Introduction: The retention of an extraoral maxillofacial prosthesis poses a big challenge to the prosthodontist due to the complex and varied nature of facial defects. Several methods are available to enhance the retention of this prosthesis. This study was conducted to compare the efficacy of polysiloxane adhesives and n-butyl cyanoacrylate adhesives in providing retention for an extra-oral maxillofacial prosthesis. Materials and Methods: The samples were prepared by bonding silicone sheets with pigskin. These samples to be studied were divided into two groups of 20 samples each depending on the adhesive used for bonding the silicone sheets to the pigskin. Ten samples from each group were subjected to 180° and T-peel tests, respectively. Results: The results showed that the mean peel strength (PS) in the T peel test was higher for polysiloxane adhesive as compared to n-butyl cyanoacrylate adhesive, but the difference was not statistically significant. Whereas the mean PS in the 180° peel test was higher for n-butyl cyanoacrylate adhesive as compared to polysiloxane adhesive and the difference was statistically significant. Conclusion: The cyanoacrylate adhesives proved to be better in terms of PS.
