Impembelelo yeBracket Slot Geometry kwi-Force Delivery
Uyilo lweSlot oluyiSkwere noluyiRectangular kunye neTorque Expression
Isibiyeli I-slot geometry ilawula kakhulu indlela i-torque ebonakala ngayo. I-Torque ibhekisa kwintshukumo yokujikeleza kwezinyo ejikeleze i-axis yalo ende. Iingcali ze-Orthodontists zisebenzisa ikakhulu uyilo lwe-slot ezimbini: isikwere kunye ne-rectangular. I-Square slots, njenge-0.022 x 0.022 intshi, zibonelela ngolawulo olulinganiselweyo kwi-torque. Zibonelela "ngokudlala" okungakumbi okanye ukuvuleka phakathi kwe-archwire kunye neendonga ze-slot. Oku kudlala okwandisiweyo kuvumela inkululeko enkulu yokujikeleza kwe-archwire ngaphakathi kwe-slot. Ngenxa yoko, i-bracket idlulisela i-torque engachanekanga kangako kwizinyo.
Izithuba ezizinxantathu, ezifana ne-0.018 x 0.025 intshi okanye i-0.022 x 0.028 intshi, zibonelela ngolawulo oluphezulu lwe-torque. Ubume bazo obude bunciphisa ukudlala phakathi kwe-archwire kunye ne-slot. Oku kuhambelana okuqinileyo kuqinisekisa ukudluliselwa ngokuthe ngqo kwamandla ajikelezayo ukusuka kwi-archwire ukuya kwi-bracket. Ngenxa yoko, izithuba ezizinxantathu zenza ukuba i-torque ibonakale ngokuchanekileyo nangokuqikelelwayo. Oku kuchaneka kubalulekile ekufezekiseni indawo efanelekileyo yeengcambu kunye nokulungelelaniswa kwamazinyo ngokubanzi.
Impembelelo yobukhulu beSlot kwiSasazo soXinzelelo
Ubukhulu obuchanekileyo besithuba sebracket buchaphazela ngokuthe ngqo ukusasazwa koxinzelelo. Xa i-archwire ibamba isithuba, ifaka amandla kwiindonga zebracket. Ububanzi nobunzulu besithuba buchaza indlela la mandla asasazwa ngayo kwizinto zebracket. Isithuba esinokunyamezelana okuqinileyo, oko kuthetha ukuba akukho sithuba sininzi esijikeleze i-archwire, sigxila uxinzelelo kakhulu kwiindawo zoqhagamshelwano. Oku kunokukhokelela kwiingcinezelo eziphezulu ngaphakathi komzimba webracket nakwi-interface yebracket-tooth.
Ngokwahlukileyo koko, indawo yokudlala enkulu isasaza amandla kwindawo enkulu, kodwa ingathanga ngqo. Oku kunciphisa uxinzelelo loxinzelelo lwendawo. Nangona kunjalo, kunciphisa nokusebenza kakuhle kokudluliselwa kwamandla. Iinjineli kufuneka zilinganisele ezi zinto. Ubukhulu bendawo efanelekileyo bujolise ekusasazeni uxinzelelo ngokulinganayo. Oku kuthintela ukudinwa kwezinto kwi-bracket kwaye kunciphisa uxinzelelo olungafunekiyo kwizinyo nakwithambo elijikelezileyo.

Ngaphezu koko, ukubonakaliswa kwe-torque echanekileyo, enikwe amandla yi-rectangular slots ezicwangcisiweyo kakuhle, kunciphisa isidingo sokugoba okuhlawulelwayo kwi-archwire. Oku kwenza kube lula indlela yonyango. Kukwanciphisa ixesha lonyango ngokubanzi. Ukuhanjiswa kwamandla ngokufanelekileyo kuqinisekisa ukuba iintshukumo zamazinyo ezifunwayo zenzeka ngendlela eqikelelweyo. Oku kunciphisa iziphumo ebezingalindelekanga, ezifana nokufunxwa kweengcambu okanye ukulahleka kwe-anchorage. Ekugqibeleni, uyilo lwe-slot oluphezulu lunegalelo ekukhawulezisweni, ekuqikelelekeni ngakumbi, nasekukhululekeni ngakumbi.unyango lwamazinyo iziphumo kwizigulane.
Ukuhlalutya ukusebenzisana kwe-Archwire kunye neeBrackets ze-Orthodontic Self Ligating
Iinkqubo zokuQhaqha kunye nokuBinding kwiSlot-Archwire Systems
Ukungqubana nokubopha kuzisa imingeni ebalulekileyo kunyango lwamazinyo. Zithintela ukushukuma kwamazinyo okusebenzayo. Ukungqubana kwenzeka xa ucingo lwe-arch lutyibilika eludongeni lwe-bracket slot. Olu xhathiso lunciphisa amandla asebenzayo adluliselwa emazinyweni. Ukungqubana kwenzeka xa ucingo lwe-arch ludibana nemiphetho ye-slot. Olu qhagamshelo luthintela intshukumo ekhululekileyo. Zombini ezi ziganeko zandisa ixesha lonyango. Izibiyeli zemveli zihlala zibonisa ukungqubana okuphezulu. Ii-Ligatures, ezisetyenziselwa ukuqinisa ucingo lwe-arch, zilucinezela kwi-slot. Oku kwandisa ukumelana kokungqubana.
Iibrakethi ze-Orthodontic Self Ligating zijolise ekunciphiseni ezi ngxaki. Zine-clip okanye ucango olwakhelwe ngaphakathi. Le ndlela ikhusela i-archwire ngaphandle kwe-ligatures zangaphandle. Olu yilo lunciphisa kakhulu ukungqubana. Ivumela i-archwire ukuba ityibilike ngokukhululekileyo. Ukungqubana okuncitshisiweyo kukhokelela ekuhanjisweni kwamandla rhoqo. Ikwakhuthaza ukuhamba kwamazinyo ngokukhawuleza. Uhlalutyo lweFinite Element (FEA) lunceda ukulinganisa la mandla okungqubana. Ivumela iinjineli ukubalungiselela uyilo lwezibiyeli.Olu phuculo luphucula ukusebenza kakuhle kokunyakaza kwamazinyo.
Ii-Angles zokudlala kunye nokuzibandakanya kwiintlobo ezahlukeneyo zeBracket
"Ukudlala" kubhekisa kwindawo ephakathi kwe-archwire kunye ne-bracket slot. Ivumela inkululeko ethile yokujikeleza kwe-archwire ngaphakathi kwi-slot. Ii-engile zokuzibandakanya zichaza i-engile apho i-archwire iqhagamshelana khona neendonga ze-slot. Ezi engile zibalulekile ekudlulisweni kwamandla ngokuchanekileyo. Ii-brackets eziqhelekileyo, kunye nee-ligatures zazo, zihlala zinemidlalo eyahlukeneyo. I-ligature inokucinezela i-archwire ngokungahambelaniyo. Oku kudala ii-engile zokuzibandakanya ezingalindelekanga.
Iibrakethi ze-Orthodontic Self Ligating zibonelela ngokudlala okuqhubekekayo. Indlela yazo yokuzibopha igcina ukulingana okuchanekileyo. Oku kukhokelela kwii-engile zokuzibandakanya ezinokuqikelelwa ngakumbi. Ukudlala okuncinci kuvumela ulawulo olungcono lwe-torque. Kuqinisekisa ukudluliselwa kwamandla ngokuthe ngqo ukusuka kwi-archwire ukuya kwizinyo. Ukudlala okukhulu kunokukhokelela ekubetheni kwamazinyo okungafunekiyo. Kukwanciphisa ukusebenza kakuhle kokubonakaliswa kwe-torque. Iimodeli ze-FEA zilinganisa ngokuchanekileyo olu nxibelelwano.

Iipropati zezinto kunye nendima yazo ekudlulisweni kwamandla
Iimpawu zezinto zebracket kunye ne-archwire zichaphazela kakhulu ukudluliselwa kwamandla. Iibracket zihlala zisebenzisa intsimbi engagqwaliyo okanye i-ceramics. Intsimbi engagqwaliyo inika amandla aphezulu kunye nokungqubana okuphantsi. Iibracket zeseramikhi zintle kodwa zinokuba buthathaka ngakumbi. Zikwanokuthanda ukuba nee-coefficients eziphezulu zokungqubana. Ii-archwires ziza ngezinto ezahlukeneyo. Iintambo zeNickel-titanium (NiTi) zibonelela nge-superelasticity kunye nememori yokuma. Iintambo zentsimbi engagqwaliyo zibonelela ngokuqina okuphezulu. Iintambo zeBeta-titanium zibonelela ngeempawu eziphakathi.
Ukusebenzisana kwezi zinto kubaluleke kakhulu. Umphezulu we-archwire ogudileyo unciphisa ukungqubana. Umphezulu wesloti ocoliweyo unciphisa ukumelana. Ukuqina kwe-archwire kulawula ubukhulu bamandla asetyenziswayo. Ubunzima bezinto ezikwi-bracket buchaphazela ukuguguleka ngokuhamba kwexesha. I-FEA ifaka ezi mpawu zezinto kwiimodeli zayo. Ilinganisa impembelelo yazo edibeneyo ekuhanjisweni kwamandla. Oku kuvumela ukukhethwa kweendibaniselwano zezinto ezifanelekileyo. Iqinisekisa ukuhamba kwamazinyo okusebenzayo nokulawulwayo kulo lonke unyango.
Indlela yokwenza ubunjineli be-slot ye-bracket efanelekileyo
Ukudala iiModeli zeFEA zoHlalutyo lweBracket Slot
Iinjineli ziqala ngokwakha iimodeli ze-3D ezichanekileyoizibiyeli ze-orthodontickunye nee-archwires. Basebenzisa isoftware ye-CAD ekhethekileyo kulo msebenzi. Iimodeli zimela ngokuchanekileyo i-geometry ye-bracket slot, kubandakanya ubukhulu bayo obuchanekileyo kunye nokugoba kwayo. Okulandelayo, iinjineli zahlula ezi geometries zintsonkothileyo zibe zizinto ezininzi ezincinci, ezidibeneyo. Le nkqubo ibizwa ngokuba yi-meshing. I-mesh ecolekileyo inika ukuchaneka okukhulu kwiziphumo zokulinganisa. Olu hlobo lomodeli oluneenkcukacha lwakha isiseko se-FEA ethembekileyo.
Ukusebenzisa Imiqathango Yemida kunye Nokulinganisa Imithwalo Ye-Orthodontic
Abaphandi emva koko basebenzisa iimeko ezithile zomda kwiimodeli ze-FEA. Ezi meko zilinganisa imeko yokwenyani yomlomo. Zilungisa iindawo ezithile zomzekelo, njengesiseko sebracket esinamathele kwizinyo. Iinjineli zikwalinganisa amandla asetyenziswa yi-archwire kwi-bracket slot.
