The Use of 3d Titanium Plates With Two Different Profile Thickness for Open Reduction and Rigid Fixation of Mandibular Parasymphyseal Fracture:Randomised Clinical Trial

The face is the window through which we perceive the world around us, and the world noted us. It serves a crucial role in human interaction and injuries to it result in devastating emotional sequelae. The human face constitutes the first contact point in several human interactions, thus injuries and/or mutilation of the facial structures may have a disastrous influence on the affected person.

The facial area is one of the most frequently injured parts of the body, and the mandible is one of the most commonly fractured maxillofacial bones. For the past decades, there has been a significant increase in maxillofacial traumas involving mandible. They are mainly caused by vehicular accidents, sport activities, penetrating injuries, physical assault, work-related accident, metabolic diseases or tumors.

The position, prominence, anatomic configuration, mobility and less bone support of the mandible make it one of the most frequent facial bones to be fractured. The mandibular fracture accounts for 36% to 54% of all fractures in the maxillofacial region. Mandible is the 10th most fractured bone in the whole body. They may occur alone or in combination with other facial bone fractures.

It plays a major role in mastication, speech, and deglutition. Its fractures result in severe loss of function and disfigurement. Fractures through the mandible at the level of the Symphysis and or parasymphysis are relatively common and account for approximately 20% of mandibular fractures. These fractures are often associated with a second fracture of the mandible, especially in the subcondylar region.

Fractures of the symphyseal region are often associated with the clinical findings of a widened intragonial distance with resultant malocclusion. Fractures of the anterior mandible lack two of the stabilizing factors provided to fractures of the posterior tooth-bearing mandible: the splinting effects of the masseter and internal pterygoid muscles, which form a natural sling, and the interlocking cusps and fossae of bicuspid and molar teeth.
