Dental cement is a composite material that's used in the tooth-restoration process. It's also used for filling cavities, crowns, and bridges. If you don't mix your dental cement correctly, you could end up with a product that doesn't set properly or fails to adhere to your client's teeth properly. It's important for dentists and technicians alike to understand how to dispense dental cement so they can ensure proper mixing techniques are employed when dispensing their products on patients' teeth during treatment sessions.
Types of Dental Cement
There are several types of dental cement used in dentistry. Mainly classified into two types, they are permanent dental cement and temporary dental cement, each with its specific properties and applications. Here are some common types of permanent and temporary dental cement:
Permanent Dental Cement:
Zinc Phosphate cement: Luting (cementing) permanent crowns and bridges, High-stress-bearing areas, Good strength and durability.
Polycarboxylate cement: Luting permanent crowns and bridges, Used when a less irritating cement is needed, with Good chemical adhesion to the tooth structure.
Glass Ionomer cement (GIC): Restorative material for cavities, particularly in primary teeth, Luting agent for crowns, bridges, and orthodontic bands, Releases fluoride, offering some caries prevention.
Resin-Modified Glass Ionomer cement (RMGI): Combines the properties of glass ionomer and resin-based materials; used for restorations, luting, and as liners with better esthetics and strength compared to traditional GIC.
Composite Resin cement: Bonding veneers, inlays, onlays, and aesthetic restorations, Excellent esthetics, Requiring curing with a light source.
Adhesive Resin cement: Bonding veneers, inlays, onlays, and ceramic restorations Provide a strong and esthetic bond.
Temporary Dental Cement:
Zinc Oxide Eugenol (ZOE) cement: Temporary restorations, Sedative liners, Impression materials, Low-stress-bearing areas.
Temporary Filling Materials: Used for temporary fillings in emergency situations, Usually based on zinc oxide eugenol or other temporary materials.
Temporary Crown and Bridge Material: Used for fabricating provisional crowns and bridges in the dental office; customizable and easy to shape.
Each type of dental cement has its specific properties, indications, and contraindications. The choice of cement depends on factors such as the type of restoration, clinical situation, and patient needs. Dentists carefully select the appropriate cement to ensure the success of dental procedures and the long-term health of the patient's oral structures.
Importance of Proper Dispensing
Dispensing is a critical step in the mixing process, as it allows for proper mixing and adhesion. It's also important that you be aware of best practices when dispensing the dental cement. It would help if you always used a properly calibrated dispenser and dispensing tip so that your concrete mixes evenly and smoothly. If you don't have adequate control over the amount of dental impression material dispensed, then there's no way for the cement to properly bond with your tooth enamel or dentin (the harder part). This can lead to issues like weak bonds or restoration failure due to poor adhesion between different parts of your teeth—and these problems won't go away by themselves!
Dispensing Tools and Equipment
Dispensing tools and equipment are essential in dental applications to ensure precise and controlled dispensing of various dental materials. These tools play a critical role in dental procedures, from impression-taking to restorative work. Here are some dispensing tools and equipment commonly used in dental applications:
