The Sharp Layer (SL) Technology


The Sharp Layer technology produces X-ray images in which the entire jaw is automatically shown in the sharp layer, taking the patient’s individual anatomical features into account. For a panoramic image, the Sharp Layer technology uses several thousand individual projections that are taken very rapidly from several angles in one rotation and reproduce the individual morphological situation very precisely.

The advantages: Excellent panoramic images and the possibility of compensating for positioning errors retroactively. The automatic Sharp Layer technology adapts the sharp layer intelligently and automatically, eliminates the necessity for the advance selection of jaw morphology and front tooth position, and thus simplifies the operation of the X-ray device. In addition, the interactive Sharp Layer technology makes it possible to shift the depth of focus retroactively in bucco-lingual direction, so that it can be detected immediately which structure is in front and which is behind in case of unclear superimposition.

Sharp Layer is the technology that gave the Orthophos SL its name. But it is not the only technical feature aimed to improve image quality. The goal of the Orthophos SL is to provide the best possible imaging solution and impress even the most demanding dentists around the world.

Low Dose: CBCT in a 2D Image Dose Range

Indication-based diagnosis using CBCT images in the same dose range as 2D X-ray images is now possible with the Low Dose mode. It‘s optimized pre-filtering preserves dense structures such as bone even at a highly reduced dose, so it can be used easily and efficiently in many specialist fields, for example, orthodontics or implantology.

Your practice will be even more flexible, because depending on the patient case you decide: whether to use your Orthophos SL to obtain high-resolution, focused volumes for the finest of structures (HD), balanced images for general questions (SD), or Low Dose imaging for minimum radiation doses


While working with children an extra level of caution is of essence. Nevertheless, there will be cases in which 2D imaging just cannot supply the necessary information. With the low dose mode now both worlds can be combined: the low dosage level of a panoramic image to protect the young patient and the information level of a CBCT image for the best treatment.


Even with the best planning and the best treatment, you still want to be absolutely sure your implantation was a complete success. Only a CBCT image can supply the necessary information to be 100% certain, but is the dose worth the benefit? With low dose: yes. You can assure your patient that everything went well at the dose level of an intraoral scan.

Sleep apnea therapy

Many dental practices see them every day: patients with all the typical indications of sleep apnea. With low dose, you now have the perfect assistance for your sleep apnea treatment with SICAT Air. A low dose 11 x 10 cm will show you exactly the upper airways and where the problem lies, with the click of a button you can then order a SICAT OPTISLEEP therapeutic appliance.

DCS: a comparison

The image shows X-ray images with and without DCS technology. Move the control over the image and see for yourself the difference the DCS sensor makes to the image quality.

 Safe Diagnosis with High Definition Mode

There are situations, including surgical interventions, when a greater radiation dose is necessary to achieve better diagnostic accuracy. Users now have an optional high-definition (HD) mode for precisely these cases.

In HD mode, Dentsply Sirona 3D devices generate 800 instead of 200 individual images, which are then used to create the X-ray image. With the Orthophos SL for example, the resolution of the images is increased to 80 μm and practitioners obtain low-noise, high-contrast images, even in complex cases. This allows for a faster and more reliable diagnosis of the imaged volume. The touch panel of the devices enables the HD mode to be switched on or off at any time
