Superior Double L and S Silicone Contrastor (Made in France) - Nichrominox (PN190774) - Delynov

What is the upper double L and S silicone contrastor?

The upper double L and S silicone contrastor, referenced under code PN190774 at Delynov, is an instrument specifically designed for intra-oral photography. Manufactured in France by Nichrominox for the Nichrominox SA, this device stands out for its silicone structure, offering an alternative to traditional rigid models. Its dual-ended design (sizes L and S) allows it to adapt to different upper arch morphologies. This flexible photo contrastor is used to create an opaque, dark background, highlighting the anatomical details of the teeth and soft tissues without unwanted reflections. Its soft texture improves patient comfort during placement in the mouth by the practitioner or assistant.

What are the clinical indications for this Nichrominox accessory?

In oral surgery, implantology, and aesthetic dentistry, this flexible dental contrastor is indicated for high-precision photographic assessments. It is particularly useful when taking frontal or occlusal shots to document the initial state, surgical steps, or final result of an implant placement or gingival graft. By creating a sharp black photo silicone background, it allows for a better appreciation of the translucency of the incisal edges and the transition line between the prosthesis and the gingiva. The use of this product distributed by Delynov also facilitates communication with the prosthetic laboratory by providing high-contrast images where shades and shapes are perfectly isolated from the oral environment.

What are the technical characteristics of this photo contrastor?

The PN190774 dental silicone contrastor features technical characteristics focused on clinical handling. Its silicone composition gives it significant flexibility properties, allowing the instrument to be slightly curved to adjust to the oral cavity without causing trauma to the mucous membranes. This double model (L and S) offers two working widths on a single instrument, thus optimizing office inventory. The surface is treated to be completely matte, which is crucial for absorbing flash light and avoiding overexposed areas in photos. Although sterilization specifications are not detailed in the source data, this type of Nichrominox equipment for the Nichrominox SA is generally designed to meet the hygiene requirements of dental practices.

What are the contraindications for the use of this device?

There are no major listed medical contraindications for the use of a silicone dental photo contrastor outside of standard asepsis protocols. However, the practitioner must ensure the absence of any known patient allergy to silicone components before insertion into the mouth. The device must not be used if its surface shows alterations, tears, or deep scratches that could harbor microorganisms or modify the visual rendering of the shots. Like any instrument introduced into the oral cavity, recommended cleaning and disinfection protocols from the manufacturer must be followed to avoid any risk of cross-contamination between patients.

What are the maintenance precautions for this autoclavable contrastor?

To maintain the optical properties and flexibility of the Nichrominox SA silicone contrastor, rigorous maintenance is necessary. Although the term autoclavable dental contrastor is often associated with this Nichrominox range, it is imperative to refer to the manufacturer's specific instructions regarding temperature cycles and decontamination products compatible with silicone. Gentle manual cleaning with a non-abrasive solution is recommended to avoid polishing the matte surface, which would create reflections during future use. After each sterilization cycle, the instrument must be inspected to verify that it retains its structural integrity and deep black color, thus guaranteeing the constant quality of the clinical iconography.

Who is the manufacturer and what standards are met?

The upper double L and S silicone contrastor is manufactured in France by Nichrominox, a manufacturer recognized for its expertise in instrumentation and sterilization accessories. This product is marketed under the brand Nichrominox SA and distributed by Delynov. Although the regulatory class and specific CE marking are not mentioned in the provided technical documentation, Nichrominox applies rigorous manufacturing standards for its devices intended for healthcare professionals.
