The invention discloses a process for producing dental shaped parts which consists entirely of porous glass without crystalline portions. The density of the blank is between 50% and 95% of its theoretical density. It has a discoidal shape with a diameter of at least 20 mm.

The blank is produced by a process in which glass powder is first pressed at a pressure of between 10 MPa and 300 MPa and this green body is (pre-)sintered at a temperature of between 580° C. and 750° C. to form a blank of porous glass without crystalline portions.

From the obtained blank, monolithic dental shaped parts can be obtained by mechanical processing followed by sintering, wherein a process according to the invention for stabilizing the shape of the shaped parts is used.

The present invention relates to a hydrogel formulation in which the solid phase is composed of a continuous net work of siloxane bonds and one or more calcium phosphate phases doped with one or more metal dopants.

An adsorption method adsorbs a substance by using a tube-shaped apatite crystal. The apatite crystal may be a monocrystal given by a general formula M.sup.2.sub.5(PO.sub.4).sub.3X (M.sup.2 denotes at least one element selected from the group consisting of divalent alkali earth metal and Eu, and X denotes at least one element or molecule selected from the group consisting of halogen element and OH). The outer form of the apatite crystal may be a hexagonal prism in which the aperture of a hole formed on a top surface or bottom surface of the hexagonal prism may be hexagonal.

Provided is an implantable composite which includes a plurality of resorbable ceramic particles with or without a biodegradable polymer. The resorbable ceramic particles can be granules including carbonated hydroxyapatite and tricalcium phosphate in a ratio of 5:95 to 70:30. Some resorbable ceramic particles are granules, which include carbonated hydroxyapatite and β tricalcium phosphate in a ratio of 5:95 to 70:30. The resorbable ceramic particles have a particle size from about 0.4 to about 3.5 mm. The implantable composite is configured to tit at or near a bone defect as an autograft extender to promote bone growth. Methods of using the implantable composite are also provided.
