Disclosed are a dental gradient color-resin ceramic restoration material and a preparation method thereof. The method includes: preparing at least two paste materials with different colors, respectively dispersing the paste materials with different colors at a certain speed and under a vacuum of -0.01-0.1 MPa to obtain at least two granular materials with different colors having an average size of 0.1 mm to 5 mm; spreading the at least two granular materials with different colors to be flat in a mould in sequence to obtain at least two layers, and then tightly combining the at least two layers at a pressure of 0.5-5 MPa to obtain a semi-finished product of a gradient color-resin ceramic restoration material; polymerizing and curing the semi-finished product at 60-200° C. and 2-50 MPa to obtain a multilayer gradient color-resin ceramic restoration material.

A dental implant includes an insert element of a titanium-based material inserted and soldered into a blind hole in an anchoring element of a ceramic. The insert element has spacer members to center it in the blind hole, with a uniform circumferential gap space relative to the anchoring element. A portion of the insert element protrudes outwardly beyond an end face of the anchoring element. The blind hole is partly filled with a glass solder, and the insert element is inserted into the blind hole, whereby some of the glass solder is displaced out of the gap space onto the end face of the anchoring element and the protruding portion of the insert element. A thermal soldering process secures the insert element into the anchoring element. The protruding portion of the insert element and remaining excess solder are removed to form a planar surface.

One aspect of the invention includes a glass powder for a chemical polymerization initiator, the glass powder including aluminum, silicon, and at least one of copper or vanadium.

A dental filling material comprising bioactive borate glass particles, wherein the particles are at a concentration of 40-60 wt %, a co-monomer resin blend, a photoinitiator, and a co-initiator is provided. Method for applying the dental filling material to a tooth structure are also provided. The temporary filling material re-mineralizes the tooth structure and is removed after 1-7 days for the placement of a permanent filling material.
