Multi Unit Impression copings are dental implant components used in the impression-taking stage of the implant restoration process. They are typically made of metal or plastic and come in various shapes and sizes to match the specific implant system being used. The impression copings are attached to the implant fixtures, and then an impression material is used to make a mold of the implant site. This mold is used to create a custom-fitted abutment and crown or bridge that will be attached to the implant post. Accurate impressions are crucial for the success of dental implant restorations, and impression copings play an important role in achieving this accuracy.
