Why do we record centric relation?
The reason centric relation is so important is because it is the highest possible position of the condyle- disc assemblies that is achieved by coordinated muscle activity when the jaw is closed. At this uppermost position, the jaw joints are seated firmly against a bony stop so they cannot go higher.
How do you record centric jaw relations?

What is centric relation used for?
Centric relation is the most retruded, unstrained position of the mandibular condyle within the temporomandibular joint (TMJ), that is, within the glenoid fossa. Ideally, in centric occlusion the condyle sits anatomically within the glenoid bilaterally, reflecting simultaneous centric occlusion and centric relation.
