Superior Adult Silicone Contrastor (Made in France) - Nichrominox (PN190777) - Delynov

What is the Nichrominox adult upper silicone contrastor?

The adult upper silicone contrastor is a clinical photography accessory developed by Nichrominox SA. This device, identified under reference PN190777, is specifically designed to adapt to the morphology of the upper arch of adult patients. Manufactured in France, it consists of a flexible plate whose opaque surface provides a dark, homogeneous background. Using a silicone upper contrastor is essential for eliminating visual distractions such as the tongue or cheeks during image acquisition. Its silicone design offers an alternative to rigid metal models, aiming to improve comfort during placement in the mouth while ensuring optimal opacity for the photographic sensor.

What are the clinical indications for this black dental contrastor?

This upper dental contrastor is indicated for all aesthetic dentistry, implantology, and orthodontic follow-up procedures requiring high-precision photographic documentation. In oral surgery, it highlights incisal contours and cervical margins by creating a sharp contrast with dental structures. The silicone black background helps the practitioner capture details of translucency and enamel characterization without chromatic interference from soft tissues. It is particularly used during pre-implant assessments or to validate the aesthetic integration of prostheses on the upper arch. Its systematic use standardizes clinical shots, thereby facilitating communication with the prosthetic laboratory and long-term follow-up of complex cases.

What are the technical characteristics of the PN190777 upper photo contrastor?

The upper photo contrastor, bearing technical reference PN190777, is distinguished by its French manufacturing by Nichrominox SA. Its main feature lies in the use of silicone as the constituent material, offering structural flexibility that facilitates handling inside the oral cavity. Unlike rigid devices, this model can be slightly adjusted to fit the palatal vault without generating excessive pressure. Its deep black shade is designed to absorb flash light, thus avoiding unwanted reflections that could alter the image reading. The dimensions are specifically calibrated for adult morphology, covering the entire field of vision required for an occlusal or frontal view of the upper arch, ensuring a professional result and increased sharpness of the free edges.

What are the contraindications for using this silicone device?

Although the manufacturer Nichrominox SA does not list specific medical contraindications in the provided data, the use of this device must be evaluated by the practitioner based on the clinical situation. As with any accessory introduced into the mouth, particular attention should be paid to patients with increased sensitivity to silicone materials or a severe gag reflex. The product should not be used if it shows signs of surface degradation or tears that could compromise hygiene or the integrity of the operative field. The practitioner must ensure that the positioning of the contrastor does not obstruct the patient's airway during photography. In the absence of specific MDR data, it is recommended to systematically refer to the instructions for use provided by the manufacturer.

What are the maintenance precautions for this non-resorbable contrastor?

As a reusable and non-resorbable photography accessory, maintaining asepsis is an absolute priority. The practitioner must strictly follow the cleaning and disinfection protocols recommended by Nichrominox SA for silicone devices. After each use, the contrastor must be cleared of organic residues before undergoing an appropriate sterilization cycle. It is crucial to check the compatibility of disinfection solutions with silicone to avoid any whitening or loss of opacity of the material, which would impair its function as a black dental contrastor. Adequate storage, protected from dust and permanent creases, will extend the product's lifespan and ensure consistent visual quality during future clinical photography sessions.

Who is the manufacturer and what standards does the product meet?

The product is manufactured by Nichrominox SA, a company recognized for its expertise in designing accessories and devices for dental practices, based in France. Regarding regulatory certifications such as risk class or specific CE marking, this information is not explicitly detailed in the current technical documentation. However, as an established French manufacturer, Nichrominox SA subjects its production processes to the quality requirements in force for medical photography accessories. It is the responsibility of the healthcare professional to verify the device's compliance with their facility's protocols and to consult the product labeling to confirm safety standards and specific reprocessing instructions before any clinical implementation.
