Consultants’ Comments

• “The long-term success of G-aenial Bond builds my confidence about using GC America’s bonding and restorative systems.”
• “The bond strength of G-aenial Bond is clearly proving to be excellent as I have seen almost no marginal discoloration in the restorations during the past four years.”
• “The retention and lack of sensitivity are imperative to my patients. Using G-aenial Bond gives me confidence I can provide this.”

Description

G-aenial Bond is a 7th-generation bonding agent designed for the selective etching technique (self-etch for dentin, etch and rinse for uncut enamel). This one-component, self-etching, light-cured adhesive does not require refrigeration. It is indicated for the bonding of light-cured composites and compomers to tooth structure. It can also be used to bond dual-cured luting and core build up composites to tooth structure as long as these materials are light cured. G-aenial Bond, is available in a 5 mL bottle or 0.1 mL Unit Dose packs.

Clinical Evaluation Protocol

• G-aenial Bond was used to place a total of 208 restorations.
• At four years, 154 of these restorations were available for recall. Ninety-seven restorations were three- to four-years old (Figures 1 and 2).
• A variety of universal composites were used, of which 50% were G-aenial Universal Flo.

Clinical Observations

Lack of Marginal Discoloration

Ninety-one percent of the restorations showed no signs of marginal staining (Figure 3). Nine percent of the restorations showed slight to moderate marginal staining, including three restorations that required replacement or repair due to chipping.

Lack of Postoperative Sensitivity

No patients reported any long-term sensitivity in the teeth where G-aenial Bond was the bonding agent used (Figure 3).

Retention

No restorations placed using G-aenial Bond as the bonding system debonded during the four years in service. FIGURE 3.

Summary

Two hundred and eight composite restorations were placed over the past four years, using G-aenial Bond as the bonding system. Ninety-seven restorations that were three- to four-years old were available for recall. All restorations received excellent ratings for resistance to marginal discoloration, lack of postoperative sensitivity and retention. None of the restorations debonded over the four-year period. G-aenial Bond received a 98% clinical performance rating at four years.
