Study summary

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.

Inclusion Criteria: * The patient had good oral hygiene, no visible calculus on the gingival margins, and good periodontal condition * Age 18-65 years, good general condition, no serious underlying disease, can tolerate multiple molding operations * Specific missing teeth with no serious soft or hard tissue lesions in the missing area, no bad biting habits, and no obvious tilting, shifting or loosening of the remaining teeth. Exclusion Criteria: * Tilting, shifting, loosening of remaining teeth * Non-specific tooth loss

Primary outcome measure(s)

  • Angular deviation — 3 year
    The digital data of the model is imported into the relevant software for implant matching, dentition segmentation, and processing of associated areas. In the reverse engineering software Geomagic Control X, the corresponding regions are aligned, the crown axis inclination of the implants is measured, and the angle between each crown axis and the implant axis is calculated, which represents the angular deviation.
  • Distance deviation — 3 year
    The digital data of the model is imported into the relevant software for implant matching, dentition segmentation, and processing of associated areas. In the reverse engineering software Geomagic Control X, the corresponding regions are aligned, the apex of each implant in the digital model is identified, and the distances between the implants are calculated, which represents the distance deviation.
