What material is the Ostby dental dam frame typically made of?

The Ostby dental dam frame is typically made of plastic. This material is chosen because it offers a balance of durability, lightweight properties, and flexibility, making it easy to handle and comfortable for patients during dental procedures. Plastic frames can be easily cleaned and reused, aligning with infection control protocols commonly practiced in dentistry.

In contrast, metal frames, while sturdy, can be heavier and may not provide the same level of patient comfort. Rubber is not typically utilized for frames due to its tendency to stretch and not hold a shape as well as plastic. Wooden frames, while they may have been used historically in some applications, are not practical due to hygiene concerns and their inability to provide durability and longevity required in a dental setting. Therefore, plastic is the most suitable material for the Ostby dental dam frame in modern dental practice.
