NewTom GiANO HR DC: a 3D view to prepare your implants
Face Clinic is equipped with the NewTom GiANO HR DC, a 2D and 3D dental imaging system. Its CBCT (3D scan) — or cone beam — examination allows the bone structures to be studied in three dimensions to prepare a prosthetic rehabilitation on implants.
Planning implants around your future teeth
To replace one tooth, several teeth or rebuild an arch, the prosthetic plan and the anatomy must be considered together. The CBCT (3D scan) assessment helps to:
- measure the height and width of the available bone at the planned sites;
- locate the mandibular canal, neighbouring roots and maxillary sinuses;
- assess the need for a bone graft or sinus lift ;
- plan the position, angle and dimensions of the implants in relation to the future prosthesis.
This data can be combined with digital impressions and the prosthetic plan in the planning software. It is used to prepare guided or navigated surgery when indicated.
High definition and adapted acquisition
The GiANO HR platform offers several fields of view and image quality levels. The area examined and the settings are selected according to the clinical question, rather than always using the largest field or the maximum resolution.
The DC — direct conversion technology concerns the detector for 2D examinations, such as panoramic and cephalometric X-rays. It converts X-rays directly into digital signals; it is separate from 3D CBCT (3D scan) volume acquisition.
CBCT (3D scan) versus a conventional medical CT scan: what is the benefit for your treatment?
For a dental bone assessment suited to its indication, CBCT (3D scan) generally involves lower X-ray exposure than a conventional medical CT scan.
This difference is not a fixed percentage, however: it depends on the device, the volume examined, the resolution and the settings. Some medical scanners also have low-dose protocols.
Low dose: optimising exposure, keeping the useful information
The device combines several ways of controlling the dose:
- SafeBeam™ automatically adapts the exposure to the patient’s anatomical characteristics.
- Pulsed emission limits the X-ray emission time during 3D acquisition.
- ECO Scan mode allows reduced-dose acquisitions when the level of detail meets the clinical need.
- A targeted field of view limits the irradiated area to what the examination requires.
The protocol is chosen to obtain the necessary diagnostic information with optimised exposure. A detailed implant assessment may require a mode other than ECO Scan. The dose depends in particular on the field examined, the protocol and the patient: “low dose” does not mean no radiation.
Radiation protection is part of your care
At Face Clinic, the aim is to gather the information needed for implant planning while avoiding unnecessary exposure. This means justifying each examination, taking existing images into account and adapting the field and settings to your situation.
CBCT (3D scan) uses X-rays and generally involves more exposure than a 2D dental X-ray. It is used when its diagnostic value justifies it. Safety relies on this balance between clinical benefit and optimised exposure.
