Assorted wooden wedges (WIZARD)

Separation of Teeth: Wooden wedges are used to create or maintain separation between adjacent teeth. This separation is essential for proper placement and adaptation of restorative materials.
Matrix System: They are commonly used in conjunction with a matrix band (a thin strip of metal or plastic) to help form a tight seal around the tooth and ensure that the restorative material is properly contained and shaped.
Contour Adjustment: The wedges help in adjusting and shaping the contour of the restoration by exerting pressure and ensuring that the composite or amalgam material is properly packed and contoured.
