Purpose: Prefabricated dowels have become popular, and a wide variety of systems are available. Recently, in response to a need for tooth‐colored dowels, several nonmetallic dowels such as carbon‐fiber epoxy resin, zirconia, glass fiber‐reinforced epoxy resin, and ultra‐high polyethelene fiber‐reinforced dowels are available. With a plethora of different materials and systems currently available for use, an overview of the scientific literature on nonmetallic dowels is indicated. This article reviews the current literature dealing with the compositions, properties, and laboratory and clinical test results of nonmetallic prefabricated dowels. Methods: A comprehensive review of the literature was completed seeking evidence for the treatment of teeth with nonmetallic prefabricated dowels. A search of English language peer‐reviewed literature was undertaken using MEDLINE and PubMed with a focus on clinical research articles published between 1996 and 2007. A hand search of relevant dental journals was also completed. Results: The literature demonstrates that in vitro investigations demonstrated favorable physical and mechanical properties of these dowels; however, clinically, there has been a wide range of reported failure percentages. Conclusion: Since there is considerable variation in reported failure percentages, longer‐term studies are needed that present data regarding all types of complications that have been identified in the literature.
