What is the best cement to enhance retention for a short crown?

• A. Ceramic cement
• B. Glass ionomer cement
• C. Resin cement
• D. Hybrid cement

Answer: (C)

Resin cement is the best choice for enhancing retention for a short crown due to its superior bonding capabilities. It is characterized by a strong adhesive quality that allows it to effectively bond to both tooth structure and the crown material, providing a stable and durable hold. This is particularly important for short crowns, which may have limited surface area for retention. Resin cements typically involve a chemical bonding process that enhances the union between the crown and the tooth, making them ideal for situations where traditional mechanical retention is inadequate. The low viscosity of resin cements allows them to flow into micro-retentive features, enhancing the overall retention of the crown. In contrast, ceramic cements are designed primarily for bonding ceramic restorations but may not provide the same level of retention as resin cements with short crowns. Glass ionomer cement is beneficial for its fluoride-releasing properties and ease of use but tends to have lower bond strength compared to resin cements. Hybrid cements, while they combine features of both resin and glass ionomer cements, may not match the retention strength that pure resin cements offer. Therefore, resin cement stands out as the optimal choice for fixing short crowns effectively.
