The word of our head doctor

Joseph Massad, DDS


“I am pleased to bring my revolutionary impression trays back to the market and announce my partnership with Ransom Randolph. My trays are a perfect fit with RR’s existing dental line. As one of the oldest dental suppliers and a global leader in dental stones and model making, teaming up with R&R just made sense. We coupled the Massad tray system, including my new Overdenture tray, with RR’s FiberStone™ resin die stone to create models for a variety of cases, including implant analogs, edentulous models, and small teeth fragment models. Our results have been excellent, with exceptional strength, detail, and scanning ability. I highly recommend FiberStone resin die stone! Plus, finding my trays is now easier than ever with RR’s distribution partners, global logistics, and e-commerce options.”
