One of the most important technological advances in modern dentistry, digital dental impressions are transforming the way oral structures are recorded, analyzed, and used for diagnosis and treatment planning. By replacing conventional impression materials with advanced intraoral scanning technology, dental professionals can obtain highly accurate, three-dimensional images of the teeth and surrounding tissues in a faster, cleaner, and significantly more comfortable way for patients.
Today, intraoral scanning is increasingly used – and widely regarded as the standard – in many private dental clinics, including PALMED partner clinics, focused on innovation, patient safety, and clinical excellence. This advanced technology enables dentists to achieve superior precision while significantly enhancing the overall patient experience, an objective strongly endorsed by international dental associations and supported by academic research.
We invite you to discover what a digital dental impression really is, when it is recommended, how it differs from the traditional method, and the key benefits it offers to patients.
What Is a Digital Dental Impression?
A digital dental impression is a virtual, three-dimensional reproduction of a patient’s teeth, gums, and bite, captured using an advanced intraoral scanner rather than traditional impression trays and materials. The scanner projects a structured light source or laser onto the oral tissues, capturing thousands of images per second, which specialized software instantly converts into a highly detailed 3D model.
Unlike conventional impressions that rely on alginate or silicone materials, digital oral scanning eliminates the physical discomfort, gag reflex, and inaccuracies associated with manual techniques. The resulting digital dental scan is displayed in real time on a computer screen, allowing both the dentist and patient to visualize the oral anatomy with exceptional clarity.
From a technological standpoint, digital impressions rely on optical scanning principles, high-resolution cameras, and artificial intelligence-driven software algorithms. These systems ensure precise capture of tooth morphology, interproximal contacts, occlusal relationships, and gingival contours – key elements for accurate restorative and orthodontic outcomes.
When Are Digital Dental Impressions Recommended?
Digital dental impressions are recommended in a wide range of dental procedures, particularly when precision, predictability, and efficiency are essential. Their versatility makes them suitable for both routine and complex treatments, across multiple dental specialties.
For Dental Crowns and Bridges
One of the most common indications for a digital dental impression is the fabrication of crowns and bridges. In restorative dentistry, even minimal inaccuracies can compromise marginal fit, occlusion, and long-term durability.
With intraoral scanning, dentists can capture the prepared tooth and adjacent structures with micron-level accuracy. The digital model is then transmitted directly to the dental laboratory, reducing human error and minimizing the need for remakes or chairside adjustments. Studies confirm superior marginal adaptation when digital impressions are used for fixed prosthodontics.
For Orthodontic Aligners (Invisalign)
Clear aligner therapy, including systems like Invisalign, relies almost entirely on digital dental scanning. A precise 3D model of the dentition is essential for planning tooth movement stages and predicting treatment outcomes.
Through digital oral scanning, orthodontists can simulate the entire treatment process before therapy even begins. This allows patients to visualize expected results, improves compliance, and significantly shortens treatment planning time compared to traditional plaster models.
For Dental Implants
Implant dentistry demands exceptional accuracy, particularly in designing implant-supported restorations. Digital dental impressions play a critical role in the prosthetic phase, capturing highly precise 3D data of the implant site, surrounding teeth, and soft tissues. This allows dental laboratories to design crowns, bridges, or other restorations with optimal fit, angulation, and long-term stability.
Academic publications emphasize that digital workflows in implantology contribute to higher success rates and reduced post-operative complications.
Benefits of Digital Impressions in Dentistry
The transition to digital impressions has brought substantial benefits for both patients and dental professionals, fundamentally improving the quality and efficiency of dental care.
First and foremost, precision is significantly enhanced. Digital scanners capture details that are difficult or impossible to reproduce with traditional materials, such as subtle occlusal relationships and undercuts. This level of accuracy directly translates into better-fitting restorations and improved clinical outcomes.
Speed is another major advantage. A digital dental scan can be completed in minutes, with instant visualization and immediate data transfer to the dental laboratory. This reduces treatment time, shortens waiting periods, and allows faster delivery of prosthetic solutions.
Patient comfort is equally important. Unlike traditional impressions, which often cause nausea, gagging, or anxiety, intraoral scanning is non-invasive and well tolerated even by patients with strong gag reflexes or dental phobia.
How Is Digital Dental Scanning Performed?
Let us take you through the non-invasive, reliable, and comfortable process of digital dental scanning. Understanding each step helps patients see how this technology delivers precision, efficiency, and ease of use, making modern dental care simpler and more enjoyable.
The Scanning Process Step-by-Step
The procedure begins with a brief clinical examination to ensure that teeth and soft tissues are clean and dry. The dentist then introduces the intraoral scanner – which is a small, handheld device – into the patient’s mouth.
As the scanner moves over the teeth and gums, it captures thousands of images per second. These images are instantly processed and merged into a real-time 3D model displayed on a monitor. If any areas are missing or unclear, the dentist can rescan specific regions immediately, ensuring a complete and accurate digital dental impression.
Once finalized, the digital file is stored securely and can be shared electronically with dental laboratories or used for patient education and treatment planning.
Technology Used
Leading digital impression systems include 3Shape TRIOS and iTero, both recognized internationally for their reliability, accuracy, and ease of use. These platforms are widely adopted by private dental clinics that prioritize innovation and evidence-based practice.
According to studies, these technologies significantly reduce impression errors and improve clinical efficiency compared to analog methods.
Difference Between Digital and Traditional Dental Impressions
The difference between digital and traditional impressions is substantial, both in terms of patient experience and clinical outcomes.
Traditional impressions require bulky trays filled with viscous materials that must remain in the mouth for several minutes. Many patients report discomfort, gag reflex, or even vomiting sensations during the procedure. Additionally, material distortion, air bubbles, and improper setting can compromise accuracy.
In contrast, a digital dental impression eliminates these issues entirely. There is no physical material, no unpleasant taste, and no pressure on oral tissues. Accuracy is consistently higher, and results are available immediately, without the need for retakes or repeated appointments.
Is Intraoral Scanning Painful?
A common concern among patients is whether intraoral scanning causes pain. The answer is clear: digital dental scanning is non-painful and non-invasive.
The scanner does not apply pressure, generate heat, or cause tissue irritation. Most patients describe the experience as neutral or even pleasant compared to traditional methods. This makes digital oral scanning particularly suitable for children, elderly patients, and individuals with heightened sensitivity or anxiety.
