Passive fit of a long-span screw-retained implant prosthesis is an important criteria for the success of the restoration. This article describes a technique for fabricating a ceramometal implant fixed dental prosthesis (FDP) for a long-span partially edentulous situation by altering the conventional screw-retained design. The possibility of a passive fit is maximized by intraoral luting of the cast frame to milled abutments, and the potential framework distortion during fabrication is compensated to a major extent. Retrievability is ensured by screw retention of the prosthesis to the implants. Compared with conventional porcelain fused to metal screw-retained FDP, this prosthesis is relatively inexpensive to fabricate.
大跨度螺丝固位种植体修复体的被动适合性是修复成功的重要标准。本文介绍了一种通过改变传统螺丝固位设计来制作用于大跨度部分牙列缺损情况的金属烤瓷种植体固定义齿(FDP)的技术。通过将铸造支架口内粘接至研磨基台,使被动适合的可能性最大化,并且在很大程度上补偿了制作过程中潜在的支架变形。通过将修复体螺丝固位于种植体来确保可取出性。与传统的烤瓷熔附金属螺丝固位FDP相比,这种修复体的制作成本相对较低。
