The invention relates to methods for preparing a three-dimensional digital model of a prosthetic denture base for fabrication using a light-based three-dimensional printing apparatus. A virtual reference model of a prosthetic denture base is prepared and manipulated to establish specific spatial orientation and angular inclination with respect to the build platform surface of the printing apparatus. Methods may include performing a corrective digital scaling process on the virtual reference model in order to achieve further improvements to dimensional accuracy in the fabrication of prosthetic denture bases.

The invention relates to a dental ceramic blank, in particular a filled milling blank, comprising at least one organic Compound, such as a polymer polymerized in the blank, for improving the machining properties of the blank. The blank has an open-pore ceramic microstructure which has 2 to 50 wt. %, based on the total composition of the dental ceramic blank, of at least one organic Compound. The invention also relates to a method for producing the blank. The milling blank according to the invention clearly exhibits improved material properties compared to unfilled purely ceramic milling blanks which have been milled into blanks for molded prosthetic parts in CAD/CAM methods

The present invention enables modification of an intraosseous implant device that is not only biologically non-inert, but can stimulate bone and vascular growth; decrease localized inflammation; and fight local infections. The method of the present invention provides a fiber with any of the following modifications: (1) Nanofiber with PDGF, (2) Nanofiber with PDGF+BMP2, and (3) Nanofiber with BMP2 and Ag. Nanofiber can be modified with other growth factors that have been shown to improve bone growth and maturationBMP and PDGF being the most common. Nanofiber can be applied on the surface of the implant in several ways. First, a spiral micro-notching can be applied on the implant in the same direction as the threads with the nanofibers embedded into the notches. Second, the entire surface of the implant may be coated with a mesh of nanofibers. Third, it can be a combination of both embedding and notching.

A biological tissue rootage face (30) capable of closely bonding to a biological tissue (H, S) is composed of a biocompatible material and has numerous fingertip-shaped microvilli (41). The microvilli (41) have tip diameters in the order of nanometers. An implant (1) has the biological tissue rootage face (30) on a surface (11, 24) configured to root into a biological tissue (H, S). In a method for forming the biological tissue rootage face (30), a surface of a biocompatible material is subjected to laser nonthermal processing carried out by emitting a laser beam in air, to form numerous fingertip-shaped microvilli (41). The laser beam is a laser beam of an ultrashort pulse laser.

The apparatus includes a first laser module, a powder supplying nozzle, a second laser module, a dust cleaning device and an air bearing device for holding the dental restoration. The second laser module includes a plurality of laser sources, and the laser sources disposed circumferentially around the first laser module, in which each laser source is equally spaced apart from one another. The present invention further provides a method for manufacturing the dental restoration, in which the method can be applied to a laser cladding process or a laser milling process.

A three-dimensional printing system includes a resin vessel, a support tray, a motorized carriage, a light engine, and a controller. The resin vessel has a lower side with a transparent sheet which provides a lower bound for photocurable resin contained within the vessel. The support tray has a lower face for supporting an object being fabricated. The motorized carriage is for supporting and vertically positioning the support tray. The light engine is for projecting radiation up through the transparent sheet to a build plane. The controller operates the motorized carriage and the light engine to fabricate the object. The object includes a vertical arrangement of dental arches suspended from the lower face and a plurality couplings that connect pairs of the dental arches.

A method of manufacturing pre-formed, customized, ceramic, labial/lingual orthodontic clear aligner attachments (CCAA) by additive manufacturing (AM) may comprise measuring dentition data of a profile of teeth of a patient, based on the dentition data, creating a three dimensional computer-assisted design (3D CAD) model of the patient's teeth using reverse engineering, and saving the 3D CAD model, designing a 3D CAD structure model for one or more CCAA on various parts of each tooth, importing data related to the 3D CAD CCAA structure model into an AM machine, directly producing the CCAA in the ceramic slurry-based AM machine by layer manufacturing, enabling the provider to deliver patient-specific CCAA's by an indirect bonding method to the patient's teeth to improve the efficacy and retention of the clear aligners.

Provided herein is a method for forming a periodic microstructure on a surface of zirconia-based ceramics, which are not easily mechanically workable, without causing thermal adverse effects. A zirconia-based ceramic having a surface periodic microstructure is also provided. A linearly or circularly polarized laser beam is irradiated to a zirconia-based ceramic surface, and periodic irregularities are formed in a spot of the laser beam. Stripe-pattern irregularities parallel to the direction of polarization can be formed in a spot of a laser beam by irradiating a linearly polarized ultrashort pulsed-laser beam to a zirconia-based ceramic surface. A mesh-like raised region and a dot-like recessed region can be periodically formed by irradiating a circularly polarized ultrashort pulsed-laser beam to a ceramic surface.

The present disclosure relates to a dental implant with electro-stimulation system by electric circuit comprising a plurality of overlapped discs wherein each disc comprises in its interior and in its upper end and lower end surfaces channels and respective holes, wherein each channel comprises an electrically conductive material comprised in said electric circuit. The channels further comprise a film that acts as a barrier between the material of the discs and the material of the electric circuit. The implant further comprises a battery or piezoelectric sensor that allows the creation of electric fields. This disclosure has the main advantage of stimulating bone growth throughout the whole surface of the implant as well as promoting an antimicrobial action through the electric fields.
