3D Digital impression: How is it different from traditional impression?

3d digital impression is the latest technology in capturing a replica of the mouth which uses a wand-like tool connected to a computer and advanced software. A dentist can create a virtual model of the hard and soft tissues in the mouth. These replicas are more accurate than a mold and can be used for a variety of needs, after taking a scan of the mouth. Then, the dentist immediately sends the digital impression to a lab where crowns, dentures, retainers and bridges can be made quickly and accurately.

Types of digital impression

There are two types of digital impressions, which are currently being used by dentists. One was image based, capturing a series of digital photographs while the other captured a digital video. In image based, images are captured in the form of digital photographs and then digital
photographs are then provided to dental laboratories.

In other types of dental impressions capture the images in the form of a digital video. Dental laboratories have a complete video that helps them in restoring the smile of the patient. The images are captured with the help of digital scanning or lasers and the laser scanning concentrate light which is accurate and safe.

Digital impression cost

Digital impression cost is around $21,000 to $24,000 for equipment and training. These devices provide dental practices with numerous cost savings and drastically reduce the need for traditional impression materials which cost approx. $30 per impression.

Digital impression and traditional impression

Traditional impressions involve multiple materials and more steps. This is a highly delicate and skilled process which is easier to introduce errors throughout any of the numerous steps involved, either from the human element or material defects.

Digital impression devices eliminate much of the labor and guesswork associated with traditional impressions. It reduces or eliminates error and increases time saving both during the impression appointment and delivery of the restorations. This method is much faster and more precise which creates a positive impression.

Benefits of 3D digital impression

• Improved impression quality for better-fitting restoration
• More comfortable, less anxious experience for both patients and the dental team.
• Less chair time significantly for patients.
• Reduce possibility of impression-taking errors and elimination of materials inaccuracies for fewer restoration mistakes.
• Patient feel more included in the treatment as they can see their impressions on the screen
• It is an eco-friendly procedure as plastic trays and impression materials are no longer required.
• There is a higher probability of error in the process and the detailed images and video have a smaller margin in error.
• It can be stored electronically indefinitely which saves spaces, contributes to efficient record keeping and supports a paper-free environment.
• This entire process of taking a scan of the teeth, its opposing teeth and bites are done in a few minutes.
• There is no need for distasteful impression materials that cause some patients to gag.
