In which decade were Essix clear retainers introduced to orthodontics?

• A. 2000s
• B. 1980s
• C. 1970s
• D. 1990s

Answer: (B)

Essix clear retainers came into orthodontics in the 1980s. They introduced a vacuum-formed clear plastic option that sits over the teeth with minimal bulk, offering a nearly invisible alternative to the bulkier Hawley retainers used previously. The technique relies on shaping a heated thermoplastic sheet over a dental model to produce a precise, comfortable appliance. Early descriptions and commercial use appeared in the late 1980s, which is why this decade is considered the introduction period. The 1970s predated their availability, while the 1990s onward saw their growth in popularity, but the initial introduction belongs to the 1980s.
