Test Methods with Special Reference
to Nanostructural Chemically Bonded
Bioceramics
This chapter gives an overview of the most critical test methods used
for determining important properties for nanostructural chemically
bonded bioceramics (CBBCs). The test methods dealt with in the
chapter comprise nanostructural evaluation, including contact zone
determination and mechanical strength and dimensional stability
evaluation. Test methods related to chemical stability, microleakage,
biocompatibility, bioactivity, anti-bacterial properties, and others
will be treated in relation to examples of nanostructures and
properties in Chapters 7 and 8.
5.1 Introduction
When evaluating new biomaterials it is very important to know and
understand the relationship between the new material, the specific
test methods used, and what application the material is intended
for. Often according to standards the methods are established
and decided related to specific early commercially introduced
biomaterials. A new material may be a good choice for a given
application but can exhibit problems related to the test method.
As an example, for a chemically bonded ceramic material based on
Ca-aluminate, testing at body temperature or at least above 30°C
