Device Story

Llis and Vittra APS are radiopaque, light-curing composite resins for dental restorations. Vittra APS utilizes an Advanced Polymerization System (APS), a combination of photoinitiators that enhance curing capacity under various light-curing units and reduce shade/opacity shifts during polymerization. Vittra APS contains zirconia complex filler particles (200nm average size, 72-82% weight load) and is free of Bis-GMA and Bis-EMA. Llis uses methacrylate monomers, silanes, and fillers. Used in dental clinics by professionals for direct/indirect restorations, core build-ups, and splinting. The material is applied in increments, light-cured, and polished. Benefits include improved aesthetics, mechanical strength, and ease of polishing. The device is stored at 5-30°C.

Clinical Evidence

Bench testing only. Evaluated per ISO 4049 and ISO 10993-1. Tests included depth of cure, color stability, radiopacity, flexural strength, water sorption/solubility, Knoop hardness, conversion rate, elasticity module, compressive strength, and fracture toughness. Accelerated and long-term stability studies confirmed a 3-year shelf life. Comparative studies against recognized commercial composites (Estelite Quick, Filtek Z350 XT, Tetric N-Ceram) demonstrated Vittra APS performance is statistically equal or superior in mechanical and aesthetic metrics.

Technological Characteristics

Light-curing, radiopaque, methacrylate-based composite resin. Vittra APS: zirconia complex fillers (200nm, 72-82% wt load), Bis-GMA/Bis-EMA free. APS photoinitiator system. ISO 4049 and ISO 10993-1 compliant. Form factor: syringe/capsule. Storage: 5-30°C. Shelf life: 3 years. Polymerization: light-curing unit (>=450mW/cm2, 400-500nm).

Indications for Use

Indicated for direct and indirect dental restorations in anterior and posterior teeth, core build-ups, splinting, veneers, deciduous teeth restoration, diastema closure, tooth shape modification, fragment cementation, and porcelain/composite repairs in all patient populations.

### G) Device Description

#### Llis

Llis is a radiopaque composite for anterior and posterior restorations. Its composition was based in modern concepts so that methacrylate monomers, silanes and fillers with adequate size distribution were combined to produce a product with differentiated physical, mechanical and optical properties. Llis presents a simplified shade system, offering enamel, dentin and incisal shades.

### Vittra APS

Vittra APS is a highly aesthetic light-curing composite resin recommended for restorations of all classes in anterior and posterior teeth. The composite is radiopaque; its loading particles are composed by spheres of a zirconia complex with average load particle size of 200nm, with total inorganic load of 72% to 82% in weight (52% to 60% in volume). Those characteristics contribute to enhance both mechanical and aesthetic properties, especially evidenced by how easy it is to obtain proper polishing and by the long-lasting surface shining. Vittra APS' formula is free of Bis-GMA and Bis-EMA, following the present trend of products free of Bisphenol A (BPA).

APS is the acronym for Advanced Polymerization System, and it consists of a combination of different photoinitiators that interact among each other amplifying the curing capacity of light emitted from light-curing units. Added to different materials, the system provides different advantages.

In the case of Vittra APS, APS adds as main benefit the reduction or elimination of visual shade and opacity alteration before/after light curing, which enhances the predictability of the result. Another factor is that, although there is very little concentration of camphorquinone - that has a yellowish aspect - APS has great power of polymerization allowing greater degree of conversion. The APS system is activated by any type of lightcuring unit available on the market, even those with less power or narrow range of wavelength.

Thus, there is no<br>difference between the samples. | All results are within the range<br>specified by ISO 4049. | ATTACHMENT 09 –<br>SENSITIVITY TO<br>ENVIRONMENT<br>LIGHTING |
| Depth of Cure - ISO<br>4049 | According to ISO 4049, the<br>specification for this material is that its<br>curing depth is: > 1.0 mm for opaque<br>materials and > 1.5 mm for non-<br>opaque materials. | All results are greater than the<br>specified threshold, therefore<br>the material is considered to<br>be in conformity. | ATTACHMENT 10 –<br>DEPTH OF CURE |
