ipleyiti ye-orthognathic ye-0.6 ye-anatomical L

Imigca edibeneyo, kwi-1 mm increments, kwii-implants zibonelela ngoncedo olubonakalayo lokugoba ipleyiti.

Ukukhubazeka komlomo kunye ne-maxillofacial kubhekiselele kubukhulu obungaqhelekanga kunye nokumila kwe-maxilla okubangelwa ukukhula okungaqhelekanga kwe-maxilla, ubudlelwane obungaqhelekanga phakathi kwe-maxilla ephezulu kunye nezantsi kunye nobudlelwane bayo namanye amathambo e-craniofacial, kunye nobudlelwane obungaqhelekanga phakathi kwe-maxilla kunye ne-maxilla ye-maxilla. amazinyo, umsebenzi ongaqhelekanga wenkqubo yomlomo kunye ne-maxillary kunye ne-morphology yobuso engaqhelekanga.Injongo yotyando lwe-orthognathic kukulungisa amazinyo alahlekileyo, ukulungelelanisa i-arch yamazinyo edibeneyo kunye nobudlelwane phakathi kwamazinyo kunye nemihlathi, ukuphelisa ukuphazamiseka phakathi kwamazinyo kunye nemihlathi, lungisa ukukhutshwa kwamazinyo, kwaye uphelise ukuthambekela kwembuyekezo kwamazinyo, ukwenzela ukuba utyando lukwazi ukushenxisa icandelo lethambo elisikiweyo kwindawo eyilelweyo yokulungisa kakuhle, kwaye kuseke ubudlelwane obuhle phakathi kwamazinyo nemihlathi.

Kwangowe-1928, uFauchard waye wazama ukulungisa izinyo elinye ngokugxothwa kwamazinyo, kodwa unyango lotyando lwezinyo elingamathambo nolwemihlathi lwaveliswa nguHullihen ngowe-1848 lwaza lwanikelwa ingxelo okokuqala ngowe-1849. Ukususela ngoko, nangona abaphengululi abaninzi baye benza imigudu ukuhlola nokuphucula, umphumo wonyango awufanelekanga ngenxa yeteknoloji elinganiselwe kunye nenqanaba lezonyango ngelo xesha, ukuze kwiminyaka eyi-100 elandelayo, unyango lwe-deformity yamazinyo kunye ne-maxillofacial luqhubela phambili ngokucothayo.Kuze kube sekupheleni kweminyaka yoo-1950, kunye nophuhliso lwe i-anesthesiology, utyando olusisiseko, i-anatomy esetyenzisiweyo kunye nezixhobo ezikhethekileyo zotyando, ukulungiswa kotyando lwamazinyo kunye ne-maxillofacial deformities iphuhliswe ngokukhawuleza.

Kwi-1957, i-Trauner kunye no-Obwegeser babika okokuqala ukuba i-sagittal split ramus osteotomy isebenzisa indlela ye-intraoral yaphuculwa nguDal Pony (1961), ephawula inqanaba elitsha lonyango lonyango lwe-maxillofacial deformities.Ukusukela kwi-1970, ngenxa yeBell. kunye nemizamo yabaphengululi abaninzi, emhlathini kunye nenkqubo yokunikezelwa kwegazi kwezicubu ze-anatomy esetyenzisiweyo, kunye nokusika ithambo legazi emva kotshintsho oluguquguqukayo lwempumelelo, ngakumbi wabeka isiseko sebhayoloji yanamhlanje utyando lwemihlathi, ukuze kuphunyezwe izinyo ngalinye. - - ithambo elincangathi le-periosteal transplantation ye-composite tissue pedicle translocation, ibonelela ngesiseko senzululwazi kunye nesiqinisekiso sokuphumelela.Ukongezelela, ukusekwa komgaqo wotyando-othodontic odibeneyo wonyango wenza unyango lotyando lwamazinyo kunye ne-maxillofacial deformities lugqibelele ngakumbi, kwaye lungena ngokwenene. ixesha elitsha lokudibanisa umsebenzi kunye ne-morphology.

Ngenxa yokuba unyango lotyando lwezigulana ezinokukhubazeka kwamazinyo kunye ne-maxillofacial kufuneka lusekwe kukhubazeko kunye neemfuno zonyango, i-complex yamazinyo kunye nethambo kufuneka isikwe ivuleke kwaye ihanjiswe ukuze iphinde yakhe ubudlelwane besithuba se-three-dimensional kunye nomsebenzi wesiqhelo samazinyo kunye ne-maxillofacial structure, kunye nokufumana isiphumo esanelisayo se-cosmetic ye-maxillofacial.Ngoko ke, isicwangciso sonyango, izinyo?Ukulungelelaniswa kobudlelwane, indawo yokutyunjwa kwethambo, isalathiso kunye nomgama wokuhamba kwethambo, kunye nokukhethwa kwesicwangciso sotyando kufuneka kube konke. kuqwalaselwa ngokuchanekileyo kwaye kuyilwe phambi kokusebenza, kunye nesiphumo esilindelekileyo sonyango sesicwangciso esikhethiweyo kufuneka siqikelelwe kwangaphambili.

Utyando lwe-Orthognathic lusetyenziselwa ukusombulula ukungahambi kakuhle komsebenzi okanye ukungahambi kakuhle kwe-facial morphology okubangelwa ubungakanani obungaqhelekanga kunye nokumila kwe-maxilla ebangelwa kuphuhliso lwe-maxilla, kunye nobudlelwane obungaqhelekanga phakathi kobukhulu kunye nokumila kwe-maxilla kunye namanye amathambo obuso. Utyando lunokufuneka ukuze kuphuculwe iimpawu zobuso, kubandakanywa ne-alveolar anterior protrusion (i-buckteeth), i-alveolar ephantsi ye-alveolar anterior protrusion (overbite), ukuvuleka kwemihlathi enkulu yangaphambili, kunye nokuphambuka okukhulu kwamathambo.
