Case of the week: Fusion 3


This week is a neat case of fusion with some clinical photos as well.  Fusion is when two adjacent developing teeth fuse into one large tooth.  This results in an overall tooth count of 15 for an arch.  Gemination, which can have a similar appearance, results in an overall tooth count of 16 for an arch.  This case involves a maxillary first and second molar that fused together into one huge tooth.  Check it out.

Fusion is more common in the anterior region; hence this is a really neat case.  If you have any questions, please feel free to ask in the comments below. Thanks and enjoy!
