NEW STANDARDS FOR OMF SURGERY
Immediate bonding with the bone, less invasive implant fixation, and reduced surgical time.
BoneWelding® technology sets a new and superior standard for orthopedic implants: superior primary stability due to immediate bonding with the bone, less invasive implant fixation, and reduced surgical time. The BoneWelding® process employs gentle ultrasonic energy to induce controlled melting of pre-defined, polymeric implant components.
The pins are fused both into bone and to the plate using ultrasonic energy. Only monocortical fixation is needed, so tooth roots and blood vessels can be protected. Implantation of the pins takes only a few seconds and the polymer will set immediately. The plates are used in non-load-bearing fracture stabilization.

PREDRILLING
This picture illustrates the pilot hole, created using a specified BoneWelding® drill bit. This is easily done by drilling through a preformed hole in the resorbable plate.
IMPLANTATION WITH ULTRASOUND
Gentle pressure on the handpiece, together with ultrasonic vibration through the sonotrode, push the thermoplastic implant into the pre-drilled hole in the bone. This sets up shearing forces at the contact surfaces between the bone and polymer, causing small amounts of polymer to liquefy.
IMMEDIATE STABILISATION
The liquid polymer flows into the trabecular tissue structure, immediately solidifying, which provides a mechanically stable bond to the bone and to the plate after only a few seconds.
DEGRADATION OF
BONEWELDING® PIN
Only minimal inflammatory reaction during the degradation process without fibrous tissue formation at the bone-polymer interface.
The implants are completely absorbed within 12-24 months and eventually degrade into water and C02. Histopathological studies prove that the short ultrasonic pulse and the local melting of the polymer have no thermal side effects to the surrounding tissues.

RESORB PIN AND PLATE SYSTEM
The VetWelding Resorb pins and plates are made of 100% biocompatible and fully bioresorbable Poly-D,L-lactic Acid (PDLLA). The in vivo degradation of the pins and plates is based on the natural physiological process of hydrolysis, which results in a complete metabolization of the polymer into H2O and CO2.
PINS AND PLATES
The pins are 1.6 and 2.1 mm in diameter and available in lengths from 4 mm to 9 mm. Plates and meshes are provided in a vast variety of different shapes and sizes, and can be easily contoured or cut with scissors intraoperatively. This ensures the right implant for every indication and easy adaption to patient specific anatomy.
BONEWELDING®
ULTRASONIC GENERATOR
The BoneWelding® ultrasonic generator and handpiece control the ultrasonic energy needed for BoneWelding® implants. The BoneWelder® Vet ultrasonic generator and handpiece are designed for VetWelding implants.
ESSENTIAL TOOLS
Handpiece and Sonotrode: The sonotrode (handpiece tip) is mounted on the handpiece. It transmits ultrasonic energy to the BoneWelding® implants.
