Abstract

Razvoj dentalnih materijala za nadoknadu tvrdog zubnog tkiva s fizičko kemijskim svojstvima sličnim zubnom tkivu, doživio je iznimno veliki napredak u posljednjih dvadesetak godina. Cilj kojem oduvijek teži restaurativna stomatologija je osigurati čvrstu i trajnu vezu između tvrdog zubnog tkiva i restoracija. Taj cilj nije lako ostvariti s obzirom da je proces adhezivnog povezivanja različit u caklini i dentinu s obzirom na njihovu strukturnu različitost.
Caklinsko-dentinski adhezijski sustavi se vežu mikromehanički i kemijski za zub. Osnova mikromehaničke retencije jest potpuno prožimanje eksponirane kolagene mreže adhezijskom smolom te prodiranje i uklještenje smolastih zubaca unutar dentinskih tubulusa s posljedičnim stvaranjem jednolikog hibridnog sloja i hermetički zatvorenih tubulusa.
Posljedica tehnološkog razvoja jesu razvoj i stalne promjene adhezijskih sustava. Postoje različite podjele adhezijskih sustava koje su s vremenom usavršavane, a najčešće upotrebljavana u kliničkom radu je podjela caklinsko-dentinskih sustava prema interakciji sa zubnim tkivom.
Riječ je o standardnom jetkajuće-ispirućem adhezijskom sustavu te najnovijoj generaciji samojetkajućih adhezijskih sustava, koja ne zahtjeva prilikom primjene postupke jetkanja i ispiranja površine supstrata te samim time donosi i prednosti nad standardnim jetkajuće-ispirućim adhezijskim sustavima.
Objedinjenjem dviju početnih faza, jetkanja i ispiranja supstrata, tijekom rada smanjuju se pogreške koje nastaju pri aplikaciji i rukovanju kiselinom.
Pojavom samojetkajućih adhezijskih postupaka na tržištu klinički rad je olakšan, jednostavniji i vremenski skraćen te postaje imperativ u mnogim stomatološkim postupcima.

Abstract (english)

Dental materials for hard-tooth tissue replacement with tooth tissue compatible chemical and physical characteristics have come a long way in the last twenty years.
Providing a firm and lasting connection between hard tooth tissue and the restoration materials always been restorative dentistry’s goal. This is not always easy to accomplish, considering that the adhesive bonding process is different in the enamel and in the dentine, due to their structural diversity.
Enamel and dentine adhesive systems bind micro-mechanically and chemically to the tooth. The basis of micromechanical retention is complete embracement of the collagen network with adhesive resin and penetration and incarceration of the resinous spikes within the dentin tubules. Consequently, a hybrid layer is formed with hermetically sealed tubules.
Technological development has enabled constant upgrading of the adhesive systems. There are several adhesive system classifications that are constantly updated. The most commonly used system in clinical practice is the enamel-dentine classification based on the interaction with the tooth tissue.
The latest generation of the self-etching adhesive systems do not require the separate etching and rinsing procedures, and therefore have an advantage over the standard etching-rinsing systems.
By combining the two initial steps, etching and rinsing, mistakes that are prone to happen are minimized in the latest generation of self-etching adhesive systems.
The self-etching adhesive systems have simplified the clinical practice, reduced the procedure duration and have become an imperative in a number of dental procedures.
