In this study, a 2.5-mm resorbable plating system (Inion CPS, Tampere Finland) was assessed for the fixation of mandibular fractures with 3 weeks of maxillomandibular fixation.
Fifty mandibular fractures in 34 patients (32 males, 2 females) with a mean of 20.8 days of maxillomandibular fixation (MMF) were included in this study. The 2.5-mm resorbable plates were adapted along Champy's line of ideal osteosynthesis and secured with four 8 × 2.5 mm monocortical resorbable screws. All patients were followed for a minimum of 6 weeks with an average long-term follow-up of 10 months. The incidence of soft tissue infection, nonunion, malunion, malocclusion, osteomyelitis, nerve injury, and tooth damage was prospectively assessed.
Primary bone healing was achieved in 100% of cases. Ten minor complications (20%) were observed: 5 soft tissue infections (10%), 4 plate dehiscences (8%), and 1 malocclusion (2%). No evidence of malunion, nonunion, osteomyelitis, plate fracture, or iatrogenic dental or nerve injury was noted; no readmission or reoperation was necessary.
The Inion 2.5-mm resorbable plating system along Champy's line of ideal osteosynthesis plus 3 weeks of MMF is a viable option for the treatment of mandible fractures.
本研究采用 2.5mm 可吸收接骨板系统（芬兰坦佩雷的 Inion CPS）治疗下颌骨骨折，固定 3 周的颌间固定。
本研究共纳入 34 例（32 例男性，2 例女性）50 例下颌骨骨折患者，平均颌间固定时间为 20.8 天。2.5mm 可吸收板沿 Champy 理想接骨线放置，并使用 4 枚 8×2.5mm 皮质可吸收螺钉固定。所有患者均至少随访 6 周，平均随访时间为 10 个月。前瞻性评估软组织感染、骨不连、畸形愈合、咬合不正、骨髓炎、神经损伤和牙齿损伤的发生率。
100%的病例达到了初级骨愈合。观察到 10 例轻微并发症（20%）：5 例软组织感染（10%），4 例接骨板裂开（8%），1 例咬合不正（2%）。未发现畸形愈合、骨不连、骨髓炎、接骨板断裂、医源性牙或神经损伤；无需再次入院或再次手术。
Inion 2.5mm 可吸收接骨板系统沿 Champy 理想接骨线加 3 周颌间固定是治疗下颌骨骨折的一种可行选择。
