An oroantral fistula (OAF) is an epithelialized oroantral communication (OAC), which refers to an abnormal connection between the oral cavity and the antrum. [1] The creation of an OAC is most commonly due to the extraction of a maxillary tooth (typically a maxillary first molar) which is closely related to the antral floor.
The palatal lift however, is used when there is not enough palatal movement. It raises the palate and reduces the range of movement necessary to provide adequate closure to separate the nasal cavity from the oral cavity. Speech bulbs and palatal lifts aid in velopharyngeal closure and do not obturate a fistula. A speech bulb, yet another type ...
Oral–antral communication [ edit ] A variant of the Valsalva maneuver is used to aid diagnosis of oral–antral communication, i.e., the existence of a connection between the oral cavity and the maxillary sinus .
Oro-antral fistula if associated with sinusitis. [7] Acute Bacterial Rhinosinusitis. Though it is indicated only in severe cases not as a regular treatment. [8] It can be also used as diagnostic procedure for: Carrying out culture and sensitivity test if the returning fluid is mucopurulent or purulent in Chronic Sinusitis. [9]
Alveolar cleft grafting is used primarily to allow the eruption of the maxillary canines into the mouth between the ages of 8 and 13 years old. It is also used to close oranasal fistulas, stop fluid reflux into the nose, improve speech, support the maxillary lateral teeth, and stabilize the jaw for orthodontics or orthognathic surgery.
X-ray showing a sinus lift in the left upper jaw Sinus lift surgery, 3D Illustration. Maxillary sinus floor augmentation [1] (also known as a sinus lift, sinus graft, sinus augmentation, or sinus procedure) is a surgical procedure that aims to increase the amount of bone in the posterior maxilla, in the area of the premolar and molar teeth by lifting the lower sinus membrane and placing a bone ...
Static occlusion refers to contact between teeth when the jaw is closed and stationary, while dynamic occlusion refers to occlusal contacts made when the jaw is moving. [ 1 ] The masticatory system also involves the periodontium , the TMJ (and other skeletal components) and the neuromusculature, therefore the tooth contacts should not be looked ...
Oromandibular dystonia is characterized by involuntary spasms of the tongue, jaw, and mouth muscles that result in bruxism, or grinding of the teeth, and jaw closure. These conditions frequently lead to secondary dental wear as well as temporomandibular joint syndrome. In addition, problems with chewing, speaking, and swallowing may result from ...
