Biological complications of the cement-retained implantsupported restorations

Abstract

Dental cements have been established in practice since 1878, and technological advances in the field of implant pros-thetics have directly influenced the development of materials in this area. Although the retention type of implant-supported restorations can be dual, it is nowadays known that the overall rate of technical complications is higher for cement-retained restorations by 2% over screw-retained restorations. Biological complications, including peri-implant mucositis, periimplantitis, bone loss around implants, soft-tissue recession and fistula suppuration, are also more frequent with cement-retained restorations. The most common of these, periimplantitis is often related to factors depending on a clinician.

Materijali za fiksiranje zubnih protetskih nadoknada utemeljeni su u stomatološkoj praksi od 1878. godine, a tehnološki napredak na polju implant-protetike direktno je uticao i na razvoj materijala u ovoj oblasti. Iako mehanizam vezivanja fiksnih nadoknada može biti dvojak, danas se zna da je ukupna stopa tehničkih komplikacija veća kod cementno retiniranih nadoknada za 2% u odnosnu na retenciju šrafom. Biološke komplikacije u koje se ubrajaju periimplantatni mukozitis, periimplantitis, gubitak kosti oko implantata, recesija mekih tkiva i pojava fistule, takođe su učestalije kod cementno retiniranih zubnih nadoknada. Najzastupljenija među njima, periimplantitis, često se dovodi u vezu sa "lekar-zavisnim" parametrima.
