Oval III Arch Shape - Slightly narrower arch but with longer legs.These nickel-free Beta Titanium alloy archwires were developed with the assistance of Dr Ravi Nanda. An excellent alternative over TMA archwires, the superb formability for placement of loops and bends reducing important chairside time. In addition, the flexibility makes it the perfect archwire for use during the mid-to-late stages of treatment.Doctors are moving to the CNA Beta III Nickel-Free over TMA because:CNA Archwire does not break as easily as TMA.The CNA Archwire has a smooth, high-polish finish which provides less friction.It is easier to form loops and bends with the CNA Archwire.Once intended shape is formed, the archwire maintains its integrity.Choose the CNA Beta III and you'll be able to move patients into a rectangular archwire more quickly to correct torque. Not to mention, you'll be able to work on root correction, and even over correction is possible by inserting bends. Pack of 10.
