The present study was conducted to assess stress distribution around dental implants based on the all-on-four treatment concept. The finite element analysis (FEA) models comprised cancellous bone covered with cortical bone. Four dental implants were placed in two different designs. In model 1, the four implants were placed parallel to each other, whereas, in model 2, the all-on-four concept was followed. The vertical and lateral loads of various values were applied, and stress was evaluated. In model 2, the least stress was observed in both lateral and vertical loading in the peri-implant region. The all-on-four concept proved to be beneficial in reducing the stress around dental implants, thereby reducing the treatment cost.
本研究旨在基于全口四颗种植体治疗理念评估牙种植体周围的应力分布。有限元分析（FEA）模型包括覆盖有皮质骨的松质骨。以两种不同设计植入四颗牙种植体。在模型1中，四颗种植体彼此平行放置，而在模型2中，遵循全口四颗种植体理念。施加不同值的垂直和侧向载荷，并评估应力。在模型2中，种植体周围区域在侧向和垂直载荷下均观察到最小应力。全口四颗种植体理念被证明有利于减少牙种植体周围的应力，从而降低治疗成本。
