Ep. 629 - Printed Efficiency: Revolutionizing Your Practice with a 3D Printer

Is your dental practice still using traditional impression materials and lab workflows when you could be printing models, guards, and restorations right in your office? The shift to in-office 3D printing is revolutionizing how dental practices deliver care, offering unprecedented efficiency and control over the treatment timeline.

Dr. Susan McMahon brings exceptional credentials to this discussion. A graduate of the University of Pittsburgh School of Dental Medicine, she maintains one of Western Pennsylvania's largest cosmetic dental practices and holds accreditation from the American Academy of Cosmetic Dentistry - an achievement shared by only 350 dentists worldwide. She is a Fellow in the International Academy of Dental-Facial Esthetics, serves as Director of New Product Evaluation for Catapult Education, and was recently inducted into the prestigious American Society for Dental Aesthetics. A past clinical instructor in Prosthodontics and Operative Dentistry at the University of Pittsburgh, Dr. McMahon has been honored as a Top Cosmetic Dentist five times and is a seven-time award winner in the AACD's Annual Smile Gallery.

This episode explores how 3D printing has become an indispensable tool in Dr. McMahon's practice workflow. She discusses the practical applications currently being used in dental offices, from basic models to complex restorations, and explains why 3D printing might actually be a better entry point into digital dentistry than milling for many practices. The conversation covers implementation strategies, material selection, and the cost-effectiveness of bringing these capabilities in-house.

Episode Highlights:

• Modern 3D printers range from $7,000 to $12,000 and offer exceptional accuracy with small footprints, making the technology accessible for most practices. The ability to print multiple units simultaneously significantly increases production efficiency compared to single-unit milling workflows.
• In-office clear aligner printing represents a major disruptive technology that will dramatically reduce treatment costs and challenge the current market dominated by large aligner companies. Software advances now allow direct progression from intraoral scans to printed aligners with AI-assisted treatment planning.
• Ceramic composite materials for printed inlay-onlays provide excellent clinical results, though zirconia printing at mill-quality strength remains several years away from clinical viability. Current printed restorations work particularly well for bicuspid crowns and provisional applications.
• Implementation requires identifying a tech-savvy team member and establishing proper material storage systems, as each application requires specific material trays. The workflow involves scanning, STL file transfer, design software interaction, and post-processing through wash and cure stations.
• Surgical guide printing allows same-day consultation to two-day surgery timelines, providing unprecedented practice control over implant workflows. This eliminates the traditional 1-2 week wait times associated with laboratory-fabricated guides while maintaining precision.

Perfect for: General dentists and specialists considering digital workflow integration, practice owners evaluating efficiency improvements, and dental teams ready to implement advanced manufacturing technologies.
