An increase in the use of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) technologies challenges the conventional prosthetic fabrication procedures that are practical and centered on a digital workflow for the patient, especially for dental implants. Increasing workflow of digital restoration work, considering computer-used CAM for restoration technology systems and also fast/CAM for building restoration technology; fast/CAD, also known as abut-Base, has increased interest. Studies on adaptation of different restorative materials, on titanium (Ti)-base abutments, traction, and transformed cycling have become relevant. The objective of this work was to research, through literature studies, on restoration-type abutments. A total of 24 articles were found after searching the following terms in PubMed/Medline, Scopus, and Embase databases: "ti-base AND abutment." Twenty-one manuscripts selected from the inclusion and exclusion criteria. After an analysis of these articles, it was concluded that the Ti-base abutment and components from the same manufacturer as the Implant should be used preferably; milled monolithic crowns designed to adapt to the Ti-base the hybrid abutment-crown assembly does not affect torque maintenance after thermal aging; the saliva and cleaning protocol of the Ti-base bonding surfaces can influence the operations of the Ti-base crowns; Ti-base and Crown surface treatment is recommended for better applicability and stability results, and the superiority of resin-based cements compared with other types of cements.
计算机辅助设计(CAD)和计算机辅助制造(CAM)技术使用的增加,对以患者数字工作流程为核心的传统假体制造程序提出了挑战,尤其是在牙种植体方面。考虑到用于修复技术系统的计算机辅助CAM以及用于构建修复技术的快速/CAM,数字修复工作的工作流程不断增加;快速/CAD,也称为基台-基座,引起了更多关注。关于不同修复材料在钛(Ti)基台上的适应性、牵引力和循环变化的研究变得至关重要。这项工作的目的是通过文献研究来探讨修复型基台。在PubMed/Medline、Scopus和Embase数据库中搜索以下关键词后,共找到24篇文章:“钛基与基台”。从纳入和排除标准中筛选出21篇手稿。对这些文章进行分析后得出结论:最好使用与种植体同一制造商生产的钛基基台及其组件;设计用于适配钛基的铣削整体冠,混合基台-冠组件在热老化后不会影响扭矩维持;钛基粘结表面的唾液和清洁方案会影响钛基冠的操作;建议对钛基和冠表面进行处理,以获得更好的适用性和稳定性结果,以及树脂基粘结剂相对于其他类型粘结剂的优越性。
