Bone-Spreader Osteotome #4 convex max 4.2mm - Hu-Friedy - Delynov

What is the Bone-Spreader #4 convex osteotome max 4.2mm - Hu-Friedy?

The Bone-Spreader #4 designed by Hu-Friedy is a manual surgical instrument used in implantology for bone manipulation. This device is characterized by a convex-shaped tip with a maximum diameter reaching 4.2mm. Manufactured by Hu-Friedy Mfg. Co., LLC, this instrument is specifically structured to meet the requirements of dental surgeons during the implant site preparation phases. Its design allows for precise mechanical action on the bone tissue, thus facilitating the subsequent steps of implant placement. As a Class I device, it meets the quality standards required for professional dental instrumentation.

What are the clinical indications for the dental bone spreader?

The dental bone spreader is primarily indicated for ridge expansion and bone condensation procedures. In implant surgery, this convex osteotome is used to progressively widen a narrow alveolar ridge without removing bone material, thus preserving vascularization and available volume. It is particularly useful in type III or IV bone, where it allows for compacting bone trabeculae against the walls of the osteotomy, thereby increasing local density and improving primary implant stability. Its use is strictly reserved for healthcare professionals trained in oral surgery and implantology techniques.

What are the technical characteristics of this convex osteotome?

This Hu-Friedy instrument features precise technical specifications for bone surgery. Its working part is of the convex type, a geometry specifically chosen to promote lateral expansion while minimizing the risk of apical perforation. The maximum diameter is calibrated at 4.2mm, which corresponds to the final or intermediate stage of preparation depending on the chosen implant diameter. The technical reference indicates a robust design suitable for the moderate percussion forces required during insertion. This device belongs to the category of durable consumables (CONSO) for the dental office, ensuring smooth integration into standard sterilization protocols.

What are the contraindications for the use of this instrument?

Contraindications related to the use of the Hu-Friedy Bone-Spreader #4 osteotome include all clinical situations where mechanical bone expansion is prohibited. This specifically concerns areas with excessive bone density (type I) where the risk of cortical fracture is high, or cases of extreme bone resorption that do not allow for safe manipulation. According to data from the manufacturer Hu-Friedy Mfg. Co., LLC, use is strictly reserved for healthcare professionals. It is imperative to consult the instructions for use to identify specific warnings related to the patient's physiological state or systemic pathologies that could compromise bone healing.

What are the maintenance and handling precautions?

As a non-resorbable Class I instrument, precautions mainly concern maintaining the integrity of the 4.2mm convex tip and sterility. Before each use, the practitioner must inspect the instrument to ensure the absence of deformation or corrosion. Although specific material details are not provided, Hu-Friedy instruments must be cleaned, disinfected, and sterilized in accordance with current dental surgery protocols. Particular attention must be paid during handling to avoid any impact on the active tip, which could alter the precision of the dental bone spreader during its insertion into the implant site.

Who is the manufacturer and what standards are met?
