Abstract


Gigi dikatakan impaksi ektopik apabila mengalami malposisi yang disebabkan oleh faktor kongenital atau mengalami perubahan posisi yang disertai dengan kondisi patologis. Kondisi patologis yang sering menyertai gigi impaksi ektopik adalah kista dentigerous. Tujuan dari studi pustaka ini adalah untuk memaparkan odontektomi pada kasus molar ketiga ektopik yang disertai dengan kista dentigerous. Operasi ini adalah untuk menghilangkan faktor penyebab terjadinya kista dentigerous serta membersihkan lesi kista agar tidak berkembang semakin membesar. Pasien laki-laki 38 tahun mengeluhkan adanya sedikit benjolan pada pipi sebelah kanan namun tanpa disertai rasa sakit. Benjolan dirasakan mulai muncul dalam satu tahun terakhir. Hasil pemeriksaan radiografik menunjukkan gigi molar ketiga mandibula kanan berada pada sudut angulus mandibula disertai adanya gambaran radiolusen pada mahkotanya didiagnosa sebagai impaksi ektopik gigi molar ketiga mandibula kanan disertai kista dentigerous. Tindakan operasi odontektomi dan enukleasi kista dentigerous dilakukan secara ekstraoral dengan anastesiumum, pemilihan metode pengambilan ekstraoral karena posisi gigi yang telah berubah jauh dari posisi normal gigi molar ketiga mandibula. Telah dilakukan pengambilan gigi molar ketiga mandibula yang impaksi ektopik dan enukleasi kista dentigerous secara ekstraoral, karena posisi gigi impaksi yang ektopik di ramus mandibula. Pengambilan gigi impaksi secara ekstraoral sangat jarang sekali dilakukan, namun jika posisi gigi berada jauh sekali dari posisi normal maka pendekatan ekstraoral merupakan metode operasi yang akan mempermudah proses pengambilan gigi dan enukleasi kista serta dapat meminimalkan hilangnya tulang mandibula yang sehat.

 

ABSTRACT: Odontectomy of Ectopic Third Molar Associated with Dentigerous Cyst in Submandibular Region. Ectopic impacted tooth has been defined as malpositioned tooth caused by congenital factor or malpositioned tooth associated with pathologic condition. Pathologic condition associated with ectopic impacted tooth is dentigerous cyst. The purpose of this operation is to eliminate the causes of the dentigerous cyst and to raise cyst lesions that do not develop as they grow. A 38-year-old male patient complained of a painless slight swelling on his right cheek which occurred in the last one year. The radiograph examination shows an ectopic right mandibular third molar at the posterior border of the right angle of mandible, with an associated coronal radiolucency diagnosed as ectopic impacted right mandibular third molar associated with dentigerous cyst. The tooth and the cyst were removed surgically under general anesthetic via an extra-oral approach due to an extreme malposition of the tooth. The ectopic impacted right mandibular third molar and associated dentigerous cyst had been removed and enucleated surgically via extra-oral approach because the location of the ectopic impacted tooth was in the ramus of mandible. Extra-oral removal of ectopic mandibular third molar is very rare, however this approach will facilitate an easy removal and enucleation of an extremely malpositioned mandibular third molar associated with dentigerous cyst and minimize a loss of healthy mandibular bone.
