Comparison of the adhesion of adhesive pastes on removable dental prostheses from different commercial companies

Abstract

The use of conventional removable dental prostheses shows the lack of retention and stability, so the use of adhesives for prostheses has been generalized to improve their resistance to detachment. The adhesion of adhesive pastes in removable dental prostheses of different commercial companies was compared. The empirical component involved an in vitro experiment using two adhesive pastes: Corega and Denta Firme, applied on acrylic discs that were previously hydrated and then placed on glass slabs to measure the adhesion strength. This process involved the uniform application of 5 ml of each paste on the discs, followed by a hydration period of 8 minutes. Adhesion strength was measured using a digital scale, recording the highest value obtained during vertical debonding of the disc from the tile. This study revealed that the differences in the bond strength of the adhesive pastes evaluated for dentures are minimal. Denta Firme demonstrated the highest bond strength in the short term. It is concluded that the study failed to determine the durability of the bond strength of the pastes over time. However, the findings indicate that the use of adhesives significantly improves the retention of conventional removable or total dentures. Consequently, it is recommended that dental professionals carefully choose the most appropriate adhesive for each patient, considering individual characteristics and specific needs, in order to take full advantage of the benefits offered by these products
