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.

This invention provides a method for implanting a dental prosthesis, comprising: a first step of setting multiple implantation information along the dental arch in a three-dimensional planning image; a second step of flattening the alveolar bone and implanting the dental implants, and fixing a support device including a support abutment and a fixing rod to the upper side of the dental implants; a third step of modifying a temporary prosthesis to form a temporary mounting portion for inserting the support device on the inner surface of the temporary prosthesis; a fourth step of acquiring a modified scan image from the modified temporary prosthesis scan image in which the three-dimensional shape information of the temporary mounting portion is exposed externally, and exchanging the three-dimensional shape information of the temporary mounting portion with the virtual support device; and a fifth step of fixing the artificial tooth portion to the artificial gingiva to manufacture the final dental prosthesis, wherein the artificial gingiva portion has a mounting portion formed based on the virtual support device and is fixed with clips.

A method of manufacturing a permanent prosthesis for attachment to a dental implant installed in a mouth of a patient includes scanning a patient specific temporary prosthesis (PSTP) to obtain scan data. The PSTP is attached to the dental implant in the mouth of the patient. Gingival tissue surrounding the PSTP is permitted to heal in the mouth of the patient. In response to aesthetics of the healed gingival tissue surrounding the PSTP in the mouth of the patient not being acceptable, the PSTP is physically modified by (i) removing material from the PSTP, (ii) adding material to the PSTP, or (iii) both. The modified PSTP is scanned and a permanent prosthesis is fabricated as a replica of the modified PSTP using scan data generated from the scan of the modified PSTP.

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.

To improve the accuracy of dental restoration, the present application provides a method for manufacturing a dental restoration prosthesis, comprising: a first step of generating design information of a temporary prosthesis; a second step of correcting the position of a temporary bonding portion formed in the manufactured temporary prosthesis to correspond to the implant information of the implant; a third step of forming a confirmation model aligned and fixed to a base model, and acquiring a first auxiliary scanning image of the confirmation model; a fourth step of virtually overlapping a virtual support portion at the lower part of a virtual restoration portion, and virtually correcting the position of a virtual bonding portion included in the virtual support portion based on the first auxiliary scanning image; and a fifth step of manufacturing and assembling a metal support portion and a restoration portion, thereby manufacturing a dental restoration prosthesis.

This provides a method for preparing dental prostheses. [Solution] The method includes performing a first scan of a plurality of scannable temporary abutments, each having a scannable member, positioned on each dental implant. The method includes performing a second scan of temporary prostheses positioned on the plurality of scannable temporary abutments, each having a scannable member. The method includes generating a model of the final prosthesis based on the first and second scans using computer-aided design (CAD) software.
