A spinal implant in the form of a spinal facet fastener is configured to hold, restrict andor limit flexion andor extension of a spinal facet joint andor immobilize movement thereof. In one embodiment, the structural filler has a refractive index substantially similar to that of the polymerizable resin, a coarse particle fraction, and a fine particle fraction having a mean particle size greater than 0. Inputting patient-specific information through a computer to the printer. The code can include code to determine that a dropzone condition from the plurality of dropzone conditions has been satisfied based on the first software object and the second software object both being moved into the dropzone region, and code to send to a server side of a network an indicator that the dropzone condition has been satisfied. As a result, upon performing optical communication, an optical transmitting apparatus and an optical communication system that can emit an illumination light at a uniform light quantity without generating a flicker of illumination can be realized. The process of the invention may also be used in combination with plasticizing agents for cellulose such as glycerol, mono- and di-saccharides, glycols, and oligomers thereof.
