubwoko bw'imiti igabanya ububabare n'uburibwe
Guteza imbere kuvugurura ingingo z'amenyo
Ubwoko bw'ibinyabuzima byangirika kandi bitagira ingaruka ku bidukikije
Ibyumweru 6 byo kwangirika kw'ibidukikije
Ifu y'ibishyimbo by'ibigori
Ibyuka bihumanya ikirere byagabanutseho 70%
VIII. Ibyifuzo by'abahanga mu gukoresha
"Iminyururu ya rubber ni 'umufasha utagaragara' w'abaganga b'amenyo. Inama:
Ikoreshwa rya mbere ry'ubwoko busanzwe
Reba uko imbaraga zangiritse buri minsi 3
Gukoresha hamwe mu manza zikomeye
"Gukorana na sisitemu yo kugenzura ikoranabuhanga"
– Komite Tekiniki y'Ishyirahamwe ry'Abaganga b'Amagufwa bo muri Aziya
Iminyururu y'amashanyarazi, ifite imiterere yihariye ya mekanike irabagirana, yuzuza inshingano idasubirwaho yo kugenzura imiterere itatu mu kuvura amenyo. Bitewe n'iterambere ry'ubumenyi bw'ibikoresho, umusaruro mushya w'ibicuruzwa, mu gihe bikomeza imikorere ya kera, urimo ugana ku bwenge n'imikorere, ukomeza gutanga inkunga yizewe yo kuvura amenyo neza. Guhitamo no gukoresha iminyururu ya rubber neza bishobora kongera imikorere myiza yo kuvura amenyo ku kigero kirenga 25%, ibi bikaba ari garanti y'ingenzi yo kugera ku buryo bwiza bwo kuziba.
