Gene-activated Matrix for Bone Tissue Repair in Maxillofacial Surgery
Maxillofacial Bone DefectsAlveolar Bone Atrophy5 moreThe purpose of this study is to evaluate safety and efficacy of gene-activated matrix ("Nucleostim") for regeneration of bone tissue in maxillofacial area. Patients with congenital and acquired maxillofacial defects (sockets of extracted teeth, bone defects after injuries, surgeries, excision of benign neoplasms and pseudotumors, etc.) or alveolar bone atrophy will be included into the study.
The Evaluation of Postoperative Antibiotics in Non-Infected Mandible Fractures
Jaw FracturesInfectionThe purpose of the study is to evaluate if postoperative antibiotic use in patients with mandible trauma reduce the risk of postoperative infections and does the benefit differ based on severity, soft tissue loss, other concomitant injuries, and medical problems
Minimally Invasive Dental Occlusion Ties
Jaw FracturesJaw; Fracture4 morePatients sustaining fractures of the upper (maxilla) and/or lower (mandible) jaw may be candidates for the minimally invasive technology evaluated in this study. Patients will be offered standard care including steel jaw wires or the polymer-based "zip tie"-like devices to be studied. Written consent with a full explanation of traditional "jaw wiring" techniques versus this experimental approach will be obtained from the patient. As mandible and maxilla fractures are typically treated under general anesthesia in the operating room, the devices will be applied to the patient's dentition while under general anesthetic. An exception to this will be minimally displaced or easily reduced fractures that can be treated by applying these devices in clinic under topical or local anesthetic. (Of note, wire-based techniques have been used for decades in a clinic-based application for such minimally or easily-reduced fractures.) The devices will allow stabilizing forces to the dental occlusion, achieving a similar function to temporary steel wire techniques ("arch bars"). This will allow the surgeon/principal investigator to treat the fractures with standard techniques such as applying titanium plates applied to the bone with titanium screws (known as "open reduction with internal fixation") or with sustained immobilization for 1-6 weeks (known as "closed reduction"). Note the devices are approved for 3 weeks duration. If treatment requires more than 3 weeks of immobilization, the devices will be removed and new devices re-applied. The experimental devices will be used solely as a replacement for wire-based techniques to achieve an immobile, stable jaw. If for any reason the required forces needed for jaw fracture stabilization are deemed inadequate with the experimental devices, standard steel wire techniques will be employed.
