Abstract:
Biomechanical implant design influences peri-implant stress distribution and long-term bone maintenance despite modern advances. Therefore, it is of interest to compare traditional threaded, tapered and platform-switched implants in 75 patients receiving 90 implants across varying bone densities and arch locations over 3 years. Platform-switched implants showed 34% lower crestal stress (p<0.001) versus conventional designs via FEA validation. Marginal bone loss measured 0.42±0.18 mm for platform-switched versus higher losses in others (p<0.001), with equivalent survival rates. Platform-switching provides superior biomechanical protection and bone preservation, establishing evidence-based design superiority for clinical practice.
