A premature contact that occurs when the mandible closes with the condyles in their optimum position is called what?

Explanation:
When the jaw closes with the condyles in their optimum position, the teeth should meet smoothly in centric relation. A premature contact in that position is called a centric occlusal interference because that contact disrupts the smooth seating of the teeth right at the start of closure in centric relation. It’s different from occlusal trauma terms, which describe tissue injury from excessive forces rather than the timing of contacts. So the best label for a premature contact occurring during centric relation is centric occlusal interference.
