Summary

This study aims to evaluate the clinical effectiveness of biomimetic abutments in implant restoration.

Detailed description

The biomimetic healing abutments were placed during the second-stage surgery, and the biomimetic prosthetic abutments were used to complete the implant restoration. To assess soft tissues, digital models were collected in STL files at five time points: before the second-stage surgery, before the implant impression, immediately after restoration, six months after restoration, and 12 months after restoration. These models were analyzed using 3D software for model matching and measurement based on CBCT, focusing on the changes on soft tissue height, width, and volume. Hard tissue evaluation was conducted through periapical radiographs taken at three time points: immediately after restoration, six months after restoration, and 12 months after restoration. Additionally, general clinical conditions were assessed at the same three time points, evaluating parameters such as food impaction, plaque index, and gingival index.
