Titanium plats are the gold-standard for fracture fixation. Titanium is considered biocompatible, corrosion resistant with an elasticity-modulus closest to bone. Nonetheless, titanium plates are not always as inherent as hoped. The authors investigated morbidity associated with titanium plates in mandibular fractures. A retrospective study of mandibular fractures treated between 2000 and 2018 using internal-fixation was conducted. Data included age, gender, complications, and location. Predictor-variable was location. Outcome-variable was plate removal. A total of 571 patients were included, 107 resulted in plate removal (18.7%). Body was the most prevalent location of fracture (29.3%). Symphysis/para-symphysis showed the highest removal rate (24.1%), followed by body and angle (21.3/19.8%). A total of 23.4% of double-plating cases resulted in plate removal, upper-border in 15% and lower-border in 8.8%, all reconstruction-plates. Exposure was the most frequent complication leading to removal. Although titanium plates are the gold standard, almost every fifth patient returns for plate removal. Agedistribution emphasizing 41 to 50 with decrease towards extremities may imply better healing in the young and soft-tissue elasticity and less complaints in the elderly. Significantly more complications in doubleplating compared to lower border suggests proximity to the oral-cavity as a risk-factor for removal. Complication rates and patterns are not negligible and perhaps should encourage clinicians to consider using biodegradable-systems for upper-border plates.
