Abstract

Debonded/detached denture teeth is a very common cause for denture failures. Chairside repairs using Polymethylmethacrylate (PMMA) is a technique sensitive and difficult procedure. An alternative adhesive that was quickly recognized was the Cyanoacrylate (CA). CA are solvent free adhesives that cure rapidly when pressed into a thin film between two surfaces. Apart from that, they have clinical applications in medicine, especially as tissue adhesives and sealing materials. Materials and methods: Specimens consisted of acrylic teeth bonded to acrylic denture base.
The specimens were divided into two groups; group I for testing bond strength using PMMA and group II for testing bond strength using CA. Results: The lowest mean MPa was seen in group 2 and the difference in MPa between this group and group 1 was significant. Conclusion: Even though CA appears to be the easier option, its` bond strength for teeth rebonding to denture base is less than that of PMMA.
