Assessing the Effects of L-PRF on the Peri-implant Soft and Hard Tissue Parameters in Immediate Implants: A Randomised Controlled Trial

Background and aim: Platelet-rich fibrin is a healing biomaterial with greater potential for enhancing tissue and osseous healing and regeneration without inflammatory reactions and can be used alone or in combination with bone grafts to promote blood coagulation bone maturation and growth. Although the use of platelet-rich plasma in dentistry, enhancing peri-implant healing with immediate implants placement is not well authenticated. The main aim of this study is to assess the effect of Leukocyte-and Platelet-Rich Fibrin (L-PRF) on the peri-implant soft and hard tissue parameters in immediate implants.
Materials and methods: The split-mouth, randomized controlled trial on 10 systematically healthy subjects with adequate and maintainable oral hygiene. Subjects were enrolled, and sites were specified. On one site, atraumatic extraction was followed by immediate implant placement, while at another site, atraumatic extraction was done, followed by immediate implant placement with L-PRF application. Patients were recalled after 1, 3, and 6 months to evaluate various parameters, including tissue biotype, whether thick or thin, radiographic radiolucency (present or absent), modified plaque index, modified sulcus bleeding index, probing depth. The data was compiled and evaluated with an ANOVA test with a significant p-value of 0.05.
Results: Statistically significant values were observed in all the parameters evaluated after the surgical procedure at 1, 3, and 6-month intervals with immediate implant placement along with Leukocyte-and Platelet-Rich Fibrin (L-PRF) membrane in extraction sockets.
Conclusion: Within the study's limitation, it can be concluded that L-PRF can be used as a therapeutic adjuvant in clinical conditions of one-stage single tooth implant placements.
