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.

The application discloses a combined digital guide plate system for free gingival grafting and belongs to the technical field of stomatology. The combined digital guide plate system for free gingival grafting comprises a base guide plate, a recipient site semi-thick incision indicating guide plate, a recipient site full-thickness incision indicating guide plate, a temporary restoration-soft tissue fixation clamping plate and a donor site indicating guide plate; the base guide plate is used for positioning and fixing the guide plates and the temporary restoration-soft tissue fixation clamping plate of the recipient site. The application covers the recipient site semi-thick incision indicating guide plate, the recipient site full-thickness flap incision indicating guide plate, the temporary restoration-soft tissue fixation clamping plate and the donor site indicating guide plate, and realizes the functional integration of the whole free gingival grafting treatment process in combination with the composite structure design of the base guide plate and the split accessory guide plate. The application can realize accurate positioning, avoid damaging anatomical structures, accurately prepare semi-thick flaps and full-thickness flaps, shorten the tooth loss period of the patient, prevent the rebound of the vestibular groove, and ensure the curative effect of the free gingival grafting.

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.

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.
