Two teeth in same arch are in contact,their curvatures adjacent to the contact area form spillway spaces. Embrasures are two types Labial/Buccal and lingual embrasures. The space that widen out from the area of contact labially or Buccal or lingually.These embrasures are continuous with the interproximal saves between the teeth. Incisal or occlusal embrasures are the spaces which are bounded by the marginal ridges as they join the cusps and incisal ridges. Function mainly is to Provide a spillway for food during mastication which prevents food from being forced through the contact area. Thus Makes teeth more self cleansing.
