Purpose: The purpose of this study was to compare the retention of the two denture adhesives with a silicone edentulous model and a resin denture base in vitro study.
Material and methods: The experimental groups were used two denture adhesives and classified into 5 subgroups each. Subgroups were divided by the number of times the saliva sprayed. The control group was used synthetic saliva only. Dislodging tensile strengths were applied to the resin denture base using Instron in 3 directions : vertical, lateral, and anterior-posterior.
Results: The retention of two denture adhesives was increased significantly than saliva alone (P < .05). In each denture adhesives, the retention of saliva sprayed first was decreased than denture adhesive alone, but it didn’t have significant differences. Whenever saliva sprayed repeated, the retention was decreased significantly than saliva sprayed first (P < .05). In each denture adhesives, vertical retentive force was highest than lateral and anterior-posterior retentive forces, and anterior-posterior retentive force was higher than lateral retentive force. This results were significantly different (P < .05). Significant differences of the retentive ability among two denture adhesives were not observed.
Conclusion: From the results, use of the denture adhesives resulted in improved retentive ability of denture. Especially retentive force was highest in vertical direction.
