Basic and patient-oriented researchComparison of Titanium and Biodegradable Miniplates for Fixation of Mandibular Fractures
Section snippets
Patients and Methods
The present study involved 91 patients (65 males and 26 females) with mandibular fractures who had undergone open reduction at the Department of Oral and Maxillofacial Surgery, Chosun University Hospital from May 2005 to August 2007. The patient age range was 11 to 69 years (mean 28.4). The fractures consisted of 34 cases of symphysis fracture, 23 of mandibular angle fracture, 13 of symphysis fracture accompanied by mandibular condylar fracture, and 21 of concurrent mandibular angle fracture
Results
A titanium metal plate was applied in 43 patients (in the median area in 33 fractures and the mandibular angle in 23 fractures). An absorbable plate was applied in a total of 48 patients (in the median area in 35 fractures and the mandibular angle in 21 fractures; Table 1). The postoperative complications included 3 cases of infection and 1 fracture of a fixation plate for an overall incidence of complications of 4.41%. All the complications that developed in the patients who had received
Discussion
Persistent attempts have been made to develop equipment that can minimize complications by fixing the bone fragments after fracture or osteotomy and induce solid bone union with stabilized fixation. The requirements for such a bone fixation device include sufficient strength and rigidity to induce bony union, the absence of a tendency to produce a foreign body reaction or infection within the body, no interference with the bony union, an inability to be palpated or visualized, and spontaneous

2020, International Journal of Oral and Maxillofacial SurgeryCitation Excerpt :The screw diameter ranged from 1.3 mm to 2.0 mm with corresponding plates, depending on the location of the fracture. The most frequently used biodegradable osteosynthesis systems were the Inion CPS (79/15/6 poly-l-lactic acid (PLLA)/poly-dl-lactic acid (PDLLA)/trimethylene carbonate)2,11,14,33,35,36,44,46,47 and the BioSorb FX (self-reinforced 70/30 PLLA/PDLLA)38,41,42,46,51 (Supplementary Material Table S4). The screw diameters ranged from 1.5 mm to 2.5 mm; these were generally larger compared to the titanium systems for similar fracture types.

2018, Journal of Cranio-Maxillofacial SurgeryCitation Excerpt :Even now, several clinicians are reluctant to use bioabsorbable devices for mandibular fractures because of their low strength and rigidity to induce bony union and material-related complications (Eppley, 2005; Alkan et al., 2007). However, with an increase in the material strength of bioabsorbable plates, more studies are demonstrating that metallic and resorbable plate systems do not differ significantly, even when used for high load-bearing sites such as the mandible (Lee et al., 2010), osteotomies (van Bakelen et al., 2014), and reconstructions (Kim et al., 2015). In the present study, we demonstrated that there were no differences in postoperative stability and fracture healing, assessed by the evaluation of postoperative occlusal changes and comparison of immediate postoperative CBCT images with 3-month postoperative CBCT images, between the bioabsorbable plate and titanium miniplate groups.
