The present invention relates to a method for manufacturing a zirconia slurry for forming porous surfaces on an abutment and a crown of a ceramic implant, the method including: the zirconia pulverization step (step S10) of putting zirconia powder, carbon powder as a foaming agent, and an organic binder in a ball mill and agitating and pulverizing the zirconia, carbon powder, and organic binder to allow the mixed zirconia powder to have nanoparticles; the carbon powder oxidization step (step S20) of heating the zirconia powder mixed with the carbon powder to a temperature of 1200 to 1800° C. and oxidizing the carbon powder to a concentration of 10 to 40 wt % to allow the porous surfaces to be formed on every particle of the zirconia powder; and the degreasing step (step S30) of putting a dispersing agent and a solvent in the zirconia powder whose particles have the porous surfaces to make a zirconia solution and removing the organic binder from the zirconia powder.

A composite polishing strand has a polishing strip for polishing a dental restoration, such as a filling, and may incorporate a floss leader coupled to a polishing strip. The floss leader may be snapped down between teeth and the polishing strip may then be pulled into the interproximal contact area for polishing a dental restoration. A composite polishing strip may also include a threader having an insert end that can be inserted into an interproximal contact area, such as an interproximal subjacent contact area, and pushed through to the opposing side. The threader may then be pulled to locate the polishing strip in the interproximal contact area for polishing the dental restoration. The composite polishing strip having both a threader and floss leader enables two different methods of locating the polishing strip in the interproximal contact area and therefore is very versatile.

The present disclosure provides an additive manufactured article including a first portion and a second portion integral to the first portion. The second portion includes a coupling configured to engage a tool, as well as a frangible section at a connection point to the first portion. Further, a method of making the article is provided, including obtaining a photopolymerizable material and selectively curing the photopolymerizable material to form the article. Another method is provided, including obtaining a digital three-dimensional model of a patient's dental anatomy comprising a tooth in need of restoration and computing a digital three-dimensional model of a dental restoration to fit within the patient's dental anatomy, including determining a shape of the dental restoration. Optionally, the patient's dental anatomy may be prepared for a dental restoration prior to obtaining the digital three-dimensional model. A kit is also provided, including the article and a tool configured to attach to the coupling of the article. Having a coupling integral to the rest of the article allows for easy attachment to a handling tool.

Disclosed is an assembly and method for fabricating a dental prosthesis, such as composite veneer directly in a mouth. The assembly includes a base that can be worn in a mouth, the base configured to fit around a base line. The base forms an enclosed body around teeth to be treated. The assembly further comprises a handle configured to secure to the base. The handle comprises an orienting arm that carrier a shell attach to its tip. The base and the handle are configured such as when the handle is secured to the base, the shell is placed over the tooth in a predetermined position.

Dental instrumentation for use in guiding a cutting tool to remove tooth structure from a working tooth is prepared. A digital model of cutting guide shell structure for placement around a portion of the tooth to be treated is combined with preset tool movements to be made by the cutting tool by one or more processors to define final cutting guide data corresponding to final cutting guide structure for guiding the cutting tool. A digital model of a fixation instrument configuration for fixing the dental instrumentation to an adjacent tooth to the working tooth is combined with the final cutting guide data by one or more processors to define final instrument configuration data corresponding to a final instrument configuration for releasably fixing the dental instrumentation to the adjacent tooth and for guiding the cutting tool in the removal of the tooth structure from the tooth to be treated.

A matrix adapted is for the specific tooth type, and is positioned on the tooth to covers the tooth, so that an injected curable material is encased by the matrix over the tooth. When the curable material has cured, the matrix is removed, resulting in a veneer on the tooth.
