The invention belongs to a material self-healing performance evaluation method, and particularly relates to a dental self-healing material self-healing performance multi-element evaluation method, which comprises the following steps: making a dental self-healing material into a test piece for multi-element evaluation; preparing scratches on the surface of the test piece to simulate microcracks, and then performing self-healing on the test piece with the scratches; the healing state of the dental self-healing material is obtained in the self-healing process, and the obtaining mode comprises the steps of (1) obtaining a test piece image through a stereoscopic microscope, (2) obtaining a test piece model through a dental laboratory scanner, and (3) obtaining the fracture toughness of the test piece through a three-point bending test; calculating healing efficiency in different modes; and setting an influence weight based on different healing efficiency acquisition methods, and calculating the total healing efficiency. Compared with the prior art, the problems that the practical application scene of the dental self-healing material in the oral cavity cannot be reflected and the form is single in the prior art are solved. According to the scheme, healing efficiency evaluation is performed on the self-healing performance from multiple angles, so that the condition of the dental material in the actual scene of the oral cavity is better met.

A method for commissioning production of a dental prosthesis according to one embodiment of the present disclosure may comprise the steps of: generating a case for which production of the dental prosthesis is to be commissioned; determining a dental laboratory to which the case is to be commissioned among a plurality of dental laboratories; on the basis of the determined dental laboratory, selecting dental prosthesis-related information to be provided to a first user interface; providing the first user interface for presenting the selected dental prosthesis-related information in a selectable manner; and commissioning the production of the dental prosthesis to the determined dental laboratory on the basis of selected dental prosthesis-related information.

To provide an artificial tooth dimension evaluation system, an artificial tooth dimension evaluation method, and an artificial tooth dimension evaluation program that enable the conversion of qualitative and ambiguous instructions contained in dental technician instruction books created by a dentist into objective and quantitative manufacturing dimensions for artificial teeth, thereby making the production of artificial teeth possible.SOLUTION: An artificial tooth dimension evaluation system 1 comprises artificial tooth dimension evaluation models 25a, 25b trained using teacher data sets 8a to 8c to convert the artificial tooth production level indicated in the dental technician instruction book created by dentists into an artificial tooth production dimension, and has an evaluation unit 5 that inputs dental arch data 15a to 15c, contact data 16a to 16c, bite data 17a to 17c, and fit data 18a to 18c extracted by a feature extraction unit 4a into the evaluation model, and outputs the evaluated artificial tooth dimensions as output data sets 20a to 20c.SELECTED DRAWING: Figure 1

The present invention relates to a smart system for requesting and producing dental work. More specifically, the present invention relates to a smart system for requesting and producing dental work, wherein scan information is transmitted to a dental laboratory in real time through an oral scanner, information including the production status and delivery date for dental work for each patient and for each dental laboratory can be checked in real time, the time required for inquiry to check the production and delivery status of the dental work can be reduced, and patient appointment management can be conveniently performed. To this end, the present invention provides a smart system for requesting and producing dental work, comprising: an oral scanner capable of three-dimensionally scanning and photographing the inside of the oral cavity of a scan subject; a first user terminal capable of retrieving scan information generated by the oral scanner and inputting dental work request information; a second user terminal capable of retrieving oral scan information scanned and photographed by the oral scanner and inputting dental work production information; a second user terminal capable of retrieving the dental work production information inputted by the first user terminal; and a central server capable of receiving and storing the scanned and photographed information generated by the oral scanner and capable of transmitting and receiving information to and from the first and second user terminals.

For the fabrication of prosthetic restorations, a process with the necessary software and hardware modifications is provided. This process allows the clinical surface of the required restoration to be fabricated and finalized in a commercial laboratory, a dental practice laboratory, or in laboratory-like facilities within a dental practice prior to the treatment appointment. During the treatment appointment, the cavity-facing surface (preparation interface) is adapted to the actual situation in the patient's mouth. The restoration, partially prepared in the dental laboratory, is thus delivered to the dental practice as a semi-finished product and completed there during the treatment appointment. This allows the patient to receive their final restoration directly in a single appointment, without a temporary restoration, and in a short amount of time.

The invention relates to a method for producing prosthetic restorations, together with the software and hardware modifications required for carrying out the method. By means of the method, the clinical surface of the required restoration is produced and finalised before the treatment session in a commercial laboratory, a practice laboratory, or laboratory-type facilities within a dental practice, while the side facing the cavity (the preparation interface) is adapted to the actual intraoral situation of the patient in the dental practice during the treatment session. The restoration partially finished in the dental laboratory is thus delivered to the dental practice as a semi-finished product and is completed there during the treatment session, so that the patient can be provided directly with the final restoration in one session, without a provisional restoration and within a short period of time.

It automatically recognizes the face of the worker, adjusts its position and informs the dental laboratory's magnifying glass device, which improves mobility and ease of operation through high-quality lens coatings.

Methods and systems for bi-directional integration between one or more intraoral scanners and one or more dental labs are provided. A dental product management platform connecting the one or more intraoral scanners and the one or more dental labs can: receive an instruction to create a new dental product prescription from an operator via a graphical user interface (GUI) of the dental product management platform provided on a particular intraoral scanner, receive scanned image data from the particular intraoral scanner; validate the scanned image data in real time to determine whether the scan is of acceptable quality to fabricate a dental product; and upon determining that the scanned image data is not of acceptable quality, provide a notification to the operator via the GUI to use the particular intraoral scanner to take a second scan of the patient using the particular intraoral scanner.

The present invention relates to a method for manufacturing a prosthesis for a dental implant by using a digital library including ready-made abutment three-dimensional contour information regarding ready-made abutments having various specifications. According to an embodiment of the present invention, when designing a digital library including three-dimensional contour information of a ready-made abutment including a post having a cutting surface and / or a cutting groove formed on the outer peripheral surface thereof, the digital library including three-dimensional contour information of a ready-made abutment is designed by ignoring the cutting surface and / or the cutting groove such that, even if errors occur in the process of manufacturing the prosthesis in the dental laboratory, the occurrence of early contact on the periphery of the cutting surface and / or the cutting groove between the prosthesis and the post of the ready-made abutment can be prevented.
