Dental implant success relies heavily on biomechanical stability, with abutment screws serving as critical connectors between implants and prosthetics. While modern implants boast >95% success rates, mechanical complications like screw loosening remain prevalent (19%–49% over 5–10 years)[5][11]. Thi

The Biomechanical ImperativeDental implants experience 1.2 million chewing cycles/year with peak loads reaching 450N in molar regions. The abutment screw design serves as the foundational stress distributor, with 68% of early failures originating from connection deficiencies. Recent studies reveal o
