Question:
Full mouth restoration for ameliogenesis imperfecta: My son, who is now 16, was born with ameliogenesis imperfecta. He has veneers on his front teeth for cosmetic improvement in his appearance, and has had numerous gold crowns placed on root-canaled molars.
The teeth below the crowns are decaying, and we are now having to have the old crowns cut off and new ones put back on. Before I go to all this expense, and pain on his part, would implants with dentures be a better alternative for this kid who brushes his teeth more than anyone on the planet?
None of the dentists I took him to when we first found out he had this condition even knew what ameliogenesis imperfecta was. ... Visitor from WV
Answer:
Amelogenesis Imperfecta is a hereditary defect on the enamel as a result of an ectodermal disturbance, and therefore the inner material of the tooth called dentin is not affected.
There are three types of Amelogenesis Imperfecta which corresponds to the way that the enamel is developed.
First is called Hypolastic. This is a defect in how the organic layer of the enamel is produced and laid down over the dentin.
Next is Hypomineralization, and is where the calcification of the organic matrix is deficient in performance.
The third is called Hypomaturation... this is when the calcifying crystals fail to grow and mature
into their most hardened state.
Since the dentin is often unaffected with this condition, any of the new dentinal bonding techniques should work properly, This will allow for the placing of porcelain veneers, crowns filling and tooth colored restorations.
