Tensile Bond Strength between a Maxillofacial Silicone Elastomer and Biocompatible High Performance Polymer (BioHPP)

Aim: to test and evaluate the possible bond between BioHPP and one silicone elastomer for maxillofacial rehabilitation after using different types of retention. A total number of 120 test samples were made of BioHPP and the silicone elastomer. Both materials were bonded to each other with the help of different mechanical retentions and chemical agents. The ready test samples were used for two different tests/studies. Test 1 – а comparison of the bond strength between three adhesives: visio. lign, Mollosil adhesive and Universal Tray Adhesive. Test 2 – а comparison between three different types of bonding: mechanical retention, chemical adhesive and combined (mechanical and chemical). Results: from Test 1 – Mollosil has the highest mean values and from Test 2 – the combined type of retention has the highest mean values. Conclusion: BioHPP can be successfully bonded to maxillofacial silicone elastomer using adhesive containing Ethyl acetate and mechanical retention.
