OptiBond XTR 3rd Party Data


Exceptional Bond Strengths


Comparative internal testing showed higher uncut enamel and dentin bond strengths were achieved with OptiBond XTR vs. leading adhesives. To verify bond performance, OptiBond XTR was tested independently at Dental Biomaterials Research Laboratory, State University of New York at Buffalo. In the study performed at the Dental Biomaterials Research Laboratory, OptiBond XTR demonstrated statistically superior dentin bond strengths vs. ClearFil SE Bond and Xeno IV. On cut enamel, OptiBond XTR demonstrated statistically superior enamel bond strengths to ClearFil SE Bond, Xeno IV, and OptiBond FL.

Case Studies by Dr. Stephen Poss


Clinical Case I

A 40-year-old female had two failing amalgam restorations on teeth numbers 18 and 19. The amalgams were removed. The OptiBond XTR Primer was placed on all prepared areas for 20 seconds and air-dried to evaporate the solvent.

The OptiBond XTR adhesive was applied for 15 seconds and air-dried. The adhesive was light-cured for 10 seconds. While all composites are compatible with OptiBond XTR, Herculite Ultra was placed. The occlusion was checked and the restoration polished.

Clinical Case II

This 70-year-old lady was in need of several crown and veneer restorations due to the failure of composite restorations on teeth 5-12. OptiBond XTR can be used with any porcelain. In this particular case, E-Max (lithium disilicate) was used for all the anterior crowns and veneers. Before the porcelain was seated, the restorations were thoroughly cleaned. That included sandblasting with aluminum oxide. Each restoration was then etched with hydrofluoric acid.

Once the hydrofluoric acid was rinsed off, a coat of Kerr's Silane Primer was placed in each restoration and allowed to air dry. Once the provisionals were removed, the teeth were cleaned, isolated, and dried. A coat of the OptiBond XTR primer was placed on each tooth for 20 seconds and then air-dried.

A coat of the OptiBond XTR adhesive was then placed on each tooth for 15 seconds. The solvent evaporated off, and each tooth was light-cured for 10 seconds.

Any light-cured, dual-cured, or self-cured cements can be used since OptiBond XTR is compatible with all dental materials. This clinician chose to use Kerr's NX3 Nexus Third Generation light cure resin cement.

Curing all surfaces for 20 seconds is recommended once the restoration is seated.

OptiBond XTR offers the clinician the best of both worlds. The dentist can use one adhesive system for both direct and indirect restorations, and use it with the confidence that it will provide a strong bond to both cut and uncut enamel, without postoperative sensitivity concerns.

This can save time and expense. In this economy, that's always a win-win for both the clinician and the patient.
