Open reduction with internal fixation using plates and screws enhances the stability and correction of anatomic structures, as well as greatly recovering bite force and function. Bite force was recorded on prosthetics on dental implants was 172.5 ± 42.1 N ( 7). In addition to the bite force generated by healthy teeth, there are also studies on bite force in subjects wearing full-mouth removable dentures, in whom the bite force was decreased to 20–40% of the normal value (146.3–149.1 N) after 6 months of adaptation to the denture ( 6). It is noted that 18 years were recorded maximum bite forces ranging from 118 N to 922 N, with a mean of 777.7 ± 78.7 in males and 481.6 ☑90.42 N in females ( 5). on 60 Caucasian subjects with a neutral occlusion, thirty subjects (15 males and 15 females) were aged 15 years and 30 (14 males and 16 females). Therefore, it is essential to study the clinical characteristics of these fractures in order to properly and accurately evaluate them and provide an optimal treatment regime.Īccording to Takaki et al., who evaluated the maximum bite force in 100 Brazilians aged 11–60 with healthy natural teeth, the mean maximum bite force was 285.01 N in men and 253.99 N in women ( 4). Furthermore, midfacial fractures have complicated clinical characteristics, causing severe deformations after the injury, resulting in sequelae such as malocclusion, convex face, displaced eyeballs, or nerve injury ( 2, 3). Because traffic accidents are becoming more and more complex, there is an increasing number of both Le Fort I and Le Fort II fracture cases, and maxillary fracture cases as a whole. According to Phillips et al., there were 1132 cases (16%) diagnosed with Le Fort I fractured and 1305 (19%) Le Fort II fractures in 6989 Le Fort fractures ( 1).
