To restore function (chewing function, but also aesthetics), lost bone and dental hard tissue must be replaced with various materials, mainly ceramic-based or metal-ceramic-based. The production of these highly customised prosthetic constructions required for this purpose is carried out using manufacturing processes that represent special application-specific variants of known manufacturing techniques.

This lecture provides special knowledge about the microstructure and optimisation of metallic and ceramic materials used in dentistry. In addition, special features of the production technologies and material testing methods relevant to these materials are taught.

The focus here is on acquiring the knowledge to be able to optimise the material structure according to indication and application.

1. product overview - material and indication - important properties

2. metals and alloys

2.1 Overview/definitions - metallic dental materials
2.2 Pure metals - occurrence, extraction and application
2.3. dental non-precious metal alloys (NPM) - properties, application and production of such alloys
2.4. dental precious metal alloys (EM) - properties, application and production of such alloys
2.5 Special features of the melting and solidification processes; crystallisation and segregation types

3. ceramic dental materials / dental ceramics
3.1 Overview/definitions - ceramic dental materials

3.1 Oxide ceramics
3.1.1 Manufacture and properties
3.1.2 Indication customisation through microstructure design

4.1 Silicate ceramics
3.1.1 Fabrication and properties 
3.1.2 Indication customisation through microstructure design

4 Current developments and trends

5 Metal-ceramic composite

6 Special material testing
6.1 Fracture strength (final geometry test) and biaxial strength
6.2 Colour and translucency measurement
6.3 Coefficient of thermal expansion
6.4 Adhesive bond

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

• Written examination

• Field work / Experimental work

Basic knowledge of materials technology, glass and ceramics, metallurgy, conventional and digital dental technology and manufacturing is recommended.

Students have a broad knowledge of the production, structure, properties and application of dental metals, their alloys, dental oxide and silicate ceramics and can classify the various groups.

Students have knowledge of dental alloys and dental ceramics and can describe the relationships between the structure and the resulting properties in examples.

They are able to interpret the composition of dental alloys and dental ceramics and select them according to the indication.

Based on their knowledge of the composition, requirements and properties, students can optimise the application and processing of dental materials.

Students can derive new development trends for metallic and ceramic dental materials from working with current literature.

After completing the course, students will be able to discuss practice-relevant, material-specific properties and issues with other professionals (employees in dental practices, dental laboratories or service centres) and, for example, clarify indications and interpret processing-related causes of errors and communicate avoidance approaches.

After completing the course, students will be able to justify and justify the specific requirements-related advantages and disadvantages of various metallic and ceramic dental materials in combination with the manufacturing techniques.
