采用三维有限元分析方法，在轴向（AX）、颊舌向（BL）或近远中（MD）载荷下，对部分无牙下颌骨采用三种治疗设计，评估钛种植体周围骨的应力。对于这些载荷中的每一种，在由两个种植体支撑的悬臂式假体模型中计算最高应力（M2）。两颗种植体固定义齿模型（M3）的应力较小，三颗种植体支持三个连接冠模型（M1）的应力最低。当对M3施加BL载荷时，皮质骨应力较高，与相同载荷下M2的计算值相当。当对M3施加AX或MD载荷时，皮质骨应力较低，与M1在这些载荷下的结果相似。
The three-dimensional finite element analysis method was used to assess stress in bone around titanium implants using three treatment designs for a partially edentulous mandible, under axial (AX), buccolingual (BL), or mesiodistal (MD) loads. For each of these loads, highest stress was calculated in the model with a cantilever prosthesis supported by two implants (M2). Less stress was found in the model with a conventional fixed partial denture on two implants (M3), and lowest stress was calculated in the model with three connected crowns supported by three implants (M1). When BL load was applied to M3, cortical bone stress was high, comparable to that calculated for M2 under the same load. When AX or MD load was applied to M3, the cortical bone stress was low, similar to that found in M1 under each of these loads.
