Current Trends of Hyaluronic Acid Use as a Therapeutic Strategy in Peri-Implantitis: A Scoping Review

Peri-implantitis is marked by ongoing bone loss and soft tissue inflammation surrounding dental implants. Due to its ability to intensify tissue healing and its compatibility with the body, hyaluronic acid (HA) has appeared as a viable biomaterial for managing this oral condition. The goal of this scoping review is to examine current trends and future directions for refining HA-based interventions as an adjuvant peri-implant therapy over the past decade. Using the PRISMA-ScR guidelines, a review of the literature for the past 10 years was conducted. Articles related to HA’s anti-inflammatory, antimicrobial, regenerative mechanisms were taken into consideration to underline both achievements and research related to peri-implantitis treatment management. A total of 105 articles were found, and finally, five clinical studies were included. Despite encouraging results that showed good efficacy of HA use as an adjuvant and/or preventive therapeutic agent for peri-implantitis treatment, a larger number of randomized controlled trials and standardized protocols are needed to confirm HA’s therapeutic efficacy and establish its place in routine clinical practice.
