2D X-ray units Orthophos XG 3

Quality from the very start

High-quality. Durable. Safe: the Orthophos XG 3 X-ray unit is the perfect basic equipment for general dentists. The unit's easy operation and seamless integration into your practice's daily routines will save you valuable time. The high image quality and proven Sidexis software guarantees that you will reach a safe diagnosis quickly and easily. The positioning can be very easily reproduced, since image parameters such as the bite block height are saved together with the image data. A bitewing program is available, which helps in special cases and patient situations where intraoral images cannot be used and a shorter panoramic program with a reduced dose, which is suitable for treating children, is also available.

Your benefits at a glance

The perfect basic equipment for general dentists.

Feature highlights


The ASTRA software algorithm considerably improves the quality of 2D panoramic and Ceph images.


The best image quality at the lowest possible dose - following the ALARA principle.

2D panoramic imaging: revolutionary technologies

Even though 3D X-rays are increasingly becoming established in a growing number of dental practices, in many cases 2D imaging still has a rightful place, to a great extent due to radiation hygiene. It is a core component of modern dental diagnostics. In terms of improvements in image quality, the options available in 2D technology are far from exhausted.

The Orthophos XG 3 combines a premium "Made in Germany" tubehead (0.5 mm focal spot) with a CsI sensor (0.027 mm pixel size) to generate the sharpness and clarity needed for your clinical tasks. The innovative ASTRA software algorithm significantly improves the quality of 2D panoramic and Ceph images by minimizing black margins around metal fillings and getting rid of excessive contrast that could lead to misdiagnosis of caries, for example.

  • Given indications
    Adolescent, full dentition with orthodontic braces Agenesis of teeth 18 and 28 with the presence of odontoblasts in 38 and 48 The incomplete root growth in 37 and 47 as well as the root development of the two wisdom teeth are evidence of the patient's young age Maxillary sinuses and surrounding anatomical structures not radiographically apparent
  • Given indications
    Prosthetic and prophylactic treatment of dentition Hypodense clearly limited changes to the hard tooth substance in teeth 12, 11 and 22 (presumably non-x-ray-opaque composite fillings here) Hyperdense filling material in the roots of teeth 11, 36 and 35 without an indication for periapical lucency Status post apicoectomy on tooth 36 with retrograde obturation of the mesial and distal roots. Good osseous union of the apical bone tissue, no indication of recurrent periapical osteolyses
  • Given indications
    Dentition badly damaged by periodontitis, with generalized horizontal bone resorption and vertical cavities with teeth 17 – 14 requiring extraction Hypodense, homogenous and clearly delimited changes to the hard tooth substance on 12 mesial, 11 distal and 23 mesial with suspected caries or a differential diagnosis of non-x-ray-opaque composite fillings Differential diagnosis: Caries or non-x-ray opaque composite fillings PFM bridge at teeth 36 – 34 due to furcation on tooth 36 and calculus deposits mesially. Splinting of teeth 32-42 from past periodontal history Hyperdense filling material in tooth 45 without an indication for periapical lucency. Implant-based treatment in the region of teeth 46 and 47 with radiographically inconspicuous PFM hybrid bridge 45 – 47
  • Given indications
    Prophylactically treated full dentition Wisdom teeth are not present Large maxillary sinuses are visually inconspicuous The adjacent anatomical structures are also radiographically inconspicuous


What are the system requirements?

The requirements actually follow those for the image processing software, Sidexis. Details on sirona.com/SIDEXIS4-system_requirements

I already have Sidexis XG. Do I have to switch to Sidexis 4 in order to use an Orthophos XG 3 ?

No, you do not have to switch. Orthophos XG 3 works with both Sidexis XG and Sidexis 4. But for a better user experience, we recommend to install Sidexis 4, data migration from Sidexis XG to Sidexis 4 being very easy.

Can I add a Cephalometric arm on my Orthophos XG 3 later on ?

No, Orthophos XG 3 is the only Orthophos unit with no ceph capability. If cephalometric imaging may be useful to your diagnosis, we recommend you to look at the Orthophos XG 5 or Orthophos XG 3Dready.

Can I upgrade an Orthophos XG 3 with a 3D sensor?

No, Orthophos XG 3 does not allow a 3D uprgade. If 3D imaging may be useful to your diagnosis in the future, we recommend you to look at Orthophos XG 3Dready.

Are all Orthophos XG 3 units equipped with a CsI sensor?

The Orthophos XG 3 unit is equipped with a Lanex sensor as standard. The Csi Sensor is a optional feature that can be chosen when configurating the unit.
