Ep. 632 - Why 3D Printing Is a Must-Have for Modern Dental Practices

Are you still struggling with messy impressions, delayed lab returns, and frustrated patients who need to wait days for retainers or night guards? The integration of 3D printing technology could revolutionize your practice workflow and patient experience.Dr. Julia Latham, a general dentist and partner in a five-doctor, 16-operatory practice in Stratford, Connecticut, brings extensive clinical expertise to this discussion. She earned her DDS from the University of Michigan School of Dentistry in 2011, where she received the William S. Kramer Award of Excellence and was inducted into the Omicron Kappa Upsilon Dental Honor Society. Dr. Latham has completed extensive postdoctoral training in orthodontics and maintains Invisalign Platinum provider status. After serving as a general dentist for the US Navy in Spain and practicing with Tidewater Dental Group in Virginia, she now focuses 50-60% of her practice on orthodontic and restorative care.This conversation explores how 3D printing technology transforms dental practice efficiency, patient satisfaction, and clinical predictability. Dr. Latham shares her experience implementing digital workflows that eliminate traditional impression-taking while maintaining high-quality outcomes. The discussion covers practical considerations for selecting equipment, managing staff training, and integrating new technology into busy multi-doctor practices.Episode Highlights:Digital workflow efficiency allows scanning patients with braces on, digitally removing brackets using free software like MeshMixer, and pre-fabricating retainers so bracket removal and retainer delivery occur in a single appointment. This eliminates patient wait times and reduces the risk of orthodontic relapse from delayed retainer pickup.DLP (Digital Light Processing) printers offer significant speed advantages over SLA (Stereolithography) systems because UV light cures entire layers simultaneously rather than point-by-point laser curing. Print times average 15-20 minutes for multiple models, making the technology suitable for high-volume practices.Post-printing workflow requires three essential steps: printing the appliance, washing in specialized alcohol solutions to remove uncured resin that would distort accuracy, and final UV curing. Support removal and minimal polishing complete the process, typically within hours rather than days.Temporary bridge fabrication uses eggshell-style printed shells created from pre-operative scans, which are then relined with traditional provisional materials during preparation appointments. This approach reduces chair time while maintaining proven material properties and clinical outcomes.Staff delegation allows assistants to handle STL file processing, printer operation, and routine appliance fabrication, while doctors maintain control over treatment planning and complex restoration design. Multiple assistants can be trained on digital file processing, though specialized printer operation requires dedicated staff members.Perfect for: General dentists and orthodontists considering 3D printing integration, practice managers evaluating digital workflow investments, and dental teams in multi-doctor practices seeking efficiency improvements.Discover how this technology eliminates impression-taking stress while creating new opportunities for same-day appliance delivery and enhanced patient satisfaction.
