Summary

The project is a prospective, randomized, controlled study. The material BioHPP (High Performance Polymer) is compared with the gold-standard abutment materials titanium and zirconia in terms of peri-implant soft tissue healing.

Detailed description

A total of 60 participants are divided into three groups of 20 persons each. One group receives BioHPP abutments, while the two control groups receive titanium or zirconia abutments. The patients are provided with closed healing dental implants. After 3 months, following implant exposure and optical impression, the implants are restored with individual abutments. Follow-up appointments are scheduled at 3, 6, 12, 24, and 36 months after implantation. During these visits, implant healing is assessed based on clinical parameters such as probing depth, plaque index, mean bone level, and bleeding on probing.

Conditions
