Systems for laser trimming dental aligners
A system includes an orientation determination system comprising a camera where the camera is configured to capture an image of an orientation feature of a physical dental model of a dental arch of a customer with material thermoformed thereon. The orientation determination system is configured to identify an offset of the physical dental model with respect to a fixture plate during positioning or before or after the physical dental model is positioned on the fixture plate by determining an actual orientation of the physical dental model based on the orientation feature. The system also includes a laser trimming system configured to cut the material along a trim line based on the identified offset while the fixture plate is moved about at least two axes to produce a dental aligner specific to the customer and being configured to reposition one or more teeth of the customer.
Method of manufacturing an article
A method of manufacturing an article comprising: (a) performing an additive manufacturing process to firm an article in an initial state, the article comprising mounting features and being supported during the additive manufacturing process by support structures; and (b) performing a second manufacturing process to transform the article into a second state, which second manufacturing process is a subtractive process comprising: (i) mounting, via the mounting features formed during the additive manufacturing process, the article in a holding device of a machine for operating on the article, with the support structures or at least remnants thereof remaining on the article, and (ii) with the article so mounted in the holding device, processing at least one feature on a surface of the article on which the support structures were provided to remove material on the at least one feature provided by the support structures.
Implant made of fibre-reinforced plastic
A customizable implant made of plastic including a thermoplastic which is reinforced with long fibers arranged multidirectionally in a targeted manner and has a modulus of elasticity E of 10-70 GPa is provided. A system for producing a customizable implant including a device for collecting patient data regarding the environment into which an implant is to be inserted, a computer program for creating a model for a customized implant based on the patient data collected, and a device for producing the customized implant based on the calculated model by means of 3D printing and/or laser sintering is also provided.
Biological tissue rootage face, implant, method for forming biological tissue rootage face, and method for producing implant
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.
Methods of fabricating a 3D device using ablation
A three-dimensional device is fabricated in a layer-by-layer approach using a support material. The support material is deposited in a liquid form on a surface, hardened by cooling or ultraviolet (UV) curing, and selectively ablated to create an area within which the desired structure of the device will be formed. Active material is deposited into this area, and the layer-by-layer process repeated until the three-dimensional device has been completed. Thereafter, any remaining support material is removed by water or other solvent.
Plate for production of a dental implant and/or artificial prosthesis
The present disclosure concerns a set for the production by 3D printing of implant abutments for dental implants, the set including at least one abutment having an elongated base member with an axis, and at least one positioning element fixed to the base member; a plate with at least one recess and a locking portion; where the recess is larger than the elongated base member and where the locking portion is configured to be in a form fit connection with the positioning element in order to vertically position the abutment, and lock the abutment in rotation around its axis.
METHOD FOR PRODUCING A CERAMIC FIXED PARTIAL DENTURE
A method for making ceramic fixed partial dentures comprising separating the as-sintered partial denture structure, rejoining the retainers and pontic with glass, which forms a strong joint between the retainers and pontic after sintering. This method may produce ceramic long-span fixed partial dentures with a better fit.
High productivity system for printing precision articles
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.
Digital integrated molding method for dental attachments
A digital integrated molding method for dental attachments includes 3D design, aiming at acquiring 3D data of an attachment itself through 3D scanning of an attachment preform, carrying out modeling design directly on the basis of acquired data, adjusting corresponding positions of an inner-crown and an attachment, or a bridge and an attachment by design software, and directly designing the attachments of the inner-crown and the bridge into a whole; data processing, aiming at slicing the integrated inner-crown and attachment or bridge and attachment for additive manufacturing; and additive manufacturing, aiming at processing an integrated inner-crown, bridge or attachment. The molding method can greatly improve the molding accuracy of dental attachments, and ensure the relative accuracy of inner-crowns, bridges or attachments.
METHOD AND SYSTEM FOR PROCESSING DENTAL PROSTHESES
A system and method for optimising the preparation of dental restorations is provided. The system comprises a dental restoration surface processing unit, a dental restoration assessment unit, a database comprising a treatment parameters database and a processing protocols database, a processor operationally coupled to said dental restoration surface processing unit and a protocol selector. The method treats a dental restoration surface using the system and according to one or more selected processing protocol.
