What is it?
3D Technology is a new Computerised Tomography technique dedicated to the study of the facial skeleton; in particular, the dental arches when programming and scheduling implantology interventions.
Cone beam technology uses a cone-shape x-ray beam, which allows acquirement of a large volume with noteworthy reduction of the dose of radiation to which the patient is exposed with respect to conventional CT systems.
Why is it performed?
The main application is in the field of implantology in order to assess morpho-structural characteristics, the height and thickness of the alveolar bone in the areas affected by the implant.
It is useful in oral and maxillofacial surgery in the pre-operative evaluation of impacted teeth and, in particular, of the third molars for the exact definition of relations with the mandibular canal.
Thanks to the particular programs, it is possible to “colour” the mandibular canal to better define the relations with the impacted tooth.
Thanks to the low dose of exposure, it is also used in some cases in endodontics-periodontics: with the use of 3D cone beam technology, a more detailed view is given, quicker and more accurate diagnosis can be performed and therefore more successful results are obtained.
It also allows the temporomandibular joints to be studied with an excellent three-dimensional representation.
Thanks to the wild field of view of the equipment in use in our Centre, the CONE BEAM TC is also applied in dentistry.
Due to three-dimensional acquirement (3D) it is possible to obtain additional information and anatomic details with respect to what can be obtained from the dental scan, which is however, a two-dimensional representation (2D).
Various types of images can be reconstructed from the volume acquired, such as reconstructions of panoramic and cephalometric x-rays.
New diagnostic possibilities are therefore presented, also in the field of dentistry.
Another possible field of application is in the ENT ambit, especially for children, as the reduction of the dose with respect to a conventional CT is more significant and therefore with low doses of radiation it is possible to study the facial skeleton and, in particular, the nasal cavity and the paranasal sinuses.
How is the examination performed?
The examination takes just a few seconds and can be comfortably carried out standing or sitting down.
The cone beam tomograph looks like an orthopantomograph. The patient can be positioned very easily, in a similar manner as for a common orthopantomography examination of the dental arches; this examination
What are the benefits?
The 3D cone beam volumetric CT system uses technology dedicated to the study of the cranio-facial area and, in particular, implant surgery. Programs dedicated to this branch of dentistry have therefore been developed.
The images obtained can be used by the software dedicated to assisted surgery, which have been developed by the leader companies (Nobel Guide, Materialise Simplant, Sirona Sicat etc.).
An implant simulation program is also available with the possibility of drawing the mandibular canal and positioning the implants in order to plan treatment.
Thanks to volumetric acquirement using a cone-shape x-ray beam, there is drastic reduction of the dose to which the patient is exposed (approx. 30-60 times lower than a conventional TC).
The examination is performed in just a few seconds while standing or sitting, if necessary.
The equipment used in our Centre also has an innovative program called Face Scanner, which allows the facial surface, with accurate and chromatic representation of the soft tissue, to be recorded simultaneously to acquirement of the skeletal structures and teeth.
This means the patient can be shown a simulation of what the results and changes to the facial surface can be following the proposed surgery in advance.
The patient can thus more easily understand the possible results of treatment through the representation of his own face on the screen.
