Making accurate dental impressions is easily the most essential part of submitting a case. There are many different options out there for capturing dental impressions, from traditional impressions to the wide variety of intraoral scanners available on the market today.
3-D technology has had a significant impact on dentistry in the last 20 years, and it is only expected to increase in the coming years. More and more doctors are moving over to intraoral scanners.
We thought that a tip covering intraoral scanning with ClearCorrect might be helpful, whether you already use an intraoral scanner or if you're considering one.
A study from 2014 found that the use of intraoral scanners could significantly accelerate the work flow of making impressions.
Some benefits of using an intraoral scanner include:
- More comfortable for patients than conventional impressions
- Save costs on impression materials
- No shipping hassles
- Higher accuracy than traditional impressions
- Fewer errors resulting in having to re-impress
- Facilitates sending scans to ClearCorrect electronically, resulting in a faster turnaround
ClearCorrect accepts records from most intraoral scanners currently on the market.
With the wide variety of intraoral scanners available, selecting the best intraoral scanner for you really comes down to your preferences. Some things you might want to consider when choosing a scanner:
- Is the scanner portable?
- Is the scanner light and easy to use?
- Will the scanning experience be comfortable for patients?
- Is there a cost for image export and storage?
- Is the software for the scanner compatible with your practice management software?
Submitting a case to ClearCorrect with scanners
You can upload scan files from any intraoral scanner to ClearComm as long as the file is in STL format. (STL is an open, industry-standard file format that can be exported by most popular scanners.) Export your STL files from your scanner to your computer, and then upload those files just like your photos when you submit a case online, or on the case page after submitting.
STL files are not necessary if your scanner has the option to select ClearCorrect as your dental lab and upload scans directly from the scanner. CEREC Connect and TRIOS currenty offer this option.
We provide instructions for some of the common scanners:
Model or impression scanners
We also accept scans from model or impression scanners like Motion View's Ortho Insight 3D Scanner. Whether you're using an intraoral scanner or a model or impression scanner, ClearCorrect works with your team to accept digital files enhancing productivity and quality.
Here are a few tips for using scanners:
- We strongly recommend that you visually inspect your STL files before you submit them to us. We recommend netfabb Studio Basic, which is available free for Windows, Mac, and Linux. Other STL viewing options include viewstl.com, MiniMagics and FreeCAD.
- Some scanners output several files, but the only files we want are the upper and lower arches. The arches should be saved in separate files, with the arches oriented in occlusion.
- Scan both arches, even if you're only treating or revising one of them. Recreating the occlusion based on one arch is prone to error. (This advice applies to PVS impressions as well.)
- We prefer "closed shell" models, but "open shell" models are acceptable too.
- To prevent aligners from flaring at the edges, always capture at least 3-5 millimeters of gum in the scan.
- While bite registrations are no longer a requirement for submitting PVS impresions to ClearCorrect, this is still part of the workflow with some scanners. You can capture more accurate bite scans by including as much of the occlusion as your scanner allows.
- We can't provide support for your scanner software, but if you have any other questions, as always, our knowledgeable support reps are here to help.
