Abstract: Statement of the problem The bond strength between the denture basis and the soft relining material is of crucial importance for the duration of the so called two-layer dentures. The aim of the study The aim of the study is to propose a new simple method for increasing the bond strength between denture basis and soft relining material. Materials and methods Two commonly used dental materials were used PMMA Meliodent - acrylic resin and Elite Soft Relining soft relining (silicone) material.60 cylindrical samples were made (length (L) =30mm and diameter (D) =5mm). Half of this length (15mm) was made of PMMA Meliodent and the other half (15mm) was made of VPS Elite Soft Relining. Acrylic pearls for additional mechanical retention were also used. A total number of 60 samples were made, divided equally in two groups. For the first group the bond was realized only by means of the manufacturers primer. It served as a control group. For the second group except the primer, four acrylic pearls per sample were added. Both groups were tested for tensile bond strength with the help of a device LMT-100 (LAM Technologies). The results were analyzed by using ANOVA test method. Results The mean tensile bond strength of the first (control) group was 0.744 MPa and for the second 1.380 MPa respectively. Conclusion Within the limitations of the study it was concluded that the use of additional mechanical retention increases the bond strength almost twice, compared to the control group.
