Extended Platelet-Rich Fibrin as a Membrane for Lateral Window Sinus Lifts: A Case Series.

Introduction: Platelet-rich fibrin (PRF) is being increasingly utilized in surgical procedures due to various improvements in clinical outcomes. More recently, a heating process to denature albumin in the platelet poor plasma (PPP) layer has been shown to extend the resorption time of PRF from a typical 2-week period to 4-6 months. Because of its > 4 month resorption properties, extended PRF (e-PRF) membranes have been used in dentistry as an alternative to collagen membranes in alveolar ridge preservations, ridge augmentations, soft tissue grafting, and as a barrier membrane in lateral sinus grafting procedures.

Autogenous platelet concentrates for treatment of intrabony defects-A systematic review with meta-analysis.

To provide an overview of the use of autogenous platelet concentrates (APCs) in periodontal regeneration and to conduct a systematic review (SR) of the treatment outcomes of periodontal intrabony defects by using platelet-rich fibrin (PRF) compared with other commonly utilized modalities. The eligibility criteria comprised randomized controlled trials (RCTs) comparing the clinical outcomes of PRF with that of other modalities. Studies were classified into 21 categories and into five different groups as follows: Group I (1) open flap debridement (OFD) alone versus OFD/PRF, (2) OFD versus Titanium-PRF (T-PRF) Group II, (3) Comparative PRF protocols (PRF vs.

Periodontal regeneration using platelet-rich fibrin. Furcation defects: A systematic review with meta-analysis.

The objective of the study was to compare the treatment outcomes of periodontal furcation defects by using platelet-rich fibrin (PRF) with other commonly utilized modalities. The eligibility criteria comprised randomized controlled trials (RCTs) comparing the clinical outcomes of PRF with those of other modalities for the treatment of furcation defects. Studies were classified into 11 categories in 3 different groups as follows: Group I (addition of PRF): (1) open flap debridement (OFD) alone versus OFD/PRF, (2) OFD/bone graft (OFD/BG) versus OFD/BG/PRF; Group II (comparative studies to PRF): (3) OFD/BG versus OFD/PRF, (4) OFD/collagen membrane versus OFD/PRF, (5) OFD/PRP versus OFD/PRF, (6) OFD/rhBMP2 versus OFD/PRF; and Group III (addition of biomaterial/biomolecule to PRF): OFD/PRF versus … (7) OFD/PRF/BG, (8) OFD/PRF/amniotic membrane (AM), (9) OFD/PRF/metformin, (10) OFD/PRF/bisphosphonates, (11) OFD/PRF/statins.

A transcrestal sinus floor elevation strategy based on a haptic robot system: An in vitro study.

Objectives: To reveal the force profiles recorded by haptic autonomous robotic force feedback during the transcrestal sinus floor elevation (TSFE) process, providing a reference for the surgery strategy during TSFE.

Materials And Methods: A total of 42 maxillary sinus models with different angles of the sinus floor (30°, 40°, 50°, 60°, 70°, 80°, and 90°, compared to vertical plane) were 3D printed. Implant site preparation was performed using a robotic system, and the total force (Ft) and axial force along the drill (Fz) during the surgery were recorded by the haptic robotic arm.
