Are there other anatomic areas of common concern when having implants placed?
Yes, the maxillary sinus. This is the large cavity in the area above the maxillary (upper) molars. It sits under the eyes, behind the cheekbones, and to the right and left of the nose. Its the space that fills with mucous when we have a cold. The reason the maxillary sinus is a concern during implant placement is that it is hollow. If its hollow, it cant support anything. Imagine being able to place a pencil through an empty egg. Once the point is on the inside, the thin eggshell wall offers no support to hold the pencil rigid. The pencil will move. The same happens with an implant.
