Device Story
IDODENTINE is a hot-cured PMMA polymer blank (disc or block) used as an intermediate material for fabricating custom dental prostheses. Input: CAD/CAM milling system data; Transformation: subtractive milling of the polymer blank into specific dental shapes; Output: temporary crowns, bridges, implant-supported restorations, denture bases, or bite splints. Used in dental laboratories or clinical settings by dentists or dental technicians. The device provides a biocompatible, temporary restorative solution; clinical benefit derived from the ability to create patient-specific provisional structures via digital workflows.
Clinical Evidence
No clinical data. Bench testing only. Performance verified via ISO 10477, ISO 20795, and ISO 22112 standards. Biocompatibility confirmed per ISO 10993-5 (non-cytotoxic). Physical testing (flexural strength, water absorption/solubility, residual monomer) demonstrates equivalence to predicate device.
Technological Characteristics
Material: Hot-cured Polymethylmethacrylate (PMMA). Form factor: Circular discs or rectangular blocks. Processing: CAD/CAM milling. Standards: ISO 10477 (crown/bridge), ISO 20795 (dentures), ISO 22112 (polymer teeth), ISO 10993-5 (biocompatibility). Connectivity: None (standalone material).
Indications for Use
Indicated for patients requiring temporary anterior/posterior crowns, bridges (up to two adjacent pontics), implant-supported temporary restorations, removable denture bases, or therapeutic bite/occlusal splints. Maximum usage period is 12 months.
Regulatory Classification
Identification
A temporary crown and bridge resin is a device composed of a material, such as polymethylmethacrylate, intended to make a temporary prosthesis, such as a crown or bridge, for use until a permanent restoration is fabricated.

## 5- Devices description
Dental polymer blank is a circular solid (disc) or rectangular solid (block) of PMMA with or without post attachment for use in a Cad-controlled milling machine for production of provisional restorative prostheses such as dental crowns and bridges and removable dental structures. These blanks are available in a variety of shapes for different milling systems and are also available in variety of dental shades.
Dental polymer blanks are made with the same material (Hot cured PMMA) that is used for the manufacture of the Union Dental artificial teeth brands ODILUX and ODIPAL (K070591). These polymer discs or blocks are especially suited for creating dental structures by means of milling CAD/CAM techniques commonly used in the dental laboratories and in dental practice. The elaboration is designed by a professional, a dental technician or a dentist. This quarantees their correct use, since it is an intermediate product in order to manufacture a custom-made product.
#### 6- Intended use
Acrylic polymer blank particularly suitable for making removable or temporary dental structures such as crowns and bridges using milling technology using CAD/CAM.
#### Indications:
- Temporary anterior and posterior crowns -
- -Temporary anterior and posterior bridges with up to two adjacent pontics
- Implant supported temporary restorations -Maximum recommended usage period: 12 months
- Removable structures for dentures (dental bases) -
- Removable structures for therapeutic restorations (bite splints or occlusal splints) -
#### 7- Technological characteristic and substantial equivalence

device has similar chemical cocomposition as as the predicate The device. (Polymethylmetacrilate, commonly named as PMMA, the same PMMA that is used for produce acrylic teeth)
#### Technological characteristics:
The device has the same technological characteristics as the predicate device (Hot cured PMMA). And the device is similar in sizes, shapes and color scale as the above predicate devices. (Variable thickness milling blank (Disc or block) in Vita colours (A1, A2...), or pink or clear)
Properties:
The device has comparable physical and chemical properties as the predicate device. (Meeting the requirements of ISO standards for the polymer-based dental materials, ISO 10477, 20795, 22112)
Usage:
The device has similar indications for use as the sum of the predicate devices: Milling blank in the fabrication of temporary restorative dental prostheses such as dental crowns and bridges M-PM-DISC (Tooth colored) or removable dental structures like denture bases M-PM-DISC (Pink) and bite splints M-PM-DISC (Clear).

Below the flower, the text "unidesa-odi" is visible in a small, sans-serif font, suggesting it may be a logo or watermark associated with the image.
## 8- Materials
Polymers based on PMMA are well established products; these products have been used as an established part of dental prosthesis techniques for over 70 years. UNION DENTAL S.A. has been manufactured this type of polymers since its foundation in 1965.
Dental polymer blanks (the subject device and predicate devices) are made with the same (powder / liguid) mix that is used for the manufacture of artificial teeth (Hot cured PMMA) and all the components of these products had been suitably considered in the bibliography. PMMA is biocompatible for this intended use.
### 9- Preclinical testing and standards
#### Clinical and Non clinical performance
ldodentine dental polymer blank has not been tested clinically. Both Idodentine and predicate devices are fabricated from the same PMMA that is used for produce acrylic teeth. This PMMA has been tested for biocompatibility and physical properties (see the biocompatibility and non -clinical testing section).
This PMMA used has been rated as biocompatible and Non toxic and this PMMA material also met the applicable requirements of ISO 10447(crown & bridges material), ISO 20795(removable dentures) and ISO 22112(polymer teeth) standards.
The subject device has passed testing according to ISO 10477/2004: DENTISTRY - POLYMER-CROWN AND BRIDGE MATERIALS. This international standard specifies BASED the classification, requirements and test methods for the polymer-based crown and bridge materials. The subject device also has passed testing according to ISO 10993-5 and has been rated as Non cytotoxic

#### Comparison table:
#### Discussion of the nonclinical test submitted:
Both subject device and predicate device meet the requirements of applicable ISO standards and the results of the non-clinical testing are so similar between the device and the predicate that, taking account the error percentages of the measures and possible differences in test method(as is the case of monomer content where ISO 20795 standard allows to use different ways to calculate the final result(GC, HPLC...), we can speak about predicate and device have similar results in the non clinical testing.

Image /page/6/Picture/0 description: The image shows a close-up of a white daisy with a yellow center. The background is a blurry mix of blue and white, creating a soft, dreamy effect. The words "unidesa-odi" are written in a small, sans-serif font at the bottom of the image.
The tests discussed above indicate that the subject device is substantially equivalent in to the predicate device.
## 10-Conclusions
The new and predicate devices are similar in function, and similar in composition, production technology and intended use. This supports that the applicant device is substantially equivalent to the predicate device.
