Description
Waldent Glasseal Glass Ionomer Liner LC is an innovative light-cured dental cement designed to provide optimal benefits by harnessing the advantages of both glass ionomers and composites. This remarkable product serves as a resin-reinforced glass ionomer liner cement, offering a unique combination of properties to enhance dental restorations. By chemically bonding to the tooth structure, Glasseal establishes a durable and reliable foundation for dental restorations. The fluoride-releasing capabilities of Glasseal add another layer of benefit, helping to promote remineralization and strengthen the tooth structure while offering caries protection. With its cutting-edge formulation, Glasseal represents a significant advancement in dental materials, providing clinicians with a versatile solution that combines the best features of glass ionomers and composites. By offering superior aesthetics, bonding strength, and fluoride release, Glasseal supports long-lasting and aesthetically pleasing dental restorations, ensuring both functional and cosmetic satisfaction for patients.
Indications:
- Used as a liner under various filling materials to enhance biocompatibility, provide a
protective barrier, and facilitate enamel remineralization through fluoride release. - When preparing cavities, the light-cure glass ionomer cavity liner is indicated for
pulp protection, acting as a barrier against potential damage and stimulating
enamel remineralization. - It is particularly useful in composite restorations where it helps minimize post-operative sensitivities. It compensates for marginal gap formation through volume expansion, enhancing the marginal seal and reducing the risk of sensitivity.
Contraindications:
- If the patient has a known allergy or sensitivity to any of the components of the material
Features
- High bond strength: Glasseal ensures a strong and reliable bond to both tooth structure and restorative materials, promoting long-lasting and secure restorations.
- Thermal compatibility: The formulation of Glasseal is designed to be thermally compatible with tooth structure, minimizing the risk of post-operative sensitivity commonly associated with dental procedures.
- Minimal shrinkage: Upon curing, Glasseal exhibits minimal shrinkage, resulting in improved marginal integrity and reduced microleakage. This feature enhances the longevity of the restoration.
- Low solubility: Glasseal demonstrates low solubility in oral fluids, contributing to the long-term stability and durability of the liner within the restoration. This ensures the liner maintains its integrity over time.
- Proprietary bioactive technology: Glasseal incorporates a unique bioactive glass filler, which is radiopaque, high ion-releasing, and bioactive. This technology promotes the release of ions, aiding in the remineralization of enamel and offering protection against caries.
- Fluoride release: Glasseal exhibits the ability to release fluoride, which further supports enamel remineralization and serves as a preventive measure against tooth decay.
- Radiopacity: Glasseal is radiopaque, enabling clear visibility and precise assessment of the restoration on radiographic images. This characteristic facilitates accurate monitoring and evaluation of the restoration’s integrity.
Key Specifications
- Composition: Urethane Dimethacrylate resin, Bisphenol A Glycidyle Methacrylate, Barium Sulphate, FluoroAluminoSilicate Glass Powder, Silanated Barium Glass Powder (Filler), Amorphous Fumed Silica, Photoinitiators (Curing agent) and Stabilizers.
Direction to Use
- Begin by ensuring proper isolation, preferably using a rubber dam, to isolate the treatment area and minimize contamination. Additionally, protect areas close to the pulp by applying a thin layer of calcium hydroxide material if necessary.
- Prepare the cavity with minimal tooth reduction, preserving as much healthy tooth structure as possible. Take care to maintain the integrity of the surrounding enamel and dentin surfaces.
- Apply a suitable bonding agent to both the dentin and enamel surfaces according to the manufacturer’s instructions. This step enhances the bond strength between the tooth structure and the restoration.
- Replace the cap of the Glasseal syringe with a dispensing tip. Before application, confirm the consistency of the liner by expressing a small drop onto a pad.
- Apply Glasseal in a thin layer, covering the cavity floor and walls until the desired thickness is achieved. Avoid extending the liner onto the cavity edges to facilitate proper adaptation of the composite material later.
- Use a light-curing unit with a wavelength range of 400-500 nm and a light intensity of at least 500 mW/cm². Position the unit’s optical probe as close as possible to the filling material during the recommended curing time of 20 seconds. This ensures thorough and effective light curing of the glass ionomer liner.
- Once the Glasseal is light cured, proceed with the placement of a light-cured composite material following the manufacturer’s instructions. Layer the composite incrementally, using appropriate techniques to achieve the desired shape and contour of the restoration.
