Digital technology has meant greater personalisation in our lives, including our professional life. We are no longer satisfied with being treated ‘en masse’ as the capability for modified configurations and bespoke settings are available in nearly all of the devices that we use. This capability to individualise is of great benefit in dentistry; whether it is the configuration of a dental chair for improved ergonomics, or the pre-set modes on a hygienist’s ultrasonic scaler, technology is helping workflows become simpler and quicker than ever before.
The evolution of digital radiography has put control back in the hands of the dentist by not only minimising, but also sometimes eliminating the drawbacks of conventional film radiographs. The dentist can now manipulate images that they take so they can be viewed in the way that they need to see it. With conventional radiographs, once the film had left the processing solution the image quality was determined and there was no chance of changing it. However, the quality of digital images can be altered afterwards to allow for improvements.
There are a number of factors that make up image quality. Contrast, blur and noise can be controlled with use of software to help improve the image and therefore increase the chance of better diagnosis and treatment planning. Subtraction radiography is a useful enhancement method where the purpose is to produce two radiographs of the same view but at different times. Very small changes can be seen that would otherwise have been missed on conventional radiographs or on visual clinical inspection. Another digital capability is to zoom in on specific areas of concern; something impossible with conventional film. Other common enhancement tools include changing of the brightness, enhancing contrast, reversal of the image, embossing to create the image 3-dimensionally, the use of a multi-colour spectrum and filters.
The possibilities are vast when it comes to radiograph image manipulation. The CS Adapt module from Carestream Dental offers a whole new level of choice in extraoral image processing. Whether a panoramic or cephalometric image is required, CS Adapt allows easy adaptation depending on how the clinician wants it to “look and feel” and the intuitive Filter Library allows the clinician to select up to three favourites for a seamless workflow.
Clinicians no longer have to be satisfied with using equipment that is not producing the results that they require, for the work that they do. Digitisation and the development of technology now allows for personalisation to ensure that the best results are achieved

A century later, cone-beam computed tomography (CBCT) radiography was launched in Italy by Attilio Tacconi and Pero Mozzo[ii]. The algorithm for reconstructing a three-dimensional image from a set of two-dimensional projections had been devised by L.A.Feldkamp et al in 1984[iii]. However, CBCT units specifically dedicated to dento-maxillofacial radiology experienced a fifteen-year waiting gap whilst the cost of X-ray tubes, the quality of detector systems and strength of the personal computers developed enough to catch up with the science behind them.
Since that time there has been a global explosion of digital technologies in many spheres of life. We use digital TV, radio and imaging every day, so logically, digital dentistry is fast becoming the norm. More than 50% of dentists using digital technologies report an increase in earnings, and 93% claim they have significantly improved patient experience[iv].
It is only in recent times that CBCT clinical systems affording 3D data have been relatively inexpensive and small enough to be used in dental practices[v]. The advantages of this are infinite, especially within the fields of periodontology, endodontics and implantology. In these disciplines, CBCT 3D scanning is indispensable; the view of the teeth in context, with the surrounding bone and tissue is crucial to release full diagnostic potential and provide greater precision in the selection and placing of implants. Additionally, the cone beam technique uses a single scan capturing the entire area, vastly reducing the amount of exposure time to the patient.
The CBCT digital system allows for clinicians to explain treatment options and provide a virtual presentation of these processes in advance. Implants can be placed on an accurate and high resolution CBCT scans and the digital guides ordered. This guides then help in the precise positioning of the implant. Some practices even have the necessary equipment to take X-rays and mill guides in one sitting.
Carestream Dental, a leader in the arena of digital imaging, offers an exceptionally user-friendly CBCT solution in the CS 9000 3D extraoral imaging system. 3D technology combines panoramic imaging in one, affordable unit. The cone beam limits radiation to a specific oral site, offering the lowest possible radiation dose. Provided with innovative CS 3D imaging software, the unit aids with treatment planning and patient communication using visuals in slice by slice, axial, coronal, cross-sectional and oblique views. What’s more, the integration of the CS 3500 Intraoral Scanner with the Dicom volumes from the CBCT, provides all the information required for guided surgical stents.

Enabling you to effortlessly integrate your conventional radiographic diagnostics with powerful digital technology, the XIOS Scan consists of two main components: the scanner and the imaging plates.
These imaging plates are suitable for any patient, and because they have been specifically designed, you can be certain of exceptional image quality every time.
After exposure, the plates are inserted into the XIOS Scan itself, where thanks to an outstanding scan quality of up to 22 line pairs/mm, you are presented with extraordinarily sharp digital radiographs, sent directly to your computer. The automatic plate detection will also ensure that the first scan you take will be the only one you need.
With this cutting-edge solution, you will be able to easily digitise traditional radiographs without having to working with environmentally harmful chemicals ever again.
If you want to take advantage of all the benefits of digital radiographic technology, without having to disrupt your tried-and-tested diagnostic workflow, consider the Sirona XIOS Scan, available from Clark Dental, today.

“The Nomad Pro 2 handheld X-ray machine is great for our practice. The beauty of it is that we can walk around and there is no clutter on the walls – just one fully mobile machine.
“The advantage to us is that radiographs do not have to be taken in only one X-ray room as before. We can move around across multi-surgeries and so our patients don’t have to, which helps them to feel more at ease. As it’s handheld the practitioner can work around the patient much more freely, ensuring they get the most appropriate radiographs.
“The images quality is great too, and perfect for our practice needs.”
To learn more about the fantastic Nomad Pro 2, and the benefits it will bring to your practice contact the Clark Dental team today.
