What is DVT (digital volume tomography)?
The so-called digital volume tomography (DVT) is integrated into the treatment process by arrangement with the patient in our Seehofer dental practice in order to enable an exact diagnosis of the tooth and jaw condition. It provides information about the exact course of nerve tracks and the present jaw situation of the patient. Dental implants can thus be planned precisely and a firm fit of the implants can be guaranteed. This is a so-called navigated implantation.
The 3D tomography procedure works with X-rays, but the radiation exposure is only about 1/10 of the level of conventional CT images. In addition, DVT x-rays offer the advantage that the exact jaw condition can be displayed on the computer using high-resolution sectional images.
DVT - Procedure
During the X-ray, the patient sits comfortably on a chair and does not have to lie in a tube like in a CT scan. A rotating X-ray tube rotates around the patient's head during the procedure. The DVT X-ray itself takes less than a minute. Any number of 2D and 3D sectional images can now be taken from the images, providing a particularly fast and precise basis for diagnosis.
In general, DTV x-rays have developed into an important component of implant treatments, as the entire treatment procedure can be determined more precisely. In addition, the three-dimensional images make it possible to create the templates that are used to insert the artificial implant root. In our dental practice Seehofer we also use the DTV X-ray in other dental fields. For example, for the safe removal of wisdom teeth and cysts in order to determine their exact position in the tissue.
In addition to the enormous time savings for the patient, a particular advantage is the increased transparency due to the 3D diagnostics and precise treatment planning as well as the increased safety during the implementation of the therapy.
Advantages of 3D X-ray at the dentist - radiation exposure
3D x-raying at the dentist offers various advantages, both for patients and for the dentist:
- Significantly lower radiation exposure compared to a conventional CT device
- Clear presentation of the three-dimensional images for patients
- Bone structure as well as the course of the nerve paths are visible and make precise treatment planning possible
- Particularly advantageous when inserting dental implants, as the 3D X-ray enables compatibility with other planning programs and thus the treatment can be planned precisely step by step
- Special safety for patients and dentists
