Abstract
The device for measuring the thickness of the mucous membrane in the region of the jawbone ridge consists of an evaluation instrument and a hand probe interconnected by a cable. The hand probe has a probe housing and an ultrasonic oscillator fitted therein on which are arranged a damping member on the back and a lead member on the front, in which the lead member forms a coupling surface for coupling to the mucous membrane and consists of a material with an acoustical impedance corresponding to 0.3 to 3 times the value and preferably 0.5 to 2.4 times the value of the acoustical impedance of water. A control electronic system and an evaluation electronic system, an electric power supply and a display unit are fitted in the evaluation instrument.
