In craniomaxillofacial (CMF) surgery, precision, stability, and biocompatibility are the foundations of successful bone fixation. Among the diverse range of fixation instruments, CMF self-drilling titanium screws stand out as an indispensable component of modern surgical systems. They simplify surgical procedures, shorten operative time, and ensure stable fixation, making them an essential component in procedures such as maxillofacial trauma repair, orthognathic surgery, and cranial reconstruction.
Key Features and Design Advantages
Self-Drilling Tip Design
The advanced drill-point geometry eliminates the need for pre-drilling, reducing procedure time and minimizing micro-movement during insertion. This feature is particularly useful in delicate areas of the facial skeleton, such as the zygomatic arch, mandible, or orbital rim.
Consistent Insertion Torque
Self-drilling screws provide uniform torque during placement, ensuring optimal fixation strength while preventing over-tightening. This contributes to excellent mechanical stability even in thin or osteoporotic bone.
Superior Biocompatibility of Titanium
Titanium’s natural oxide layer offers remarkable resistance to corrosion and biological degradation. It supports osseointegration, allowing the bone to bond securely with the implant surface.
Variety in Dimensions and Head Designs
CMF screws are available in multiple diameters (commonly 1.5 mm, 2.0 mm, and 2.3 mm) and lengths to suit different anatomical regions. Options like low-profile heads or cross-head recesses provide compatibility with various CMF plates and instruments.
Applications in Maxillofacial Surgery
In maxillofacial surgery, the self-drilling titanium screw plays a crucial role in internal fixation following fractures or osteotomies. Typical applications include:
Mandibular and Maxillary Fracture Fixation:
Used with titanium miniplates or mesh to stabilize fractured segments and promote bone healing.
Orthognathic Surgery (Corrective Jaw Surgery):
Provides rigid fixation after procedures such as Le Fort I, bilateral sagittal split osteotomy (BSSO), and genioplasty.
Zygomatic and Orbital Reconstruction:
Offers reliable fixation in areas with complex bone anatomy, ensuring proper alignment and restoring facial symmetry.
The self-drilling design simplifies screw placement, particularly in restricted surgical spaces where using a drill may increase risk or difficulty. By reducing the need for multiple instruments, surgeons can work faster and with greater precision.
Applications in Cranio-Maxillofacial Reconstruction
Beyond the maxillofacial region, CMF self-drilling titanium screws are also extensively used in cranial reconstruction, such as repairing skull defects, craniotomies, and trauma cases.
In these surgeries, screws are used in combination with titanium meshes, fixation plates, or custom implants to restore cranial contour and protect underlying brain tissue. The low thermal conductivity and biological inertness of titanium make it especially safe for cranial applications.
Some of the most common use cases include:
Cranial flap fixation after craniotomy
Reconstruction of cranial vault defects using titanium mesh
Stabilization in pediatric cranial deformity corrections
The reliability of titanium screws ensures long-term implant retention and reduces the likelihood of postoperative complications.
Clinical Benefits for Surgeons and Patients
Reduced Surgical Time:
Eliminating the drilling step shortens operative time and improves workflow efficiency.
Improved Stability and Healing:
The screw’s strong fixation promotes early bone healing and reduces the risk of non-union.
Minimal Bone Trauma:
The sharp self-drilling tip reduces heat generation and bone micro-fractures, preserving bone vitality.
Enhanced Aesthetic Results:
Low-profile screw heads reduce postoperative irritation, ensuring smoother soft-tissue coverage and better cosmetic outcomes.
