Peri-implant tissues comprise of soft and hard structures-mucosa and alveolar bone-that surround a functional dental implant. Unlike the periodontium of natural teeth, this tissue lacks a periodontal ligament and features collagen fibers aligned parallel to the implant surface, creating a less vascularized "biologic seal."In health, the mucosa remains firm and pink, characterized by the absence of bleeding on probing and no radiographic bone loss beyond initial physiological remodeling.Peri-implant diseases are plaque-induced inflammatory conditions. Peri-implant mucositis is a reversible...
