Abstract

Estetika lica predmet je proučavanja još od davnina. Ortodoncija kao
specijalistička grana, razvija se krajem 19. stoljeća kad Angle definira tri tipa
malokluzije. Danas je nezadovoljavajuća estetika lica glavna indikacija za
ortodontsku terapije. Cilj terapije nije samo postići idealnu okluziju već dobiti i
skladan i harmoničan izgled mekih tkiva lica. Kod planiranja terapije potrebno je
analizirati meka tkiva lica odvojeno od dentoskeletne analize. Radimo frontalnu
analizu lica te analizu profila. Analiza lica u frontalnoj ravnini sastoji se od
vertikalne i horizontalne komponente, dok u analizi profila lica koristimo linearna i
angularna mjerenja kao što su S-linija, H-linija, E-linija, B-linija, nazolabijalni i
mentolabijalni kut. Općenito, pojam malokluzija označava nepravilan odnos između
zubi ili dvaju zubnih lukova. Uzroci malokluzija su specifični, nasljedni te posljedica
utjecaja okoliša. Njihovom interakcijom dolazi do različitih ortodontskih anomalija
koje imaju karakterističan izgled lica. Anomalije klase III su prava progenija i
pseudoprogenija. Pacijenti s pravom progenijom imaju konkavan profil, izduženu
donju trećinu lica, prominentnu bradu i zadebljalu donju usnu koja je ispred gornje.
Kod pacijenata s pseudoprogenijom, profil je konkavan, maksila je nedovoljno
razvijena dok je mandibula normalna. Anomalije klase II dijelimo na klasu II/1 i
klasu II/2. Pacijenti s klasom II/1 imaju konveksan profil lica, prominentnu gornju
usnu, uvučenu bradu, dok kod pacijenata s klasom II/2 nalazimo konveksan profil
lica, skraćenu donju,a povećanu srednju trećinu lica te prominentan nos i bradu.
Otvoreni zagriz je anomalija u vertikalnoj ravnini koju karakterizira izdužena donja
trećina lica i inkopetencija usana.

Abstract (english)

People have been studying facial aesthetics since ages. Orthodontics as a
specialist branch was defined in the end of the 19th century when Angle defined
three types of malocclusion. Nowadays orthodontic therapy is needed when dealing
with unsatisfactory facial aesthetics. The aim of therapy is not only to achieve ideal
occlusion but also to make soft facial tissue look harmonious. It is of great
importance to analyze soft facial tissue separate from dentoskeletal analysis when
planning therapy. Frontal facial analysis and profile analysis are both done. Frontal
plane facial analysis consists of a vertical component and a horizontal component.
When analyzing face profile linear and angular measurements such as S- line, H-
line, E- line, B-line, and nasolabial and mentolabial angles are used. The term
malocclusion refers to a situation when teeth or two dental arches are not positioned
properly. The causes of malocclusion are of specific nature; they are hereditary and
occur due to the influence of the environment. Various orthodontic anomalies occur
when these factors interact. These anomalies have a specific look. Third class
anomalies are real progenia and pseudoprogenia. Patients with real progenia have a
concave profile and the lower third of the face is elongated. The chin is prominent
and the lower lip is thickened and in front of the upper one. Patients with
pseudoprogenia have a concave profile. Their maxilla is not well developed and the
mandible is normal. Second class anomalies are divided into types II/1 and II/2.
Patients with type II/1 anomaly have a convex facial profile, a prominent upper lip
and a recessed chin whereas patients with type II/2 have a convex facial profile,
contracted lower and enlarged middle part of the face as well as a prominent nose
and a beard. An open bite is a vertical plane anomaly characterized by an elongated
lower third of the face and lip incompetence.
