Subsequently, maxillomandibular advancement was used for patients with obstructive sleep apnea. Currently, maxillomandibular advancement surgery is often performed simultaneously with genioglossus advancement (tongue ...
Following surgery, patients may require up to six weeks of rest before they are able to return to the demands of their daily life. [6] As all patients heal slightly differently, ORIF may result in a less-than-ideal correction of facial bones, resulting in poor occlusion or facial asymmetries. Furthermore, as with any surgery, ORIF comes with ...
Orthopedic plates are designed based on the bone fracture. While the general design is similar, each plate must be manufactured to not only to reduce the fracture but also fit the contour of the patient's bone. [5] Protection Locking plates can be used either to support a locking head screw, or to force bone together at the fracture.
A healing abutment passes through the mucosa, and the surrounding mucosa is adapted around it. A cover screw is flush with the surface of the dental implant, and is designed to be completely covered by mucosa. After an integration period, a second surgery is required to reflect the mucosa and place a healing abutment. [39]: 190–1
