ABSTRACT Objectives Computer Assisted Implant Surgery (CAIS) with different technologies and modalities is becoming increasingly utilized in clinical practice. The aim of this White Paper was to synthesize evidence, reported experience, best practices regard clinically relevant outcomes static, dynamic, robotic CAIS. Materials Methods A review the literature compiled existing evidence from studies up November 2024, which later discussed synthesized into questions a panel international experts. Results There overwhelming for superiority CAIS accuracy implant placement some limited superior esthetic outcomes. At same time, related primary stability, survival rates, intra‐ postoperative complications, marginal bone loss, peri‐implant tissue health appear similar between guided non‐guided surgery, while efficiency poorly defined studied. importance execution comprehensive, prosthetically driven treatment plan not reflected most studies, focus mainly on assessment procedures rather than entire workflows. Such inherent limitations available research might conceal potential Conclusions Guided can achieve at least as good surgery. Studies that assess benefits part workflow, isolated procedures, could improve our understanding these technologies.

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