Bonding: The Way To Do Peak
One of the most critical component of composite restoration is bonding. A lot of dentists sometimes ignore the significance of the quality of their bonding material and the right process to do it because more often than not they just use what comes with their composite resin kits. This is one of the issue that needs to be address properly and make the dentists aware that the strength of their restoration largely depend on the bonding strength. So, the quality of the bonding agent whether total etch or self-etch application and the manner it is applied and cured are really important.
One of the best bonding agent available currently in the market is Peak. The Peak Universal Adhesive System features a universal bonding agent that is compatible with both self-etch and total-etch techniques. Its universal formulation works with all bonding substrates—including dentin, enamel, porcelain, metal, composite, and zirconia—and it provides superior bond strengths, making it the ideal choice for all bonding procedures, including post and core procedures. With 7.5% filler, its viscosity has been optimized for minimal film thickness (2μm) and superior strength. The addition of chlorhexidine in Peak Universal Bond may provide the added benefit of improving long-term bond strengths.
Because bonding success begins with a quality etch, both Peak SE Primer and Ultra-Etch are formulated to create an optimally prepared surface for bonding-resin penetration. When Peak Universal Bond is applied to the prepared surface, the result is unsurpassed bond strength and complete resin impregnation without voids, which reduces the possibility of residual patient sensitivity.
However, all of these benefits will require proper application if you want to maximize its benefits. Did you know that Peak Universal Bond should always be light cured before layering composite and luting veneers? A number of clinicians are using a new technique that involves waiting to cure the bonding adhesive until after the first layer of composite is placed. We do not recommend this with Peak Universal Bond. Our internal testing reveals that the bond strength becomes jeopardized when Peak is not light cured before the composite is placed. We also tested this with PermaShade® LC and the results were the same. The concern related to veneers was that that light curing the adhesive first might produce a thick layer that would affect the fit of the restoration. Because Peak is only 7% filled, film thickness should not be a concern—especially because it can be thinned to as low as 2µm if needed. Although it may seem more efficient to cure the bonding adhesive at the same time as the composite or the veneer cement, the bond strengths will be 13% to 30% weaker if you don’t light cure first! This data reinforces why it’s important to follow Ultradent’s recommended instructions; using the proper techniques will ensure optimal bond strengths and quality restorations.
Do the bonding with the right bonding agent and application and you won’t go wrong with your restoration. Peak Universal Bond is available in two delivery options: syringes for intraoral control, minimal waste, and preservation of critical, oxygen-sensitive ingredients, and bottles for easy dispensing and convenient delivery with an applicator.
