Home / Appliances / Distalization / T-Rex T-Rex The T-Rex appliance is a Pendex modification with .032 stainless steel wires soldered to the first molar bands for greater molar expansion. Made to your Rx and shipped in 10 business days or faster.
Distalization T-Rex The T-Rex wires solder to the mesial-lingual of the first molar bands, so the appliance goes in as one unit. We pre-activate the springs, which makes insertion easier. You get the Pendex's expansion and distalization, with more expansion at the molars.
