Biological Complications: Preserving Peri-Implant Health

Biological complications, such as peri-implant mucositis and peri-implantitis, pose a significant threat to the long-term success of dental implants. Prevention and early intervention are crucial for managing these conditions.

Peri-implant Mucositis

Peri-implant mucositis is an inflammatory condition affecting the soft tissues surrounding an implant, characterized by redness, swelling, and bleeding on probing.

It is often caused by plaque accumulation and poor oral hygiene.

Effective plaque control measures, including meticulous brushing, flossing, and the use of antimicrobial mouth rinses, are essential for managing mucositis.

Professional cleaning and debridement of the implant surface may also be necessary.

Peri-implantitis

Peri-implantitis is a more advanced inflammatory condition that involves bone loss around the implant, in addition to the soft tissue inflammation seen in mucositis.

It can ultimately lead to implant failure if left untreated.

Treatment strategies for peri-implantitis include mechanical debridement, antimicrobial therapy, and surgical intervention to regenerate lost bone.

Guided bone regeneration (GBR) techniques may be employed to augment bone around the affected implant.

Regular monitoring of peri-implant tissues and bone levels at recall appointments is crucial for early detection and management of peri-implant diseases.
