Abstract
The film holder for dental technique comprises a bite portion (4) and an approximately U-shaped film clip (5) including an oral (6) and a facial (7) plate. For a safe retention also of thin digital picture plates or of films and picture plates having an uneven topography without damaging their sensitive surfaces, the facial plate (7) is provided with means allowing to obtain a pressure distribution adapted to different thicknesses and/or topographies of films or digital picture plates.
