Good passive in-place of the implant restoration is a prerequisite for long-term stability of the implant restoration, reduction of various mechanical and biological complications. The accurate prosthesis is manufactured on the accurate model, and good passive in-place of the implanted prosthesis in the mouth can be realized. The precision of the implant impression is influenced by many factors, such as the number of implants, the angle of the implants, the design of the transfer device, the impression material, the method and skill of taking the impression, etc. The passive positioning of a single implanted prosthesis is relatively easy, but when a patient with a plurality of teeth continuously lost is implanted and repaired, in order to realize the common passive positioning of the plurality of prostheses, a complicated model taking process and a prosthesis manufacturing procedure are needed.

When a plurality of implants are repaired at the same time, the clinical multi-purpose method is to use the windowing impression technique and connect a plurality of implant transfer devices by using connecting materials cured in the mouth so as to obtain stable relative position relationship between the implants, thereby obtaining more accurate impressions and models. Self-curing polymethacrylic resin materials are used in clinical practice, but the materials have large polymerization shrinkage and heavy odor stimulation, are not suitable for long-time operation in the mouth, and therefore, a secondary impression is generally required.
