Overview
The bionic healing abutment of the group's previous research results has both soft tissue shaping and impression taking functions, realizing the advantages of no need to dismantle the impression, simplifying clinical operation, maintaining soft tissue closure and reducing patient discomfort, responding to the requirements of the new quality productivity. On this basis, this study is intended to explore the accuracy of implant restorative impressions with bionic healing abutment and transfer bar in the impression of membrane material, and with bionic healing abutment and scanning bar in the digital impression in the case of different parts of the missing teeth and different numbers of missing teeth, so as to provide a basis for the application of bionic healing abutment in implant restorative impressions and guidance on the use of the clinic.
