  • Anti-osteoclastic drugs and their impact on maxillofacial and orthopedic bone biology, disease, diagnosis, prevention, surgery, and treatment modalities (ARONJ)

    Bisphosphonates (Alendronate, Zolendronate, Pamidronate and others) and additional anti-osteoclastic drugs such as RANKL inhibitors (Denosumab) are among the most prescribed drugs in the world today.

    26 million prescriptions for Alendronate in the US alone are used for treatment of postmenopausal osteoporosis and 250,000 patients with metastatic bone cancer are treated with high dose intravenous bisphosphonates.

    These drugs have been noted to have profound influences on oral and orthopedic health including exacerbation of dental diseases, osteonecrosis of the jaw requiring ablation, spiral fractures of the femur, bone pain, and spinal and other foramenal stenosis These medications have also been associated with a marked decrease in femoral neck fractures, compression fractures of the spine and other osteoporotic fractures such as wrist and humerus.

  • Bisphosphonate-induced Osteonecrosis of the Jaws (BRONJ)
    Bisphosphonate treatment induces cell death in osteoclast populations, slowing bone loss in osteoporosis and impeding the spread of certain cancers (bone metastases), but is also associated with an increased risk of osteonecrosis of the jaw, especially when combined with dental surgery. Bisphosphonate treatment may be received intravenously (94% of BRONJ cases) or orally (6%). These osteonecrotic symptoms have only been observed in the craniofacial region, probably because the local turnover of bone is relatively high; anything that inhibits this normal function will be especially pronounced here.

  • Bone regeneration using tissue engineering and CAD-CAM techonolgy: Their impact on facial bone reconstruction

    Ablative surgery or major facial trauma in the maxillofacial area leads to bone defects that predispose functional as well as aesthetic complications. The bone defects of the facial skeleton need immediate reconstruction to provide satisfactory function of the jaws as well as an acceptable aesthetic outcome. 
    Reconstruction of the maxillofacial area with composite microvascular flaps is challenging and needs a team with experienced surgeons. The surgery is time consuming not only because of the microvascular procedures themselves, but due to demand for optimize intraoperatively the configuration and symmetry of the facial skeleton.

    The development of three-dimensional (3D) computerized modelling in medicine has been rapid during the last years. However, the use of above mentioned CAD-CAM (computer aided design and manufacturing) is still limited. The technology gives tools for surgeons to plan and to train virtually for the surgery, to design, and manufacture the implants needed for the surgery.

    Bone tissue engineering requires several constructive factors. These include among others biocompatible scaffolds and matrices, cells, osteo- and angioinductive growth factors. Modern 3D CAD-CAM technology enables patient-specific scaffold and matrix manufacturing. The scaffold, matrix or implant temporarily replaces the missing part of jaw and allows cells to generate bone accordingly leading to anatomic and symmetrical restoration. Increasing number of studies, both experimental and clinical, are available that show bone regeneration in facial bone defects using CAD-CAM technology, patient-specific matrices and cells.

  • Large Bone Defects
    Large bone defects can complicate osteosynthesis and may lead to fracture nonunion. This project supports effective, innovative solutions to this familiar problem in orthopedic surgery. Current efforts include both in vitro (progenitor cells, vascularization, scaffolds) and in situ (autologous grafts, genetic manipulation, delivery vehicle) approaches.
