3D Analysis of Peri-implant Soft Tissue with Two Different Connection Types

Thirty eight patients were enrolled in the study and received randomly allocated implants with conical and butt-joint implant-abutment connection type. A standard healing abutment was placed after 6 months for two weeks. The definitive screw retained crowns were manufactured in a digital workflow. The soft tissue profile was digitized using IOS on following stages: pre-op, post-op: immediately, two, 7 and 14 days, pre-exposure, immediately after exposure, two weeks after exposure (pre-delivery), immediately after crown delivery, 6 and 12 months post-op.
