Digital impressions have transformed how dentists capture the shape and position of teeth and oral tissues. Rather than using traditional impression trays and putty, modern intraoral scanners create a precise three-dimensional digital model that can be reviewed instantly on a monitor. This page explains what digital impressions are, how they work, and why many patients and clinicians prefer them for restorative and cosmetic care. The explanations below are written for patients who want a clear, practical understanding without unnecessary jargon.
Digital impressions begin with an intraoral scanner — a handheld device that records a series of high-resolution images or a continuous video of the teeth and gums. As the scanner moves through the mouth, specialized software stitches these images together into a detailed 3D model. The process is non-invasive and avoids the taste and gagging that can accompany traditional impression materials.
Scanners use different technologies — such as structured light or confocal imaging — to measure surface contours and undercuts with great accuracy. The operator can pause and review the scan in real time, allowing immediate corrections if an area needs rescanning. This instant feedback reduces the need for repeat appointments or delayed laboratory work caused by inadequate impressions.
Once the scan is complete, the digital file can be refined and prepared for the next step in the workflow, whether that’s sending the model to a dental laboratory, designing a restoration in-house, or integrating with other digital data such as cone-beam CT or intraoral photography. The entire capture process typically takes only a few minutes longer than a routine exam, depending on the scope of the case.
One of the most noticeable differences for patients is comfort. Digital scanning eliminates the need for bulky trays and impression putty, which some patients find uncomfortable or anxiety-provoking. For people with sensitive gag reflexes, limited mouth opening, or claustrophobia, digital impressions are often a much more tolerable option.
The speed of the process is also an advantage. Scans can be completed quickly and reviewed immediately, reducing chair time and streamlining visits. Patients appreciate seeing the 3D images on screen; visualizing their own teeth helps clinicians explain treatment needs and proposed restorations more clearly than with a static description alone.
From an infection control perspective, digital impressions remove the physical impression from the chain of handling, packaging, and shipping. Because there’s no physical impression tray to disinfect or transport, the workflow can be simpler and cleaner while still meeting clinical and laboratory requirements.
Digital impressions offer a high degree of precision that supports successful outcomes for crowns, bridges, inlays, onlays, and implant restorations. The ability to capture detailed surface anatomy and occlusal relationships in three dimensions improves the fit of restorations and reduces the likelihood of adjustments or remakes. Many clinicians find that digital files produce predictable, repeatable results when used with established digital protocols.
Because scans are reviewed immediately, the clinician can identify and correct any areas with incomplete data while the patient is still in the chair. This reduces the risk of sending imperfect impressions to the laboratory and minimizes the need for follow-up appointments caused by poor fits. When combined with digital design tools, the workflow supports precise margins, contacts, and occlusion.
Digital models can also be archived indefinitely without physical storage space, making it easier to track changes over time or retrieve original data for future care. This long-term digital record can be useful for complex restorative planning and for coordinating care with specialists or dental laboratories.
One of the strongest practical benefits of digital impressions is accelerated turnaround. Files are transmitted electronically to dental laboratories or to in-office milling systems, eliminating shipping delays and reducing lead times. For labs that work digitally, this direct transfer often results in faster production of restorations with fewer intermediate steps.
Digital workflows also enable same-day restorative options when combined with chairside milling and ceramic systems. In-office CAD/CAM systems can take a digital impression, design a crown or onlay, and mill a final restoration during a single visit. That integration enhances convenience for patients who prefer fewer appointments and quicker treatment completion.
Beyond production speed, digital impressions improve communication between the clinician and the dental laboratory. Technicians can view and manipulate the same 3D model, annotate areas of concern, and collaborate on design choices. Clear digital communication helps align expectations and can lead to fewer adjustments at insertion.
Digital impressions are used across a wide range of restorative and cosmetic procedures. They are suitable for single crowns and bridges, implant abutments, veneers, and complex full-arch rehabilitations. For implant cases, digital scans can be merged with CBCT data to support guided surgery and restorative planning, improving accuracy from implant placement through final restoration.
Orthodontic and cosmetic planning also benefit from digital models, which facilitate treatment simulations and communication about anticipated outcomes. Clear aligner workflows commonly rely on digital impressions to produce series of aligners that match the patient’s existing anatomy and treatment objectives.
Because the digital file can be shared instantly with specialists, laboratories, or imaging services, coordination of care becomes more efficient. Whether the treatment path involves an in-house CAD/CAM restoration or a trusted laboratory partner, digital impressions support a smoother collaboration and help maintain consistent quality throughout the process.
In summary, digital impressions modernize the traditional impression process by improving comfort, accuracy, and workflow efficiency while supporting a wide range of clinical applications. At ProSmiles OC, we incorporate digital scanning into restorative and cosmetic procedures to enhance predictability and patient experience.

Digital impressions are three-dimensional virtual models of the teeth and surrounding soft tissues created with an intraoral scanner. Instead of filling trays with impression putty, a handheld scanner captures a series of images or a continuous video that specialized software stitches into a precise 3D model. This process produces an immediate, reviewable file that replaces a physical cast for many restorative and cosmetic procedures.
Traditional impressions require trays, impression material and laboratory casting, which can be uncomfortable and require additional handling. Digital files remove the physical impression from the workflow and can be transmitted electronically, archived indefinitely and integrated with other digital records. The result is a modern alternative that emphasizes accuracy, convenience and simplified logistics for clinicians and patients.
An intraoral scanner uses a handheld wand that records high-resolution images or continuous video of the teeth and gums while the operator moves it through the mouth. Specialized imaging technologies such as structured light or confocal imaging measure surface contours and undercuts, and software aligns the captured frames into a single 3D model. The clinician can watch the reconstruction in real time and pause to rescan any area that needs additional detail.
The scanning session is noninvasive and typically takes only a few minutes longer than a routine exam, depending on the extent of the arch being recorded. Because scans are generated digitally, they can be electronically refined or exported in standard file formats for laboratory or in-office design. This live feedback loop reduces the chance of incomplete data and minimizes the need for repeat appointments.
Many patients find digital impressions more comfortable than traditional trays and putty because the process eliminates bulky materials in the mouth and reduces gagging or anxiety. The scanner is compact and designed for easy access to all tooth surfaces, making it suitable for patients with limited mouth opening or a sensitive gag reflex. Scanning is fast, and clinicians can address patient comfort during the procedure by pausing as needed.
From an infection-control standpoint, digital impressions reduce the number of physical items that require handling, disinfection and shipping. The digital workflow limits the chain of contact associated with impression materials and trays while still meeting clinical and laboratory requirements. Clinicians continue to use standard sterilization protocols for any intraoral devices that enter the mouth.
Digital impressions provide a high level of accuracy that supports precise margins, contacts and occlusal relationships for crowns, bridges, inlays and onlays. Modern scanners capture fine surface anatomy and three-dimensional occlusal data that help dental technicians and CAD software produce restorations with predictable fit. The ability to verify scans chairside and rescan any deficient areas improves the overall quality of the data sent to the laboratory.
Clinical studies and laboratory experience show that digital workflows can reduce remakes and adjustments when proper scanning protocols are followed. Digital files also make it easier to compare pre- and post-treatment models and to archive originals without taking up physical storage. When combined with established digital design and manufacturing processes, scans support reliable restorative outcomes.
Digital impressions accelerate turnaround by enabling electronic transfer of files to dental laboratories or in-office milling systems without the delays associated with shipping physical models. Laboratories that work digitally can receive, review and begin production immediately, which often shortens production times. When a practice has chairside CAD/CAM capabilities, the same digital scan can be used to design and mill a restoration during a single visit.
Same-day workflows require coordinated clinical and technical steps, including digital design, material selection and milling or sintering protocols. For appropriate cases, this integration reduces the number of appointments and the total treatment timeline. Clear digital communication between the clinician and technician helps ensure that same-day restorations meet clinical and esthetic objectives.
Digital impressions are designed to work with a variety of modern dental technologies, including CAD/CAM design software, chairside milling units and cone-beam computed tomography (CBCT). Scans can be merged with CBCT data to support implant planning and guided surgery, or combined with intraoral photography for shade selection and esthetic planning. Standard file formats such as STL and PLY allow interoperable workflows between clinical software and laboratory systems.
At ProSmiles OC, digital scanning is incorporated into restorative and implant workflows to improve coordination and planning. The combined data set enables clinicians and technicians to collaborate on margin design, occlusion and prosthetic emergence profiles before fabrication. This integrated approach supports more predictable treatment sequencing and clearer communication among team members.
Digital impressions are used for a wide range of restorative and cosmetic procedures, including single crowns, multiunit bridges, veneers, inlays and onlays. They are also routinely employed for implant abutment design, full-arch rehabilitations and removable prosthetics when appropriate. Orthodontic applications, such as clear aligner planning, often rely on digital models to produce sequential aligners that match the patient’s anatomy.
Because digital files can be shared instantly with specialists and laboratories, they facilitate coordinated care for complex cases that involve multiple providers. The technology supports both straightforward single-unit treatments and more complex multidisciplinary planning. Clinicians select digital or conventional techniques depending on case complexity, material considerations and laboratory capabilities.
Digital impression files are typically exported in standard formats and transmitted electronically to dental laboratories or partner services via secure file-transfer protocols. Practices and laboratories use encrypted networks or secure portals to maintain patient privacy during transfer. Files can also be stored locally on practice servers or in secure cloud repositories that comply with applicable privacy and security standards.
Archiving digital models eliminates the need for physical storage space and allows clinicians to retrieve original records for future comparison or restorative planning. Retained scans can be useful for monitoring wear, tracking treatment progress or coordinating care with specialists. Practices should follow local regulations and best practices for retention, access controls and patient data protection.
Yes, digital impressions may be merged with CBCT imaging to create a comprehensive 3D dataset for implant treatment planning and guided surgery. Combining surface scans with volumetric bone data enables prosthetically driven planning, which aligns planned implant positions with the final restoration. This integration supports accurate surgical guides and helps clinicians visualize soft‑tissue contours, emergence profiles and restorative space before surgery.
When the digital plan is transferred accurately to a surgical guide or navigation system, it can reduce intraoperative uncertainty and improve the predictability of implant placement. The same digital workflow can streamline the transition from surgery to provisional and final restorations by providing consistent reference data for laboratory and in‑office fabrication. Coordination between the surgical and restorative teams is essential to realize these benefits.
During a digital scan appointment you can expect a brief clinical exam followed by a fast, noninvasive scanning process that captures detailed images of your teeth and gums. The clinician will move a small handheld wand through your mouth while software builds a 3D model that appears on a monitor in real time. The process is comfortable for most patients, and the clinician can pause to address any sensitivity or concerns during the scan.
After the scan, the clinician will review the images with you and explain the next steps, whether the file will be sent to a dental laboratory or used for in‑office design and milling. If additional detail is needed, targeted rescans can be completed immediately to ensure accurate data. The overall experience is designed to be efficient, transparent and supportive of your restorative or cosmetic goals.
