EQUIA® Restorative System: Outstanding Performance Confirmed By Several Long-Term Clinical Trials

by adminjay


Introduced in 2007, the EQUIA® restorative system quickly proved to be a new standard in restorative technology, offering esthetically pleasing bulk-fill posterior restorations and an advanced option to overcome the limitations of amalgam, composite and conventional glass ionomer restoratives. Over the years, EQUIA® has inspired a number of prominent research groups to evaluate its clinical performance in several short- and long-term trials.

Mounting Evidence For EQUIA®
A significant number of articles published in high-ranked journals brought in light the remarkable performance of EQUIA® in Class I and II restorations after two- and three-year follow-up periods (Friedl et al1; Klinke et al2; Olegario et al3; Fatidou et al4; Lopez et al5). Two additional studies (Turkun et al6 and Basso et al7) evaluated EQUIA® restorations after longer
periods of six and seven years respectively, concluding about its reliability and durability for Class I, II and V restorations.

Other leading studies compared EQUIA® to conventional resin composites. For instance, Menezes Silva et al8 and Kupietzky et al9 demonstrated that EQUIA® had similar rates of success
when compared to a composite resin in Class II restorations after three years.

After a 5-year trial, Molina et al10 revealed EQUIA®’s optimal performance when treating special care patients. EQUIA® also proved to be a trustworthy restorative option for noncarious cervical lesions after one and three years as described by Vaid et al11 and Celik et al12 respectively. A randomized controlled trial leaded by Heck et al13 showed, after a six-year follow-up, the satisfactory performance of EQUIA® to restore two- or three-surface class II restorations.

Finally, Gurgan et al14. conducted a notable 10-year clinical trial reporting an outstanding success rate of 100% for the EQUIA® restorative system in class I and II cavities.

Glass Hybrid Materials: A New Era Of Performance
Building on the extensive and positive clinical evidence of the EQUIA® restorative system, GC introduced EQUIA Forte®, the first glass hybrid, in 2015, and offering an unprecedented option for long-term restorations.

The interim results of clinical studies show the suitability of EQUIA Forte® as a longterm material to restore extended size Class II cavities.* Gurgan S. et al15 compared EQUIA Forte® to a micro-hybrid composite; concluding that, after four years, both materials presented optimal surface and marginal adaptation characteristics. The EQUIA Forte® multicenter study (Miletic I. et al16) compares the glass-hybrid to a nano-hybrid resin composite (Tetric EvoCeram, Ivoclar Vivadent) and the two-year interim results have shown similar clinical performance for both materials.

Backed by years of extensive research and academically reviewed publications, this literature review provides clinicians with the unwavering confidence in glass hybrid restorative systems as an optimal long-term restorative alternative.

The latest Glass hybrid, EQUIA Forte® HT, offers increased esthetics and strength compared to its predecessor, EQUIA Forte®; confirming that glass-hybrids are a trustworthy long-term restorative option for the dentist, while still being cost effective for patients.
