Abstract: A telescopic oral orthopedic appliance aligns the upper and lower jaws for treatment of the temporomandibular joint. It includes an extensible-contractable positioning device which extends between and alters the position of the mandible relative to the maxillae. The device is attached to upper and lower sets of teeth by an anchor which is embedded in a pair of opposing channel members which fit over the apex and inwardly and outwardly facing walls of the clinical crowns of a series of adjacent teeth. The extensible-contractable device fits closely against the channel member to avoid rubbing the buccal mucosa of the wearer's mouth. The length of the device is selectively variable to alter the position of the mandible forward or backward without sudden jumps or the need for removing the appliance from the mouth.

Abstract: An ultrasonic device includes an auxiliary chamber for receiving an additive in tablet form. The ultrasonic device includes an ultrasonic tool which is connected to an ultrasonic vibrator by a shank. A sleeve surrounds the shank and defines an annular space therewith. Cleansing fluid, in particular water, flows through the annular chamber and exits in the area of the tool. The auxiliary chamber is formed by an axial bore extending through the sleeve and communicating with the annular chamber. A cap closes the outer end of the bore and the bore is dimensioned for receiving a tablet containing the additive. Some of the fluid in the annular chamber passes through the auxiliary chamber to dissolve the tablet and introduce the additive into the stream of fluid before it is discharged at the ultrasonic tool.

Abstract: An erection aid comprises an annnular elastic tube which is inflatable to apply pressure to the base of the penis, reducing venous flow of blood while permitting arterial flow. A valve is provided for inflation. The annular tube is made with non-uniform wall thickness so that the inwardly facing portions of the wall are thinner and more easily deformable, permitting the desired pressure to be applied while minimizing axial deformation and thereby minimizing interference with normal functions. The thicker portions of the tube are sufficiently elastic to allow diametral increases as the penis becomes erect.

Abstract: The housing of an oral hygiene device is attachable to a water faucet. A regulator within the housing responds to the water which is subject to pressure variation. The regulator accommodates that variation in developing automatically a stream of water at a constant pressure. A turbine within the housing is caused to rotate in response to energy in the stream. A piston pump draws water deflected by impellers on the turbine and forms that water into a series of pulses. A flexible hose coupled to the housing includes a handle for directing the pulses against the teeth and gums of a user at a desired pressure.
