Abstract
Background: The serviceability of a relined prosthesis is adversely affected by repeated de-bonding of the soft liner from the denture base resin. Aim: to evaluate the bond strength between the denture bases and commercially available soft liners when using different surface treatments. Material and method: An extensive systematic review was conducted across databases such as PubMed, Google Scholar, and Scopus, involving all articles from January 2011 to June 2024. The 110 records from the research search were screened, resulting in the exclusion of 30 duplicates and 38 papers that did not meet the inclusion criteria of the current study. Twelve were excluded because they were not downloadable for analysis. Thirty-one articles meeting the requirements were identified for full review. Result: Using database searches, 110 articles were first found. Of these, 31 satisfied the requirements for qualitative analysis. Nine out of twelve articles reported that laser preparation of denture base resins improved their adhesion to soft liners. Six studies concluded. According to six out of seven studies, monomer treatment strengthened the liner-resin connection in the liner. According to six out of seven trials, monomer treatment strengthened the liner-resin connection. According to four investigations, binding strength was also enhanced by the acidetching procedure. Conclusions: The tensile test has been frequently used in assessing the adhesive bond strength between the denture base and soft liner. Several types of surface pretreatments, including laser, air abrasion, silica coating, acid etching, and monomer treatment, have been developed to enhance the adhesion between soft liners and denture base resins.
