A Comprehensive Guide to Using Luting Cement for Dentists

Are you carrying out a repair process? Dental luting can act as either a facilitator or an inhibitor of the quality of your directly bonded restorations. It is essentially left to the prostheses to accomplish the desired function and hence is the key element of success in any type of restorative dentistry. For success, you are advised to select the best luting cement, such as RMGIC (Resin-Modified Glass Ionized Cement). Let us see why this works for dentists who use luting cement.

What is Dental Luting?

The dental luting technique is the means of bonding indirect restorations, for instance inlays, outlays, veneers, bridges and crowns to the enamel surface of teeth. An adhesive is utilized here in order to cement the restoration base to the tooth surface with a type of dental cement.

RMGIC is one of the traditional cementation systems which is normally necessary when enamel support (adapters etc.) is used in the preparation. Bonding supports an additional adherence or when a beautiful look is desired.

Here are some important aspects of dental luting you need to understand:

  • Cementation: It is a lot to do with the working of attaching the dental restoration to the structure of the tooth. It features the choice of an appropriate Resin Modified Glass luteing agent, teeth surface preparation, applying the cement, and the ultimate seating of the restoration. Cementation of the dental components guarantees the expected interactions such as perfect fit, reliability and retention of the restoration used.
  • Bonding: It means the connection of the adhesive cements with the restoration material or tooth with a micromechanical bond. It increases the properties like stability and strength of the cemented restoration by much extent thereby cheating the risk of debonding or failure. 
  • Retention: It is the boundary between the healed tissue and the space into which the insertion takes place. The luting agent used plays a vital role but the one that is placed on the complying tooth structure determines the strength of the restoration. Retention is effective in preventing the failure of surveillance at standard facial functions at the time of standard oral functioning.
  • Adhesion: It refers to the molecular attraction between two dissimilar items, like the luting agent and the tooth structure. 

Different Types of Luting Agents for Dentists

As you wish to learn about RMGIC luting cement, it is imperative that you understand the different types of luting agents. These agents offer immense variety, especially with respect to indications and unique properties. 

When you choose the best luting agent, some of the core factors you need to consider are the restoration’s material, type of restoration, clinical conditions, aesthetic requirements, and tooth structure. Here are some of the common types you should know about:

  • RMGIC Luting Cement or Agent: RMGIC stands for Resin-Modified Glass Ionomer Cement. It is a type of hybrid luting cement or agent that blends the advantages of glass ionomer cement and resin-based materials. This luting agent delivers ease of use, tooth protection, speed, and the overall strength of the resin material. RMGIC luting cement offers ample moisture tolerance along with outstanding chemical adhesion to the tooth surface. This agent is usually utilized for the cementation of porcelain-fused-to-metal and metal crowns. The agent offers impressive aesthetics, improved adhesion to the tooth structure, and fluoride release.
  • GIC, or Glass Ionomer Cement: It is a versatile luting agent that chemically bonds to specific restoration materials and tooth structure. This luting agent releases fluoride to prevent secondary caries. GIC features impressive biocompatibility and can be used for cementing inlays, outlays, bridges, crowns, and orthodontic bands. 
  • Polycarboxylate Cement: It is a type of powder-liquid agent that delivers impressive adhesion to specific restorative materials and tooth structure. It releases fluoride while featuring moderate strength. The agent is commonly used for the cementation of cast restorations, like bridges and crowns. Polycarboxylate cement features reduced pulpal irritation and better biocompatibility. 
  • Zinc Phosphate Cement: This cement category has been in widespread use in the field of dentistry for several years. It is an effective powder-liquid agent that chemically bonds to the tooth structure through some acid-base reaction. It delivers good durability and strength, making it an ideal option for cementing inlays, outlays, bridges, and crowns. However, it can lead to pulp irritation due to its acidic levels.

Important Considerations for Dental Luting

If you wish to optimize the process of dental luting, it requires in-depth assessment and decision-making. As dentists, you should prioritize the importance of in-depth patient assessment, selection of the right curing process, giving attention to viscosity, and ensuring function & aesthetics.

  • Patient Assessment

The process of dental luting starts with an in-depth assessment of the patient. It would involve assessing the patient’s specific requirements and the current condition of the patient’s oral cavity. Additional factors like substrate selection, aesthetic requirements, and tooth preparation should also be considered. The selection of the restoration material and the priorities of the patient will determine the choice of the luting cement or agent.

  • Aesthetics and Function

In the field of dental luting, achieving a perfect balance between aesthetics and functionality is crucial. Anterior teeth (usually visible while smiling) give preference to aesthetics. On the other hand, posterior teeth focus on more function-related aspects like chewing efficiency. 

Based on teeth preparation, you can choose either the full adhesive application or the simplified self-adhesive application.

  • Method of Curing

Dual-cured and light-only curing cements are the best options out there. Light curing is considered for thinner restorations, like veneers. On the other hand, dual-cured cements are preferred for thicker restorations requiring a reliable set.

  • Viscosity

In the cementation process, viscosity helps with easy cleanup and proper flow. The ideal cement should feature ideal viscosity to allow the cement to flow under pressure without excessive thickness. 


If you are involved in the field of dentistry, it is recommended to master the skill of dental luting by understanding its process comprehensively. The selection of the right luting cement is pivotal for the success of dental restorations. Brands like Dental Avenue are at the forefront of such innovations, offering advanced materials that significantly enhance clinical outcomes. The ongoing innovations with respect to dental materials and practices highlight the significance of continuous learning and adaptation by dentists to ensure optimal patient care. Engaging with trusted brands such as Dental Avenue can provide access to the latest products and training necessary for achieving excellence in dental procedures.
