Tematika

The subject completes the knowledge of dental students in respect of biomaterial science as every material which is used in dentistry has to be biocompatible. Beside the traditional biomaterial classes (like metals, ceramics, polymers and composites) they will learn about hydrogels and natural materials (proteins, polysaccharides, polynucleotides). The general concepts and mechanisms of osseointegration and biointegration will be introduced at molecular and cellular level. We will discuss the newst evidences available int he field of biomaterial-host interaction and biological surface science methods (BioSS) will be presented. Implants of the oral and maxillofacial region, especially titanium dental implants osseointegration will be presented and those surface modification methods which can improve their biointegration. The etiology of peri-implant infections will be discussed and methods which van prevent them. The students will learn about biocompatibility and biomechanical tests of biomaterials (in vitro and in vivo methods).
