Abstract: In a method of restoring a tooth, the present invention provides a technique  for the removal of cement after bonding a dental construct to a tooth. The effect of 5 cement removal techniques were determined by means of an in vitr o study, using extracted human teeth. The best results in terms of leakage scores and interface contour were obtained by the technique disclosed, comprising the following steps: after placement of the construct on the toot h, removing excess cement with a soft, pointed brush, brushing the dental margi ns with a photocurable dental resin cement which is the same as or different fr om the dental cement used to bond the construct to the tooth; and, light curing  the photocurable dental resin cement. When using resin or resin ionomer dent al cements, the technique of cement removal disclosed yields improved marginal adaptation of the cement and a good marginal seal.

Filed: 2002-09-11
Abstract: A mobile passenger ramp for loading and unloading aircraft, the comprising having upper and lower frame sections connected pivotally so that the ramp can be folded for storage or movement about the tarmac and unfolded at an obtuse angle to form a wide "footprint" to provide wind or jet blast stability. An arcuate surface bridges between the ramps of the two frames when unfolded.     The compact ramp remains safely clear of a "No-Go" zone while still being sufficiently long to minimize the slope of the ramp for improved ease of use by passengers, either ambulatory or in wheelchairs. A steerable wheel at one end of the ramp enables rotation of one frame about the pivoting connection for folding and unfolding the frames. Fixed wheels on the upper frame and a castored wheel positioned near the pivot point on the lower frame provide stability and easy maneuverability of the folded ramp.

Filed: 2002-12-20
Abstract: A dental handpiece is disclosed with a turbine construction wherein a radial airflow into the turbine about the whole circumference of the turbine is created, which generates additional torque and simultaneously centralizes the turbine wheel. The turbine is supported by a pair of axially spaced air bearings which are controlled in such a way that the air bearings are floated before drive air is supplied to the turbine and after drive air to the turbine has been shut off. This ensures that the air bearings are always operational irrespective of the operational state of the turbine. The handpiece has an improved ergonomic shape, especially the shape and configuration of the front or head portion, which provides additional tooth clearance arid a better field of view. An angled swivel connection to the umbilical cord is provided to reduce physical strain on the dentist's wrist. A lock and key type torque connection between the dental burr and chuck is provided which accommodates both conventional burrs and the burr of the lock and key arrangement. An auto stop arrangement for the turbine is disclosed which prevents a vacuum build-up during run-down of the turbine. The specific construction of the auto stop valve in accordance with the invention closes both the drive and exhaust air conduits.
