Abstract

The present invention discloses a midfacial expander device with temporary anchorage devices (TADs) and protraction wire support assembly. The device comprises at least one alignment rod and at least one sleeve to receive the alignment rod therein. The device comprises a first expander body and a second expander body to receive the alignment rod and the sleeve. The device comprises an expansion screw assembly extending between the first and second expander bodies. The device further comprises a first anchor body and a second anchor body to support the respective first expander body and second expander body. The device comprises assembly screws to fasten the expander body to the anchor body. The device comprises temporary anchorage devices for application of the device to the patient's maxilla

Abstract

The present invention discloses a midfacial expander device with temporary anchorage devices (TADs) and locked alignment rods. The device comprises at least one alignment rod and at least one sleeve to receive the alignment rod therein. The device comprises a first expander body and a second expander body to receive the alignment rod and the sleeve. The device comprises an expansion screw assembly extending between the first and second expander bodies. The device further comprises a first anchor body and a second anchor body to support the first expander body and the second expander body, respectively. The device comprises assembly screws to fasten the expander body to the anchor body. The device further comprises anchor screws and temporary anchorage devices (TADs) for application of device to the maxilla of the patient. The TADs are fixed at the respective anchor body and extend outwards with respect to the device.

Abstract

The present invention provides body anchored protraction devices. The protraction devices direct the negative forces of protraction over a large surface area on the chest and abdomen of a patient. The protraction devices employ a cantilever support rod and ultra-low friction joints to enable low compression on the head without restricting free movement.

Abstract

A door assembly includes a first door skin and a second door skin spaced apart from the first door skin. The assembly also includes an energy sensor generating an energy signature signal and a memory storing a door component operating signature. A controller is coupled to the accelerometer and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.
