Abstract

Iako se preventiva u dentalnoj medicini i životni standard poboljšavaju s godinama, i dalje postoji
velika potreba za protetskom rehabilitacijom. U cilju olakšanja i ubrzanja procesa izrade koja
uključuje brojne korake, razvile su se digitalne metode izrade protetskih radova. Protetski se radovi
već godinama uspješno izrađuju glodanjem blokova materijala, dok 3D ispis posljednjih godina
postaje sve zastupljenija metoda izbora, osobito pri izradi metalnih i polimernih radova. 3D ispisom
nastoji se postići ušteda materijala jer tehnikom slojevanja točnih obrisa protetskog rada ne dolazi
do suvišne potrošnje materijala za razliku od metode glodanja koja ima veliki utrošak
neiskorištenog materijala preostalog frezanjem blokova. Ušteda materijala, klinički
zadovoljavajuća preciznost i povećana produktivnost svrstavaju 3D ispis među konkurentne
metode pri odabiru načina izrade. Aditivne tehnike izrade u širem smislu dijele se na one kojima
se obrađuju polimerni materijali, kao što su stereolitografija, digitalna svjetlosna obrada i fuzijsko
depozicijsko modeliranje te tehnike laserskog taljenja kojima se obrađuju metalni materijali.
Metalne osnove mobilnih protetskih radova vrlo se jednostavno i uspješno izrađuju metodom
laserskog taljenja, čime je komplicirana izrada složene metalne osnove djelomičnih proteza
svedena na što jednostavniji proces. Iako razvijen i primjenjiv u kliničkom radu, 3D ispis pokazuje
određene nedostatke koji zahtijevaju završnu konvencionalnu obradu protetskih radova, ali se
očekuje da će brzi razvoj metoda i materijala u sljedećim godinama naći rješenje za te prepreke.

Abstract (english)

Although prevention in dentistry and standard of living improve over time, there is still a great need
for prosthetic rehabilitation. In order to facilitate and speed up the process of fabrication, which
includes many different steps, digital methods of prosthetic restorations fabrication have been
developed. Prosthetic restorations have been successfully fabricated by milling blocks of materials
for years, while 3D printing has become an increasingly common method of choice in recent years,
especially in the fabrication of metal and polymer restorations. 3D printing aims to achieve material
savings, since the technique of layering the exact contours of prosthetic restorations does not
require excessive material consumption, unlike the milling method, which leaves considerable
amounts of unused material after milling of blocks. Material savings, clinically satisfactory
precision and increased productivity place 3D printing among competitive methods when choosing
a method of fabrication. Additive fabrication techniques in a broader sense are divided into the
ones used for processing polymers, e.g. stereolithography, digital light processing and fused
deposition modeling, as well as laser melting techniques, which are used with metals. Metal
frameworks of removable prosthetic restorations are fabricated by laser melting in a very simple
and successful way, which reduces the complicated process of metal framework fabrication to a
more simple process.
