The invention relates to a method for producing a monolithic form body, in particular a dental restoration, comprising the steps of: providing of a blank, producing of the form body through pressing and/or machining of the blank, and softening of the form body exclusively in its surface region by irradiation with infrared radiation.

An implant device configured to be at least partially in contact with bone on implantation has an improved osteoinductive feature to enhance new bone formation. The implant device has one or more bone growth surfaces extending from a structurally solid feature of the implant device. The one or more bone growth surfaces are configured to mimic adult trabecular bone by having trenches, grooves or surface recesses or prominences exhibiting numerous structural elements or walls not perpendicular to the surface that are non-coplanar or arched extending 20 to 500 microns in depth having an increasing inclination from the surface extending inwardly and not parallel to opposing or adjacent walls forming a random or non-random network. The one or more bone growth surfaces configured to mimic trabecular bone have discernable nano features on the structural elements or walls exhibiting nano scale features of less than 200 nano meters within the network.

A method for making a rapid prototype of a patient's mouth to be used in the design and fabrication of a dental prosthesis. The method takes an impression of a mouth including a first installation site having a dental implant installed in the first installation site and a gingival healing abutment having at least one informational marker attached to the dental implant. A stone model is prepared based on the impression, including teeth models and model markers indicative of the at least one informational marker. The model is scanned. Scan data is generated from the scanning. The scan data is transferred to a CAD program. A three-dimensional model of the installation site is created in the CAD program. The at least one informational marker is determined to gather information for manufacturing the rapid prototype. Rapid prototype dimensional information is developed. The rapid prototype dimensional information is transferred to a rapid prototyping machine which fabricate a rapid prototype of the patient's dentition as well as a dental implant analog position.

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.

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 three-dimensional orthodontic retainer (2) and to a method for producing such a retainer (2) in which the three-dimensional orthodontic retainer (2) is matched to the exact shape of the adjacent teeth (3) and is produced from a blank (1) in such a manner that the physical properties of the material of the remaining part of the blank (1) are unchanged in the retainer (2). The method for producing the three-dimensional orthodontic retainer (2) comprises the following method steps: creating a three-dimensional model of the structure of the patient's teeth (3); designing a customised, precisely fitting model of the retainer (2); producing the retainer (2) on the basis of the designed 3D model by computer-controlled deposition or application of material.

Method for manufacturing dental prostheses, comprising the following operations: defining a layered numerical representation of a dental prosthesis (11); for a first layer of the numerical representation, prepare a corresponding layer of a light sensitive liquid substance (6); selectively solidify the layer of liquid substance (6) to obtain a first sheet (7) having a geometry corresponding to the geometry of the first layer of the numerical representation; repeat the operations of preparing a layer of liquid substance (6) and selectively solidify the layer of liquid substance (6) for each subsequent layer of the numerical representation to obtain corresponding sheets (7); cause the mutual adhesion between said sheets (7); modify the composition of the liquid substance (6) after having solidified one of the sheets (7) and before solidifying the subsequent sheet (7), so as to modify one or more optical properties of the liquid substance (6).
