| Abstract | ||
| Aim: Various methods were developed to enhance the bond between denture base and liners, for instance: mechanical (laser, sandblasting, sandpapering) and chemical (monomer, acid etching, plasma). This systematic review studies the methods of surface treatment used in literature and their effect on soft liner adhesion and registered on INPLASY : INPLASY2024120042. Materials and methods: Online search was performed in PubMed, EBSCOhost and Research Gate databases for free articles published between January 2010 and January 2025 to determine the studies concerning the subject. Further manual search was performed for studies mentioned in the reference list of the selected articles, in addition to articles discussed in literature reviews. Results: A total of 102 articles were found by the online search in addition to 20 articles obtained from the manual search. Only 49 articles were included in this review by following the inclusion criteria. This review revealed that twelve of 13 articles proved the effectiveness of laser in improving bonding strength, 10 articles showed that plasma caused a rise in bonding strength, 15 articles advocated that chemicals like monomer, primers and acids can increase the strength of adhesion, while one article claimed that silica coating followed by silanization did not improve the bond. Fourteen of 19 studies showed an improvement in bonding strength following sandblasting. Nine of 12 articles revealed the reduction in bonding strength following thermocycling. Conclusion: Laser, plasma, monomers, primers, acid etching and sometimes sandblasting are considered successful methods for enhancing the bond of soft liners, while thermocycling deteriorate it. | ||
