Abstract: A method of making a prosthetic dental item comprises selecting a block having a square or rectangular cross-section along is extent, wherein said block comprises polyetheretherketone and, optionally, an apatite, wherein said polymeric material has a crystallinity of at least 25%. The method comprises machining the block in dependence upon data collated using digital technology. Since the crystallinity of the material selected is high, a post-machining step whereby crystallinity is increased can be avoided, and dental items of high precision can be formed.

Abstract: A dental restorative composition is provided that includes a polymerizable resin, a substantially translucent structural filler, a nanofiller having a mean particle size less than 100 nm, and at least one rheology-modifying additive. 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 0.1 μm and smaller than the mean particle size of the coarse particle fraction. The relative ratio of the coarse particle fraction to the fine particle fraction is in the range from about 12:1 to about 2:1 by volume, the particle size distribution of each fraction is essentially monomodal, and the D(90) of the fine particle fraction is less than or equal to the D(10) of the coarse particle fraction.
