5 results about "Temporary restoration" patented technology

The invention belongs to the technical field of computer aided design, and provides a generative adversarial network-based personalized dental restoration intelligent design method, which comprises the following steps of: marking a difference set part connected with a temporary restoration region in a wearing three-dimensional model as a carrying model; carrying out combined Boolean operation on the temporary restoration body area and the undertaking model to obtain a combined part, and recording the combined part as a stress model; identifying a stress shielding area on the stress model according to the stress nephogram; performing elastic correction on the stress shielding area of the temporary restoration area to obtain a three-dimensional model of the dental restoration; the wall thickness of the strong sub-region with an unstable stress path caused by overall stress shielding is corrected through the wall thickness difference value of the corresponding elastic correction weak sub-region, the problem that overall stress shielding is converted into a local stress peak value is reduced, stress transmission is uniform, and the problem that stability fluctuates due to the fact that the stress path changes along with time is solved.

The invention discloses a transgingival three-dimensional shape shaping tool box for a temporary prosthesis and a manufacturing method of the transgingival three-dimensional shape shaping tool box. Comprising a body and a shaping groove, the shaping groove is formed in the body, and the shaping groove is used for providing a placement space for an implant substitute and simulating the structure of a natural tooth penetrating gingival three-dimensional form; wherein the body comprises an upper body and a lower body; the upper body and the lower body are detachably connected; the shaping groove comprises an implant replacement body placing structure and a gum-penetrating contour forming structure, the implant replacement body placing structure is connected with the periphery of the gum-penetrating contour forming structure, the implant replacement body placing structure is used for placing an implant replacement body matched with an implant, and the gum-penetrating contour forming structure is used for accommodating a temporary repair abutment connected with the implant replacement body; and a natural tooth gingival penetrating three-dimensional form is simulated.

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.
