Step-By-Step Digital 3D Workflow

February 17, 2023

Over the years, Digital Dentistry has become a normal—even expected—feature of oral health care and treatment. Technological innovations such as 3D scanners and printers are now considered essential in clinics nationwide.

With all these wonders proliferating the dental field, is now the best time for practitioners who have yet to switch to digital dentistry to familiarize themselves with the process? Increasingly, it looks like the answer is “Yes.”

What Is Digital Dentistry?

Digital Dentistry refers to any dental technology or device that uses digital or computer-based components to replace traditional mechanical or electrical methods.

New tools, such as lasers for surgical procedures and the removal of decay, allow for safer techniques in tooth and oral tissue removal. Meanwhile, improvements in other digital devices like those of cone-beam computed tomography machines, and 3D technology have made it possible for dental offices to afford systems that provide patients with computer-aided implants.

The Dental Workflow Process Using 3D Technology

To gain a better understanding of digital dentistry, below is a brief step-by-step guide of a dental workflow using 3D technology.

Step 1: Initial examination and intraoral scanning

The process begins with capturing a patient’s digital impression. This is done using an intraoral scanner that produces digital images of a patient’s dentition and bite relationship.

In the past, dental exams frequently required X-rays and physical molds. On the other hand, digital dentistry begins with an intraoral scanner taking a digital picture of the patient’s mouth. These scanners produce a very accurate three-dimensional (3D) model of the patient’s teeth and gums, providing a thorough view without the discomfort associated with taking traditional impressions.

Step 2: Diagnostic analysis and treatment planning

Once the digital impressions are captured, the dentist can then show the patient the results of the scan on-screen and begin discussing treatment plans.

Also, after the dentist has these digital images in hand, sophisticated software helps analyze the patient’s oral condition accurately. Precise measurements and analysis of tooth alignment, bite, and other important details are made possible by these digital models. After that, dentists can design a customized treatment plan for any procedure—like dental implants and orthodontic adjustments, to name a few.

Step 3: Virtual simulation and design

Once the initial treatment plan has been established, there are numerous options for taking the plan from concept to visualized reality.

Digital dentistry enables dentists to simulate the expected outcome of treatments. Using computer-aided design (CAD) software, they can manipulate the 3D models to virtually plan and design restorations or modifications. For instance, in the case of a dental crown, the dentist can design its shape, size, and fit before actually creating it.

Step 4: 3D printing and fabrication of dental models
Digital files gathered earlier are converted into a physical dental model for appliance manufacturing and in turn used for oral treatment.

The digital data is sent to a milling machine or a 3D printer after the design is finalized. These technologies use ceramics or resins to create dental restorations such as crowns, bridges, and aligners. The restorations will precisely match the intended design thanks to 3D printing’s precision.

Step 5: Post-treatment assessment

Digital dentistry also allows for easier post-treatment analysis that can quickly encompass a larger scope of analysis.

Dentists can compare before-and-after 3D models to assess the effectiveness of the treatment. This step helps in ensuring the success of the procedure and enables dentists to make any necessary adjustments. The ease and speed of in-house imaging and fabrications means that patients get the adjustments in treatment they need at the speed and level of convenience they are coming to expect.

Easy to Use, Greater Payoff

In the past, 3D printing was always outsourced to dental laboratories. But with the recent developments in 3D technology, dental offices are now allowed to manufacture accessories on their own and drastically cut waiting time on manufacturing dental appliances.

3D printing technology’s success lies in its ease of use that leads to larger returns in investment and quality patient care.
