Silicone Palatal Double L & S Contrastor (Made in France) - Nichrominox (PN190783) - Delynov

What is the Nichrominox double L & S silicone palatal contrastor?

The double L & S silicone palatal contrastor, referenced under code PN190783 by the manufacturer Nichrominox for the brand Nichrominox SA, is an instrument dedicated to clinical photography. This silicone palatal contrastor is distinguished by its silicone design, offering a flexible texture for patient comfort while ensuring total opacity. Its double-ended structure, featuring Large (L) and Small (S) sizes, allows it to adapt to the different arch morphologies encountered in the practice. As a black palatal contrastor, it serves to eliminate distracting visual background elements, such as the tongue or soft tissues, in order to highlight dental details with optimal sharpness.

What are the clinical indications for this black photo contrastor?

The use of this black photo contrastor is indicated in all clinical documentation procedures requiring precise analysis of dental anatomy. In oral surgery and implantology, it allows for the documentation of the initial state or post-operative results by creating a flexible dental black background that accentuates contrasts. It is particularly useful for capturing incisal translucencies, enamel characterizations, and prosthetic preparation limits. This device helps the practitioner obtain standardized shots for patient follow-up, communication with the prosthetic laboratory, or presentation of clinical cases, by perfectly isolating the palatal arch.

What are the technical characteristics of model PN190783?

The model PN190783 from the brand Nichrominox SA presents specific technical characteristics for intra-oral photography. Its French manufacturing by the manufacturer Nichrominox ensures a rigorous design. This silicone contrastor features a double end (L & S), offering versatility of use according to the width of the patient's palatal vault. The nature of the silicone used allows for a dental photo contrastor that does not reflect flash light, thus avoiding visual artifacts on photographs. Its flexibility facilitates its positioning in the mouth while maintaining sufficient rigidity to remain stable during the shot, guaranteeing a uniform and matte background.

What are the contraindications for the use of this device?

There are no documented specific medical contraindications for the use of this silicone palatal contrastor other than known sensitivities to silicone materials. However, its use may be limited by extremely reduced mouth openings or severe gag reflexes in certain patients during palatal positioning. As with any instrument introduced into the oral cavity, the integrity of the device should be checked before each use. The practitioner must ensure that the contrastor is correctly positioned to avoid injuring the soft tissues. For any additional information on safety of use, it is recommended to refer to the instructions provided by the manufacturer Nichrominox.

What are the maintenance and durability precautions?

The silicone palatal contrastor from the brand Nichrominox SA must be handled with care to preserve its optical properties. Although the material is designed to withstand standard cleaning cycles in a clinical setting, it is essential to follow the decontamination and sterilization protocols recommended by the manufacturer for silicone devices. The use of abrasive cleaning agents that could alter the matte surface of the black photo contrastor must be avoided, as any scratch or modification of the surface state could generate unwanted reflections during future shots. Appropriate dust-free storage after treatment helps maintain the quality of the black background necessary for high-precision dental photography.
