Eliminating the Guesswork: The Complete Digital Workflow in Implant Dentistry

In the past, clinicians relied almost exclusively on their subjective and sometimes incorrect clinical evaluation and judgment. Limited knowledge and understanding of facial and dental esthetics and the inaccuracies and distortions of analogue procedures, such as impression making, facebow transfer, interocclusal record taking, and use of analogue articulators, often compromised clinical outcomes, especially in implant dentistry, which requires an interdisciplinary approach. In contrast, digital tools and software can greatly improve visualization, evaluation, diagnosis, and decision making as well as interdisciplinary treatment planning and execution.

The complete digital workflow begins with the patient digitalization, obtained by the scanning of hard and soft tissues. This is facilitated through the use of intraoral scanners, cone-beam computed tomography, and additional digital tools, such as digital smile design software, virtual articulators, and jaw tracking devices. An advantage of this approach is that many of the diagnostic and planning steps can be carried out on the computer, even without the patient being present, saving valuable chairtime. More recently, several digital diagnostic and treatment planning tools have been powered by artificial intelligence to speed up the process and provide improved accuracy and calibration, most notably in the area of automated radiographic evaluation. The obtained files can be immediately stored in a dental cloud platform and shared with the professional team. An interdisciplinary treatment plan is designed through asynchronous communication with input from all team members, including the restorative dentist, surgeon, and technician. Other specialties, such as periodontics, orthodontics, or endodontics for example, can be easily consulted as needed.

Next, the planned treatment is simulated in a 3D software. These treatment options along with the desired outcome are presented to the patient on the computer and, if possible, with an intraoral mock-up. These simulations not only help the clinician make better decisions but also serve as a tool for patient education, motivation, and case acceptance.

The process is then completed with so-called guided dentistry, which implies that surgical guides, appliances, and restorations can be printed or milled to transfer the digital plan to the patient's mouth. Especially in implant dentistry, surgical guides have become indispensable for optimal clinical care, ensuring precise implant placement for all types of cases, from single-unit restorations to full-mouth reconstructions. Proper implant position is critical for any type of prosthetic reconstruction and its esthetic and functional long-term success.

In the dental laboratory, the design, material selection, and fabrication of the definitive restoration have long been aided by digital technologies and are constantly undergoing improvements. It's now up to clinicians to embrace a comprehensive digital approach, not just to be "cutting-edge," but to provide patients with more precise, predictable, and, ultimately, better care.
