This fast-paced, practical workshop is for dentists and teams who want a simple, reliable path to in-house manufacture. We’ll cover MSLA/DLP printing and chairside milling for splints, mouthguards, whitening trays, onlays/inlays, and single-unit crowns/bridges (provisional and definitive, material-dependent). You’ll learn when to print vs mill, how to keep costs down, and how to get consistent, patient-ready results without fuss.
Across the day we’ll run through scan → design → manufacture → finish using straightforward clinical workflows. You’ll get hands-on with file prep, printer settings, CAM/nesting, burs and toolpaths, post-processing, crystallisation/sintering where required, and chairside finishing/polishing. Whether you’re just getting started or streamlining what you already do, you’ll leave confident to produce everyday appliances and restorations in-house, on time and on budget.
What You Will Learn
MSLA vs DLP: strengths, limits, and clinical use cases
When to print vs mill: a simple decision guide (fit, finish, strength, turnaround, cost)
Chairside applications: occlusal splints, sports mouthguards, whitening trays, onlays/inlays, and crowns/bridges (provisional and material-approved definitive options)
Printing workflow: file preparation, supports, orientation, printer setup
Post-processing: wash, cure, and finishing best practice for biocompatible resins
Materials for printing: indication-specific, mechanical properties, and record-keeping
Milling workflow: block/disc selection (PMMA, hybrid composite, glass-ceramic, zirconia), CAM basics, nesting, sprues, and bur sets
Furnace steps: crystallisation/speed-sintering essentials (time/temperature are system-specific), stain-and-glaze, and chairside polish
Cementation & bonding basics: prep design, isolation, and surface treatment by material
Hybrid workflows: print the provisional today, mill the definitive when appropriate
Troubleshooting: failed prints, warping, chipping, margin fractures, fit issues
Maintenance & calibration: daily/weekly checks for printers, mills, furnaces, and handpieces
Time & cost: simple chairside calculators to budget minutes and dollars per case
