This article aims to help clinicians understand the advantages and disadvantages of a myriad of ceramic materials and technique options available in dentistry today. The microstructural components, materials’ properties, indications, and names of products are discussed to help clarify their use. Key topics will include ceramics, particle-filled glasses, polycrystalline ceramics, CAD⁄CAM, and adhesive cementation.
Universal adhesive systems have the potential to significantly simplify and expedite adhesive protocols and may indeed represent the next evolution in adhesive dentistry. But what defines a universal system, and are all these new systems truly “universal” and everything they are claimed to be? This article examines the origin, chemistry, strengths, weaknesses, and clinical relevance of this new genre of dental adhesives.
In this case report, a resin-modified glass-ionomer (RMGI) liner was utilized in deep restorations on premolars that had old, existing amalgam restorations and were experiencing microleakage and sensitivity problems. The materials and technique used allowed for conservative treatment while delivering an esthetic and functionally pleasing result.
Research regarding the wear properties of zirconia has shown that it is more friendly to opposing enamel than veneering porcelain. This case report documents the rationale and procedure for bonding a veneered zirconia restoration. The case demonstrates that, when properly designed, veneered zirconia restorations offer acceptable esthetic and mechanical properties for anterior fixed partial dentures.
This report documents treatment and repair of three carious teeth that were restored with a new dental repair material that features the characteristics of both resin-modified glass-ionomer restorative cement (RMGI) and resin-based composite (RBC). The restorative products presented are reported by the manufacturer to be the first bioactive dental materials with an ionic resin matrix, a shock-absorbing resin component, and bioactive fillers that mimic the physical and chemical properties of natural teeth.
The progression of provisional materials to bis-acrylics has lead to such improvements as easier handling, improved compressive and tensile strength, less water sorption, and less shrinkage. This review of current products affirms that the choices of provisional materials available for the dental professional today are quite extensive and have advanced the quality of interim restorations.
