Dental Adhesives

Dental adhesives encompass a broad category of materials used to bond restorations to tooth structure and to secure removable prosthetics. In restorative dentistry, adhesive systems create a micromechanical and chemical bond between composite resin restorations and tooth enamel or dentin, enabling conservative preparations that preserve natural tooth structure. Denture adhesives are a separate category designed to improve the retention and stability of removable dentures. Available as creams, powders, strips, and pads, they fill the gap between the denture and the oral mucosa, creating a seal that resists dislodging forces. Zinc-free formulations are recommended for long-term use to avoid potential zinc-related health concerns. Implant cement is another adhesive type used to attach implant-supported crowns and bridges to abutments. Both temporary and permanent cements are available, with the choice depending on whether the clinician wants the ability to retrieve the restoration. Proper adhesive selection and technique are crucial for the longevity and success of all types of dental restorations.
