The Trium is a CBCT unit that generates 3D images of the jaw and teeth with a very low dose of radiation. It’s helpful for clinicians in educating patients and motivating them to seek treatment.
What’s good about it?
This unit is easy to set up and completes scans very quickly. The patient can immediately see the results and I can explain where their implants will be placed and any risk factors. It utilises a very low dose of radiation compared to most other machines on the market.
We have it set up in a dedicated room and use it to take OPGs and Bitewing Radiographs. It’s extremely helpful when assessing root canals and tooth fractures, particularly if they’re very narrow. The whole scanning process only takes about five minutes—two minutes to set up and another minute or two for the results to appear on the computer screen.
The quality of the images is excellent and there are tools to process the image. The contrast and brightness can be changed to bring up fine details. There’s also planning software that highlights anatomic landmarks and directs the placement of implants and wisdom teeth extractions.
The patient just needs to bite on a small positional block and the scanner moves around the head. Patients with a high gag reflex have no trouble at all. When the patients come to our surgery, we can take the radiographs and provide treatment on the same day. No waiting period!
What’s not so good?
The unit can be technically sensitive for patients with disabilities where their body is not stable. While a scan can be made with a patient in a wheelchair, it’s impossible to get an accurate result if their head is not stable.
