Abstract: A method and system of ordering a dental prosthetic from a dental laboratory, by which a prescription for a patient dental prosthetic is entered by a dentist, and stored and communicated to a dental laboratory. The receiving dental laboratory may subsequently communicate the dental prosthetic prescription to one or many authorized subcontracting laboratories and suppliers. The initiating dentist may seek collaborative guidance from one or many experts in the field of dental prosthetics. The experts are granted authorization to view the prescription data and communicate between each other and the dentist to provide the requested guidance.

Abstract: The present invention provides a microkeratome for creating lamellar sections from a biological tissue containing a blade-post assembly which improves precision and predictability by preventing undesired blade wobbling. Methods and devices are disclosed to inhibit blade wobbling, preferably frictional fittings are employed to secure the blade (or blade assembly) within the microkeratome. By biasing the blade into a secure position, wobbling during usage is substantially lessened if not eliminated. A modified blade assembly is disclosed having a post that is mated to a surgical blade. In one embodiment of the invention, the post can have one or more protrusions that engage at least one side of a recess in the microkeratome thereby creating a frictional fit sufficient to prevent movement of the blade while cutting. In another embodiment of the invention, the recess can include certain biasing elements that engage the post to prevent blade wobbling.
