Restorative considerations are critical to the long-term success of fixed implant-supported prostheses, especially in the posterior quadrants of the partially edentulous patient. The parafunctional habit of bruxism must be identified and addressed. The restoration should dictate implant placement. Control of forces directed upon the prosthesis and implants is critical to long-term success. Anatomic limitations to implant placement and surgical procedures to correct these deficiencies must be considered for their impact on the prosthetic restoration. Nonaxial forces or bending moments should be minimized by the use of an adequate number, position and alignment of implants; by control of the occlusion; and by design of the prosthesis. The patient must understand the risks, limitations, costs and time commitments of implant restorations prior to treatment.
修复方面的考量对于固定种植支持式修复体的长期成功至关重要，尤其是在部分牙列缺损患者的后牙区。必须识别并处理磨牙症这种副功能习惯。修复体应决定种植体的植入位置。控制作用于修复体和种植体上的力量对于长期成功至关重要。必须考虑种植体植入的解剖学限制以及纠正这些缺陷的外科手术对修复体的影响。应通过使用足够数量、合适位置和排列的种植体；控制咬合；以及设计修复体来将非轴向力或弯矩降至最低。在治疗前，患者必须了解种植修复的风险、限制、成本和时间投入。
