Embodiment 1

[0043] This embodiment discloses a digital design method for prefabricated inlays to seal the upper repair screw holes of dental implants, which includes the following steps:

[0044]A. Obtain a digital oral model of the patient's oral cavity, which is generated based on oral data obtained by scanning the patient's oral cavity and implants. The patient's oral data can be obtained by scanning with a digital scanner.

[0045] B. Design of the complete restoration in the oral model. This step is a common method in oral implantology, and can be completed with the help of professional oral implant design software. The prosthesis to be replaced in the missing area is designed by referring to the adjacent teeth, homonymous teeth and antagonist teeth.

[0046] C. Steps for digital drilling of screw holes for complete restorations, including primary and secondary drilling:

[0047] C1: Corresponding to the installation position of the upper implant, a hole is made on the complete re...

Embodiment 2

[0053] Clinically, patients need to wear dentures, and based on the digital design of implant restorations, physical implant restorations also need to be obtained. This embodiment discloses a manufacturing method of an implant restoration, the manufacturing method includes the above-mentioned design method of the implant restoration, and thereafter:

[0054] D. Import the model of the digitally perforated restoration (that is, the digital implant restoration) into the digital cutting and layout system, and use the flat needle mode to cut and shape the base material.

[0055] A solid implant restoration can be obtained through the above method.

[0056] In one embodiment, the digital implant prosthesis imported into the digital cutting and layout system is the implant prosthesis stored in the storage medium. The storage medium stores the implant restoration model designed by the design method in the first embodiment.

Embodiment 3

[0058] This embodiment discloses a method for manufacturing an implant restoration matched to a preformed inlay, comprising the following steps:

[0059] A. Acquisition of digital oral model: scan the patient's oral cavity and implants with a digital scanner to obtain data on the patient's oral cavity and implants, and use 3D modeling software to construct the patient's oral cavity model based on the oral cavity and implant data (ie, oral cavity data) , the oral cavity model includes the patient's dentition information and implant information.

[0060] B. Digital complete restoration design: Import the oral model into the professional oral implant design software, and the designer designs the target restoration of the implant position.

[0061] C. Digital preparation hole position:

[0062] C1. A hole is made on the target restoration. The first hole is a screw hole through which the retaining screw fixes the restoration to the implant. One-time opening is a routine design t...

Abstract

The invention discloses a digital design method for closing a repair screw hole in the upper part of a tooth implant with a prefabricated inlay. It includes the steps of obtaining a working model of the oral cavity, designing the target implant restoration, and matching holes in the screw hole area. And the substrate (dental ceramics, dental metal) is pre-cut or 3D printed. The steps in clinical use include: enlarging the screw hole of the implant to the designed hole size and depth, trying-in the pre-formed inlay, filling and leveling the hole, installing the pre-formed inlay, and curing the selected adhesive And the final steps of grinding and polishing the surface of the preformed inlay. The invention is simple in design, convenient for large-scale industrial processing and manufacturing, convenient for quick installation of prefabricated inlays, does not leave too much adhesive, convenient for fast and stable sealing of screw holes, and the sealing port is beautiful, stable and has strong mechanical properties , It can also solve the problem of aesthetic closure of the labial opening of the anterior tooth screw hole, making the case of anterior tooth implant repairing the labial opening a routine indication.

Description

technical field [0001] The invention relates to the field of oral restoration and implantation, in particular to a digital design method for a prefabricated inlay that can quickly close the screw hole of the implant. Background technique [0002] With the continuous improvement of social living standards, patients with tooth loss often choose implant dentures that can be fixed without grinding adjacent teeth and can significantly improve mastication efficiency. Clinical implant denture retention methods include: screw retention and bonding. bit. There are advantages and disadvantages of the two implant denture retention methods. Adhesive retention: the advantage is that it is easy to form a passive seat due to the existence of the adhesive, and there is no screw channel on the surface of the restoration, which can maintain the integrity of the restoration and has no stress concentration area. , the aesthetic effect is good; the disadvantage is that it is inconvenient for fu...
