Splitter Num D11 Handle Num 30 0.40/23mm - Hu-Friedy - Delynov

What is the Spreader #D11 handle #30 0.40/23mm - Hu-Friedy?

The Spreader #D11 handle #30 0.40/23mm is a manual endodontic instrument developed by the manufacturer Hu-Friedy. This device consists of a tapered working part and an ergonomic #30 type handle. Its structure is specifically designed for the condensation of obturation materials. With a tip diameter of 0.40mm and a useful length of 23mm, this instrument offers balanced rigidity to transmit the necessary force during the canal obturation phase. As a Hu-Friedy brand product, it benefits from a rigorous design meeting the requirements of dental surgeons practicing technical endodontics.

What are the clinical indications for this instrument?

This instrument is primarily indicated during endodontic treatments, specifically for the cold lateral condensation technique. After shaping and cleaning the canal system, the Spreader #D11 is used to push the master gutta-percha cone against the canal walls. This clinical maneuver frees up precise space for the insertion of accessory gutta-percha cones, thereby ensuring optimal apical and coronal sealing. Its use is essential for obtaining a dense three-dimensional obturation, limiting the risks of post-operative bacterial reinfection in conservative dental surgery procedures.

What are the technical characteristics of this device?

The Hu-Friedy Spreader #D11 features precise technical specifications to meet the constraints of root anatomy. It has a tip with a diameter of 0.40mm, which corresponds to an intermediate size suitable for many canals. The length of its working part is 23mm, allowing it to reach the apical zone in most clinical configurations. The number 30 handle ensures a stable grip, reducing muscle fatigue during lateral pressure maneuvers. The thinness of the tip combined with the taper of the instrument allows for deep penetration without exerting excessive stress on the dentinal walls.

What are the contraindications for using the Spreader #D11?

Relative contraindications for the use of the Hu-Friedy Spreader #D11 include clinical situations where the canal anatomy presents extreme curvatures or calcifications that do not allow the safe passage of a 0.40mm instrument without the risk of fracture or the creation of a false canal. Generally, the use of this instrument is contraindicated if the practitioner does not have sufficient visibility or access to control the condensation force exerted. Reference should be made to the indications and contraindications provided by the manufacturer Hu-Friedy to ensure the compatibility of the device with the clinical case being treated.

What are the precautions for use and maintenance?

As a non-resorbable and reusable instrument, the Spreader #D11 requires a strict protocol of cleaning, disinfection, and sterilization between each patient. Before any use, the healthcare professional must carefully read the instructions. It is imperative to visually inspect the 0.40mm tip to detect any signs of wear, twisting, or corrosion that could compromise the integrity of the instrument or patient safety. Excessive pressure during condensation must be avoided to prevent vertical root fractures. This device is exclusively reserved for healthcare professionals qualified in dental surgery and endodontics.
