The maxilla is a paired bone that forms a significant portion of the midface. It articulates with the frontal, zygomatic, palatine bone, and sphenoid bones. The Le Fort I segment, the portion of the maxilla mobilized during the osteotomy, receives its blood supply primarily from the ascending palatine artery (a branch of the facial artery) and the anterior branch of the ascending pharyngeal ...
A Le Fort I osteotomy surgically moves the upper jaw to correct misalignment and deformities. It is used in the treatment for several conditions, including skeletal class II malocclusion, cleft lip and cleft palate, vertical maxillary excess (VME) or deficiency, and some specific types of facial trauma, particularly those affecting the mid-face.
Orthognathic surgery (/ ˌ ɔːr θ ə ɡ ˈ n æ θ ɪ k /), also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and lower face related to structure, growth, airway issues including sleep apnea, TMJ disorders, malocclusion problems primarily arising from skeletal disharmonies, and other orthodontic dental bite problems that cannot ...
Mandibular fracture, also known as fracture of the jaw, is a break through the mandibular bone. In about 60% of cases the break occurs in two places. [ 1 ] It may result in a decreased ability to fully open the mouth. [ 1 ]
A set of three narrow coronoid bones lie above the prearticular bone. As the name implies, the majority of the teeth are attached to the dentary, but there are commonly also teeth on the coronoid bones, and sometimes on the prearticular. [17] Most vertebrates exhibit a simpler scheme, as bones have either fused or vanished.
Six students were taking an intensive workshop at the center last summer, and together they came up with a lead that the bone belonged to Yager. One of the people assisting, Ethan Schwartz, was an ...
An increasingly common strategy to preserve bone and reduce treatment times includes the placement of a dental implant into a recent extraction site. On the one hand, it shortens treatment time and can improve aesthetics because the soft tissue envelope is preserved. On the other hand, implants may have a slightly higher rate of initial failure.
The ambulatory treatment of fractures was the direct result of these innovations. The innovation of the modern cast can be traced to, among others, four military surgeons, Dominique Jean Larrey, Louis Seutin, Antonius Mathijsen, and Nikolai Ivanovich Pirogov. [10] Dominique Jean Larrey (1768–1842) was born in a small town in southern France ...
