The digital scan is then instantly available for review and can be sent to dental laboratories or specialists electronically. This rapid turnaround time accelerates the entire treatment process, reducing chair time for patients and enabling quicker restorations.

  • Enhanced Communication

Digital impressions have introduced a new level of convenience and efficiency in communication between dental professionals, laboratories, and specialists. Once a digital impression is captured, it can be easily shared electronically with the dental laboratory or specialists involved in the treatment process. This seamless exchange of information fosters improved collaboration and treatment planning.

For example, a digital impression of a patient’s teeth can be instantly shared with an orthodontist for treatment planning, or with a dental laboratory for the fabrication of a crown or bridge. This real-time sharing of information enhances the overall quality of care and ensures that all stakeholders are on the same page.

  • Equipment Costs and Learning Curve

While digital impressions offer numerous advantages, there are also some challenges associated with their adoption.

Dental professionals need to become proficient in operating digital scanners, capturing accurate scans, and interpreting the digital models they produce. Training and education are essential to ensure that dental professionals can harness the full potential of digital impression technology.

Traditional Impressions: Benefits and Limitations

  • Proven Track Record

Traditional impressions have a long history in dentistry and have proven their reliability over time. Dental professionals have been using traditional impression techniques for decades to create accurate models of patients’ oral anatomy. This track record of success has established traditional impressions as a tried-and-true method in dental practice.

Traditional impressions involve using impression materials, such as alginate or silicone, which are placed in a tray and inserted into the patient’s mouth. As the material sets, it captures the shape of the teeth and tissues, providing a mold that can be used to fabricate restorations or orthodontic appliances.

  • Cost-Effectiveness

One of the significant advantages of traditional impressions is their cost-effectiveness, particularly in terms of initial investment. Traditional impression materials and trays are more affordable compared to the digital scanners and technology required for digital impressions. This cost-effectiveness can be appealing for dental practices that are working within budget constraints.

  • Familiarity and Training

Dental professionals are familiar with traditional impression techniques due to their historical prevalence. Dentists, dental assistants, and dental hygienists have received training in traditional impression methods as part of their education and training. This familiarity can lead to a smoother workflow and quicker impression capture, as dental professionals are well-versed in the process.

  • Versatility in Materials

Traditional impressions offer a wide range of impression materials to choose from, catering to different patient needs and preferences. These materials come in various viscosities, setting times, and consistencies, allowing dental professionals to select the most appropriate material for each specific case.

For instance, dental professionals can choose a more viscous material for situations where the patient has a deep bite or limited mouth opening, ensuring that the material captures all necessary details accurately. This versatility enables dental professionals to tailor their approach to each patient’s unique oral characteristics.

  • Discomfort and Mess

One limitation of traditional impressions is the potential discomfort and inconvenience experienced by patients. The process involves placing impression trays filled with impression material into the patient’s mouth, which can lead to a feeling of pressure and discomfort. Patients may also experience a gag reflex triggered by the presence of the tray and material in their mouths.

Additionally, some patients find the texture and taste of impression materials unpleasant. These materials can leave a temporary residue on the teeth and oral tissues, which can be messy and uncomfortable for patients.
