AI Article Synopsis
- This study evaluated the effectiveness of bioabsorbable internal fixation devices on maxillary Lefort I fractures using biomechanical analysis and 3D modeling.
- It revealed that the fixation with two bioabsorbable plates was unstable, while zygomaticomaxillary pillar fixation proved to be more stable.
- The findings suggest that the stability of fracture fixation is affected by molar occlusion, enhancing the understanding of bioabsorbable materials in dental applications.
Article Abstract
The aim of this study was to apply biomechanical analysis model to evaluate the effects of bioabsorbable internal fixation devices on maxillary Lefort Ι fracture. CT scan technology and the finite element software (ansys) were used to establish three-dimensional finite element models of five resorbable internal fixation devices in maxillary Lefort Ι fractures. We used the model to calculate the stress of the upper jaw and internal fixation. We further analyzed the stability of fixation under four occlusions. The fixation using two bioabsorbable plates was not stable. The zygomaticomaxillary pillars fixation is more stable than other fixations. The stability of fracture fixation was influenced with the molar occlusion. The current study developed a functional three-dimensional finite element model of bioabsorbable internal fixation and compared the stability of five fixation methods for maxillary Lefort Ι fractures. The results would facilitate the application of bioabsorbable materials in dental clinic.

Background: Arthroscopy can be used to assist the open reduction internal fixation (ORIF) approach in the treatment of acute ankle fractures. Arthroscopy can also help to assess the articular surface but is performed in only 1% of ankle fracture cases.
Purpose: We aimed to investigate (1) whether arthroscopy-assisted ORIF (AORIF) would lead to improved postoperative functional outcomes compared to conventional ORIF and (2) whether differences in postoperative complication rates exist between these 2 techniques.
