- - - - Your upper jaw is directly under your nasal sinuses. Implants to replace your top teeth can potentially penetrate into the sinus, leading to discomfort or possible infection.
- - - - Class I, II, V, IV
- - - - Lower value of elastic modulus, improved values of springback (YS/E) and result in increase their working range for tooth movement.
      - Possessing true weldability during orthodontic treatment
      - Potential for delivering lower biomechanical forces
    - - Cannot endure orthodontic heat treatment becasue it can cause yields a nearly all-β microstructure
      - Reactivity of titanium cause archwires susceptible to fracture during clinical manipulation
    - - Beta-titanium wire has lower force magnitudes, a lower elastic modulus, higher springback (maximum elastic deflection), a lower yield strength, and good ductility, weldability, and corrosion resistance
  - - - Biocompatible
      - Higher the chromium content, better corrosion resistance of alloy
      - Superior mechanical properties
      - Can be electrolytically polished
      - Available in four tempers (levels of resilience) that are color-coded by the manufacturer: blue (soft), yellow (ductile), green (semi-resilient), and red (resilient)
    - - Has the tendency to harden near soldered or spot-welded joints
      - Fast work-hardening than other alloys
      - Can cause an adverse reactions in patients that allergic to nickel
    - - Can easily be manipulated into the desired shape and heat-treated with considerable increases in strength and resilience.
      - Also known as Elgiloy
