Device Story

Opus Bulk Fill APS and Opus Bulk Fill Flow APS are light-curing, radio-opaque composite resin materials used by dental professionals in clinics. The APS (Advanced Polymerization System) utilizes a combination of photo-initiators to amplify curing capacity when exposed to light-curing units. The APS version allows for 5mm increments in posterior restorations; the Flow version allows for 4mm increments for base/lining and minimally invasive procedures. These materials are applied directly to teeth to restore structure, repair defects, or build up cores. The output is a hardened, tooth-colored resin restoration. Benefits include reduced restoration time due to bulk-fill capability and improved clinical efficiency. The device is non-reusable and intended for permanent use.

Clinical Evidence

Bench testing only. Performance evaluated per ISO 4049, including depth of cure, flexural strength, water sorption, solubility, radiopacity, color stability, and filler particle size distribution. All results met specified thresholds. Accelerated stability studies confirmed shelf-life.

Technological Characteristics

Light-curing composite resin; APS (Advanced Polymerization System) photo-initiator technology. Supplied in syringes or capsules. Complies with ISO 4049 (restorative materials) and ISO 10993-1 (biocompatibility). Non-sterile, single-use. Storage 5-27°C.

Indications for Use

surface (it does not require an additional capping layer). The composite has approximately 79% of load filler (in mass).

APS is the acronym for Advanced Polymerization System, and it consists of a combination of different photo initiators that interact among each other amplifying the curing capacity of light emitted from light-curing units.

#### Opus Bulk Fill Flow APS

Opus Bulk Fill Flow is a bulk-fill flowable light-curing composite (fluid) recommended to be used as base and lining of restorations on posterior teeth. That feature associated to its cure depth – due to the composite's translucency – allows Opus Bulk Fill Flow to be applied in increments of up to 4mm, reducing the time for restoring large cavities.

| Depth of Cure -<br>ISO 4049 | According to ISO 4049, the specification<br>for this material is that its curing depth is:<br>> 1.0 mm for opaque materials and > 1.5<br>mm for non-opaque materials. | All results are greater than the specified<br>threshold, therefore the material is<br>considered to be in conformity. |
| Colour tone<br>stability after<br>radiation and<br>water<br>absorption - ISO<br>4049 and ISO<br>7491 | The acceptance must be performed<br>provided that there is no more than a small<br>change in colour, it must be proven as<br>follows: | All comparisons were carried out by<br>three observers with normal eyesight<br>(Tiago Vicente, Josley Habinzeureuter<br>and Simone Brasil Carvalho), certified<br>by a competent physician. They did not<br>attest to any color difference in the<br>samples analyzed. |
| | a)comparisons should be made by visual<br>inspection and analysed by three<br>observers with normal vision, who do not<br>identify any differences in colour, this<br>comparison must be carried at a distance<br>of 200 to 300 mm for a period of no more<br>than 2 seconds; | |
| | b)perform the comparison cited in a) in a<br>light chamber at Day Light - D65 mode; | The results demonstrate that the<br>product meets ISO 4049. |
| | c)perform the comparison in paragraph a),<br>by placing the specimen on a diffuse white<br>background of 90% approximate<br>reflectance, and it should have as a<br>limiting size the size of the specimen,<br>which must be surrounded by a grey<br>background with a diffuse reflectance of 30<br>± 5%. | |
| Radiopacity<br>ISO 4049 | Compare the individual optical drives of<br>each aluminium scale against the density<br>of each scale (this check must be<br>performed using ISO 4049 as reference).<br>Get the value of the optical density/grey<br>value for the δs thickness of the specimen<br>and determine the corresponding value of<br>aluminium, δа. | The values found in the specimens are<br>between the second and third scale of<br>the aluminum part, proving that the<br>material is radiolucent according to the<br>requirements of ISO 4049 |
| Flexing<br>Resistance - ISO<br>4049 | According to the EN ISO 4049 standard the<br>specification for flexural strength is<br>≥50MPa. | All results are greater than the specified<br>threshold, therefore the material is<br>considered as conformant. |
| Water sorption<br>and solubility.<br>- ISO 4049 | Sorption: Maximum of 40 µm/mm3.<br>Solubility: maximum of 7.5 µm/mm3. | The results demonstrate that the<br>product complies the specification in<br>the EN ISO 4049 Standard. |
| Accelerated<br>Stability Studies | Study created to accelerate the possible<br>chemical degradation and/or physical<br>changes of the product in forced conditions<br>of storage. | Considering the results observed at the<br>end of the 149 days test period, the<br>shelf-life of 2 years in the storage<br>condition of 27 °C for the product can<br>be confirmed. |
| Evaluation<br>Report Of Long- | Study designed to verify the physical and<br>chemical characteristics of the product<br>during the expected shelf life. The results | We don't have any conclusive data<br>about shelf life yet. At the moment we<br>are using the estimated shelf life in 2 |
| Term Stability<br>(Shelf) | are used to confirm the expiration date<br>and storage conditions. | years in the storage condition of 27 ° C,<br>based on no accelerated stability test. |
| Filler particle<br>size<br>distribution<br>(microns) | Study designed to verify the grainsize<br>analysis and optical characteristics. | The test results demonstrate the<br>microns within the specifications. |
