Traditional crown workflows commonly use impression material to create a physical mold of a prepared tooth. Digital dentistry takes a different approach, using an intraoral scanner to create a digital 3D representation of that same tooth instead.
At Coastal Connecticut Dentistry, the CEREC workflow follows a digital path from start to finish: digital imaging, digital impression, CEREC design, in-office milling, and placement. Keeping crown information in a digital format throughout changes how that information is captured, reviewed, and used to design the final restoration. For patients in Waterford, CT weighing a CEREC crown, understanding what a digital scan actually captures and what happens to that information helps explain why this workflow looks different from a conventional one.
What Is a Digital Dental Impression?
A digital dental impression is a computerized representation of the prepared tooth, the adjacent teeth, the surrounding anatomy, and opposing bite information, captured through intraoral scanning rather than conventional impression material.
Instead of a physical mold, an intraoral scanner performs a dental scan that creates a 3D digital model you can review on a screen. This digital scan for a crown becomes the foundation for everything that follows in CEREC crown design.
How Traditional Dental Impressions Are Made for Dental Crowns
Traditional impressions use a soft material placed in a tray, which sets around the prepared tooth to create a physical impression. That impression is then used to create a model, which becomes part of the workflow for fabricating the final restoration.
Depending on the technique and the skill of the dentist, traditional impressions can provide excellent clinical results. This method has a long, established track record in restorative dentistry.
Why Traditional Impressions Can Still Produce Accurate Crowns
Traditional impressions are a well-established clinical method, not an outdated one. The difference between digital and traditional approaches isn’t that one is accurate and the other isn’t.
Instead, digital scanning changes how information is captured, reviewed, transferred, and incorporated into CAD/CAM design. Both approaches, when done well, can produce a crown that fits and functions properly.
Digital Scans vs. Traditional Impressions: What Is Actually Different?
| Attribute | Digital Scan | Traditional Impression |
| Data format | Digital 3D model | Physical impression/model workflow |
| Capture method | Intraoral scanner | Impression material |
| Review | Digital visualization | Physical inspection |
| Retakes | Areas may be rescanned where workflow permits | Impression may require repeating |
| CAD/CAM integration | Direct | Additional workflow may be required |
| Patient experience | No full conventional impression tray for scanned area | Impression material/tray may be used |
| CEREC integration | Direct digital workflow | Not the core CEREC chairside workflow |
Neither approach is inherently superior across the board. Each has a different information pathway, and that pathway is what actually changes between the two methods.
How an Intraoral Scanner Captures a Tooth for a CEREC Crown
The value of an intraoral scan comes down to what information it actually captures, and how that information gets used.
Scanning the Prepared Tooth
The scanner performs a digital crown scan of the remaining tooth structure after preparation, capturing the preparation geometry and the visibility of the finish line, or margin. This CEREC scan becomes the starting point for the digital crown design that follows.
Capturing the Crown Margin
The crown margin is the transition point where the restoration meets the prepared tooth. Clear capture of this margin, or finish line, matters because it directly informs marginal fit, how well the final crown achieves marginal adaptation, and how well it forms a proper crown seal.
Scanning does not guarantee a perfect margin on its own. What it does is give the dentist a detailed digital view of the margin to evaluate before the crown is ever designed.
Scanning Neighboring Teeth
Adjacent teeth provide information the dentist needs for proximal contacts, crown width, tooth position, and contours, all of which affect how well the new crown integrates into the arch. Without this data, a crown could be designed in isolation, disconnected from the teeth around it.
Capturing the Opposing Teeth and Bite
The digital workflow can also incorporate opposing tooth and bite information, capturing the occlusion, chewing surface, and crown height needed for the restoration to function correctly. This bite data matters just as much for a digitally scanned crown as it does for any other, since a crown that doesn’t account for the opposing arch can affect how your bite comes together once it’s placed.
How Digital Scan Data Becomes a CEREC Crown
Once the scan is complete, that information moves through a specific sequence to become a finished restoration.
Step 1: Create the Digital Impression
The scanner captures the mouth and creates the digital representation that replaces a traditional physical impression.
Step 2: Build a 3D Model of the Tooth and Surrounding Bite
The scan information is used to build a digital working model of the prepared tooth along with the surrounding bite, giving the dentist a complete picture to design from.
Step 3: Design the Crown With CAD/CAM Technology
Using CEREC’s CAD/CAM system, the software shapes the crown’s anatomy, contours, contacts, dimensions, and bite relationship based on the 3D model.
Step 4: Mill the Crown From Dental Ceramic
The digital design becomes a physical restoration through CEREC milling, where a milling unit shapes the crown from a block of dental ceramic. This chairside crown fabrication is what allows a CAD/CAM crown to be milled and completed in-office as a finished, milled ceramic crown.
Step 5: Evaluate, Customize, and Place the Crown
Software does not automatically create a perfect restoration. The dentist still evaluates fit, contacts, bite, appearance, and overall clinical acceptability before the crown is placed. This step is where clinical judgment, not the technology alone, determines the final result.
How Digital Scanning Can Support Precise Crown Margins
Clear digital visualization may help the dentist evaluate a captured preparation margin before moving forward with crown design. Seeing the margin boundaries clearly on a screen, sometimes with digital magnification, supports more informed restoration design and better crown margin accuracy.
This can contribute to precise crown fit and better marginal adaptation, though no scan can promise a perfect fit on its own. The scan is one part of a process that still depends on the dentist’s evaluation and the crown’s design.
How Digital Scanning Helps Plan Contacts Between Teeth
Proximal contacts, the points where a crown touches the teeth next to it, matter more than many patients realize. Poor contact can lead to food trapping, flossing difficulties, or other functional issues over time.
Because digital crown design incorporates adjacent-tooth anatomy directly from the scan, the crown’s contour can be planned with these neighboring contacts in mind from the start, rather than adjusted afterward.
How Digital Scanning Helps Plan the Crown’s Bite
A crown has to interact correctly with the opposing arch, not just fit the prepared tooth. The scan and design workflow can provide information used to plan crown height, occlusal anatomy, and opposing contacts before the crown is milled.
That said, final clinical bite verification still has to happen in person. Digital planning informs the design, but it doesn’t replace the in-person check that confirms the bite actually feels right once the crown is in place.
Are Digital Dental Impressions More Accurate Than Traditional Impressions?
Not automatically, and not universally. Both digital scanning and traditional impressions can produce clinically successful restorations when done well.
Digital scanning does offer some practical advantages: immediate visualization of the captured area, the ability to assess scan data before proceeding, direct CAD/CAM integration, fewer physical transfer steps in the workflow, and the option for targeted rescanning where needed. But accuracy with either method depends on several factors, including the scanner used, the technique, the tooth preparation itself, visibility, moisture control, the specific clinical situation, and the operator’s experience.
In other words, the method is only one variable among several that determine how accurate the final impression is.
Why Digital Impressions Can Be More Comfortable for Patients
Digital scanning can avoid the experience of a conventional impression tray and material for the scanned area, which is a meaningful benefit for some patients. Concerns like a strong gag reflex, the feel of bulky trays, or general discomfort with impression material are common reasons patients find intraoral scanning easier to tolerate than a traditional mold.
For patients specifically looking for comfortable dental impressions, this is a real, practical benefit, though it’s a supporting advantage rather than the main reason digital workflows matter for crown design.
Can a Dentist Correct a Digital Scan Before Designing the Crown?
Yes, in general, digital workflows allow the dentist to review captured areas and rescan specific spots if more information is needed, before the crown design process begins. This works differently from a physical impression, where a problem area typically means retaking the entire impression rather than just one section.
This isn’t a criticism of traditional impressions. It’s simply a different way of handling the same sequence both methods rely on: capturing the information, inspecting it, validating it, and using it to design the crown.
Does Digital Scanning Mean a CEREC Crown Will Fit Perfectly?
No. No technology, digital or otherwise, guarantees a perfect restoration.
Crown outcomes still depend on accurate diagnosis, careful tooth preparation, proper moisture control during the scan, scan quality, thoughtful restorative design, appropriate material selection, precise milling, careful finishing, secure cementation or bonding, and final bite verification. A digital scan is one input into a longer clinical process, not a shortcut around it.
Digital Scanning and Same-Day CEREC Crowns: Why the Workflow Is Faster
Digital scanning does contribute to a faster overall process. The scan creates the digital model, which feeds directly into CAD design, which feeds into in-office milling, allowing many cases to move to same-day placement without sending anything to an outside lab.
At Coastal Connecticut Dentistry, this same digital imaging, CEREC software design, and in-office milling process is what makes same-day treatment possible for many patients. You can read more about same-day CEREC crowns and what makes same-day treatment possible, so this article keeps that part brief.

Digital dentistry here means your crown information stays in a consistent digital pathway from the first scan through final placement.
Frequently Asked Questions About Digital Dental Impressions and CEREC
Are digital impressions more accurate than traditional dental impressions?
Not automatically. Both methods can produce accurate, well-fitting crowns, and accuracy depends more on technique, preparation, and clinical factors than on the method alone.
How long does a digital scan for a dental crown take?
Scan time varies depending on the tooth being scanned and the specific case, so there isn’t a single fixed duration that applies to every patient.
Does an intraoral dental scan hurt?
No. A digital scan is generally comfortable, since it uses a small handheld wand rather than impression material or a bulky tray.
Do I still need dental impressions with CEREC?
In a sense, yes. A digital scan is itself a type of dental impression, a digital one, that replaces the traditional physical mold for the scanned area.
Can digital scanning improve crown fit?
It can support more informed crown design by giving the dentist clear visualization of the preparation and surrounding teeth, though it doesn’t guarantee a specific outcome on its own.
Can a digital scan capture my bite?
Yes. The digital workflow can incorporate opposing-arch and bite information, which helps inform how the crown is designed to interact with your bite.
Does digital scanning eliminate temporary crowns?
In suitable cases, same-day CEREC treatment can eliminate the need for a temporary crown, since the permanent restoration is designed and placed in one visit. This isn’t the case for every situation, since some patients still require a staged approach.
