The munyonga pamusoro Spee - chii ichi?

Chii munyonga pamusoro Spee. Kuti tipindure mubvunzo uyu, tinofanira kuziva zvose pamusoro occlusion.

Chii occlusion?

Occlusion danai kuzotaura repasi uye okumusoro shaya. The ano pfungwa rokuti kunosanganisira kubata pakati kutsenga tsandanyama, mazino, temporomandibular vadyi dysfunction, uye mabasa. The occlusal penyika yepanyama mazino ichaongororwa chikamu zino pemvura kubva kumusoro gobvu tubercle nzvimbo nechepakati kutsemuka uku. It kunoratidzwa anatomical zvinhu zviri majini kujairana mashandiro kutsenga zvokudya.

Zvenyaya occlusal pamusoro

Zvinotevera zvinhu dziri occlusal hukawanika: Substrate hillocks misoro yavo, uye zvakare nechepakati kutsemuka uku, neyemitenusirwa, Makomba Makaisa muganhu inorambidza kuti occlusal tafura, mwaranzi rollers mativi anorovera, anooneka zvikuru nemichinjiziri. Nechepakati kutsemuka uku rakatarira dzakawanda ramps zino cusps.

Pfungwa boka vokukurukura anopiwa mitsara kwemeno vaivapo nokushanda divi iri buccal cusps premolar, canine mazino, matadza nemazino kusanganisira okumusoro shaya. Kuwiriranisa anobvisa divi occlusal neshamwari, uye panguva imweyo maxillary palatal tubercles vari kurwisa mandibular dama. Kana mandible kunoita mberi, mesial buccal cusps repasi mujinga verhnezubnym distal nemitenusirwa yemasiraidhi, uye stingrays lingual cusps distal divi okumusoro mazino yemasiraidhi pamusoro egomo mesial divi rezasi kwemeno.

Pakuita kunyanyisa protrusive mandibular kufamba hunhu vari kuumbwa pamusoro ikanyanya erasure verhnezubnyh tubercles distal ramps uye ramps nizhnezubnyh Bugorkova mesial zvakaoma zvinyama pasi rezasi uye okumusoro incisors vestibular palatal pemvura.

Chii munyonga pamusoro Spee uye Wilson? On ichi akazotevera.

Sei kutsenga zvokudya?

Kana achiita lateral fambisa rezasi shaya, rwokunze mawere buccal cusps repasi meno yemasiraidhi pamusoro nokushanda parutivi yomukati mujinga rokumusoro buccal mazino, uye dzimwe ramps nizhnezubnyh lingual cusps Vaiisa pamusoro ramps wokunze yokumusoro palatal cusps. Anouya pokugadzwa chete zita kutaura buccal cusps pakati premolars uye molars.

Canines kudzivirira kuti zvakaoma zvinyama uye periodontal posterior mazino kubva zvakanyanya panguva kutsenga, uye naizvozvo, kana mukugadzira mazambuko vanobhadhara Cherechedzai Kudzikamiswa ari prosthesis kudzivisa periodontal kukuvara.

Kana contactsGoogle canines zvakafanana, ichibata mune lateral occlusions yunifomu mutoro inopiwa pamusoro TMJ, mazino, kutsenga tsandanyama uye periodontium panguva kutsenga. Zvose izvi uye inopa munyonga pamusoro Spee.

At palatal (occlusal) hukawanika vaikudzwa incisors uye canines pamwe mesial uye distal divi mupendero 2 ane chinotenderera unobva mazino tubercle panzvimbo dzapasi rechitatu zino.

Pakati ichi uye epakati cusp pakati nokuveza pamucheto iri palatal evaMedhia chinotenderera rine grooves kumativi ose. Dental tubercle akadana chikuru chikamu nezino, nzvimbo umo occlusal vokukurukura kutora nzvimbo. Izvi curvature guru muripo munyonga pakati Spee.

Palatine hillocks okumusoro posterior meno buccal kudanwa panotaurwa sezvo ivo zvokudya kupwanya uye kuziva hunhu kufamba mukati romunda occluding ari mandible, kusanganisira redistribution kubudisa masticatory masimba kuitira kuti kumboenda mutoro kutora mazino dög akabatana.

Sei occlusion makakombama?

Buccal hillocks okumusoro posterior mazino lingual inonzi inodzivirira pasina rubatsiro. Ndivo zvishoma neVadzidzi mhandu nechepakati occlusion kana, maererano vamwe vanyori, kwakadaro kuonana asina. Izvi zvokuchunisa basa rinoitwa zvokudya kupesana uye zvakasikwa mhandu dzavo mujinga ari zvishoma nezvishoma mumatope pamusoro, izvo inodzivirirawo pamatama uye rurimi panguva kutsenga kubva kuwana pakati pameno. Kudzamisa Spee munyonga zvakakodzera kuti chakaipa dög zvokudya.

Kwete mhesano (pfungwa) yunifomu, akawanda vokukurukura anoshorana meno zvikuru zvakanaka chimiro occlusions kutsenga basa riri vakasikwa Modelling pamusoro occlusion pemvura. Muchiitiko chino, zvinogoneka kuita kubudiswa zvokudya chero kusachinja-chinja. Kutsenga Kuparadzirwa nevezera kunoitika mhiri chikwesheso akabatana, pamwe risingamboshandisi mutoro pamusoro periodontium, uye panguva diki nguva contactsGoogle zvinoderedza erasure masticatory ndege. Contact anosika Kunetsana uye hillocks kutsiga ezasi rushaya pamwe nechepakati occlusion musimboti nomutswi mumaturi, kusanganisira chibingamupini kutamira rezasi rushaya ari occlusal munda. Izvi inopa munyonga pamusoro Spee (mu mufananidzo pazasi, unogona kuona mufananidzo wayo schematic).

Kana mazino zvisipo?

Pasina mazino, i.e. kurasikirwa occlusal pamusoro, nokuti ayo kupora ndivo occlusal Ndege achipfuura matatu pfungwa vari: vertices wechipiri dzakaderera molars (zvavo distal-buccal cusps) uye incisal pfungwa. Ndege ichi chinoshandiswa kumisa muenzaniso mandible ari articulator, semuenzaniso, vachishandisa balancer.

Occlusal pose mazino ari chinjikira ndege isina zvirimowo, anoumba rimwe munyonga sagittal mirayiridzo: mumwe concave uye convex kuti pasi nokuda rokumusoro shaya. mumwe munyonga kwakadaro inonzi munyonga kuti Spee kana occlusal sagittal munyonga. Iye chikamu denderedzwa ane centre iri anenge ari pakati muchadenga.

The zvakawanda chinozikamwa Spee munyonga?

Uyewo, maererano Spee, vatsvakurudzi uye vanoita, occlusal munyonga kwakabatana chose kuti articular nzira, nokuti iye, pamwechete munyonga mazino inoumbwa nharaunda, uye maererano, mazino uye articular musoro papfungwa pamusoro rimwe denderedzwa mberi uye steeper yakatenuka munzira muhudyu, zvikuru yunifomu occlusal concave munyonga. zvekungofungira kwakadaro nemasayendisiti vakasangana zvakawanda zvaaitaura. Zvimwe masayendisiti vanoti occlusal munyonga haagoni kunzi chidimbu chimwe denderedzwa. In kuenderera sagittal munyonga pakati Spee kazhinji anoenda kumusoro kana pazasi pejoinhi nzira, uye payo haisi muziso zvigadziko.

Sei pane kudiwa iri sagittal munyonga kuti occlusion?

Kana mandibular mberi kwebasa Vered uye achiburuka pitikoti pamwe musoro pamusoro yakatenuka articular tubercle. Saizvozvowo, rezasi shaya iri chichiburutswa pasi (kumashure chikamu) nokuumba dehiscence ari posterior nharaunda pakati pemitsara kwemeno. Contact anorovera lateral mazino zvinogoneka chete kana sagittal mutsetse anoda kutsenga pechiso kwemeno. Zvichitevera dzidziso iyi, inonzi occlusal zvakananga muripo munyonga.

The nharaunda tsunga 5,8-21,2 masendimita, paavhareji ukoshi -. 6.5-8.5 masendimita gobvu pfungwa occlusal munyonga - mesial tubercle repasi wokutanga matadza.

Nyaya anorondedzerwa zvakadzama munyonga pamusoro Spee.
