chewies: Definition, Uses, and Clinical Overview
chewies are small, compressible chewing aids used in clear aligner orthodontics and sometimes with retainers. They are typically made from a resilient elastomer (often silicone-like) that patients bite on to help seat an appliance. They are commonly used with clear aligner systems to improve how closely an aligner fits against teeth. They may also be called “aligner seaters,” depending on the clinician and manufacturer.
