Abstract

The invention discloses a method for preparing a precise impression of an implant fixed bridge. The method comprises the following steps: preparing an implant restoration impression; filling a plaster model; selecting an abutment; making a metal bridge and a plastic in-position small body; guiding the abutment to be in a mouth by the in-position small body, applying a torque, and removing the in-position small body; enabling the try-in metal bridge to reach the abutment and closely contact the abutment; bonding the metal bridge onto the abutment in the mouth to form an abutment-metal bridge combination body, and taking the combination body as a transfer device; preparing the precise impression of the implant fixed bridge. The method can be used for improving the accuracy of the impression of the implant fixed bridge. According to the method, rigid connection between abutments is realized, the bending strength of the transfer device is improved, the influence caused by deformation of an impression material can be eliminated, the deformation of model plaster can be resisted, and loosening and shifting between connection devices are avoided, thereby improving the accuracy of the impression during implant fixed bridge repairing.

Description

technical field [0001] The invention belongs to the field of implant denture restoration, in particular to a method for precision impression of an implant fixed bridge. Background technique [0002] The passive placement of implant dentures is an important condition for successful implant restoration, and it is especially important for implant fixed bridge restoration. [0003] Prosthetic accuracy is a prerequisite for passive seating. [0004] The improvement of the accuracy of the restoration involves many aspects, the most important of which is to improve the accuracy of the model. The accuracy of the model first depends on the accuracy of the impression. Acrylic resin splint transfer impression technology is one of the commonly used accurate impression methods for implant bridge restoration. However, due to the shrinkage deformation and low deformation resistance of acrylic resin during the polymerization process, whether this technology can improve the accuracy of the...
