Full overlay. 

Full overlay cabinetry covers the entire face frame in framed construction and hides the cabinet box in frameless designs. This case front style shows a continuous façade of door and drawer faces, resulting in a seamless appearance. With so many door styles available, full overlay cabinetry may now be considered modern or traditional in appearance based on the chosen door.

Partial overlay. 

In partial overlay construction, a portion of the cabinet box or face frame is left partially exposed. The uncovered portion of the box is known as a reveal. In face-framed construction, a half-inch overlay door and drawer front leaves two inches of the cabinet frame exposed between drawers and door fronts. A quarter-inch reveal in face framed construction leaves slightly less of the face frame visible.
