Grater for bones Miller number 21 with handle number 522 - Hu-Friedy - Delynov

What is the Miller #21 bone file handle #522 - Hu-Friedy?

The Miller #21 bone file from the Hu-Friedy brand is a manual surgical instrument specifically designed for bone work in the oral environment. This model consists of an active Miller #21 working part mounted on an ergonomic handle referenced #522. Manufactured by Hu-Friedy Mfg. Co., LLC, this instrument belongs to the category of bone surgery instruments. Its structure is optimized to offer a stable grip during smoothing gestures, allowing the practitioner to precisely control the force applied to mineralized tissues. As a Class I medical device, it meets the basic regulatory requirements for non-invasive or reusable surgical instrumentation according to current directives.

What are the clinical indications for this dental miller bone file?

The use of the Miller #21 dental bone file is indicated during various oral and implant surgery procedures. Its main function is the regularization of alveolar ridges after multiple or single extractions in order to eliminate bone irregularities and spicules that could hinder healing or the placement of a prosthesis. It is also used during alveoloplasty procedures to smooth sharp bone edges. In pre-implant surgery, it allows for the preparation of the recipient site by refining the modeling of the autogenous bone. This instrument is strictly reserved for qualified healthcare professionals, such as dental surgeons, stomatologists, and implantologists, trained in hard tissue manipulation techniques.

What are the technical characteristics of this instrument?

The Miller #21 bone file is distinguished by its technical configuration combining a specific working end and a #522 type handle. The design by Hu-Friedy ensures a robust junction between the active part and the handle, guaranteeing efficient transmission of the back-and-forth movement necessary for bone smoothing. Although specific materials are not detailed in the source documentation, the manufacturing standards of Hu-Friedy Mfg. Co., LLC guarantee an instrument suitable for the sterilization cycles required in a dental office. Its geometry is designed to access sometimes narrow alveolar areas while maintaining constant cutting efficiency on cortical or cancellous bone surfaces.

What are the contraindications for the use of the Miller #21 bone file?

According to information from the manufacturer Hu-Friedy, contraindications are related to the intended use and general safety warnings. The use of this instrument is prohibited for any personnel who are not a duly trained healthcare professional. Clinically, the use of the file may be contraindicated in situations where the structural integrity of the bone is too compromised or in the presence of specific bone pathologies that do not allow for mechanical manipulation. It is imperative to refer to the instructions for use provided by Hu-friedy 3232 N. Rockwell St. Chicago, Il 60618 USA before any intervention. Failure to comply with cleaning and sterilization protocols also constitutes a major contraindication to its reuse on a patient.

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

As a reusable surgical instrument and not a resorbable device, the Miller #21 bone file requires a rigorous maintenance protocol. After each use in oral surgery, the instrument must undergo a complete cycle of decontamination, manual or ultrasonic cleaning, and sterilization. It is crucial to visually inspect the condition of the Miller #21 working part to detect any wear of the file's ridges, as a loss of sharpness can impair the effectiveness of bone smoothing and increase operative time. The manufacturer Hu-Friedy recommends reading the instructions carefully to guarantee the longevity of the instrument and maintain its initial technical performance, thus avoiding any corrosion or premature degradation of the #522 handle.
