Results with Glass Hybrids in the posteriorGlass Ionomers have become considered as a permanent material for the restoration of posterior teeth. The objective of this presentation is to discuss the long-term clinical performance of GIs in comparison to widely used composite resins in posterior teeth with the current published data.
Glass ionomers (GIs) have been recommended to be used as restorative cements, cavity liners/bases, and luting cements since their introduction in dentistry in the early 1970s. They have certain unique properties that make them favorable. This includes chemical bonding to enamel and dentin, thermal expansion similar to that of tooth structure, biocompatibility, uptake and release of fluoride, and decreased moisture sensitivity. The main disadvantages of GIs include their susceptibility to water uptake and loss, particularly in the initial setting reaction, as well as their brittle material character. These drawbacks have supposedly been ameliorated in modern, recently launched high-viscosity GIs. During the past years, they have undergone major changes. Advancements in their formulations led to better properties, such as improvement in handling characteristics, wear resistance and strength and decreased setting time, which have widened the indication spectrum of GIs. They have certainly progressed remarkably from their inception to their present-day use as the permanent restorative material choice for a variety of clinical situations.
As there is a universal decrease trend in the mostly used posterior restorative material-amalgam-usage all over the world, the long term clinical success of the materials replacing amalgam certainly requires to be evaluated. For this reason, long term clinical trials are needed and the ultimate and most reliable methods to evaluate the longevity of restorations are randomized, controlled clinical trials. Despite the expanding use of GIs as permanent restorative material for posterior restorations, until now there have been very few clinical trials on their performances. As it is reasonable to expect adequate evidence of biological safety, clinical efficacy and longevity; in this presentation, long term durability of GIs in the restoration of Class I and Class II cavities and as well as non caries cervical lesions comparing with composite resins which are routinely preferred will be discussed with the latest published data.
Learning objectives
The audience will be able to:
- Understand clinical behavior of restorative GIs
- Apply scientific information from the literature for clinical decisions about the use of restorative GIs
- Appropriately use GIs in restorative dentistry

Excelente Lecture.
Could Hybrid GIC could be use for nursing bottle caries or Early childhood decay?
Thank you.
Fantastic lecture, fan of your research Dr. Gürgan! Greetings from Peru
Do you use acid etch conditioning to improve adhesion in enamel with GIC´s?
Glass hybrids are used only class 1 or 2 cavities ? and are there different esthetic colour choices in glass hybrids?
can using cavity conditioner make a difference about mikroleakage?
is phosphoric acid used to replace cavity conditioner and applied in a shorter time?
difference between cavity conditioner and dentin conditioner from GC
Is there an issue etching the conventional GIC when trying to layer composite on top
You have a 10-year follow up study with excellent results using Equia Fil. Do you expect to overperform these results with Equia Forte?
After we apply coat how many months will still durable
Cl 5 cervical restorations – material of choice ? and technique of choice ?
thank you for a great talk
Can you please indicate the treatment performed for the tooth tissues in bruxing patients before applying glass hybrids
Thanks Sevil
thank you so much for your valuable presentation
Thank you
Which is better: Equia Forte:Fil or Equia Forte HT? thanks
Thank you for very quality presentation. Glass ionomer restoration include aliminum oksit . İs it any side effect according to studies?
What is surface pretreatment before GI Hyprid Applicatiin?
Do you recommend using GI Hyprid in high stress bearing area ???
Can we perform layering technique using encapsulated GIC and how its done in deep cavities.
A pleuse to ear you. Thanks.from buenos aires
