Maxillary sinus elevation surgery was developed to increase the height of bone available for implant placement in the posterior maxilla. Should it be compressed in excess, no blood clot is formed and therefore no repair process occurs. As such, the authors have created an up-to-date and accessible resource that every dentist performing sinus augmentation should have on hand for clinical guidance. The maxilla along with the portions of the inferior concha . General considerations . Traditionally, this standard approach is usually conducted at 4-6 months after tooth extraction (standard MSFE). To prevent complications of maxillary sinus grafting, it is . The maxillary sinus (or antrum of Highmore) is the largest of your sinuses. Opening the ostiomeatal complex involves removing the . of the maxillary sinus are 36-45 mm in height, 23-25 mm in width, and 38-45 mm in length (anteroposterior axis).

Clinical Implications: Implants migration through composite graft after maxillary sinus elevation was reported. uncontrolled diabetes). The maxillary sinuses are the largest of the paranasal sinuses, located one on each side as well as totally fill the bodies of the maxillae. Thus, upon reopening Sinusitis responds to medical treatment in the majority of cases, yet occasionally orbital complications may occur due to spread of infection. The orbital floor forms the roof, the alveolar process forms the inferior boundary and the lateral nasal . [1] [2] According to the residual bone height of the posterior maxilla, the sample was divided into three . Clinical significance: Sinusitis may cause headache and facial pain, and in this case, intramaxillary pressure change is one of the main mechanisms causing this sinogenic headache or facial pain . Sinusitis is important in clinical dental practice because one of the symptoms of maxillary sinusitis is pain that can mimic pain of dental origin (odontogenic maxillary sinusitis).10 When a patient is complaining of maxillary posterior tooth pain, it is incumbent on the dentist to differentiate between pain of odontogenic origin and pain from the maxillary sinus.
