Intraoral scanning, also known as 3D dental scanning, is a modern digital impression technique that is gradually replacing traditional methods. Using a handheld scanner, the dentist captures precise 3D data of the patient’s teeth, gums, and other oral structures. Unlike conventional impressions that rely on trays and impression materials, this digital process provides an accurate virtual model that can be viewed in real time on a computer screen. This allows for more precise diagnosis and treatment planning.
Traditional impressions require the dentist to fill a tray with impression material and place it in the patient’s mouth until it hardens. While effective, the process can be messy, time-consuming, and uncomfortable—sometimes even causing gagging.
In contrast, intraoral scanning is simple and far more comfortable. The dentist gently moves the scanner inside the mouth, and the process is usually completed within minutes. The resulting digital model is immediately available for use, eliminating the waiting time associated with impression materials or physical models.
A common question patients ask is whether a traditional impression is still necessary after a scan. In most cases, the answer is no.
The digital data captured is detailed enough to be sent directly to the dental lab for designing restorations or appliances, streamlining the entire workflow. This means fewer steps, faster turnaround, and less inconvenience for the patient.
That said, in certain special situations—such as highly complex restorations or unusual oral anatomy—a traditional impression may still be required. However, for the majority of cases, digital scanning is a more reliable and convenient option.
Higher Accuracy: Provides high-resolution 3D images for precise restorations and better treatment outcomes.
Patient Comfort: Eliminates the discomfort and gag reflex often associated with impression trays.
Time-Saving: Digital impressions are fast, and files can be sent instantly to the lab, avoiding shipping delays.
Easy Storage & Sharing: Digital models can be saved, retrieved, and shared effortlessly, which is useful for long-term patient care.
Eco-Friendly: Reduces the use of impression materials and disposable items, minimizing medical waste.
Intraoral scanning is transforming the way dental impressions are taken. While traditional impressions are still effective in certain cases, digital scanning offers greater accuracy, comfort, and efficiency for most patients. As more clinics adopt this technology, intraoral scanning is becoming the preferred choice for both dentists and patients who value precision and convenience.
