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, ubudlelwano obungavamile phakathi kwe-maxilla engenhla nephansi kanye nobudlelwane bayo namanye amathambo e-craniofacial, kanye nobudlelwane obungavamile phakathi kwe-maxilla namazinyo, umsebenzi ongavamile we-maxillary system kanye ne-maxillary system kanye ne-maxillary system kanye ne-amorphology ye-oral. Ukuhlinzwa kwe-orthognathic ukulungisa amazinyo angahambi kahle, ukulungisa i-arch yamazinyo ehlukene kanye nobudlelwano phakathi kwamazinyo nemihlathi, ukuqeda ukuphazamiseka phakathi kwamazinyo nemihlathi, ukuhlela ukukhishwa kwamazinyo, nokuqeda ukuthambekela okuyisinxephezelo kwamazinyo, ukuze ukuhlinzwa kukwazi ukuhambisa ingxenye yethambo elisikiwe liyise endaweni eklanyelwe ukulungisa kahle, futhi kwakhiwe ubuhlobo obuhle phakathi kwamazinyo nemihlathi.

Kusukela ngo-1928, uFauchard wazama ukulungisa ukugudluka kwezinyo elilodwa ngesibambo samazinyo, kodwa ukuhlinzwa kokuhlinzwa kwamathambo nokukhubazeka komhlathi kwasungulwa nguHullihen ngo-1848 futhi kwabikwa okokuqala ngo-1849. ukukhubazeka kwamazinyo kanye ne-maxillofacial kuqhubeka kancane.Kuze kube sekupheleni kwawo-1950, ngokuthuthukiswa kwe-anesthesiology, ukuhlinzwa okuyisisekelo, i-anatomy esetshenzisiwe 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 kokuhlinzwa kokukhubazeka okukhulu kwe-maxillofacial. futhi ukusika ithambo ukunikezwa kwegazi ngemva izinguquko ashukumisayo ukuphumelela, ngokuqhubekayo wabeka isisekelo biological of yesimanje ukuhlinzwa emhlathini, ukuze kufinyelelwe izinyo ngalinye - - okunamathelayo periosteal bone bone transplantation of composite izicubu pedicle translocation, inikeza isisekelo zesayensi kanye isiqinisekiso sempumelelo.Ngaphezu kwalokho, ukusungulwa isimiso sokuhlinzwa-orthodontic ukwelashwa okuhlangene kwenza ukuhlinzwa kanye ne-maxillo entsha ingene isikhathi sokuhlinzwa kanye ne-maxillo entsha yokwelashwa kwe-dental kanye ne-maxillo entsha. yokuhlanganisa umsebenzi ne-morphology.

Ngenxa yokuthi ukwelashwa kokuhlinzwa kweziguli ezinokukhubazeka kwamazinyo kanye ne-maxillofacial kufanele kusekelwe ekukhubazekeni kanye nezidingo zokwelashwa, inkimbinkimbi yamazinyo nethambo kufanele ivuleke futhi ihanjiswe ukuze kwakhiwe kabusha ubudlelwano bendawo obunezinhlangothi ezintathu kanye nokusebenza kwesakhiwo esivamile samazinyo kanye ne-maxillofacial, kanye nokuthola umphumela ogculisayo wezimonyo zokulungiswa kwethambo le-maxillofacial. ukusika, isiqondiso kanye nebanga lokunyakaza kwamathambo, nokukhetha uhlelo lokuhlinza kufanele konke kucatshangelwe ngokunembile futhi kuklanywe ngaphambi kokuhlinzwa, futhi umphumela olindelekile wokwelapha wepulani elikhethiwe kufanele ubikezelwe ngaphambi kokuhlinzwa.

Ukuhlinzwa kwe-Orthognathic kusetshenziselwa ukuxazulula ukungahambi kahle kokusebenza noma ukungahambi kahle kwe-facial morphology okubangelwa usayizi ongavamile nokuma kwe-maxilla okubangelwa ukuthuthukiswa kwe-maxilla, kanye nobuhlobo obungavamile phakathi kobukhulu nokuma kwe-maxilla namanye amathambo obuso.Ukuhlinzwa kungase kudingeke ukuze kuthuthukiswe izici zobuso, kuhlanganise ne-albubeolar anterior ephansi ye-alborveolar anterior (i-albubeolar anterior protrusion) ukuphuma (ukweqile), izimbobo ezinkulu zemihlathi yangaphambili, nokuchezuka okukhulu kwamathambo.
