What Is a TRIOS Intraoral Scanner?
TRIOS is a digital intraoral scanning system made by 3Shape. During the scan, a dental professional moves a handheld scanner around the teeth while the software builds a three-dimensional model of the visible tooth surfaces and bite.
A TRIOS scan is not an X-ray. It records surface information optically, while dental X-rays are used when the dentist needs information about structures that cannot be seen directly, such as areas between teeth, roots, or supporting bone.
Digital Impressions Without a Tray of Impression Material
For many treatments, an intraoral scan can replace a traditional impression. Instead of holding a tray of impression material in your mouth while it sets, the dental team scans around the teeth and reviews the digital model as it is created.
If one small area needs a clearer capture, that section can often be rescanned rather than repeating an entire impression. Many patients find digital scanning easier to tolerate, especially if they have a sensitive gag reflex, although the best impression method still depends on the procedure and clinical situation.
How Can a TRIOS Scan Be Used?
Digital impressions can support several types of dental treatment. The scan provides a detailed record of tooth surfaces, neighboring teeth, and the bite that can be used in digital planning or shared with a dental laboratory when appropriate.
Dental Crowns and Bridges
For a dental crown, the scan can record the prepared tooth, surrounding teeth, and bite so the restoration can be designed to fit the area. A similar digital workflow may be used when planning a dental bridge.
Dental Veneers
Digital impressions may also be used during planning or fabrication for selected dental veneer cases. The dentist still evaluates tooth structure, gum health, bite, and cosmetic goals before recommending treatment.
Clear Aligners
For patients being evaluated for SimplyClear clear aligners, a digital scan can create a 3D model of the current tooth positions and bite. That model can become part of the orthodontic planning process when clear aligner treatment is appropriate.
A 3D View That Makes Dental Conversations Easier
The digital model can also be useful during patient discussions. Your dental team can rotate the model, enlarge an area, and show how the upper and lower teeth relate to one another instead of asking you to imagine the shape of your teeth from a description.
The scanner does not make treatment decisions on its own. Your dentist interprets the scan together with the clinical exam, symptoms, dental history, X-rays when needed, and other information relevant to the case.
Creating a Record for Future Comparison
A digital scan can provide a record of how the visible tooth surfaces and bite looked at a particular visit. When clinically appropriate, a later scan may be referenced to help evaluate changes in tooth position, wear, or other surface features.
The way digital records are used depends on the treatment and software available. The scan itself should be viewed as one part of the overall dental record rather than a standalone diagnostic test.
What Happens During a TRIOS Scan?
The dental professional guides the handheld scanner around the upper teeth, lower teeth, and bite while the 3D model appears on the computer. You will need to keep your mouth open while each area is captured, but there is no impression material that has to harden in the mouth.
The scan itself does not involve drilling, injections, or X-ray radiation. Once the digital model is complete, your dentist can review it and use it for the treatment workflow when appropriate.
Frequently Asked Questions About TRIOS Scanning
Is a TRIOS scan an X-ray?
No. TRIOS captures visible tooth surfaces optically to build a 3D digital model. It does not replace dental X-rays when the dentist needs information about structures beneath or inside the visible teeth and supporting tissues.
Can a digital scan replace traditional impressions?
For many procedures, yes. Some treatments or clinical situations may still require another impression technique, so your dentist will choose the method that fits the case.
What if I have a strong gag reflex?
Many patients prefer digital scanning because there is no tray of impression material setting in the mouth. You still need to keep your mouth open while the scanner moves around the teeth, and the dental team can pause if you need a break.
Can TRIOS diagnose cavities?
The scanner creates a digital surface model used for dental workflows and communication. It should not be presented as a standalone cavity-detection tool. Your dentist diagnoses tooth decay using the clinical examination and any other appropriate records or imaging.
Digital Impressions at Dental Design Studios
TRIOS scanning can make it easier to capture the detailed surface information needed for many restorative and orthodontic treatments without relying on a conventional impression tray for every case. The right workflow still depends on what your dentist is treating and what information is needed.
Dental Design Studios has nine offices serving Greater Phoenix. Find a location near you to schedule an evaluation and learn whether digital impressions are part of the recommended treatment process.
