ipuleti ye-orthognathic engu-0.6 ye-anatomical L

Imigqa egxilile, ngokunyuka okungu-1 mm, ezifakelweni zihlinzeka ngosizo olubonakalayo lokugoba amapuleti.

Ukukhubazeka komlomo kanye ne-maxillofacial kubhekisela kubukhulu obungavamile kanye nokuma kwe-maxilla okubangelwa ukukhula okungavamile kwe-maxilla, ubuhlobo obungavamile phakathi kwe-maxilla engenhla nephansi kanye nobudlelwane bayo namanye amathambo e-craniofacial, kanye nobudlelwane obungavamile phakathi kwe-maxilla ne-maxilla. amazinyo, ukusebenza okungavamile kwesistimu yomlomo ne-maxillary kanye ne-morphology yobuso engavamile.Inhloso yokuhlinzwa kwe-orthognathic ukulungisa amazinyo alahlekile, ukulungisa i-arch yamazinyo ehlukene kanye nobudlelwane phakathi kwamazinyo nemihlathi, ukuqeda ukuphazamiseka phakathi kwamazinyo nemihlathi, hlela ukukhishwa kwamazinyo, futhi uqede ukuthambekela okuyisinxephezelo kwamazinyo, ukuze ukuhlinzwa kukwazi ukuhambisa ingxenye yethambo elisikiwe liyiswe endaweni eklanyelwe ukulungisa kahle, futhi kwakhiwe ubuhlobo obuhle phakathi kwamazinyo nemihlathi.

Emuva ngo-1928, uFauchard wazama ukulungisa ukugudluka kwezinyo elilodwa ngokucindezela amazinyo, kodwa ukuhlinzwa kokuhlinzwa kokukhubazeka kwamathambo nomhlathi kwasungulwa uHullihen ngo-1848 futhi kwabikwa okokuqala ngo-1849.Kusukela ngaleso sikhathi, nakuba izazi eziningi ziye zenza imizamo. ukuhlola nokwenza ngcono, umphumela wokwelapha awulungile ngenxa yobuchwepheshe obulinganiselwe kanye nezinga lezokwelapha ngaleso sikhathi, ukuze eminyakeni eyi-100 elandelayo, ukwelashwa kokukhubazeka kwamazinyo kanye ne-maxillofacial kuqhubekela phambili kancane.Kuze kube sekupheleni kwawo-1950, ngokuthuthukiswa kwe i-anesthesiology, ukuhlinzwa okuyisisekelo, i-anatomy esetshenziswayo kanye nezinsimbi ezikhethekile zokuhlinza, ukulungiswa kokuhlinzwa kokukhubazeka kwamazinyo kanye ne-maxillofacial kuye kwathuthuka ngokushesha.

Ngo-1957, u-Trauner no-Obwegeser babika okokuqala ukuthi i-sagittal split ramus osteotomy isebenzisa indlela ye-intraoral yathuthukiswa ngu-Dal Pony (1961), okumaka isigaba esisha sokwelashwa kokukhubazeka kwe-maxillofacial.Kusukela ngeminyaka yo-1970, ngenxa yeBell. kanye nemizamo yezazi eziningi, emhlathini kanye nezicubu zokuphakelwa kwegazi ohlelweni lwe-anatomy esetshenziswayo, futhi ukusika ukunikezwa kwegazi kwethambo ngemuva kwezinguquko eziguquguqukayo zokuphumelela, kuphinde kwabeka isisekelo sezinto eziphilayo zesimanje ukuhlinzwa komhlathi, ukuze kuzuzwe izinyo ngalinye. - - ukufakelwa kwethambo le-periosteal okunamathelayo kwe-composite tissue pedicle translocation, kunikeza isisekelo sesayensi nesiqiniseko sempumelelo.Ngaphezu kwalokho, ukusungulwa kwesimiso sokwelashwa okuhlangene kokuhlinzwa-orthodontic kwenza ukwelashwa kokuhlinzwa kokukhubazeka kwamazinyo kanye ne-maxillofacial kuphelele kakhulu, futhi kungena ngempela. isikhathi esisha sokuhlanganisa umsebenzi ne-morphology.

Ngenxa yokuthi ukwelashwa kokuhlinzwa kweziguli ezinokukhubazeka kwamazinyo kanye ne-maxillofacial kufanele kusekelwe ekukhubazekeni nasezimfuneko zokwelapha, inkimbinkimbi yamazinyo nethambo kufanele ivuleke futhi ihanjiswe ukuze kwakhiwe kabusha ubudlelwano bendawo obuyizinhlangothi ezintathu kanye nokusebenza kwesakhiwo esivamile samazinyo nesamathambo, kanye nokuthola umphumela ogculisayo wezimonyo we-maxillofacial.Ngakho-ke, uhlelo lokwelapha, izinyo?Ukulungiswa kobudlelwane, indawo yokusikwa kwethambo, isiqondiso kanye nebanga lokunyakaza kwethambo, kanye nokukhetha kwesu lokuhlinza kufanele konke kube kucatshangelwe ngokunembile futhi kuklanywe ngaphambi kokuhlinzwa, futhi umphumela wokwelapha olindelekile wecebo elikhethiwe kufanele ubikezelwe ngaphambi kokuhlinzwa.

Ukuhlinzwa kwe-Orthognathic kusetshenziselwa ukuxazulula ukungahambi kahle kokusebenza noma ukungahambi kahle kokwakheka kobuso okubangelwa ubukhulu obungavamile nokuma kwe-maxilla okubangelwa ukuthuthukiswa kwe-maxilla, kanye nobudlelwane obungavamile phakathi kobukhulu nokuma kwe-maxilla namanye amathambo obuso. Kungase kudingeke ukuhlinzwa ukuze kuthuthukiswe izici zobuso, okuhlanganisa i-alveolar eqinile engaphezulu kwe-alveolar anterior protrusion (i-buckteeth), i-alveolar anterior protrusion (overbite), ukuvuleka kwemihlathi emikhulu yangaphambili, kanye nokuchezuka okukhulu kwamathambo.
