Overcoming the contact points in modern coffer dam technique
The isolation of the operating area with disposable covers is standard practice in general medicine all over the world and is an example to be followed by isolation in modern dentistry. This article describes new techniques of overcoming the contact points and contrasts the OptraDam Plus isolation concept to the conventional coffer dam. Experience in the practice proves that overcoming the contact points is the most difficult challenge in the application of a coffer dam.
Due to the different anatomies, accessibility and separability of the teeth the isolation of front and side teeth is practiced with different techniques.
Overcoming the contact point at the easily accessible anterior teeth is achieved manually by hyperextension, overcoming of the strong contact points in the side teeth area with the “double wedge” technique. Both ways of isolation can be conducted by a single person. They are more suited to the new isolation concept presented, as the covering coating has the adverse apical traction direction as opposed to the conventional coffer dam.
