Marginal Bone Level Changes in Implant‐Supported Fixed Prostheses in a Retrospective Study: A Multifactorial Analysis

Marginal bone level around implant-supported prostheses was influenced by the interplay of multiple factors consisting of deep probing depth, absence of keratinized mucosa, inadequate transmucosal height, microgap configuration, and history of periodontitis. These findings emphasized the need for comprehensive peri-implant assessment, which included monitoring probing depths and soft tissue quality. Additionally, it was crucial to ensure that prostheses were well-designed and had the appropriate transmucosal height. Patients with a history of periodontitis were advised to follow a strict maintenance program. Further prospective studies are needed to confirm the causality for ongoing investigation into the specific aspects and mechanisms involved.
