Which material is commonly used for elastic separators?

Polyethylene
Rubber
Silicone
Plastic

The correct answer is: Rubber

The common use of rubber as a material for elastic separators stems from its unique properties that make it ideal for the tasks required in orthodontic procedures. Rubber separators are designed to create space between teeth by being inserted between them, allowing for the placement of orthodontic bands without damaging the tooth structure. Rubber is flexible yet resilient, which means it can exert sustained pressure to gradually separate teeth while conforming to the contours of the dental arch. This is essential as it helps in ensuring both comfort for the patient and effectiveness in the treatment process. Other materials like polyethylene, silicone, or plastic do not provide the same level of elasticity and adjustability needed for effective dental separation. While they may have their uses in dental applications, they lack the specific characteristics that make rubber the preferred choice for elastic separators in orthodontics.
