Abstract

Maksilarni očnjaci nalaze se na drugom mjestu po učestalosti impakcije. Od toga jedna trećina impaktiranih gornjih očnjaka smještena je labijalno, dok se ostale dvije trećine odnose na palatinalno impaktirane očnjake. Dijagnoza se postavlja pomoću vizualnog pregleda, palpacije i radiološke analize. Terapija impakcije očnjaka može biti preventivna (interceptivna) ili kirurška, a nakon toga i ortodontska. Rano postavljanje dijagnoze pospješuje rezultate interceptivne terapije. Međutim, u nekim situacijama interceptivna metoda neće biti djelotvorna i pacijenta će se morati naposljetku uputiti na kirurško prikazivanje. Ortodontsko-kirurško liječenje impaktiranih gornjih očnjaka uključuje kirurško prikazivanje zahvaćenog zuba nakon čega slijedi ortodontska metoda izvlačenja koja zub usmjerava i poravnava u zubni luk. Za zahvaćene zube primjenjuju se tri glavne kirurške metode: ekscizijska, metoda apikalnog režnja i metoda zatvorene erupcije. Prije bilo kojeg kirurškog postupka presudno je odrediti točan položaj impaktiranog zuba jer on određuje vrijeme i metodu kirurškog prikazivanja. U terapiji impaktiranih zubi zbog kompliciranosti i dugotrajnosti postupka moguće su brojne komplikacije koje će značajno umanjiti uspjeh završene terapije. Najčešće komplikacije su gubitak kosti ili zuba, resorpcija korijena, gingivalna recesija ili narušena estetika. Nastaju zbog pogrešno postavljene dijagnoze, nepravilno izvedenog kirurškog zahvata ili primjene neodgovarajuće ortodontske biomehanike. Samo s interdisciplinarnim pristupom od općih stomatologa do specijalista kirurgije, ortodoncije i parodontologije, impaktirani maksilarni očnjaci mogu se uspješno liječiti.

Abstract (english)

Maxillary canines are the second most common impacted teeth. Upper canines can be impacted labially and palatally in the ratio 1:3. The diagnosis is based on visual examination, palpation and radiographic analysis. The treatment of impacted canines can be interceptive or surgical, followed by orthodontic treatment. Early detection improves the results of interceptive treatment. However, in some situations this method is not effective and the patients have to undergo surgery. Orthodontic and surgical management of impacted maxillary canines includes surgical exposure followed by orthodontic extraction in order to align the teeth and to bring the impacted tooth into the dental arch. There are three main surgical techniques applied for impacted teeth: the open eruption technique, the apically repositioned flap and the closed eruption technique. Prior to any surgical procedure, it is crucial to determine the exact position of the impacted tooth as it determines the time and the method of surgical exposure. Due to its complexity and longevity, the treatment of impacted teeth often results in numerous harmful complications. Whether it is bone or tooth loss, root resorption, gingival recession or impaired aesthetics, it will significantly decrease the success of the therapy. Complications usually occur due to misdiagnosis, improperly performed surgical procedures or inadequate orthodontic biomechanics. The treatment of impacted teeth requires interdisciplinary cooperation between general dentists, dental surgeons, orthodontists and sometimes periodontists to successfully treat the impacted maxillary canines.
