Werkstoffe für die Zahnheilkunde

Abstract

Zahnärztliche Werkstoffe werden heute in der Öffentlichkeit in breitem Rahmen diskutiert. Nach einem Überblick über Arten und Eigenschaften moderner zahnärztlicher Werkstoffe wird sowohl auf Werkstoffe zum Füllen kariöser Zähne als auch auf solche zum Überkronen oder Ersetzen fehlender Zähne eingegangen. Fragen der Verträglichkeit und Biokompatibilität werden nicht behandelt.

Corrosion of nonprecious metal alloys in dentistry in the presence of common saliva additives

“…These materials have numerous advantages when compared with other materials like synthetic polymers or ceramics. [ 1 ] They can be manufactured by well‐established procedures like casting [ 2 ] into very precise and highly developed shapes for application as inlay, onlay, filling, and so forth. They are also frequently used as mechanical support structures for partial and complete dentures.…”

“…This has resulted in the use of noble metals, in particular, of gold and of alloys with high cold content, in dentistry. [ 1 ] For specific applications (crowns, inlays), financial expenses related to the use of gold and its alloys has grown to an extent not acceptable to healthcare systems in various countries, already in the 80s. This has resulted in the development of less expensive materials, for example, palladium‐based alloys.…”
