What is the best type of cement for short clinical crowns?

• A. resin bonded
• B. polycarboxylate
• C. zinc phosphate
• D. glass ionomer

Answer: (A)

Resin bonded cement is considered the best choice for short clinical crowns primarily due to its superior adhesive properties. This type of cement provides strong retention and bonds effectively to both the tooth structure and the material of the crown. Resin cements are specifically formulated to optimize the bond strength by utilizing adhesive resins that can chemically and micromechanically bond to the tooth surface, which is particularly beneficial in cases where the crown length is limited. In situations involving short clinical crowns, achieving a secure bond is essential, as the retention potential using traditional cements might not be adequate. The strong bond provided by resin bonded cements minimizes the risk of dislodgment and helps in distributing occlusal forces more evenly, thus enhancing the longevity of the restoration. Other types of cements, while useful in specific scenarios, do not match the performance of resin bonded cements for this particular application. Polycarboxylate cement, zinc phosphate cement, and glass ionomer cement can all be effective under certain conditions but generally do not offer the same level of adhesion and retention needed for short crowns where the surface area for bonding may be limited.
