Abstract
Aims: The current study aimed to compare implant stability of dental implants covered with one of two - platelet rich fibrin preparation protocols namely Standard-Platelet Rich Fibrin and Advanced-Platelet Rich Fibrin) using radiofrequency assessment. Materials and methods: A total of ten male patients with an age range of 28-51 years participated in this split-mouth clinical study. The patients were divided into two groups based on the platelet rich fibrin (PRF) protocol to be used with dental implant insertion into positive control (S-PRF) and study group (A-PRF). Each patient represented the two groups in which he received 2 dental implants; ten implants for each group (a total of 20 dental implants) of standard length and diameter in the posterior mandibular extraction sites of ipsilateral or contralateral side. In the positive control group, the standard PRF protocol was to be used to prepare the PRF clot. In the study group, the advanced PRF protocol was to be used to prepare the PRF clot. Both PRF membranes were to be instilled inside the osteotomy bed during dental fixture installation. Following the installation of dental implants; radiofrequency assessment using Osstell Mentor Device immediately after insertion, four, eight; twelve weeks post-operative as secondary outcomes were conducted. Results: When comparing ISQ means of dental implants between both group protocols, the Friedman test values of ISQ means showed no statistically significant difference between them at the immediate day of surgery, four weeks, eight weeks and twelve weeks post-surgery yet showed increased levels of ISQ at end of the trial. Conclusions: Both S-PRF and A-PRF, similarly enhanced and maintained dental implant stability hence maintain osseointegration (synergistic effect) throughout the period of study and as disclosed by ISQ values. The use of PRF in its current forms seems to be an accepted minimally invasive approach with good clinical results.
