Titanium Particles Within Mucosa During Non-Surgical Implant Debridement, Holvin Louie

Loma Linda University Electronic Theses, Dissertations & Projects

Titanium implants affected by peri-implantitis lesions are often treated non-surgically with various instruments, which may produce titanium particles that can become lodged within the peri-implant mucosa. Thus, a foreign body reaction may ensue. The aim is to assess the embedment of titanium particles into soft tissues from titanium implants via a stainless-steel ultrasonic scaler (SSU) versus a titanium hand scaler (TH). Sand-blasted, large grit, acid-etched surface-treated titanium implants were implanted into pig legs after creating peri-implantitis defects. Each implant was subjected to only one instrument type. Sequential strokes were conducted followed by thorough irrigation with sterile water. Soft tissue curettage …
