Diagnostic CT scans are useful for a variety of reasons:
- To check a patient’s suitability for dental implants
- To check bone depth, width and density prior to placement of implants.
- To find the best location to place an implant, avoiding sinuses & nerve canals.
- To have a 3-D view of the sinus cavities, to assess the need for sinus lifts.
- To detect vertical root fractures that may not be visible on an OPG.
- To check the proximity of an impacted 3rd molar or other tooth to the nerve canal.
- To investigate damage done during previous root canal treatment.
Diagnostic CT scan images are supplied to referring dentists, burnt onto a CD and can also supplied with the necessary software to make them fully readable on any reasonably modern computer.
No preparation is necessary for an echocardiography.
