Abstract

Bezubost se danas uspješno rješava sa pokrovnom protezom retiniranom ili poduprtom
implantatima. Ona predstavlja zamjenu za konvencionalnu potpunu protezu. Pokrovna proteza
na implantatima značajno poboljšava kvalitetu života.
Tijekom razvoja dentalne implantologije, razvijale su se različite makro i mikro karakteristike
dentalnih implantata, a samo određene su prisutne još i danas. One utječu na preživljavanje
implantata. Makro karakteristike podrazumijevaju makro dizajn, dakle oblik i geometriju
implantata, a mikro karakteristike podrazumijevaju površina implantata i tehnike njene obrade.
One su važan faktor u osiguravanju uspješne osteointegracije. Omogućavaju adheziju stanica na
površinu implantata, veći kontakt kost - implantat i ubrzavaju osteointegraciju, koja je ključ
dugoročnog uspjeha implantata. Danas se koriste uglavnom cilindrični implantati s navojima, a
površine implantata se modificiraju na različite načine kako bi se postigla odgovarajuća
hrapavost. Tehnike modifikacije površine implantata mogu biti aditivne i ablativne. Ablativne
tehnike danas prevladavaju.
Određene karakteristike implantata važno je imati na umu kako bi se terapija pokrovnom
protezom na implantatima prilagodila pacijentu i kako bi se konačni ishod terapije učinio
predvidljivijim.
Stopa preživljavanja implantata pod pokrovnom protezom je visoka, ali treba uzeti u obzir da na
nju mogu utjecati brojni drugi faktori vezani uz sam implantat kao i oni vezani uz pacijenta, a
ne samo makro i mikro karakterstike implantata.

Abstract (english)

Today, edentulism is successfully solved with an implant supported or retained overdenture. It is a
replacement for the conventional complete denture. An implant overdenture
significantly improves the quality of life.
During the development of dental implantology, various macro and micro characteristics of dental
implants were developed, but only some are still in use today. They affect the survival of implants.
Macro characteristics imply macro design, i.e. the shape and the geometry of the implant, while
micro characteristics imply the surface of an implant and the techniques of its modification. Both
are important factors in ensuring successful osseointegration. They enable cell adhesion to the
implant surface, larger bone-implant contact, and an acceleration of osseointegration, which is the
key to the long-term success implants. Cylindrical threaded implants are the ones mostly used
today, and their surface is modified in various ways to achieve the appropriate roughness. Implant
surface modification techniques in current use are additive and ablative, with the ablative technique
being the most prevalent today.
In order to adapt the implantoprosthetic overdenture therapy to an individual patient, and to make
the final outcome of the therapy more predictable, it is important to keep those implant
characteristics in mind.
The survival rate of implants under an overdenture is high but it should be taken into consideration
that it can be influenced by a number of other factors related to the implant itself, as well as by
those related to the patient, and not solely by the macro and micro characteristics of the implant.
