Intended Use

Artegral HD posterior preformed plastic denture teeth intended use: - Supra construction for combined, fixed removable dental prostheses - Hybrid construction for implant-supported dental prostheses - Cover denture - Total prostheses - Model cast prostheses - Partial dentures

Device Story

Artegral HD are preformed posterior plastic denture teeth used by dental professionals in the fabrication of various dental prostheses. The teeth are constructed from an Interpenetrated Network (IPN) of polymethylmethacrylate (PMMA); the neck utilizes Organic Modified Polymer Network (OMP-N) with added insoluble PMMA spheres; the incisal and dentine portions utilize Highly Modified Polymer-Network (HMP-N) with added amorphous silicon dioxide nanoparticles and fluorapatite. These teeth are integrated into dental prosthetics to restore patient occlusion and aesthetics. They are intended for use in total, partial, implant-supported, and combined fixed/removable dental prostheses. The device provides a durable, biocompatible artificial tooth structure for clinical dental applications.

Clinical Evidence

No clinical data. Substantial equivalence is based on bench testing, including compliance with ISO 22112:2005 (artificial teeth for dental prostheses) and ISO/CD 20795-1 (denture base polymers) for residual methyl methacrylate monomer elution. Biocompatibility testing included USP 29/ISO 10993-5 cytotoxicity, chorioallantoic membrane assay for eye irritancy, and ISO 10993-10 skin sensitization testing.

Technological Characteristics

Materials: PMMA-based Interpenetrated Network (IPN), OMP-N (with PMMA spheres), and HMP-N (with amorphous silicon dioxide nanoparticles and fluorapatite). Standards: ISO 22112:2005, ISO/CD 20795-1, USP 29, ISO 10993-5, ISO 10993-10. Form factor: Preformed posterior denture teeth.

Indications for Use

Indicated for patients requiring dental prostheses, including supra construction for combined fixed/removable prostheses, hybrid implant-supported prostheses, cover dentures, total prostheses, model cast prostheses, and partial dentures.

Regulatory Classification

# Device Name

Proprietary name: artegral HD

Denture teeth Common name:

Classification name: Denture, plastic, teeth (21CFR 872.3590 Product Code ELM)

## Predicate Device

K030588, Merz Dental GmbH artegral and Polystar Selection Denture Plastic Teeth

# Device Description

artegral HD are preformed posterior plastic teeth made from an Interpenetrated artegrair Network (IPN) of polymethymethylmethacrylate (PMMA) with two r orfiner Notwork (1) 100th neck is made from Organic Modified Polymer

{1}------------------------------------------------

Network (OMP-N) and the incisal and dentine portions of the tooth are made from Highly Modified Polymer-Network (HMP-N). OMP-N has added insoluble PMMA spheres, and HMP-N has added amorphous silicon dioxide nanoparticles and fluorapatite. The artegral HD teeth comply with all the requirement of ISO 22112:2005 Dentistry - Artificial teeth for dental prostheses. The additives in artegral HD teeth are known biocompatible materials.

# Intended Use

The artegral HD (high definition) teeth have the same intended use as artegral posterior preformed plastic denture teeth cleared in K030588. As described below, the intended use for artegral HD plastic teeth is described in more detail than the predicate artegral plastic teeth.

Artegral HD posterior preformed plastic denture teeth intended use:

- . Supra construction for combined, fixed removable dental prostheses
- Hybrid construction for . implant-supported dental prostheses
- Cover denture .
- . Total prostheses
- Model cast prostheses ●
- · · Partial dentures

### Technological characteristics and substantial equivalence

The device is comparable in chemical composition to the predicate device.

The device is similar in size, shape, color and usage to the predicate device.

Both the device and the predicate device comply with the physical characteristic requirements of ISO 22112:2005 Dentistry - Artificial teeth for dental prostheses.

# Performance Testing

The artegral HD teeth were tested according to ISO 22112:2005 Dentistry - Artificial teeth for dental prostheses and shown to comply with all the requirements of the standard.

teeth intended use:

Artegral posterior preformed plastic

- Denture teeth .

{2}------------------------------------------------

Test of the artegral HD teeth was performed according to ISO/CD 20795-1 "Dentistry - Base polymers - Part 1: Denture base polymers" (Type 1:Class 1) to judge if there will be a risk from residual methyl methacrylate monomer which can be eluted from the teeth in the oral cavity. The average concentration of residual MMA was well below the limit given in the standard.

Testing for biocompatibility was also performed as follows and all test results were acceptable:

Examination of an Eluate of HMP-N for Cytotoxic Properties in a Cell Culture Test, according to USP 29 and ISO 10993 part 5, Elution Test

Screening for Eye Irritancy Potential of HMP-N in the Chorioallantoic Membrane Assay

Examination of HMP-N in the Skin Sensitization Test in Guinea Pigs According to Magnusson and Kligman (Maximization Test), according to EC method B.6. (96/54/EC), OECD guideline 406 and EN/ISO/DIN 10993-10.2

# Clinical Performance

.

The determination of substantial equivalence is not based on clinical performance data.

## Other Information

No other information was deemed necessary by FDA.

#### Conclusions

artegral HD is substantially equivalent to the predicate device.
