A Digital Path for Creating Accurate Immediate Dentures
Lori Trost, DMD
A terminal dentition treatment plan is often an overwhelming concept for patients when it comes to both the procedure and psychological acceptance. Former analog fabrication processes were cumbersome, complicated, and inefficient for the patient. The information transfer of impressions to models, then to wax rims and try-ins, to a final denture was laden with copy error. Resultantly, the actual production process was unpredictable due to approximating extraction sites, borders, and bony resorption. Each of these factors plays a critical role in the final delivery and patient comfort. With each procedural step, some accuracy is lost, which can translate to poor retention and discomfort. The digitizing of the immediate denture restorative workflow, beginning with the use of an iTero™ intraoral scanner (Align Technology, Inc., itero.com), has a significant impact on accuracy and predictability. This digital data improves lab communication while elevating patient outcomes and minimizing the number of appointments. As shown in the case presented, the final immediate denture design benefits from a digital design. Teeth can be virtually extracted. Occlusion can be digitally modified, exactly the opposite of a wax try-in where teeth can easily shift or move. Ultimately, the lab uses this organized data to create predictability in fit, function, and esthetics.

Immediate denture designs benefit from virtual extraction and accurate capture of vital landmarks. A monolithic denture can be leveraged as a try-in, allowing for any modifications before final delivery of the denture.
