Imaging tools overview
Key points
- There is a legal and ethical need to weigh the risks and benefits of imaging and radiation exposure
- It is better to refer the patient rather than perform procedures that provide incomplete imaging information
- For many implant surgeries, 3D imaging provides valuable information to assist in diagnosis and treatment planning
Main imaging tools
Because any form or radiation can impose a risk, patient history and clinical examination should be performed first to ensure that the right kind of imaging is sought and unhelpful imaging is avoided.
The four main types of imaging tools utilized, and discussed in greater detail in other sections are:
- Intra-oral radiographs
- Panoramic radiographs
- Spiral CT
- Cone beam CT (CBCT)
