11/7/2023 0 Comments Cerec tessera blocks![]() ![]() Just like silicate ceramics, they differ greatly in their optical and mechanical properties. Users should be aware of the indications and limitations of these different ceramics. After numerous improvements, we can now distinguish between five generations of modern zirconia restoratives. As a viable alternative to metal-based restorations, featuring a high esthetic potential and excellent biocompatibility, these ceramics have become very popular and have replaced metals in a variety of indications. ![]() In the 1990s, the first oxide ceramic crowns and bridges were made, thanks to new computer-aided grinding and milling systems and polycrystalline crystals reinforced with 5.35% by weight of yttrium oxide. ![]() While in the past almost exclusively manual techniques, such as layering or pressing, were used to produce ceramic restorations, computer-aided design and computer-aided manufacturing (CAD/CAM) technology now help us to process completely new materials, which are unfit for manual processing. Because of these properties and the patients' demand for materials that are as lifelike as possible, ceramics are widely used in present-day dentistry. Dental ceramics are known for their high esthetics and biocompatibility. The use of digitally generated data sets, computer-aided design, and numerical control (NC) technology for processing silicate and oxide ceramics allows us to work with new, industrially prefabricated and almost defect-free restorative materials. Indirect restorations can now be made in dental practices (chairside), laboratories, or even production centers. The advent of computerized technologies in restorative dentistry has led to an enormous change for dentists and dental technicians. It impacts not only social life but also the way dentistry is performed. The rehabilitation with the ALD blocks resulted in an aesthetically pleasing, functional outcome that improved overall treatment time and increased patient and practitioner satisfaction, which remained stable over a one-year follow-up period.Įverybody is talking about digitalization today. The monolithic restorations were placed adhesively. ![]() In the present case report, restorations were indicated for seven posterior teeth, which were prepared, scanned, designed with CEREC-Primescan SW 5.1.3, and fabricated with MCX5. Although more evidence from long-term clinical studies is needed to verify the clinical performance and manufacturer recommendations regarding indication, preparation and cementation must be followed very strictly. New treatment indication options for lithium disilicate ceramics will expand. The shorter processing time combined with high flexural strength will optimize the chairside workflow. The newly introduced ALD ceramic for the “Chairside Economical Restoration of Esthetic Ceramics”/“CEramic REConstruction” (CEREC) system produces an esthetically pleasing and clinically excellent restoration. Time efficiency, predictability, and economically interesting treatment options are of great importance in current dentistry and can be well implemented in CAD/CAM dentistry. The remarkable speed sintering time of approx. According to the manufacturer, the material provides a biaxial strength measured at >700 MPa and improved optical properties. It is reinforced with virgilite crystals in managing esthetic demand of patient besides having a high flexural strength. This case report highlights the minimally invasive rehabilitation with a new advanced lithium disilicate (ALD) ceramic block. Advancements in materials science and bonding protocols as well as new manufacturing methods foster the development of novel ceramic materials to meet the increased demands for highly aesthetic, biocompatible, and long-lasting restorations in fixed prosthodontics. ![]()
