Orthodontic spacer. Orthodontic separators (commonly known as spacers) are rubber bands or metal appliances used in orthodontics. Spacers are placed between the molars at the second orthodontic appointment, before molar bands are applied. Spacers are either circular rubber bands about a centimeter in diameter placed between top and bottom molars; there may be 1-12 spacers applied or small metal spring clips (spring separators) that push the molars apart.
