Abstract

Impaktirani zubi su oni zubi koji se ne pojave unutar zubnog luka u očekivanom vremenu
predviđenom za njihovo nicanje. Ta pojava je najčešće asimptomatska, no ponekad može
uzrokovati probleme kao što su karijesne lezije, infekcije, ciste itd. Najčešće impaktirani zubi
su treći kutnjaci, zatim maksilarni očnjaci, mandibularni pretkutnjaci te maksilarni centralni
sjekutići. Uzroci njihove impakcije su brojni, a dijele se u tri osnovne skupine: genetski,
sistemski te lokalni faktori. Kako bi se s terapijom impakcije moglo započeti što ranije, jako
je važna rana i dobra dijagnostika. Kliničkim pregledom koji uključuje inspekciju i palpaciju
uočava se nedostatak zuba, a raznim se radiološkim metodama potvrđuje postojanje impakcije
te prikazuje položaj impaktiranog zuba u odnosu na okolne strukture. S obzirom na položaj
zuba u čeljusti planira se terapijski postupak koji je izuzetno složen i zahtijeva
interdisciplinarnu suradnju oralnog kirurga, ortodonta i parodontologa. Impaktirani zubi
najčešće se liječe neekstrakcijskim terapijskim postupkom koji uključuje ortodontsko
otvaranje prostora u zubnom luku, kirurško prikazivanje krune te izvlačenje zuba u
odgovarajući položaj. Za prikaz krune impaktiranog zuba mogu se koristiti tri kirurška
zahvata: ekscizijska metoda, metoda apikalno pomaknutog režnja te metoda zatvorene
erupcije. Izbor metode ovisi o vrsti impaktiranog zuba te njegovom smještaju. Za početak
terapije jako je važan dobar plan te individualni pristup jer se time komplikacije, kao što su
resorpcija korijena, gubitak kosti te loša estetika, svode na minimum

Abstract (english)

Impacted teeth are those teeth that do not appear inside the dental arch in the expected time
estimated for their eruption. This phenomenon is usually asymptomatic, but sometimes it can
cause problems such as carious lesions, infections, cysts, etc. The most commonly impacted
teeth are the third molars, followed by the maxillary canines, mandibular premolars, and
maxillary central incisors. The causes of their impaction are numerous, divided into three
basic groups: genetic, systemic and local factors. In order to start impaction therapy as early
as possible, early and good diagnosis is very important. Clinical examination, which includes
inspection and palpation, reveals a lack of tooth while various radiological methods confirm
the existence of impaction. Given the position of a tooth in the jaw, a therapeutic procedure is
planned which is extremely complex and requires interdisciplinary cooperation of the oral
surgeon, orthodontist and periodontist. Impacted tooth is most often treated with a nonextraction therapeutic procedure that includes orthodontic opening of the space in the dental
arch, surgical presentation of the crown and extraction of the tooth in the appropriate position.
Three surgical procedures can be used to expose the crown of an impacted tooth: the excision
method, the apically displaced lobe method, and the closed eruption method. The choice of a
method depends on the type of impacted tooth and its location. A good plan and an individual
approach are very important for the beginning of a therapy as it reduces complications such as
root resorption, bone loss and poor aesthetics.
