The Schneider membrane is the mucosa that covers the inner part of the maxillary sinus cavities. The free surface is a ciliated pseudostratified epithelium, while the deeper portion is a highly vascularized connective tissue.
The stromal fraction, bordering the bony wall of the sinus, after tooth loss can exhibit increased osteoclastic activity resulting in resorption of the bone in the posterior maxilla.
The aims of this study were to compare the responses of human maxilla and frontal bones under 30 degrees-oriented impacts. Maxilla and frontal bones of the same subject were impacted by a guided horizontal steel cylinder.
Linear acceleration time histories and force time histories were plotted and corridors were proposed for maxilla bone response.
The amount of resorbed bone is different in the anterior and posterior part of maxillary bone. This is influenced by growth of maxillary sinus in the posterior part of maxilla and bone resorption from both sides - sinus and oral lumens, mainly in edentulous patients.
A maxilla bone is a facial bone that is located above the lower jaw and below the orbits. It is also known as a 'moustache' bone and it consists of two separate bones that fuse together to form the maxilla.
The function of a maxilla bone is to protect the face, hold the top half of the teeth in place and support the floor of the nose.
