A digital intraoral scanner is a dental imaging device used to capture highly detailed digital impressions of a patient’s teeth, gums, and bite. Instead of using traditional dental impression materials, the scanner uses optical technology to create a three dimensional digital model of the oral structures. During scanning, a handheld wand is moved over the teeth and gums. The device captures thousands of images per second, which are processed by specialized software to generate a real time 3D representation of the patient’s dentition. The digital model can be viewed on a computer screen and stored as part of the patient’s dental record. Digital intraoral scanners are widely used in modern dentistry for procedures such as crowns, bridges, veneers, dental implants, orthodontic treatment, and diagnostic evaluations. The digital models produced by the scanner can be used for treatment planning and can be shared electronically with dental laboratories for fabrication of restorations or appliances. Because digital scanning eliminates the need for many traditional impression materials, the process can improve efficiency in the dental workflow and allow clinicians to evaluate and adjust scans immediately during the appointment.
UnderstandingÂ
Digital Intraoral Scanner
Clinical Significance
Digital intraoral scanning provides accurate digital representations of teeth and oral structures, supporting diagnosis, treatment planning, and fabrication of dental restorations.
Benefits to Treatment
Improved accuracy of dental impressions, faster digital workflows, enhanced treatment planning, and easier communication with dental laboratories.
How it Works
A handheld scanning device captures optical images of the teeth and gums as it moves across the mouth. Software combines the images to create a three dimensional digital model of the patient’s oral structures.
What it's Used For
To create digital impressions of the teeth and gums, support treatment planning, and assist in the fabrication of dental restorations and orthodontic appliances.
What Patients Can Expect
During the procedure, the dentist or dental assistant moves a small handheld scanner over the teeth and gums. The device captures images and displays a digital 3D model of the mouth on a nearby screen. The process is typically quick and noninvasive.
Downside
Digital scanners require specialized equipment and training, and scanning accuracy may be affected if areas of the mouth are difficult to access.
Frequently Asked Questions
What is a digital intraoral scanner used for?
Dentists use digital intraoral scanners to capture detailed digital impressions of teeth and gums for treatment planning and for creating dental restorations such as crowns, bridges, and orthodontic appliances.
Is digital scanning more comfortable than traditional impressions?
Many patients find digital scanning more comfortable because it usually does not require impression trays or impression materials placed in the mouth.
How long does an intraoral scan take?
Scanning the teeth typically takes only a few minutes, depending on the number of teeth and the type of procedure being performed.
Are digital scans as accurate as traditional impressions?
Digital intraoral scanners can produce highly detailed and accurate models of teeth and are widely used in modern dental treatment workflows.
Do digital intraoral scanners use radiation?
No. Intraoral scanners use optical imaging technology and do not involve radiation exposure.
