Abstract
Abstract A cushioning bite plate adapter for use with a dental x-ray film holder comprises an elastically compressible member which has an attachment surface for engaging a surface of a bite plate of the film holder. An adhesive layer is disposed on the attachment surface of the elastically compressible member. A protective peel-off sheet is disposed over the adhesive layer. To use, the protective peel-off sheet is removed and the adhesive layer on the attachment surface is pressed into contact with the bite plate surface. The adhesive layer maintains the elastically compressible member in contact with the bite plate surface. Following use, the adapter is separated from the bite plate surface and thrown away.
