Abstract
Abstract An elasticized stabilizer for temporarily immobilizing a tooth-to-tooth retainer wire as commonly applied in orthodontia. The stabilizer comprises an elongated filament with modifications or enlargements on each end. When the filament is stretched and placed between two adjacent teeth, the retainer wire is urged toward the teeth and held in position during installation.
