"From a scientific and clinical perspective, which Straumann implant system demonstrates superior long-term success: the tapered design (BLT) or the cylindrical design (BLC)? And what factors influence the choice between them in clinical practice?"
In my opinion, BLT implants represent the natural evolution of modern implantology. Their improved morphology allows for insertion in both immediate and delayed implant placement protocols. Personally, I have no doubts when it comes to choosing them based on their macrodesign.
