NDX Muth & Mumma

Behind the nondescript glass of a corporate plaza in northern Harrisburg sits NDX Muth & Mumma, a dental laboratory quietly turning impressions into crowns and models into bridges every week. Crowns, bridges, dentures, cast partials, and surgical guides roll off the benches Monday through Friday, dispatched to practices across central Pennsylvania before the weekend. The shop handles full-contour zirconia as routinely as layered porcelain, and its digital team can output an STL file from a clinician’s intraoral scan in hours, not days.

You’ll find the lab at 6360 Flank Dr #500 in the shadow of Blue Ridge Summit, a stone’s throw from the Susquehanna. Interstate ramps and local traffic funnel through the same stretch of retail parks, so drop-ins are rare; referrals arrive on FedEx Labels and digital work orders instead. The entrance sits on the second floor, above a bridal boutique and a tax office, tucked beside the elevator lobby.

Call (717) 540-5626 only if you need a quote on a wax‑up or a CAD‑CAM revision before noon—that’s the window they update pricing on zirconia frameworks. Same-day turnarounds are priced at a premium after 1 p.m., so plan accordingly if you’re up against a crown-and-bridge case that needs seating before Monday.

When the GPS stalls on Flank Drive, plug the address into the map before you leave the parking lot: directions will steer you to the visitor lot and straight to the elevator. The plaza’s north end stays quiet after 4:30, so the lab’s loading bay rarely sees foot traffic from curious dentists or dental assistants.
