Implant-supported prostheses have to overcome a major difficulty presented by the morphology and esthetics of peri-implant tissues in the anterior sector. Diverse therapeutic techniques are used for managing the mucosa adjacent to the implant and the most noteworthy is immediate/deferred fixed provisionalization.
In vitro testing of strength and deformation of implant prosthetic abutments made from different materials (Titanium/PEEK/methacrylate).
Forty Sweden & Martina® implant prosthetic abutments (n=40) were divided into five groups: Group MP: methacrylate provisional abutments with machined titanium base; Group PP: Polyether ether ketone (PEEK) provisional abutments; Group TP: titanium provisional abutments; Group TAD: titanium anti-rotational definitive abutments; Group TRD: titanium rotational definitive abutments. Their mechanical behavior under static loading was analyzed. Samples were examined under a microscope to determine the type of fracture produced.
Definitive anti-rotational titanium abutments and definitive rotational titanium abutments achieved the best mean compression strength, while PEEK resin provisional abutments obtained the lowest. The group that showed the greatest elastic deformation was the group of titanium provisional abutments.
种植体支持的修复体必须克服前牙区种植体周围组织形态和美学方面带来的一个主要困难。多种治疗技术用于处理种植体周围的黏膜，其中最值得注意的是即刻/延期固定临时修复。
对由不同材料（钛/聚醚醚酮/甲基丙烯酸酯）制成的种植修复基台进行强度和变形的体外测试。
40个瑞典诺贝尔®种植修复基台（n = 40）分为五组：MP组：带加工钛基的甲基丙烯酸酯临时基台；PP组：聚醚醚酮（PEEK）临时基台；TP组：钛临时基台；TAD组：钛抗旋转最终基台；TRD组：钛旋转最终基台。分析它们在静态载荷下的力学行为。在显微镜下检查样本以确定产生的骨折类型。
最终抗旋转钛基台和最终旋转钛基台的平均抗压强度最佳，而PEEK树脂临时基台的抗压强度最低。弹性变形最大的组是钛临时基台组。
