Immunological Features of Peri-Implant Soft Tissue After Healing Abutment Dislodgement: A Comparative Human Study

Healing abutment dislodgement is a common but often under-recognized complication in implant dentistry. This study demonstrates that loss of the soft tissue seal following abutment dislodgement leads to persistent and pronounced immune cell infiltration and long-lasting inflammatory responses Clinically, these findings highlight the importance of maintaining healing abutment stability and prompt restoration of the mucosal barrier to minimize inflammation and protect peri-implant tissue health. Improved awareness and evidence-based management of abutment dislodgement may help prevent peri-implant complications and optimize long-term treatment outcomes.
