Screws for KHOURY system (per box of 3 screws) - Meisinger

What is the Meisinger KHOURY system screw?

The KHOURY system screw, manufactured by Hager & Meisinger GmbH, is an osteosynthesis micro-screw designed for the Bone Management® product line. These screws are made of high-quality surgical stainless steel, a material selected to provide optimal stability to transplants despite very small diameters of 1.0 mm or 1.2 mm. This device is specifically developed to meet the requirements of the shell technique (greffe en coffrage), where mechanical maintenance precision is crucial for the success of bone augmentation. They are delivered in boxes of 3 units to meet the needs of specialized oral surgery interventions.

What are the clinical indications for these bone graft screws?

These dental khoury screws are primarily indicated for the secure fixation and stabilization of cortical bone transplants. They are used in the treatment of bone fractures and, more specifically, for the immobilization of transplanted bone blocks during augmentation processes in the oral cavity and the maxillomandibular area. Using the khoury system screw allows the graft to be maintained in a static position, thereby promoting optimal revascularization and bone integration. They integrate perfectly into volumetric reconstruction protocols where hard tissue management requires fine and reliable osteosynthesis.

What are the technical characteristics of these osteosynthesis screws?

The technical characteristics of Meisinger screws are based on their surgical stainless steel design, guaranteeing high mechanical strength for minimal bulk. They are offered in diameters of 1.0 mm and 1.2 mm, allowing for precise handling even in narrow anatomical areas or on thin bone fragments. The manufacturer Hager & Meisinger GmbH specifies that these micro-screws are an integral part of the Micro Screw system. To ensure safe use, the practitioner must respect the maximum recommended rotation speeds during insertion, as summarized in the manufacturer's technical documentation.

What are the contraindications for the use of khoury screws?

The use of the khoury screw is contraindicated in the presence of active infections at the intervention site or nearby, as well as during local or systemic pathological processes such as fever, local inflammation, or abscesses. Furthermore, insufficient bone volume in terms of quality or quantity constitutes an absolute contraindication. Systemic or metabolic pathologies, as well as certain drug treatments leading to progressive bone deterioration (such as taking cortisone, immunosuppressants, bisphosphonates, or unbalanced diabetes), must be rigorously evaluated before any placement of osteosynthesis material.

What are the precautions regarding resorption and removal of the screws?

Unlike resorbable devices, these stainless steel bone graft screws are not intended to remain permanently in the human body. They only provide a temporary support function during the consolidation phase. Once the stabilization function is fulfilled, notably after complete healing of the bone transplant or fracture, the Micro Screws must be entirely removed by the surgeon. Prolonged maintenance beyond the healing phase is not intended by the manufacturer. The practitioner must therefore plan a second-stage intervention for the explantation of these osteosynthesis devices.

Who is the manufacturer and what standards are respected?

These medical devices are manufactured by Hager & Meisinger GmbH, a company based in Neuss, Germany. This product belongs to Class IIb according to current medical device regulations. It carries the CE0044 marking, guaranteeing its compliance with European safety and performance requirements. As a recognized manufacturer in the field of Bone Management®, Meisinger ensures rigorous traceability and manufacturing quality for all of its micro-screw systems. Compliance with sterilization protocols and speed of use recommendations is imperative to maintain the integrity of the device and patient safety.
