In which dental scenario would debonding most likely occur?

• A. Use of resin bonded bridges
• B. Crown failure
• C. Immediate denture placement
• D. Orthodontic treatment

Answer: (A)

Debonding is a common consideration in dental scenarios involving adhesive materials, and it is most likely to occur with resin bonded bridges. These bridges utilize adhesive mechanisms to bond the prosthetic restoration to the adjacent teeth. If the bond between the resin and the tooth structure is compromised—due to factors like moisture contamination during placement, improper surface preparation, or forces exerted during function—debonding can occur. In contrast, crown failure is not solely dependent on adhesive properties; it can result from issues related to the crown material, fit, occlusion, or underlying tooth health. Immediate denture placement involves different principles, primarily focusing on stability and support from the residual ridge rather than bonding to natural teeth. Orthodontic treatment, while it does involve bonding brackets to teeth, typically uses materials designed to withstand forces without debonding, and any bond failure in these cases tends to either be sporadic or related to mechanical factors rather than inherent to the bonding process itself. Therefore, resin bonded bridges present the highest risk for debonding due to the reliance on adhesive bonding for functional and aesthetic integrity.
