ObjectivesThe objective of this study is to investigate the outcomes of clinically relevant laboratory studies regarding the cementation of implant‐supported restorations over ti‐bases.Materials and MethodsThe present study has been conducted according to PRISMA statement. An electronic search was performed, including publications up to March 2024, to identify studies investigating the parameters affecting the cementation between ti‐bases and CAD/CAM prostheses. An assessment of the internal validity was performed, using a custom‐made risk of bias tool (QUIN).ResultsFrom the included studies, 40.1% were reported on luting systems, 25% on ti‐base surface treatment, 25% on restoration surface, 21.8% on restoration material, and 18.7% on ti‐base height. The majority of the included studies were associated with a medium risk of bias. In the absence of micro‐retentive features, air‐abrasion of ti‐bases with a minimum height of 3.5 mm can be beneficial for restoration's retention. The bonding performance can vary not only between different bonding systems but also for different applications within the same system, based on a restoration's material and surface treatment as well as on ti‐base height and surface treatment.ConclusionsThe height of the ti‐base seems to be the prevailing factor as it constitutes the prerequisite for other modifications of the bonding surfaces to have an advantageous effect. Since the parameters that can affect bonding performance between ti‐base and restoration can interact with each other, it is important for the clinician to focus on verified bonding protocols.

CAD/CAM 制造的假体在钛基座上的粘接的体外评估。系统评价


目的本研究的目的是调查关于种植体支撑修复体在 ti 基座上的粘接的临床相关实验室研究的结果。材料和方法本研究是根据 PRISMA 声明进行的。进行了电子检索，包括截至 2024 年 3 月的出版物，以确定调查影响钛基和 CAD/CAM 修复体之间粘接的参数的研究。使用定制的偏倚风险工具 （QUIN） 对内部效度进行评估。结果从纳入的研究中，40.1% 的报告是粘接系统，25% 是钛基表面处理，25% 是修复表面，21.8% 是修复材料，18.7% 是钛基高度。大多数纳入的研究与中等偏倚风险相关。在没有微固位特征的情况下，最小高度为 3.5 mm 的钛基的空气磨损有利于修复体的固位。粘合性能不仅在不同的粘合系统之间有所不同，而且在同一系统内的不同应用中也会有所不同，具体取决于修复体的材料和表面处理以及钛基高度和表面处理。结论钛基的高度似乎是主要因素，因为它构成了粘合表面的其他改性产生有利效果的先决条件。由于可能影响 ti-base 和修复体之间粘合性能的参数可以相互影响，因此临床医生必须专注于经过验证的粘合方案。
