ORTHODONTIC TREATMENT OF ANKYLOSED PERMANENT TEETH AFTER SURGICAL LUXATION.

Tooth ankylosis is the process of the fusing of a tooth root to the surrounding alveolarbone whereby the periodontal ligament is lost, and in later stages, a tooth root isreplaced by the bone, which eventually results in the tooth loss. The etiology of thiscondition includes trauma, genetic factors, metabolic anomalies, local anomalies, endocrine anomalies, iatrogenic causes as well as idiopathic factors. Theconsequences are evident and involve prevented ankylosed tooth growth causing non-occlusion, adjacent teeth inclination, opponent teeth eruption and cause malocclusion. Therapy can be surgical, conservative, orthodontic or combined. The case presentedin this paper illustrates the efficacy of the surgical luxation of ankylosed teethfollowed by the immediate application of orthodontic elastic force. The outcome maybe debatable, but considering a poor prognosis for ankylosed teeth, the suggested treatment represents a better therapeutic choice than facing potential consequences of administering or not administering the usual treatment of ankylosed permanent teeth.

Ankiloza zuba je proces srastanja korena zuba za okolno koštano tkivo u kome dolazi do gubitka periodontalnog ligamenta, a u kasnijim fazama do pretvaranja korena zuba u koštano tkivo i do gubitka samog zuba. Etiologija ovakvih stanja kreće se od traume, genetske predispozicije, poremećaja metabolizma, lokalnih poremećaja, endokrinih poremećaja, jatrogenih uzroka pa do idiopatskih faktora. Posledice su evidentne i odnose se na izostanak rasta ankilotičnih zuba usled čega dolazi do nonokluzije, inklinacije susednih zuba, erupcije zuba oponenata i narušavanja cele okluzije. Terapija može biti hirurška, konzervativna, ortodontska ili kombinovana. Slučaj prikazan u ovom radu svedoči o efikasnosti hirurške luksacije ankilotičnih zuba praćene neposrednom primenom ortodontske elastične vuče. Ishod može biti diskutabilan, ali s obzirom na lošu prognozu ankilotičnih zuba, hirurška luksacija predstavlja bolji terapeutski izbor od suočavanja sa mogućim posledicama izostanka ili primene uobičajenih tretmana ankilotičnih zuba.
