Comparison between Injectable Platelet Rich Fibrin with Collagen Carrier and Carrier and β-Tricalcium Phosphate in Lateral Maxillary Sinus Lift with Simultaneous Implant Placement

Abstract

Objective: This study aimed to compare injectable platelet-rich fibrin (I-PRF) with a collagen carrier and b-tricalcium phosphate (b-TCP)  for maxillary sinus floor augmentation (MSFA) with simultaneous implant placement.

Patients and methods: Fourteen patients with missed maxillary posterior teeth and 3e5 mm residual bone height were selected to  perform lateral MSFA with simultaneous implant placement. A total of 18 sites (implants) in 13 patients were qualified for analysis, 10  sites with I-PRF and collagen carrier (group I) and eight sites with b-TCP (group II). Six months later, implant stability was recorded, and  all sites were analyzed using cone-beam computed tomography for measuring apical bone height, vertical bone gain, and final bone  height.

Results: After 6 months 100 % implant success was observed, the mean of implant stability quotient was 75.90 ± 2.56 and 76.13 ±  2.23 for group I and II, respectively (P ¼ 0.300), the median of apical bone height was 0 (0e4.5) for group I and 4.33 (0.5e9.6) for group II  (P ¼ 0.004), the mean of vertical bone gain for group I was 6.52 ± 1.71 mm and 9.81 ± 2.47 mm for group II (P ¼ 0.004), the mean of final  bone height for group I was 10.96 ± 1.50 mm, while group II was 14.08 ± 2.32 mm (P ¼ 0.003).

Conclusions: I-PRF with collagen carrier is  an economical biomaterial that preserves the created subantral space with adequate new bone formation congruous to implant apexes.  So, lateral MSFA using I-PRF and collagen carrier with simultaneous implant placement could be a simple, reliable, and predictable  surgery with a high success rate that could be comparable to using b-TCP.
