Accept no others! The Columbia Model 860 PVR is the first typodont made for dental education over 50 years ago. It remains the most popular typodont used by US and Canadian dental schools because of it’s quality and durability. Made of strong materials, flexible gingiva with replaceable teeth. Dental schools will not accept knock-off typodonts, so when you purchase this typodont, you are practicing with the same typodont you’ll be using on the bench examinations. Replacement teeth available. This is a refurbished model and in a good condition for practicing bench exam.
