Abstract

Nadogradnje zuba su fiksnoprotetski nadomjestci na avitalnom zubu i uvijek služe kao potpora različitim vrstama krunica. Uvjet za izradu nadogradnje je pravilno endodontski izliječen zub. Indicirane su u svim kliničkim situacijama, gdje nadostaje dovoljno kliničke krune zuba, da bi se mogla retinirati krunica. Najčešće je potreba za izradom nadogradnje lom kliničke krune avitalnog zuba, ali i kod abrazije zuba se upotrebljavaju, gdje je snižena klinička kruna , uz uvjet da se zub predhodno endodontski liječi. Nakon punjenja kanala nadogradnjaom se produži klinička kruna zuba. U kliničkoj uporabi dolazi čitav niz nadogradnji koje se razlikuju po postupku izrade, materijalu i oblicima, ekstrakoronarnog i intraradikularnog dijela nadogradnje. Temeljna podjela nadogradnji je na individualne i konfekcijske. Individualne nadogradnje su puno preciznije jer nadogradnju prilagođavamo zubu. Postupak izrade nadogradnje uključuje suradnju zubotehničkog laboratorija i samim time produžuje terapijski postupak. Konfekcijske nadogradnje dolaze kao gotovi proizvodi u različitim oblicima i kod njih zub prilagođavamo nadogradnji. Postupak izrade je kraći, ali ostaje otvoreno pitanje dobrog postavljanja indikacije za ovu vrstu nadomjestka zbog veličine i oblika ekstrakoronarnog dijela. Preparacija zuba posebice intraradikularnog dijela nadogradnje je vrlo važan i precizan zahvat, pa zatijeva spretnost i vještinu doktora dentalne medicine. Postupak cementiranja također je izuzetno važan, kao i izbor vrste cementa ovisno o vrsti i materijalu nadogradnje.

Abstract (english)

Dental post and cores are tooth upgrades as a part of fixed-prosthetic treatment on the non vital tooth. They always serves as support for different types of crowns. The condition for upgrading the tooth structure and made post and core is a properly endodontically cured tooth. They are also indicated in all clinical situations, where there is a lack of clinical tooth crowns for the retintion the crown. Most commonly clinical situations for indication for posta and cores are non vital tooth crown fractures . They can be also needed in the abrasion of the teeth, where the reduction of the crown length is present, providing extension of the clinical crown length after endodontic procedure.
Nowadays there are a lot of clinical procedures with the whole range of upgrades that differ in the manufacturing process, material and form, extracoronary and intraradular part of the upgrade. The basic clasiffication of the tooth upgrades is on individual post and cores and ready-made post and cores.
Individual post and cores are much more precise because the upgrade is adjust to the tooth. The process of upgrading involves the co-operation of the dnetal laboratory thus extending the clinical procedure. Ready made upgrades comes as finished products in various shapes and materials and the tooth is needed to be adapted to them . The clinical procedure is shorter, but the open question remains, are we difined good indication of this type of substitution due to the size and shape of the extracoronal part of the ready made post and cores. The preparation of the tooth, especially of the intraradicular part of the upgrading is a very important and accurate procedure, and needs a skill of the doctor of dental medicine. The cementing process is also extremely important as well as the choice of cement types depending on the type and material of the post and core upgrade of the tooh.
