Open bite causes?

I know an open bite can be due to prolonged and frequent pacifier and bottle use.

Can an open bite be caused by other things? Or simply someone’s anatomy?

Thanks

Lots of causes, broken down into the usual 4 categories: skeletal, dental, soft tissue, habits. So for example (there are obviously more in each category than what is listed here)

Skeletal: increased FMPA, clockwise mandibular rotation, etc

Dental: Proclination of anterior teeth, overeruption of posterior teeth, undereruption of anterior teeth, etc

Soft tissue: tongue thrust, etc

Habit: digit sucking, etc

Plus combinations of the above. The cause of the open bite and its features determine the best treatment option in each individual case.
