Introducing Stela – The Future of Composites


Stela is an innovative high-performance self-cure composite.

Stela offers an unlimited depth of cure and low-stress polymerisation with a gap-free interface. There is no need to acid etch or light cure.

Stela achieves its ground-breaking properties through a tailored combination of BPA-free resin monomers, optimised ionglass™ fillers (SDI’s bioactive proprietary hybrid glass), and specially surface-modified amorphous silica. Stela’s outstanding mechanical properties come from a rapid curing reaction. The Stela monomers form polymeric chains and, simultaneously, these chains are rapidly and densely cross-linked to each other, forming a complex web that strongly binds the ionglass™ filler and the amorphous silica, resulting in a strong and resilient restorative material.

The Stela snap set fast cure is due to an innovative hydroperoxide-based initiation system that is free of tertiary amine. This ensures fast-setting characteristics, good colour stability and an excellent conversion rate.

Once cured, Stela’s matrix delivers consistent and reliable strength and durability for all restorations. The simple two step process minimises operator errors and patient sensitivity with no etch or curing lights required. Stela is the solution for all your clinical needs

Stela is available in two delivery systems: Stela Capsule and Stela Automix syringe.

Fewer Steps, Fewer Fail

Stela Primer revolutionises the etch, prime and bond system, while delivering a better bond strength.

While other etch, prime and bond systems require up to 7 steps and 90-120 seconds to complete, the Stela Primer system is complete in only two steps and 15 seconds. Fewer steps means fewer opportunities for errors and longer lasting restorations.

Reduce your in-chair time and eliminate potential technique sensitivity with the simplified Stela technique.

Faster With Chameleon Aesthetics

A 50% Faster Self Cure

Stela has a faster self cure setting time than two other leading restoratives. Stela Capsule and Stela Automix syringe both offer a comfortable working time of ≥ 1 minute and 30 seconds. Restorations are ready for finishing and polishing in 4 minutes from the start of the mixing time.

This 50% time saving increases your treatment efficiency. Such efficiency is multiplied when restoring multiple cavities consecutively.

Translucency & Opacity

A bulk fill composite generally has opacity limitations to allow light to penetrate more deeply.

Stela does not need a curing light and offers a balance between translucency and opacity for most posterior teeth. Its universal shade with chameleon effect blends in with surrounding structures, blocking stains like a dentine replacement and sealing edges for a flawless finish that mimics enamel.

Stela offers an unlimited depth of cure without compromising aesthetics.

Truly An Amalgam Alternative

An “Amalgam Alternative” Is A Bold Claim. Is It True?

Many products claim to be an amalgam alternative, but fail comparisons based on strength, marginal sealing and depth of cure. Stela has been formulated specifically as a restorative that can be used as an amalgam alternative, with the advantage of having a lifelike aesthetic result in a cavity without mechanical retentions. Stela is available in a universal shade that blends to surrounding tooth areas with a chameleon effect.

Snapset Strength In Minutes

Restoratives harden over time until they reach their final strength. Stela is formulated to reach a high strength as quickly as possible, allowing finishing and polishing in just 4 minutes. After this initial set, Stela becomes a strong composite that easily exceeds the properties of alternatives.

While amalgam achieves only 37% of its final strength in 60 minutes, Stela achieves 90% strength in the same 60 minute period.

Stela’s snapset strength reduces premature failures during the critical first 24 hour period, decreasing patient returns and re-work.

Stela also offers great value. One capsule of Stela has more volume than a 3-spill amalgam capsule, which is enough for large restorations.
