The limaoneka lokongola la Spee - ndi chiyani ichi?

Kodi limaoneka lokongola la Spee. Kuti tiyankhe funso limeneli, tiyenera kupeza zonse za occlusion.

occlusion ndi chiyani?

Occlusion kuitana kulankhulana ya m'munsi ndi zibwano chapamwamba. Chikhulupiriro chamakono akuti zikuphatikizapo mogwirizana wa kutafuna minofu, mano, temporomandibular olowa kukanika, ndipo ntchito. The occlusal padziko mano lachibadwa gawo la pamwamba dzino kuchokera pamwamba mpaka kuya tubercle malo chapakati fissure. Iwo amakhala ndi mbali anatomical amene chibadwa ndinazolowera ntchito ya kutafuna chakudya.

Zochitika za padziko occlusal

Zinthu zotsatirazi muli pa kali occlusal: gawo lapansi hillocks nsonga awo, ndi zina chapakati fissure, malo otsetsereka, maenje malire muzingochita tebulo occlusal, kuwala odzigudubuza tokhala triangular, zitunda. Ndi fissure chapakati akukumana ndiziwunda mkati dzino cusps.

Lingaliro la gulu la ojambula amaperekedwa mizere mano pano pa mbali kugwira ntchito mu buccal cusps premolar, mano canine, mano molar kuphatikizapo nsagwada chapamwamba ndipo m'munsi. Kugwirizanitsa kumatha mbali occlusal ojambula, ndi pa yemweyo maxillary timabamputimabampu palatal ali ndi tsaya mandibular. Pamene mandible chinapitiriza kukwaniritsidwa, mesial buccal cusps wa otsetsereka apansi verhnezubnym wapotalikira otsetsereka Wopanda, ndi stingrays lingual cusps wapotalikira mbali chapamwamba mano Wopanda pa malo otsetsereka mesial mbali mano m'munsi.

Posankha amaika protrusive mandibular kayendedwe khalidwe anapanga pa PAD erasure verhnezubnyh timabamputimabampu ndiziwunda wapotalikira ndi ndiziwunda nizhnezubnyh Bugorkova mesial pamwamba molimba minofu pa m'munsi ndi chapamwamba incisors vestibular palatal pamwamba.

ndi limaoneka lokongola la Spee ndi Wilson chiyani? Pa lino.

Kodi kutafuna chakudya?

Pamene akuchita kayendedwe lateral la nsagwada m'munsi, lakunja mbali otsetsereka buccal cusps a m'munsi mano Wopanda kumbali ntchito ya otsetsereka lamkati la chapamwamba mano buccal, ndi ndiziwunda mkati nizhnezubnyh cusps lingual Wopanda pa ndiziwunda akunja chapamwamba palatal cusps. Pakubwera kukhazikitsidwa kwa dzina chomwecho funsani cusps buccal wa premolars ndi molars.

Canines amateteza minofu mwakhama ndi periodontal mano zapambuyo ku kupanikizika kwambiri pa kutafuna, chotero, pamene zotsimikizira milatho kusamalira kwambiri ndi olimba a prosthesis kupewa choipa periodontal.

Pamene ojambula canines symmetrical mu occlusions lateral yunifolomu katundu amaperekedwa pa TMJ, mano, kutafuna minofu ndi periodontium pa kutafuna. Zonsezi ndi imapereka limaoneka lokongola la Spee.

Pa palatal (occlusal) pamalo a incisors chapamwamba ndipo canines ndi mesial ndi wapotalikira mbali m'mphepete 2 wodzigudubuza polumikiza tubercle mano wachitatu kunsi kwa dzino.

Pakati pa izi ndi m'ma cusp ya akadaulo ili palatal apakatikati wodzigudubuza ndi grooves mbali zonse. Mano tubercle otchedwa mbali yaikulu kwambiri ya dzino, malo ojambula occlusal chichitike. Izi kupindika lalikulu la kubwezera limaoneka lokongola la Spee.

Palatine hillocks chapamwamba ndipo m'munsi mano zapambuyo buccal kuitana Buku monga chakudya onongani ndi kudziwa chikhalidwe cha kayendedwe mwa munda wa occluding ndi mandible, kuphatikizapo kusokonekera kutulutsa mphamvu masticatory kuti katundu zofunika kutenga mano kutafuna olamulira.

Chifukwa occlusion zokhotakhota?

Buccal hillocks chapamwamba ndipo m'munsi mano zapambuyo lingual otchedwa zoteteza popanda thandizo. Iwo pang'ono pokhudzana ndi muzikangana mu occlusion chapakati kapena, monga ena olemba, kukhudzana ngati alibe. Izi Knobs ntchito ikuchitika magawano chakudya ndi chilengedwe pa muzikangana awo otsetsereka a padziko kutsetsereka, zoteteza masaya ndi lilime pa kutafuna iwo kutenga pakati mano. Kukulitsa Spee pamapindikira zofunika kutafuna yachibadwa chakudya.

Osati ziwirizi (mfundo) yunifolomu, ojambula angapo otsutsana mano ndi yabwino kwambiri mawonekedwe occlusions kutafuna ntchito zolengedwa mu mawerengeredwe wa occlusion pamwamba. Pankhaniyi, nkotheka kuchita processing chakudya cha kugwirizana aliyense. Kutafuna yogawa kuthamanga amapezeka kudutsa wamsuwachi olamulira, ndi katundu osachepera pa periodontium, ndipo pa ojambula yaing'ono mfundo amachepetsa erasure ndege masticatory. Contact amalenga fissures ndi hillocks bata m'munsi nsagwada ndi chapakati occlusion mfundo munsi mu mtondo, kuphatikizapo vuto lililonse kwa kusuntha nsagwada m'munsi mwa munda occlusal. Izi zimabweretsa limaoneka lokongola la Spee (chithunzi pansipa, mukhoza kuona chifaniziro chake zojambula).

Ngati mano zikusowa?

Popeza mano, imfa i.e. a padziko occlusal, kuti apeze chinthucho ndi occlusal ndege kudutsa mfundo atatu: mfundo yachiwiri molars m'munsi (awo cusps wapotalikira-buccal) ndi incisal mfundo. m'ndegemu ntchito kukhazikitsa chitsanzo cha mandible mu articulator ndi, mwachitsanzo, kudzera balancer lapansi.

Occlusal pamwamba mano ndege yopingasa si uli, ndipamene pamapindikira sagittal malangizo: a concave ndi otukukira kunja kwa pansi pa nsagwada chapamwamba. Chotero pamapindikira ndi amatchedwa limaoneka lokongola la Spee kapena occlusal sagittal limaoneka lokongola. Iye ali mbali ya bwalo lake pakati lili pafupifupi pakati pa kanjira lapansi.

The zambiri lodziwika Spee pamapindikira?

Komanso, monga Spee, ofufuza ndi Tsatani, occlusal pamapindikira kwathunthu kumatanthauza articular njira, chifukwa, pamodzi ndi pamapindikira wa ya mano popangidwa ndi utali wozungulira umodzi, ndi moyenera, mano ndi articular mutu Wopanda pa circumference wina kutsogolo ndi steeper otsetsereka a articular njira, kwambiri yunifolomu occlusal concave limaoneka lokongola. maganizo amenewo ndi asayansi anakumana mfundo zambiri. asayansi ena amanena kuti occlusal pamapindikira sitinganene kuti ndi gawo la bwalo. Mu kupitiriza kwa pamapindikira sagittal wa Spee zambiri amapita pamwamba kapena pansi pa njira limodzi ndi malo ake sali mu zitsulo diso.

Chifukwa pali kufunika mu pamapindikira sagittal wa occlusion?

Pamene mandibular patsogolo kayendedwe Vered ndi kutsika Pepala olowa mutu pa otsetsereka a articular tubercle. Choncho, nsagwada m'munsi ndi adatchithisira pansi (kumbuyo gawo) ndi ndipamene dehiscence m'dera zapambuyo pakati pa mizere ya mano. Contact tokhala ofananira mano zotheka ngati mzere sagittal kuwataya kutafuna pamwamba pa mano. Potsatira chiphunzitso ichi, wotchedwa occlusal mwachindunji malipilo limaoneka lokongola.

utali wozungulira anatsimikiza mtima 5,8-21,2 masentimita, kufunika pafupifupi -. 6.5-8.5 masentimita kuya mfundo occlusal pamapindikira - mesial tubercle wa molar m'munsi choyamba.

Nkhaniyi anafotokoza limaoneka lokongola la Spee.
