Amelogenesis imperfecta and ceramic caps
Amelogenesis imperfecta is a hereditary condition. The teeth have fully formed roots, but enamel has not developed to cover the dentin.
We would all have teeth that look like this if our enamel didn’t form.
Creating ceramic caps that restore the missing enamel can be bonded to the dentin surfaces, but first the teeth must be separated by orthodontics because the teeth have drifted too close together.
