This article presents a technique for fabricating a passively fitting implant-supported screw-retained complete-arch interim restoration with resistance to early fracture. Two gypsum casts were obtained from an implant impression using the splinting technique. The complete-arch interim restoration with abutment access holes, which was reinforced with a glass fiber splint, was fabricated on one cast and connected to restorative abutments on the other cast extraorally to eliminate stresses from the polymerization shrinkage of resin.
本文介绍了一种制造被动贴合种植体支持的螺丝固位全弓临时修复体的技术，该技术具有抵抗早期断裂的能力。使用夹板技术从种植体印模中获得了两个石膏模型。在一个模型上制作带有基台孔的全弓临时修复体，并使用玻璃纤维夹板进行加固，然后在另一个模型上将其与修复基台连接起来，以消除树脂聚合收缩产生的应力。
