Ivoclean Instructions: A Comprehensive Guide
Ivoclean, by Ivoclar Vivadent, is a crucial cleaning agent for dental restorations, ensuring optimal adhesion before cementation, especially with zirconia materials.
This guide details the proper application and protocols for Ivoclean, covering preparation, application, and post-application procedures for consistently successful outcomes.
Understanding Ivoclean’s Purpose
Ivoclean’s primary function is to remove contaminants from restoration surfaces, creating an ideal environment for bonding agents to effectively adhere. Specifically, it addresses the issue of phosphate affinity, particularly relevant with zirconia restorations.
Zirconia exhibits a strong attraction to phosphate ions present in saliva, hindering the bonding process. Ivoclean is a supersaturated zirconia oxide solution; it effectively competes with the zirconia restoration for these phosphate ions.
This competition draws phosphate ions away from the restoration’s surface and into the cleaning agent itself, effectively “freeing up” the bonding sites. Consequently, the subsequent application of a primer, like Monobond Plus, can establish a robust and durable bond.
While not always strictly necessary for materials like e.max, Ivoclean is indispensable for zirconia, ensuring optimal cementation and long-term restoration success by mitigating phosphate interference.
Zirconia vs. Other Materials: Why Ivoclean?
The necessity of Ivoclean hinges significantly on the restoration material. While cleaning steps are always beneficial, Ivoclean’s unique properties are most critical when working with zirconia.
Unlike glass ceramics, lithium disilicate, or composite materials, zirconia possesses a high affinity for phosphates found in oral fluids. These phosphates interfere with adhesive bonding, compromising the long-term integrity of the restoration.
Materials like e.max and composites don’t exhibit this strong phosphate attraction, making Ivoclean less crucial, though still potentially beneficial for removing general surface contaminants.
However, for zirconia, Ivoclean isn’t merely a cleaner; it’s a preparatory step that actively modifies the surface, removing phosphate interference and creating a receptive surface for bonding agents. This targeted action is why it’s a cornerstone of zirconia cementation protocols.
The Role of Phosphate Affinity
Zirconia’s strong attraction to phosphate ions, prevalent in saliva, is the core reason for utilizing Ivoclean. These phosphate ions readily bind to the zirconia surface, creating a barrier that hinders the adhesion of dental primers and cements.
Ivoclean’s formulation is a supersaturated zirconia oxide solution. When applied, it initiates an ion-exchange process, effectively displacing the phosphate ions from the zirconia surface.
This displacement “frees up” the bonding sites, allowing the subsequent application of a primer, like Monobond Plus, to establish a robust and durable adhesive bond. Without this preparatory step, bond strength is significantly reduced, increasing the risk of restoration failure.
Essentially, Ivoclean doesn’t just clean; it chemically conditions the zirconia surface, optimizing it for optimal bonding by mitigating the disruptive effects of phosphate contamination.
Preparation Before Using Ivoclean
Prior to Ivoclean application, thoroughly rinse and dry the restoration after the try-in procedure to remove any debris or contaminants present on the surface.
Restoration Try-In and Initial Rinse
Begin with a meticulous restoration try-in to verify proper fit, aesthetics, and occlusion. This crucial step ensures the final result meets expectations before proceeding with bonding. Following the try-in, a comprehensive rinse is paramount.
Utilize a strong water spray to effectively remove any temporary cement, debris, or contaminants accumulated during the try-in process. Pay particular attention to marginal areas and occlusal surfaces, ensuring no residue remains. This initial rinse prepares the restoration surface for optimal Ivoclean application.
A thorough rinse is not merely about removing visible particles; it’s about establishing a clean foundation for subsequent bonding procedures. Inadequate rinsing can compromise the effectiveness of Ivoclean and ultimately, the longevity of the restoration. Ensure complete removal of all extraneous materials before moving to the next step.
