As you secure the blue bib around your patient’s neck, you see their jaw clench in anticipation of the gooey, cakey dental putty that’s soon to encase their teeth. They gag, attempt to breathe through their nose, and gag again before you remove a perfect replica of their chompers.
Dental impressions allow dentists to produce essential dental restorations for patients, which include crowns, bridges, braces, retainers, dentures, and dental implants. While traditional, putty-like dental impressions have been used since the 1800s, a technical type of dental impression is now readily available: digital impressions.
In this guide, we’ll discuss the differences between digital impressions vs traditional impressions, and how dental practitioners can implement digital impression scanners into their practices.
Traditional impressions use putty-like materials, such as alginates or polyether vinyl silicones, to create negative molds of a patient’s teeth.
To obtain one of these molds, dentists must place the putty into a U-shaped tray and insert it into the patient’s mouth. Once the material hardens to the right consistency, dentists can carefully remove the impression and mail the mold to the lab.
Once at the lab, the dental impression can be used to make any of the following:
- Dental implants
- Implant-supported dentures
- Teeth whitening trays
- Night guards
- Sports mouth guards
The Traditional Dental Impression Process
When creating a traditional impression, a dental practitioner prepares the putty-like impression material by mixing together the base and catalyst. The putty is then portioned into a plastic or metal tray that’s properly sized for the patient’s mouth. From there, dentists adhere to the following steps:
- Step 1 – Place the tray into the patient’s mouth and push it against their teeth
- Step 2 – Wait a few minutes for the material to harden
- Step 3 – Repeat the process with the other set of teeth
- Step 4 – Remove the tray and allow the patient to clean any putty residue out of their mouth
- Step 5 – Send the impression to a dental lab
If this process goes smoothly, it can take around 15 minutes.
Unfortunately, traditional impressions don’t always go as planned. Dental practitioners will often have to redo the process if the mold gets damaged as it’s removed from the patient’s mouth.
Another downside of traditional impressions is that they can be very uncomfortable for the patient—as the unpleasant-tasting goop flows outside of the trays, patients may start to gag.
The Digital Dental Impression Process
Using the intraoral scanner, dentists can scan around each tooth. The digital software then stitches the images together to create an accurate impression model of the patient’s mouth.
That said, the digital impression scanner process is significantly more streamlined than the traditional method. In turn, it boasts many benefits, including:
- Faster impression appointments – Since the digital scanning process is so fast, it can speed up your patients’ appointment times and open up your schedule to take on more business.
- Quicker restoration turnaround times – Digital impression scanner images get sent to the dental lab electronically. As a result, you don’t have to go through the hassle of shipping physical impressions in the mail and paying the associated shipping costs. Your patients can also enjoy a reduced turnaround time in receiving their restorations.
- Enhanced patient experience – No one enjoys gagging on goop during traditional impressions. As a no-gag alternative to dental impressions, digital impressions are much more comfortable for patients. What’s more, many patients are impressed by the technology.
- Improved accuracy – Intraoral scanners capture every small intricacy of the teeth, leading to detailed 3D models. Due to their high level of accuracy, digital impressions lead to better restoration results and significantly fewer redos than traditional impressions.
- Simplified expenses – When you take digital impressions, you no longer need to constantly restock your office with costly dental trays, putty materials, and mixing bowls.
Partner With Dandy and Enjoy the Benefits of Digital Impressions
While traditional methods of creating dental impressions involve a putty-like substance that’s used to make a mold of a patient’s mouth, digital impressions use advanced dental technology to create a digital scan of the teeth, gums, and bite.
Digital impression technology eliminates the need for unpleasant molds, provides a highly accurate rendering of a patient’s mouth, and can improve the patient’s experience.
