length of the lesion, and are fastened to the wall by two or 
more\screws on either side of the crack. It is an advan-

fitting \t hot. In a complicated crack the plate serves the 
further \useful purpose of holding in position antiseptic 
pledgets, and so keeping the lesion free from dirt and grit.
