Mandibular fractures represent a high percentage of all facial fractures, and the bite force is a fundamental parameter to measure the actual mandibular function and, subsequently, the masticatory efficiency and quality of life. The purpose of the present systematic review was to verify if there is any difference in the bite forces of patients with mandibular fractures fixed by locking or non-locking plates, testing the null hypothesis of no difference in this parameter. A systematic review of the literature was conducted using four databases (PubMed, Virtual Health Library, Web of Science and Science Direct) without restrictions as to publication date or language. We found 3,039 abstracts, and selected 4 articles for this review. The overall results show better performance in bite force for the locking plates when compared with the non-locking plates in the incisor region (mean deviation [MD]: 1.18; 95% confidence interval [95%CI]: 0.13-2.23), right molar region (MD: 4.71; 95%CI: 0.63-8.79) and left molar region (MD: 10.34; 95%CI: 4.55-16.13). Although the results of this study indicated a better bite force result with the locking plates, there is still no sufficient evidence to support this information safely.
下颌骨骨折在所有面部骨折中占比很高，咬合力是衡量下颌骨实际功能的一个基本参数，进而也是衡量咀嚼效率和生活质量的参数。本系统评价的目的是验证采用锁定钢板或非锁定钢板固定的下颌骨骨折患者在咬合力方面是否存在差异，检验该参数无差异的零假设。使用四个数据库（PubMed、虚拟健康图书馆、科学引文索引和科学Direct）对文献进行了系统评价，对出版日期或语言没有限制。我们找到了3039篇摘要，并为本评价选择了4篇文章。总体结果显示，与非锁定钢板相比，锁定钢板在切牙区（平均差值[MD]：1.18；95%置信区间[95%CI]：0.13 - 2.23）、右侧磨牙区（MD：4.71；95%CI：0.63 - 8.79）和左侧磨牙区（MD：10.34；95%CI：4.55 - 16.13）的咬合力表现更好。尽管本研究结果表明锁定钢板的咬合力结果更好，但仍然没有足够的证据安全地支持这一信息。
