Epidemiological data shows that maxillofacial defects are most common among young people of working age.
The most common defects of this area are fractures that are caused by high energy trauma (accidents, sport injuries, industrial injuries, etc.).
Not so common defects include deformities and defects caused by various illnesses.
Deformation of facial skeletal bones distorts the patient’s facial proportions and may compromise the stomatognathic system, visual and olfactory systems, the function of the lower jaw.
In clinical practice for maxillofacial reconstruction, bone grafts, bone cement and standard implants (meshes, plates and screws, augments) used are traditionally shaped manually (bent and cut), either preoperatively or intraoperatively.
However, with these materials, it is difficult to restore the aesthetic of the face and evenly fill the defects, which may lead to irregular healing of the bone and unsatisfying aesthetic results.
Patient-specific maxillofacial reconstructive implants solve these problems
Therefore, in case of large maxillofacial defects and in order to restore the patient’s aesthetic and decrease the risk of infections and other complications, it is recommended to use patient-specific maxillofacial reconstruction implants that are manufactured individually for each patient with regard to the patient’s anatomy, pathology and the requirements for the design of the implant defined by the surgeon.
Manufacturing patient-specific maxillofacial reconstruction implants includes conventional bone cement (PMMA) and silicone materials as well as the following materials: titanium, titanium alloys (Ti6Al4V, Ti6Al4V-ELI), polymeric materials (PHDPE, PEEK and PEKK) and bioceramics.
3D printing gives implants added value because it has almost no limitations in the realization of the most complex geometries and enables forming trabecular metal surfaces that ensure better secondary fixation of the implant.
Comparison of materials used for patient-specific maxillofacial reconstruction implants.
Material Advantages Disadvantages Titanium and titanium alloys Great osteointegration Can be made with lattice structure Great strength properties Mechanically stable 3D printed Radiopaque Stiff Cost+ Polymers: PEEK (polyether-ether-ketone), PEKK (polyether-ketone-ketone) Radiolucent Elasticity Bone like properties Light weight 3D printed No interaction with bone Only small sample clinical studies Cost++ Bioceramics Bone like structure Radiolucency Great osteointegration Can be 3D printed Cost +++ Only small sample clinical studies Shatter Material Combination Various properties may be obtained depending on the surgeon’s requirements and individual patient’s case No clinical studies or small sample clinical studies The designs for patient-specific maxillofacial reconstruction implants are only limited by the surgeon’s imagination and the patient’s aesthetic needs.
Patient-specific maxillofacial reconstruction implants are manufactured individually for each patient with regard to the patient’s anatomy, pathology and the requirements of the treating surgeon for the design, fixation solutions and materials used.
They are designed on a personalized maxillofacial anatomical model that is recreated from computer tomography scan images.
Therefore, a patient-specific implant suits the patient’s anatomy perfectly and evenly fills the defects thus aesthetically restoring the maxillofacial shape and symmetry, and using patient-specific surgical guides ensures accuracy of implant positioning and insertion.
Clinical indications for Ortho Baltic patient-specific maxillofacial reconstruction implants.
Ortho Baltic manufactures patient-specific maxillofacial reconstruction implants for the following clinical conditions and their combinations: Defects of the integrity of maxillofacial areas may be caused by the following: Acquired or congenital deformities of the bone tissue as well as deformities as a consequence of disorders that affect the bone tissue;.
Complications of implants, bone grafts;.
Oncological maxillofacial defects;.
Other structural changes of the bone tissue.
Manufacturing and materials for patient-specific maxillofacial reconstruction implants.
All the materials, software and hardware used to manufacture patient-specific maxillofacial reconstruction implants and surgical guides are certified: patient-specific maxillofacial reconstruction implants are manufactured using additive manufacturing technology DMLS from medical grade titanium alloy Ti6Al4V;.
Single-use patient-specific surgical guides, patient-specific anatomical and implant models used in presurgical planning as well as for planning and training purposes during surgeries are printed from biocompatible polymer (PA 2200, also known as Nylon-12), using additive manufacturing technology SLS.
Detailed information about patient-specific implant design, manufacture and validation process are available.
If you prefer to use a different material than Ti6Al4V
please contact us.
