A practical, convenient, and accurate method of measuring the physiologic rest position and occlusal vertical dimension by using a vertical dimension recorder (VDR) was described by Makzoume.1 The VDR consists of a plastic 20-cm ruler suspended from a rectangular plate and rod attached to the forehead and a square plate with a needle pointer attached to the chin. The plates are attached to the forehead and chin with double-sided foam adhesive tape. In individuals with a beard, it is impractical to attach the needle pointer to the square plate with adhesive tape.
