What role does the adhesive spray play in prosthodontics?

In prosthodontics, the adhesive spray plays a crucial role in ensuring that impression materials adhere properly to the impression tray during the impression-taking process. When a dental professional applies the adhesive spray to the tray, it enhances the bond between the tray and the impression material, preventing any dislodgement or movement that could compromise the accuracy of the impression. This secure attachment is essential for obtaining a precise representation of the dental arches and surrounding tissues, which is critical for crafting well-fitting prosthetic devices such as dentures or crowns.

The effectiveness of the adhesive spray directly impacts the quality of the impression, as any imperfections could lead to fitting issues later on when the prosthesis is manufactured. Therefore, its use is fundamental in achieving reliable and accurate results in dental prosthetics.
