SDI Riva Self Cure Bulk Fill Glass Hybrid Restorative System

Multiple Scenarios, One Glass Ionomer: Riva SC is the Next Breakthrough

[by Dr. Haleh Fazeli, DDS]

The beauty of dentistry lies in its constant evolution and the fact that no matter how many procedures are completed day after day, challenges inevitably present themselves. 


Every dentist, every patient, every tooth, and every clinical situation is unique. Whether those challenges arise from difficulty in isolation, limited access to the operative field, patient cooperation, or anatomical limitations, clinicians must continually adapt their approach.

One of the most critical factors in successfully managing these challenges is the selection of appropriate dental materials. Choosing the right material for each clinical scenario can significantly reduce stress for the provider, increase efficiency during treatment, and ultimately improve the longevity and success of the restoration.


In situations where isolation and access are compromised, or when treating patients with high-caries risk, glass ionomer materials have long been recognized as a valuable option. Their ability to chemically bond to tooth structure and release fluoride over time makes them particularly useful in these cases. 

However, traditional glass ionomers have often been criticized for their handling characteristics, limited strength, and technique sensitivity. Over the years, advancements in material science have led to significant improvements in glass ionomer technology. These developments have not only enhanced their physical properties but have also made them more user-friendly and suitable for everyday clinical practice.

One such advancement is the next generation of glass ionomer restorative materials exemplified by Riva Self Cure (Riva SC).

Riva SC is a bulk fill glass hybrid restorative system that incorporates ionglass filler technology. 

This filler is composed of a unique blend of ultrafine, highly reactive glass particles of varying sizes. The combination of these particles allows for improved packing, enhanced mechanical properties, and superior handling. As a result, Riva SC demonstrates a very high compressive strength, excellent wear resistance, long-term fluoride release, and increased acid resistance. These features make it a reliable restorative option for a wide range of patients, from pediatric to geriatric populations.


In an independent study conducted in January 2020, the compressive strength and wear resistance of several restorative materials were evaluated. Riva SC demonstrated high compressive strength along with superior wear resistance when compared to other products tested, indicating its ability to withstand long-term masticatory forces.

These characteristics are especially important in posterior restorations and high-stress areas where durability is essential. The Ionglass technology used in Riva SC also plays a critical role in its bioactive properties. 

By oversaturating the minerals within the organic matrix of dentin, the material stimulates biomineralization and promotes the formation of fluorapatite crystals. Fluorapatite is significantly more resistant to acid attack than natural tooth structure, which begins to demineralize at a pH of approximately 5.5. This added resistance provides an additional layer of protection for patients who are at increased risk for bacterial and acidic challenges.

The clinical performance of Riva Self Cure has also been validated by independent evaluators. The Catapult Evaluator Team awarded Riva SC the Catapult Vote of Confidence™, recognizing it as a trusted and reliable glass ionomer restorative material. Notably, 100% of the evaluators stated that they would recommend Riva SC to a colleague. The product consistently met and exceeded expectations for a glass ionomer restorative.

Clinical Application

A clinical case further demonstrates the benefits of Riva SC in a challenging situation. An 87-year-old patient presented with caries on tooth #15 at the distobuccal gingival margin [Figure 1].

The patient still had tooth #16 present, exhibited poor oral hygiene, and had difficulty keeping his mouth open or remaining still for extended periods. Additionally, he could not be reclined into an ideal working position for the provider, making complete isolation nearly impossible. These factors made Riva SC Fast Set an excellent choice for the restoration.


After caries removal and confirmation with a caries indicator, isolation was achieved using cotton rolls and dry angles. Riva Conditioner was then scrubbed into the prepared area using a microbrush for 10 seconds [Figure 2]. 

The area was rinsed and gently dried, ensuring that the tooth surface was not completely desiccated. The Riva SC Fast Set capsule was activated and triturated for 10 seconds before being loaded into the applicator. The material was then injected into the cavity in a single increment [Figure 3].

After waiting 20 seconds, a damp cotton applicator was used to shape the restoration. Once fully set, finishing and polishing were completed using a handpiece and typical finishing burs [Figure 4]. Although a coat of Riva Coat could have been applied and light-cured for 20 seconds, this step was omitted due to the patient’s limited ability to remain open.

Another advantage of Riva SC is its availability in two different viscosity options (regular and high viscosity) each with varying working times and handling behavior. In addition, the wide range of shades allows clinicians to achieve improved aesthetic outcomes. 

This flexibility enables providers to select the option that best suits their clinical situation and personal preferences without compromising the final result. Evaluators consistently highlighted the ease of use, consistency, and bioactivity of Riva SC. Its fluoride-releasing properties and versatility across diverse patient populations make it a dependable and effective restorative material in modern dental practice.

Catapult Vote of Confidence™

Congratulations: SDI Riva Self Cure Bulk Fill Glass Hybrid Restorative System

Evaluators frequently praised the capsule design, ease of handling, adaptability, and overall performance of the material. More than 90% of participants agreed that the instructions were clear and easy to follow, the capsules were simple to use and extruded smoothly, the working time and consistency were well balanced, and the product was safe and easy to handle.

The easy handling and improved aesthetics of Riva SC allow it to be used in a wide variety of clinical scenarios. These include situations with less-than-ideal moisture control, restorations in deciduous teeth, bases and liners, temporary restorations, core build-ups, geriatric restorations, and cervical class V restorations. 

Evaluators repeatedly commented on the material’s excellent balance of flow, adaptability, and strength. Its versatility makes it a valuable addition to the restorative armamentarium. In the December 2020 issue of Clinicians Report, Dr. Gordon J. Christensen recommended Riva Self Cure HV and Riva Light Cure HV, further reinforcing the clinical confidence in this product line.
