Peri-implantitis is related to biofilm that adheres to the surface of implants and causes peri-implant chronic inflammation and bone destruction. Different surface treatments have been proposed to prevent biofilm formation. The objective of this systematic review was analyzing different types of antimicrobial coatings and identifying the most effective one(s) to control bacterial colonization over extended periods of analysis. Data, sources and study selection We performed a bibliographic search in Pubmed and Cochrane base of articles published after 2010 to answer, according to the PICO system, the following question: What is the most effective antibacterial surface coating for dental implants? Only papers including a minimum follow-up bacteria growth analysis for at least 48 h were selected. After selection, the studies were classified using the PRISMA system. A total of 40 studies were included. Conclusions Three main categories of coatings were identified: Antibacterial peptides, synthetic antimicrobial molecules (polymers, antibiotics, …), and metallic nanoparticles (silver). Antibacterial peptide coatings to modify dental implant surfaces have been the most studied and effective surface modification to control bacterial colonization over extended periods of incubation as they are highly potent, durable and biocompatible. However, more in vitro and pre-clinical studies are needed to assess their true potential as a technology for preventing peri-implant infections. his work was partly funded by MCIN/AEI/10.13039/501100011033 and the FSE+ through the project PREVENTITIS with reference PID2022–137496OB-I00 and the Departament de Recerca I Universitats de la Generalitat de Catalunya through the project 2021 SGR 00626.

Materials and methods: A total of 80 metal-ceramic crowns were fabricated using four different techniques: lost wax casting, milling, laser sintering, and milling of a presintered metal block. Marginal fit was measured at each manufacturing stage. Results: The porcelain firing stage improved marginal fit. CAD/CAM techniques resulted in better marginal fit than did conventional casting techniques at all manufacturing stages. Conclusion: CAD/CAM techniques improve marginal fit.

This article describes an updated clinical protocol to assess passive fit during the prosthesis fabrication process through the systematic use of tactile feel while tightening the retaining screws, the visual or radiographic evaluation when performing the 1-screw or Sheffield fit test, and the torque/time graph obtained during the placement of the implant- or abutment-retaining screws with a torque-controlled surgical motor.

Using a conventional protocol to fabricate IHS from casts of the initial situation or the wax-up can be challenging, time-consuming, and sometimes frustrating. A digital workflow makes this process quicker and more convenient. The IHS must be first designed with computer-aided design (CAD), then fabricated with computer-aided manufacture (CAM). Proprietary dental software is commonly used for the design process but needs to be purchased. Objective: To describe a step-by-step technique for designing an IHS for posterior relining with open-source software. Methods: This paper describes a straightforward procedure to design an IHS from a dental scan of the initial situation or a digital wax-up for an esthetic and functional temporary rehabilitation. Results: An IHS can be quickly designed using open-source software by copying an existing restoration or a conventional or digital wax-up. Then, the design can be 3D printed using a biocompatible resin. Conclusions: The clinician can use open-source software to design IHSs, which are then 3D printed using a biocompatible resin. Clinical relevance: The clinician can design IHSs from a dental scan of the initial situation or a wax-up using open-source software by following the step-by-step protocol outlined in this paper. The restoration can then be 3D printed using a biocompatible resin. Fri, 01 Jan 2021 00:00:00 GMT https://hdl.handle.net/20.500.12328/5400 2021-01-01T00:00:00Z
