In dentistry, we are dealing mostly with the maxillary sinuses, and because everyone’s sinuses have different shapes and sizes it is crucial to get an exact measurement before any procedure is started. Every sinus is given a 3-D scan in order to determine the individual patient’s problem. It is highly important to avoid placing dental implants into the sinuses, so depending on where the implant needs to go there may be a need for a graft in order to create a stable anchor.
