Miller Bone Rasp #45 with Handle #522 - Hu-Friedy - Delynov

What is the Miller #45 bone file with #522 handle by Hu-Friedy?

The Miller #45 bone file associated with the #522 handle is a manual surgical instrument designed by the manufacturer Hu-Friedy. This device is specifically structured for working on hard tissues in oral surgery. It consists of a serrated working part allowing for controlled abrasive action on the bone and an ergonomic handle referenced as #522 ensuring a stable grip for the practitioner. As a precision instrument, it meets the requirements of clinical practice in implantology and periodontology for the treatment of irregular bone surfaces.

What are the clinical indications for this instrument?

The use of the Miller bone file is indicated in various oral surgery procedures. It is primarily used during alveoloplasty to regularize alveolar ridges after multiple or single extractions. It also allows for the removal of exostoses and the smoothing of sharp bone edges that could compromise soft tissue healing or the comfort of a removable prosthesis. In pre-implant surgery, it helps prepare a harmonious bone bed before the placement of biomaterials or implants.

What are the technical characteristics of the Miller #45 file?

This file is distinguished by its Miller #45 configuration, characterized by an orientation and fineness of serration adapted to sometimes restricted access in posterior or anterior zones. The #522 handle provided by Hu-Friedy offers an optimal balance to transmit the necessary force for filing without excessive fatigue for the surgeon's hand. The instrument's design aims for bidirectional or unidirectional cutting efficiency depending on the given angulation, allowing for progressive and safe bone remodeling.

What are the contraindications for the use of this device?

According to information from the manufacturer Hu-Friedy Mfg. Co., LLC, the use of this instrument is strictly reserved for qualified healthcare professionals. There are no specific medical contraindications listed other than those related to standard surgical protocols. However, the use of the file is contraindicated if the instrument shows signs of wear or corrosion, or if the practitioner has not mastered the manual bone remodeling technique, which could lead to overheating or excessive bone resection.

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

As a reusable and non-resorbable surgical instrument, the Miller bone file must undergo a rigorous sterilization protocol before each intervention. It is imperative to follow the cleaning and disinfection instructions recommended by Hu-Friedy to maintain the integrity of the file's serrations. A visual examination before use is necessary to check for the absence of residual debris in the grooves of the working part. Appropriate lubrication of joints or junction areas may be recommended according to the manufacturer's instructions.
