Digital impressions in Dentistry represent cutting-edge technology. It allows dentists to create a virtual, computer-generated replica of the hard and soft tissues in the mouth using lasers and other optical scanning devices. These significantly increase efficiency, productivity and accuracy, and make it possible for dentists to e-mail the virtual impression to the laboratory, rather than send a traditional impression or stone model via regular mail.Conventional Vs Digital Impression 
Digital Impressions and Dental Scanners
The images can be captured using lasers or digital scanning.Laser scanning uses concentrated light that is safe and highly precise. It captures all of the details of the teeth and gums while eliminating the patient’s need to hold unpleasant, distasteful material in his or her mouth.Digital optical scanners also are safe and highly accurate, but require teeth to be powder-coated with a special spray before scanning to ensure all parts of the impression are recorded properly.A digital scan enables dentists to see the positive image and magnify and evaluate it carefully. Errors can be corrected immediately before submitting the impression to the laboratory.Once the digital impression has been completed, the clinician can select from a series of diagnostic tools to evaluate the preparation and complete the impression.

Digital Impression for an Orthodontic CaseOrthodontists use digital impressions to create 3D models of the position of the teeth for proper treatment planning and correct placement of the treatment appliances. An orthodontist can do a dedicated orthodontic planning software to determine the most accurate and functional way to place braces, clear aligners, or other retainers, in order to get the desired outcome.
Digital Impressions for Implant ProsthesisCAD/CAM technology made it possible to fabricate implant-supported restorations through a digital workflow. Digital impressions transfer the intra-oral situation to a virtual model and represent the first step of the digital workflow.The accuracy of this procedure may determine the success of the treatment, since it is a crucial step to transfer the implant position correctly. If it is performed poorly, it can lead to a misfit of the final prosthesis, which may result at long last in mechanical and biological complications.
ADVANTAGES - Less chair time.
- Patient and dental team will have more comfortable and stress-free experience.
- Using inserting impression materials and trays with in patient’s mouth, digitized impressions by IOS reduces temporary pain.
- The screening of the participant’s hard and soft tissues reduces chair side duration. Steps that take time, such as filling the casts, are omitted.
- Improve the impression quality for better fitting restorations.
- Reduce possibility of impression-taking errors.
- There’s no need to buy spoons or imprint materials, and there’s no need to store them.
- Air bubbles are not a concern with this procedure.
- The elimination of the “unclean” cabinet, as well as patient distress.
- The interaction between the physician and the patient has increased since the introduction of IOS, and the individual is much more integrated in the process and also has a significantly better treatment efficacy.
Conclusion By eliminating the common challenges associated with traditional impressions, intraoral digital scanning is poised to become the standard procedure in most dental offices in the coming years. Digital impressions have been shown to reduce remakes and returns while enhancing overall efficiency. Patients also benefit from a more comfortable and positive experience. Additionally, the use of digital impressions leads to more consistent laboratory results, minimizing the need for adjustments and reducing chair time during crown or restoration placement.
