Ko te ānau o Spee - he aha te mea tenei?

He aha te mea te ānau o Spee. Hei whakahoki i tēnei pātai, e ti'a ia tatou ki te kitea i roto i te katoa e pā ana ki occlusion.

He aha te mea occlusion?

karanga Occlusion tetahi whakapā o te raro me kauae runga. Ko te ariā hou o te wā ngā te pāhekoheko o te ngaungau uaua, niho, temporomandibular pōrearea tahi, me ngā mahi. whakaaro te mata occlusal o te niho tūturu te wahi o te mata niho i te runga ki nga wahi tubercle moko o pokapū hohonu. Kei te āhuatanga i te reira e te āhuatanga kikokiko e e ira taunga ki te mahi o ngaungau kai.

Elements o te mata occlusal

Ko runga i te papa occlusal te huānga e whai ake nei: Tïpako hillocks ratou tihi, ka rohe ki atu pokapū moko, Aharoto, rua rāhui te tepu occlusal, hihi awa fepulopulasi tapatoru, tupuke. E te moko pokapū anga rōnaki ā cusps niho.

whakaratohia te ariā o te rōpū o hoapā te rarangi o niho reira i te taha mahi i roto i te pūrākau cusps buccal, niho rei, niho titiwha tae atu kauae o runga, me te raro. Whärite faaore hoapā occlusal taha, a i te kotahi tubercles palatal maxillary e ki te paparinga mandibular. A, no te neke te kauwae whakamua, mesial cusps buccal o nga titahatanga o raro o verhnezubnym Aharoto distal kiriata, me te reo Stingrays cusps taha distal niho runga kiriata i runga i te titahatanga taha mesial o nga niho o raro.

A, no te hanga nui protrusive āhuatanga kaupapa mandibular e hanga e runga papa erasure verhnezubnyh tubercles haupuria distal me nga puke nizhnezubnyh Bugorkova mesial mata kiko pakeke i runga i te incisors runga mata palatal vestibular raro me.

He aha te mea te ānau o Spee me Wilson? I runga i tenei i muri mai.

Kia pehea te te ngaungau kai?

A, no te raveraa i nekehanga lateral o te kauae raro, nga titahatanga taha waho cusps buccal o te raro niho kiriata i runga i te taha mahi o nga titahatanga i roto o nga niho buccal runga, me rōnaki ā nizhnezubnyh paheke cusps reo i runga i rōnaki waho cusps palatal runga. Mai te whakatūnga o te taua ingoa whakapā i te cusps buccal o premolars me molars.

whakarato canines tiaki mo te kiko pakeke, me te periodontal niho posterior i rawa nui te ahotea i roto i ngaungau, a reira, ka utu hokohoko piriti aro ngā ki te stabilization o te prosthesis ki te karo i whara periodontal.

A, no te whakaratohia hoapā canines hangarite i roto i occlusions lateral kawenga kākahu kei i runga i te TMJ, niho, ngaungau uaua me periodontium i roto i ngaungau. whakarato tenei katoa me te ānau o Spee.

I palatal (occlusal) papa o nga incisors runga me canines ki te mata taha mesial me distal 2 he takai honotanga tubercle niho i roto i te toru o raro o te niho.

I waenganui i tenei me nga waenganui-cusp o te mata whakairo e tū palatal awaawa takai he tau waenga i runga i ngā taha e rua. ka karanga tubercle Dental te wahi tino kōhure o te niho, he wahi i reira tango hoapā occlusal wahi. Ko te curvature nui o te ānau utu o Spee tenei.

Palatine hillocks runga me raro niho posterior tohutoro karanga buccal rite hua ratou kai kuru me te whakatau i te āhua o nekehanga i roto i te mara o occluding te kauwae, tae atu tohatoha anō hua ope masticatory kia e tango i te kawenga taketake tuaka ngangau niho.

Aha ānau occlusion?

hillocks Buccal o runga me raro niho posterior reo i huaina tiaki kahore tautoko. E paku ratou i roto i te whakapā atu ki te te raveraa ra i roto i te occlusion pokapū ranei, rite ki te tahi mau kaituhi, e kore e taua whakapā i. kawea ēnei puku mahi i roto i te wehenga kai me te hanga i runga i o ratou te raveraa ra Aharoto o te mata retireti, e tiaki nga paparinga, me te arero i roto i ngaungau ratou i whiwhi i waenganui i te niho. Faahohonuraa ānau Spee tika mō te ngangau noa o te kai.

Ehara i huinga (ira) kākahu, hoapā maha hoariri niho he occlusions puka tino pai fakateka mahi hanga nei i roto i te whakatauira o mata occlusion. I roto i tenei take, ki te taea te kawe i roto i tukatuka o kai o tetahi ōritetanga. Fakateka pēhanga tohatoha puta puta noa te tuaka paraihe, ki te kawenga iti i runga i te periodontium, me i hoapā wāhi iti heke erasure rererangi masticatory. hangaia e Whakapā matore me hillocks pūmautanga kauae raro ki te pepe occlusion parau tumu pokapū i roto i te kumete, tae atu kahore tutukitanga mō te neke i te kauae raro o te mara occlusal. whakarato ana tēnei i te ānau o Spee (i roto i te whakaahua i raro nei, ka taea e kite koe i tona kanohi schematic).

Ki te kei te ngaro niho?

I roto i te ngaro o nga niho, i.e. mate o te mata occlusal, ko te manureva occlusal haere i roto i ngā toru mo tona ora: ko te akitu tuarua molars raro (ratou cusps distal-buccal) me wāhi incisal. whakamahia tēnei rererangi te ki te whakatū i te tauira o te kauwae i te articulator, hei tauira, mā te balancer.

e kore te Occlusal mata o te niho i roto i te manureva whakapae roto, hanga ana e ia he aronga ānau sagittal: he kōpapa, me te ohu nei ki te raro mo te kauae runga. huaina te ānau taua ko te ānau o te Spee occlusal ānau sagittal ranei. Ko te wāhanga o te porowhita e kei āhua i te pokapū o te āmionga nei pokapū ia.

Ko te ānau Spee atu nui?

Ano, rite tonu Spee, kairangahau me te Practice, Kei te tino tautuhi occlusal ānau ara articular, mai reira, tahi ki te ānau o te huinga o niho i hanga e tetahi pūtoro, a i runga i, niho, me te upoko articular kiriata i runga i tetahi paenga mua me te poupou te taha o te articular ara, atu kākahu occlusal ānau hakoko. Taua whakapae i hanga e te pūtaiao tūpono maha whakahe. Ētahi atu kaipūtaiao tautohe e kore e taea te huaina occlusal ānau he tuhaa o te porowhita. I roto i te haere tonu o te ānau sagittal o Spee maha haere i runga ranei i raro i te ara tahi, a kahore he tona pokapū i roto i te turanga kanohi.

He aha i reira he he hiahia i roto i te ānau sagittal o occlusion?

A, no te haere iho mandibular kaupapa whakamua Vered me te pepa upoko tahi i runga i te taha o te tubercle articular. Nä, tuku iho te kauae raro te iho (hoki wahi) ka hanga dehiscence i roto i te rohe posterior i waenganui i nga rarangi o te niho. lateral fepulopulasi Whakapā niho taea anake i roto i te take o te rārangi sagittal tikanga fakateka mata o nga niho. I muri i tenei whakaako, ka karanga te occlusal ānau utu tika.

whakaritea te pūtoro 5,8-21,2 henimita, te uara toharite -. 6.5-8.5 cm hohonu ānau wāhi occlusal - tubercle mesial o te titiwha tuatahi raro.

Ko te tuhinga whakaahuatia i roto i te taipitopito ānau o Spee.
