Abstract

Impakcija gornjeg očnjaka potpada među najčešće impakcije, odmah iza impakcije donjeg umnjaka. Očnjaci su impaktirani palatinalno u 85% slučajeva, a labijalno, odnosno bukalno u 15% slučajeva. Vestibularno smješteni očnjak uglavnom je
posljedica nedostatka prostora u luku, ali on najčešće nikne, dok je palatinalno položen očnjak anomalija položaja zuba koja nastaje bez obzira na prostor u zubnom luku. Etiološki faktori su raznoliki- dug i vijugav put izbijanja očnjaka, nepravilni ili nepostojeći lateralni incizivi, nasljeđe. Ektopični gornji očnjak često zahtjeva kompleksan multidisciplinarni pristup uključujući oralnu kirurgiju, restorativnu, parodontnu kao i ortodontsku terapiju. Faktori koji utječu na prognozu uključuju pacijentovu kooperativnost, dob,
sveukupno oralno zdravlje, skeletalne varijacije te prisutnost zbijenosti ili rastresitosti zubnog luka. Ovisno o slučaju specijelist se odlučuje za terapijski postupak- ekstrakciju mliječnog očnjaka, ortodontsko izvlačenje, kirurško odstranjivanje trajnog očnjaka, repoziciju, transplantaciju. Upoznavanje pacijenta i roditelja s mogućnostima liječenja i njihov informirani pristanak osnova je da se izbjegnu medicinsko pravni problemi.

Abstract (english)

The maxillary canine impaction is one of the most frequent dental impactions. Larger incidence of impaction is noted only in mandibular third molar. Canine is palataly impacted in 85% and buccaly in 15% of cases. Buccal impaction is caused by
inadequate arch space and usually only temporal. Palatal displacement of the maxillary canine is a positional anomaly that generally occurs despite adequate arch space. The etiology is multifactorial- long eruptive pathway, atypical morphology or
missing lateral incisors and heredity. The ectopic maxillary canine requires complex multidisciplinary treatment with surgery, restorative dentistry, periodontics and orthodontics. Treatment prognosis includes estimation of patient co-operation, age,
general oral health, skeletal variation, and presence of crowding or spacing in the arch. Depending on the case, different treatment can be administrated - extraction of the deciduous canine, orthodontic alignment, surgical removal of the permanent
canine, repositioning and transplantation. Detailed patient and parent informing about treatment options with informed consent is essential in pretreatment legislative.
