Palatal Contourers, 1 large + 1 narrow - Set of 2 (Made in France) - Nichrominox (PN190780) - Delynov

What is the Nichrominox palatal contrastor set?

The Nichrominox palatal contrastor set, referenced under code PN190780, is a set of two specialized accessories for intra-oral imaging. This lot includes a wide model and a narrow model, designed by the manufacturer Nichrominox to adapt to different palatal vault morphologies. These Nichrominox SA devices serve to create an opaque and uniform background, facilitating focus and the reading of anatomical details. Manufactured in France, these instruments are intended for repeated professional use in oral surgery practices, offering a robust solution for the iconographic documentation of clinical cases.

What are the clinical indications for this dental photo accessory?

The use of a palatal photo contrastor is indicated when taking photographs of the maxillary arch in occlusal or frontal views. In implant and periodontal surgery, it allows for the visual detachment of soft tissues and prosthetic components from the rest of the oral cavity. This palatal black background is particularly useful for illustrating the translucency of incisal edges or for documenting the progress of a gingival graft. By using Nichrominox SA products, the practitioner ensures standardization of their shots, which is essential for long-term follow-up and communication with the prosthetic laboratory.

What are the technical characteristics of the PN190780 contrastors?

The palatal contrastors of reference PN190780 are distinguished by their ergonomic design adapted to human anatomy. The set of two pieces covers the needs for adult or pediatric patients thanks to the wide and narrow formats. The surface finish is specifically treated to absorb flash light, thus avoiding parasitic reflections that could alter image quality. This surgery black contrastor is designed by the manufacturer to withstand standard cleaning and sterilization protocols in medical environments, guaranteeing irreproachable hygiene between each patient while maintaining its black background optical properties.

What are the contraindications for the use of these instruments?

There are no absolute medical contraindications to the use of a palatal contrastor, as it is a non-invasive and temporary device. However, its use may be limited in patients with a very marked gag reflex or extremely restricted mouth openings preventing correct positioning of the accessory. These Nichrominox SA instruments should be handled with care to avoid any accidental mucosal trauma during insertion. The practitioner must ensure the integrity of the device's surface before each use; any deep scratch or alteration of the black coating could compromise the quality of the photographic contrast.

What are the maintenance precautions for these non-absorbable devices?

As reusable and non-absorbable CONSO category accessories, Nichrominox contrastors require rigorous maintenance. After each photography session, the devices must be decontaminated, cleaned, and sterilized in accordance with the instructions provided by the manufacturer. It is recommended to use non-corrosive cleaning solutions to preserve the matte appearance of the dental photography black background. Careful drying before autoclave sterilization is recommended to avoid the appearance of lime scale stains that could become visible on the shots. Compliance with these steps guarantees the longevity of the equipment and health safety within the practice.

Who is the manufacturer and what standards are respected?

These contrastors are produced by Nichrominox, a manufacturer recognized for its expertise in instrumentation in France. Although the specific regulatory class and CE marking are not detailed in the current technical data, these products are designed according to French industrial quality standards for the dental sector. As a distributor, Delynov ensures that the Nichrominox SA devices meet the professional requirements of dental surgeons. For any precise information concerning certificates of conformity or ISO standards applied to reference PN190780, it is advised to refer to the technical instructions or the original labeling delivered with the product.
