Abstract

Implantoprotetika je grana dentalne medicine koja se u zadnjih 20-ak godina jako razvila, a takav trend se i nastavlja. Sama uspješna oseointegracija implantata više nije jedini kriterij po kojem se smatra da će protetička terapija imati dugoročan uspjeh. Za dugotrajan uspjeh, osim oseointegriranog implantata, mora se postići i adekvatan odgovor mekih periimplantatnih tkiva. Integracija mekih tkiva oko implantata jedna je od ključnih točaka za uspjeh jer meka tkiva štite kost i implantat od prodora bakterija, sprječavaju recesiju gingive te resorpciju kosti uzrokovanu bakterijama. Materijal i oblik implantatne nadogradnje imaju važnu ulogu u biološkom odgovoru mekih tkiva. Rad je baziran na pregledu dostupne znanstvene i stručne literature na engleskom jeziku, izabrane pretaživanjem na PubMedu po ključnim riječima titanij, cirkonij-oksid, implantatna nadogradnja. Uključeni su radovi objavljeni unutar 10 godina, studije s najmanje 10 pacijenata i studije u trajanju od najmanje 1 godine. Prilikom evaluacije uzeti su u obzir sljedeći kriteriji: dubina sondiranja (PPD), krvarenje pri sondiranju (BOP), akumulacija plaka,
recesije (REC), razina kosti (MBL) te biološke komplikacije. Pregledom relevantne literature razvidno je da su titanijske implantatne nadogradnje još uvijek zlatni standard. Titanij ima dobra mehanička svojstva, biokompatibilan je i inertan.
Međutim, zbog povećanih estetskih zahtjeva u suvremenoj dentalnoj protetici sve se više razmatra i primjenjuje cirkonij-oksidna keramika, posebice u slučajevima vrlo tanke sluznice. Zagovornici primjene cirkonij-oksidne keramike za izradu implantatnih nadogradnji navode biokompatibilnost kao glavni razlog primjene. Cirkonij-oksid ne korodira, ne izaziva alergije, bioinertan je i gladak, što je u kontroli plaka izuzetno važno svojstvo.

Abstract (english)

An effective implant osseointegration is no longer the only criterion of long-term success for prosthetic therapy. Long-term success is contingent on an adequate soft peri-implant response, in addition to the osseointegrated implant. The integration of soft tissues around the implant is one of the keys to success because soft tissues protect the bone and the implant
from bacterial penetration. The thesis is a result of a review of scientific and academic literature available in English, as selected in PubMed search by keywords including titanium, zirconium oxide, and implant abutment. It comprises papers that have been published in the past 10 years, studies involving a minimum of 10 patients, as well as studies conducted within a time frame longer than a year. The following evaluation criteria were applied: probing depth (PPD), bleeding on
probing (BOP), plaque accumulation, recession (REC), marginal bone level (MBL), and biological complications.
A review of the relevant literature shows that titanium implant abutments continue to be the gold standard. Titanium is a biocompatible, inert material with good mechanical properties. However, as a result of increased aesthetic requirements in modern dental prosthetics, careful consideration has been given to the application of zirconium-oxide ceramics which is
becoming increasingly popular, especially in cases of very thin mucosa. Proponents of the use of zirconium-oxide ceramics in the manufacturing of implant abutments cite biocompatibility as the main reason for such application. Zirconium-oxide is bio inert and smooth, which is an extremely important property in plaque control. It neither corrodes nor causes allergies.
