Products - Embrace™ WetBond Overview - Product Review
The increasing focus on prevention and early childhood care, the need to serve a broader demographic and expanding population, and the emergence of bioactive materials that directly benefit our patients, offer new opportunities for the dental profession.
Advances in oral health care will involve harnessing technologies that unlock nature’s healing powers with bioactive materials that behave favorably in the moist oral environment, neutralize conditions that cause dental caries, and maximize the potential for remineralization.
Pulpdent has developed Embrace WetBond, a bioactive ionic resin that is designed to take advantage of the moisture that is always present in the mouth. Embrace is moisture friendly and even contains a small amount of water. It has attributes that mimic nature and respond to changes in the oral environment.
The development of bioactive materials is inspired by nature, where water is the source of life. In the oral cavity, saliva is the vital stream and is rich with water and ionic components.
The oral environment is exposed to continuous pH changes, and saliva and tooth structure participate in an endless cycle of mineral exchange. When the pH is low, the demineralization process releases calcium and phosphate ions from the tooth surface. As the pH rises, these ions are available to interact with the fluoride ions in our saliva and precipitate onto teeth in the form of fluorapatite.
Bioactive materials have the potential for dynamic behavior because they are partly water-based, or have phases with significant water content. Ionization occurs when water is present and allows these materials to react to changes in the ambient conditions. This is often referred to as “smart” behavior.*
Most traditional dental resins are hydrophobic, repel saliva, and require a dry field. They are designed to be passive and to have a relatively neutral existence in the mouth. This passive approach does not take advantage of the positive gains that can be achieved with active materials that behave in a dynamic fashion in the oral environment.*

Embrace products are formulated with a patented, moisture friendly, ionic resin that contains a small amount of water. They are bioactive, mimic nature and respond to changes in the oral environment.
In the presence of moisture, the uncured Embrace resin is acidic and simultaneously etches, ionizes, and adheres to tooth structure.
The ionic resin contains phosphate groups. Through an ionization process that is dependent on water, hydrogen ions break off from these groups and are replaced by calcium in tooth structure. This ionic interaction binds the resin to the minerals in the tooth, forming a strong resin-hydroxyapatite complex and a positive seal against microleakage.
The ionic resin exhibits exceptional marginal integrity, sealing ability against bacterial leakage, and intimate adaptation to tooth structure. It releases a great amount of phosphate, significantly recharges with fluoride, and contains an acidic monomer with antimicrobial properties that enhances the interaction between the resin and tooth structure.
When cured, Embrace resin is not a static material. It is a dynamic, bioactive system. Calcium, phosphate and fluoride from supplements and dietary sources recharge the saliva and Embrace ionic resin.
