Hyaluronic Acid vs I-PRF With Microneedling in Enhancing Peri-implant Soft Tissue

Despite the rising demand for esthetics and the prevailing use of dental implants in the recent era, the soft tissue remains a dilemma that affects patients' satisfaction and the implants' longevity in the oral environment, especially in the esthetic region of the maxilla. Various studies have been done to test the effectiveness of microneedling, hyaluronic acid, and i-PRF as alternative non-invasive or minimally invasive methods targeting tissue enhancement in the gingiva, and have proven that they have notable and desirable results. However, there is a lack in the literature regarding the use of these previously mentioned treatment options with regard to peri-implant soft tissue, and which of the delivered solutions offers superior results with reference to peri-implant mucosa in conjunction with microneedling.
