Does Implant-Abutment Interface affect Marginal Bone Levels around Implants?

Marginal bone loss around dental implants with various types of implant-abutment connection in the same patient

Introduction. One of the criteria of implant therapy success is marginal bone loss. The objective of the study was to assess the correlation between peri-implant marginal bone loss and implant-abutment connection systems used in the same patient, as well as other specific characteristics of implant treatment. The initial research hypothesis assumed that there was no difference in marginal bone ...

Comparisons of maximum deformation and failure forces at the implant–abutment interface of titanium implants between titanium-alloy and zirconia abutments with two levels of marginal bone loss

BACKGROUND Zirconia materials are known for their optimal aesthetics, but they are brittle, and concerns remain about whether their mechanical properties are sufficient for withstanding the forces exerted in the oral cavity. Therefore, this study compared the maximum deformation and failure forces of titanium implants between titanium-alloy and zirconia abutments under oblique compressive force...

Analysis of implant/abutment marginal fitting

The success rate of osseointegrated implants is reported to be above 90%. Despite of the knowledge of the mechanisms of osseointegration, some faults still occur at implants systems. Recent researches assign those faults mainly to patient’s prosthetic rehabilitation. The misfit at abutment-implant interface and the missing of a passive adaptation between the prosthesis and the abutment can lead...

Evaluation of Marginal Bone Level around Platform - Switched Implants

Purpose: The long-term success of an implant depends on the stability of bone support for the implant. Most crestal bone loss occurs in the first year of implant placement. Platform-switching is an approach which can be clinically applied to preserve the crestal bone. The concept of ‘platform switching’ refers to the use of a smaller-diameter abutment on a larger-diameter implant collar. The pu...
