Oral and Maxillofacial SurgerySynthetic monofilament sutures are preferred for their smooth surface, which reduces the risk of infection by preventing bacteria from being trapped in the suture material, thus promoting better healing outcomes.

ProsthodonticsExplanation: Natural dentition can typically withstand average biting forces of around 600N, which is significantly higher than the 110N that complete dentures can generally handle. Complete dentures rely on muscular and bony support and are limited by the resiliency of the soft tissues in the oral cavity.

Oral PathologyCrouzon syndrome is characterized by early synostosis of cranial sutures (craniosynostosis), maxillary hypoplasia, and a prominent nose resembling a "parrot beak." This syndrome is caused by mutations in FGFR2 gene leading to premature fusion of skull sutures, resulting in characteristic facial features including proptosis, hypertelorism, and midface retrusion. Treacher Collins affects mandibulofacial development, Pierre-Robin involves micrognathia, and Marie-Sainton is cleidocranial dysplasia.

Oral SurgeryDiplopia, or double vision, can occur due to various types of facial fractures, particularly those involving the zygomaticomaxillary complex (ZMC). Fractures in this area can lead to muscle entrapment or damage to the extraocular muscles, resulting in misalignment of the eyes and subsequent diplopia. The ZMC is a critical area for the stability of the orbit and the surrounding structures, making it a common site for such complications.
