Abutment on Titanium-Base Hybrid Implant: A Literature Review

Abstract

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.

Clinical performance of single implant prostheses restored using titanium base abutments: A systematic review and meta‐analysis

“…Titanium base abutments classified as CAD/CAM stock abutments offer the opportunity to select the height of the transmucosal segment so that the abutment shoulder with the corresponding restoration and cement margin is distant from the marginal bone, while allowing an emergence profile that facilitates an aesthetic outcome and cleanability. Above the abutment shoulder, the selected restorative material, such as zirconia, lithium disilicate or polymer‐infiltrated ceramics, can be customized based on the desired clinical emergence profile (de Melo Moreno et al, 2022). When comparing differing materials around the emergence profile of an implant‐abutment prosthesis complex, zirconia has reduced plaque retention and demonstrates a better quality of soft tissue attachment when used as an abutment material (Enkling et al, 2022).…”

Clinical performance of implant-supported single hybrid abutment crown restoration: A systematic review and meta-analysis

“…It is characterized by a prefabricated, low-profile Ti base with retention features for extraorally cemented ceramic suprastructures. This design combines the aesthetic superiority of ceramic materials with the excellent mechanical stability provided by a metallic connection [7,10]. The titanium-titanium implant-abutment interface provided by a Ti base may avoid the potential risk of internal implant connection damage due to titanium-zirconia wear [11].…”
