  • Patent number: 11155723
    Abstract: Resin formulation including: a mixture of low volatility oligomers is about 40% to 75% weight of the resin formulation; a plasticizer is about 25% to 55% by weight of the resin formulation; a photoinitiator is about 0.1% to 3.0% by weight of the resin formulation; a thermal inhibitor is about 0.001% to 4% by weight of the resin formulation; and a defoaming agent is about 0.0001% to 0.1% by weight of the resin formulation. Wherein the mixture of low volatility oligomers is combined with the photoinitiator, the thermal inhibitor and the defoaming agent, and mixed, then degassed at a temperature of about 60 deg C. and at a pressure of less than 10 kPa for at least 10 minutes.
    Type: Grant

  • Patent number: 9271812
    Abstract: A modified dental implant fixture designed to preserve lingual bone by having the coronal aspect of the implant being compatible with bony anatomy that is higher on the lingual side of the implant surgical site. The implant may be of either the single stage or the two stage design. By modifying the shape of the top of the implant fixture to mimic healing/healed bony anatomy, bone is preserved and bone growth is possibly encourage.

  • Publication number: 20050004712
    Abstract: A method and apparatus for determining time remaining for hot water flow at a particular temperature. A first, water outlet sensor system 22 is located near a water outlet such that temperature sensor 24 senses the water temperature of water flowing to a water outlet 14. A second, water heater sensor system 34 is located near a water heater storage vessel 18 for sensing the water temperature of water exiting the storage vessel 18. Water heater sensor system 34 includes a logic controller 38 for determining time remaining for hot water flow based upon sensed temperatures at water outlet 14 and storage vessel 18. Display device 42 provides information received from controller 38 and from water outlet sensor system 22. First and second sensor systems 22, 34 and display device 42 communicate via radio frequency communication link 29.
