The present invention provides methods for acquiring and utilizing time-based 3d jaw motion images (4d datasets) to enhance the computer-aided design (CAD) of dental devices, which may include dental restorations, oral prostheses, and oral appliances. These 4d datasets may be used directly to provide a jaw motion model suitable for enhanced CAD or, they may be used to derive mathematical expressions that are then used to drive a motion simulation. The methods of the invention are based on acquiring time-based 3d images (a 4d sequence) of the upper and lower teeth, with each 3d frame in the time sequence capturing some upper and lower arch anatomy (the oral anatomy). Each image in the 4d sequence may therefore contain an accurate record of the relationship between the upper and lower arch in three dimensions.

An electrolytically activated, microcidal aqueous solution is disclosed which is used in the elimination and control of biofilm in dental unit water lines. The solution has a pH between 6.75 and 10 with microcidal as well as anti-oxidising, dispersing and surfactant properties, rendering the solution bio-compatible and non-corrosive, as well as capable of eliminating biofilm in dental unit water lines, while simultaneously dispersing and dislodging the biofilm from the water lines so as reduce the micro-organisms in the dental water to a predetermined level. The aqueous solution is produced using an electrolytic device that allows the independent manipulation of specific individual properties of two separate product streams (a cation-rich stream and an anion-rich stream), the manipulation being performed by separate and independent recirculation through the same electrode chamber or counter-electrode chamber of the electrolytic device to modulate the respective properties of the anion-containing and the cation-containing solutions.

The present invention relates to a wireless remote control for dental equipment, such as dental scaler tools, dental drills, prophy angles and other rotary instruments. The wireless control switch can control the on and off state of the dental tool, or it can also be programmed to control the speed of the tool by a switch on the tool. The wireless control switch can be in the form of, for example, a foot switch, and replaces manual and foot operated controls formerly connected by cables to the dental tools. This removes a potential safety hazard in the dentist's office and makes the equipment control more versatile and easier to adapt to various office conditions. The wireless control can be battery powered, further eliminating the need for cables.

A method of producing a stream of aqueous chlorine dioxide sterilizing fluid suitable for use in sterilizing medical and dental equipment or for wound irrigation or skin asepsis is described. Steps are: pumping fluid portions of a first reagent and a second reagent into the proximal end of an elongate reaction chamber (24) to form a reaction mixture, the reagents being selected to react together to form aqueous chlorine dioxide; providing a stream of water around or adjacent to the distal end of the reaction chamber (24); continuing to pump fluid portions of said reagents so as to cause the reagent mixture to travel through the reaction chamber and then into the stream of water to form a stream of aqueous chlorine dioxide sterilizing fluid; wherein the pumping rates and the internal dimensions of the elongate reaction chamber (24) are selected so that the reaction to form chlorine dioxide is substantially complete when the reagent mixture exits the reaction chamber (24); and continuing pumping fluid portions of said reagents until a desired quantity of said sterilizing fluid has been produced; wherein the pumping of each reagent is carried out by means of a diaphragm pump (90, 92) or a piston pump via a pressure-control valve (32, 34) so that each fluid portion is pumped at substantially constant pressure.
