Aim And Objective: The present study compared the stability of fracture fragments in the management of bilateral parasymphysis mandible fracture with Miniplate fixation and Reconstruction plate fixation using finite element analysis.
Material And Method: 3D FE Mandible model was created using CT scanner. Two bilateral parasymphysis mandible fracture models were created. Model 1 was fixed with Miniplates, and Model 2 was fixed with Reconstruction plate. Loading forces of 120 N at molar region and 62.5 N at incisor region were applied. These two models were imported to ANSY'S Workbench Software.
Result: Miniplate fixation model showed comparatively reduced gap between fragments than Reconstruction plate. But the gap values of both the models were within the physiologic limit of healing under this specific loading. Analytically Miniplates were superior to Reconstruction plate in the management of bilateral parasymphysis fracture.
Conclusion: Analytically Miniplates are superior to Reconstruction plate in the management of bilateral parasymphysis fracture. As the masticatory forces were reduced during fracture healing period, both fixations provide satisfactory healing. So both Miniplate and Reconstruction plate can be considered as fixation method for bilateral parasymphysis mandible fracture.

Soft robots and bioinspired systems have revolutionized robot design by incorporating flexibility and deformable materials inspired by nature's ingenious designs. Similar to many robotic applications, sensing and perception are paramount to enable soft robots to adeptly navigate the unpredictable real world, ensuring safe interactions with both humans and the environment. Despite recent progress, soft robot sensorization still faces significant challenges due to the virtual infinite degrees of freedom of the system and the need for efficient computational models capable of estimating valuable information from sensor data.

Canine acanthomatous ameloblastoma (CAA) is an invasive benign epithelial odontogenic tumour most commonly affecting the mandible of large breed dogs. To the author's knowledge, this report describes the first computer-aided design patient-specific implant (PSI) that has been placed for a critical sized bone defect in mandibular reconstruction of a dog in the UK. The aim was to restore mandibular stability using a regenerative approach combining a titanium locking plate and compression-resistant matrix infused with recombinant human bone morphogenetic protein-2 (rhBMP-2) to bridge the 85 mm mandibular defect created by a segmental mandibulectomy.

Background: The articulotrochanteric distance (ATD) has universally been utilized to assess greater trochanter overgrowth in pediatric orthopaedic diseases. However, its overgrowth cannot be detected in a timely manner due to the absence of a normal ATD value. This study is to determine the ATD normal value in hip radiographs of children under the age of 14 and to establish the threshold for overgrowth of the greater trochanter.

This case report describes the reconstruction of a rostral maxillary defect by two custom-made titanium implants following a rostral partial maxillectomy for treatment of squamous cell carcinoma (SCC) in a seven-year-old dog. An incisional biopsy and CT scan were performed to establish the diagnosis, to plan possible surgery, and to assess the margins of the tumour. The patient had no radiographic signs of metastasis at the time of diagnosis.
