Two New Products from GC America by Dr. Thomas Dudney

GC America has recently introduced two new products, G-Premio BOND™ and G-ænial Sculpt®. G-Premio Bond is a one bottle, universal (8th generation) adhesive that has a reliable bond to enamel and dentin and can be used in conjunction with a total etch, self etch, or selective etch technique. It is compatible with all direct restoratives and due to a very thin film thickness (3 µm) can also be used with indirect restorations when light cured. It features a new bottle design for more precise dispensing and temperature control and can be used to treat dentin hypersensitivity.

G-ænial Sculpt is a light-cured, universal, nano-hybrid composite with a uniform nano-filler dispersion that provides excellent wear resistance and a very low particle plucking rate. It is available in 17 shades (including opaque and enamel shades) and with its excellent polish and high gloss retention can be used equally well for anterior and posterior restorations. In addition, GC testing shows additional polish can be gained in mouth for up to 12 months through daily tooth brushing.

The following clinical case will demonstrate the use of G-Premio BOND universal adhesive and G-ænial Sculpt universal, nano-hybrid composite:



After administering a local anesthetic, tooth #31 was isolated with a rubber dam for the removal of the occlusal-buccal amalgam.


After removal of the amalgam and recurrent decay, the tooth was treated with an anti-microbial, rinsed, and lightly air dried.


A total etch technique was based on clinician preference and a desire for higher bond strength to uncut enamel. A ten second application (following manufacturer instructions) of G-Premio BOND was followed by air drying to evaporate the solvent followed by light curing.


Next, a layer of G-ænial™ Universal Flo was placed in the floor of prep and light cured.


G-ænial Sculpt in unitip delivery (Shade A1) was placed, shaped, and light cured in two increments.


G-ænial Sculpt has excellent handling properties, in that it is easy to shape and stays in place.


The rubber dam was removed, occlusion checked, and the restoration was polished. The barium glass filler in G-ænial Sculpt provides a superior polish and high gloss retention and its chameleon effect blends well with surrounding tooth structure. 


Furthermore, G-ænial Sculpt is self-polishing with tooth brushing and is very radiopaque, making it easy to see on radiographs.

Clinical Evidence: EQUIA Performs Like Composite in Class I and Class II Fillings

Results from an independent four-year randomized clinical trial* which evaluated the clinical performance of EQUIA were recently published in a leading oral health journal. The study, led by Professor Sevil Gurgan from the Department of Restorative Dentistry at Hacettepe University in Turkey, concluded that EQUIA performs like composite in Class I and Class II fillings, offering a durable solution for posterior restorations.

These findings support the growing evidence of EQUIA’s favorable properties as a restorative solution, highlighting the evolution of glass ionomer restorative materials in recent years and paving the way for modern dentistry.

Reliable posterior restorations

The clinical trial was conducted on permanent posterior teeth both in Class 1 and Class 2 carious lesions of young patients with the average age of 24 years. A total of 140 fillings (80 Class 1 and 60 Class 2) in 59 patients was restored with EQUIA and Gradia restorative systems. Two independent examiners evaluated at baseline and at one, two, three, and four years post restoration according to the modified US Public Health Service criteria. Polyvinyl siloxane impression negative replicas at each recall were observed under scanning electron microscopy (SEM) to evaluate surface characteristics.

The clinical efficacy of EQUIA and Gradia Direct Posterior was determined by evaluating the anatomical form, color match, marginal discoloration, marginal adaptation, secondary caries occurrence, and retention at one year and annually for four years.

The trial’s results showed that neither EQUIA nor Gradia restorations were downgraded in anatomical form, secondary caries, surface texture, postoperative sensitivity, and color match during the four years. Based on these results, Professor Gurgan and the team concluded that the use of both materials for the restoration of posterior teeth exhibited a similar and clinically successful performance after four years.

“Glass ionomer cements were introduced to the dental market as a replacement for amalgam restorations, particularly in Europe where in many countries now, the use of amalgam for tooth restorations decreases day by day. The demand of patients for non-metallic restorations has also increased a lot in recent years. The ongoing clinical trial results show that the new generation of glass ionomer cements or the reinforced glass ionomer cements could be used an alternative to amalgam or other tooth-colored restorative materials in permanent dentition,” Professor Gurgan commented.

This is good news for dentists who want to offer their patients a cost-effective and durable restoration that is aesthetic and also has the oral health benefits of a glass ionomer restorative.

On-demand webinar: Esthetic Alternatives to Direct Composites with Mark Pitel, DMD, FAGD, FACD, FIADFE

Duration: 65 minutes

Date: On demand

Class overview:

While many people have some level of knowledge regarding glass ionomers, very few are aware of the advances that have been made since this category first came on the market over 30 years ago. The versatility, vastly improved esthetics, and ease of use over the earliest generations have made this a reemerging and rapidly growing area of dentistry. In fact, some recent studies have shown that properly placed posterior glass ionomer restorations may actually offer a superior clinical life span to direct composites.

Incorporating glass ionomer cement in your clinical practice

Dr Mark Pitel discusses the properties of glass ionomer cements and how the materials have evolved in recent years. He outlines how the features such as adhesion, biocompatibility, easy placement, anti-cariogenicity, and resin modifications make the material a good solution in a number of restorative situations.

Techniques and tips are described on how to achieve esthetic and durable results with glass ionomer cement in a wide range of restorative conditions in comparison to composites available on the market. Clinical cases are shown and academic evidence to support these are also shared.
