How is the sheet of rubber dam material stabilized after placement of the clamp in the mouth?

The stabilization of the rubber dam material after the clamp has been placed is achieved by ligating the tooth that is furthest away from the clamp. This technique is important because it helps maintain the integrity of the rubber dam during dental procedures, ensuring that the area remains dry and isolated from saliva and other oral fluids.

By ligating the furthest tooth, the rubber dam is effectively secured in place, allowing it to create a proper seal around the teeth that are being worked on. This prevents any leakage that could compromise the visibility and working conditions during procedures like restorative work or endodontics.

Other methods, such as tying a string to the clamp or using adhesive, may not provide the same level of security and stability as ligating the furthest tooth. Wrapping the rubber dam around neighboring teeth could also introduce complications or instability as it does not adequately hold the dam in the desired position.
