What is a 3D Conebeam CT machine?
Definition and Operating Principles
3D Conebeam CT is an advanced digital X-ray imaging device that uses a cone-shaped X-ray beam to create three-dimensional images of bone structures, teeth, soft tissues, and nerve pathways in the maxillofacial region with just one scan.
The operation of 3D Conebeam CT occurs in three phases:
- The operation of 3D Conebeam CT occurs in three phases:
- Phase 2: Image processing, specialized software such as I-CAT Vision is used to reconstruct a detailed 3D model.
- Phase 3: Display, cross-sections are generated in various directions to comprehensively observe the structure requiring diagnosis.

Common applications in medicine and dentistry
This technology is widely applied in many fields:
- Dental Implants: Plan implant placement with high precision.
- Orthodontics: Detailed assessment of bone structure and tooth position.
- Maxillofacial surgery: Plan detailed and safe surgery.
- Root canal treatment: Detect accessory canals and root fractures.
- Pathological diagnosis: Early detection of jaw bone lesions.
Outstanding advantages of the 3D Conebeam CT machine
Outstanding Advantages
Compared to traditional X-rays, the 3D Conebeam CT machine offers many superior benefits.
- Accuracy: Produces high-quality images with a resolution of up to 0.075mm, helping to detect the smallest details in tooth and bone structure.
- Safety: Low radiation dose (0.09 – 7.79 mSv) ensures patient safety.
- Time: Fast scanning speed (10-20 seconds), saving time and increasing patient comfort.
Comparison with other imaging technologies: conventional CT, MRI, X-ray.
Criteria | CT Conebeam 3D | CT thường | MRI | X-ray thường |
Radiation dose | Low (0.03 – 0.6 mSv) | High (2 – 3 mSv) | No radiation | Low (0.005 – 0.01 mSv) |
Scan time | 10-20 seconds | 15-30 minutes | 30-60 minutes | 1-2 minutes |
Image quality | High-resolution 3D (0.075-0.4mm) | High-resolution 3D (0.5-1mm) | Very high-resolution 3D for soft tissues | 2D, lower resolution |
Equipment cost | Moderate | Higher | Very high | Low |
Operating cost | Low | Higher | Very high | Low |
Installation space | Small (15-20m²) | Large (30-40m²) | Very large (Above 50m²) | Small (10m²) |
Observation capability | Bone, teeth, hard tissues, some soft tissues | Entire body | Soft tissues, nerves | Only bones and teeth |
Scanning position | Comfortable standing/sitting | Lying down | Lying in a narrow tube | Standing/sitting |
Dental application | Very suitable | Overkill | Disadvantages | Disadvantages |
Benefits of using 3D Conebeam CT machine in dentistry
Trong diagnosis, 3D Conebeam CT machine helps in early detection of oral diseases thanks to its ability to provide high-resolution images. This technology allows doctors to observe in detail each anatomical structure, including bone density, nerve positions, and important blood vessels.
3D Conebeam CT technology supports treatment planning with high precision down to the millimeter. This helps optimize the procedure and minimize risks during surgery, especially in complex cases such as implant placement or orthodontics.
3D Conebeam CT allows doctors to easily monitor and compare results before and after treatment, helping to accurately assess changes over time. Thanks to this, treatment plans can be flexibly adjusted to achieve the best results for patients.
3D Conebeam CT helps save costs for patients by providing comprehensive information in just one scan, instead of having to perform multiple types of X-rays. This not only reduces the number of follow-up visits but also increases the success rate of treatment, saving time and optimizing costs.
Does 3D Cone Beam CT scanning affect health?
3D Conebeam CT machine does not cause harm and is safe for patient health.
- Low radiation dose: 90% lower than traditional CT machines, ensuring safety for both children and adults, while strictly adhering to radiation safety regulations.
- Short scanning time (10-20 seconds): minimizing radiation exposure time, creating a comfortable feeling for the scanned person.
When to use a 3D Cone Beam CT machine?
During implant placement, CT Cone Beam technology plays a particularly important role.
- Before surgery: this technology helps the dentist accurately assess jawbone density to determine the most optimal implant placement. Based on detailed 3D images, the surgical team can develop a meticulous treatment plan to ensure maximum safety and effectiveness for the procedure.
- During surgery: CT Cone Beam images help the dentist precisely locate the implant placement. This not only avoids damage to important structures like nerves and blood vessels but also ensures optimal aesthetic results after restoration.
In other endodontic cases, this imaging machine is an invaluable assistant.
- Complex root canal treatment: the CT Cone Beam machine helps accurately detect additional root canals, allowing the dentist to determine the root length and comprehensively assess any surrounding damage.
- Orthodontics: the dentist can precisely locate impacted teeth, plan a safe tooth movement pathway, and closely monitor the treatment progress.
