Abstract: The present invention is an improved implant made from regenerative tissue or natural tissue, methods of making the implant, and methods of using the implant.

Abstract: A printing system that comprises a media transport system for conveying a print media along a media path in a first direction. A plurality of print modules each spanning the print media path along a second direction. Each print module defines a major axis along the second direction. A minor axis that aligns along the first direction and an intermediate axis with each of the print modules. A printhead array that includes printheads spaced from the media path. A fluid regulator portion configured to regulate a fluid pressure in the printhead portion. Each of the print modules are configured to be installed into and removed from the printing system as an integral unit.

Abstract: A printing system that comprises a media transport system configured to transport media along a media path. A printhead module that has a fluid inlet and spanning the media path. An ink delivery system that provides ink to the printhead module that includes a main ink supply and a buffer tank. A first pressure regulation unit that includes an overflow weir over which fluid flows from a fluid chamber to a sump. The fluid chamber is fluidly coupled to the fluid inlet whereby a height of liquid in the fluid chamber regulates a pressure at the fluid inlet. An ink supply control module coupled to the main ink supply, the buffer tank, and to the pressure regulation unit and controlling fluid flow in fluid paths that includes a first fluid path that supplies ink from the main ink supply to the buffer tank. A second fluid path that supplies ink from the buffer tank to the fluid chamber. A third fluid path that receives ink from the sump and returns the ink to the buffer tank.

Abstract: Methods and systems are described to digitally model the 4-dimensional dynamics of jaw and tooth motion using time-based 3-dimensional data. Complete upper and lower digital models are registered to time-based 3-dimensional intra-oral data to produce a true 4-dimensional model. Diagnostic and clinical applications include balancing the occlusion and characterizing the geometry of the temporomandibular joint. The 4-dimensional model is readily combined with conventional imaging methods such as CT to create a more complete virtual patient model.

Abstract: A digitally-based method is described for the design and production of customized removable dental appliances. The plastic component of custom appliances is designed using software, and milled directly over a plaster model of the dentition. A patient's upper, lower, and bite-registered arches are digitized, registered to a bite or centric occlusion position, and articulated in software using either an average geometry or the geometry of a specific articulator. Appliance design is performed by defining the desired plastic surfaces and margins as dictated by the relative movement and positions of the arches as functionally required for a specific appliance. Standard CAM software is used to read the design file and command a multiaxis machine center to mill the plastic while directly on a plaster model.
