Comparative evaluation of bite force analytical study following mandibular osteosysthesis using three-dimensional and...

Area of Science:

• Oral and Maxillofacial Surgery
• Biomaterials Engineering
• Orthopedic Surgery

Background:

• Mandibular fractures pose significant challenges in achieving stable osteosynthesis.
• Conventional titanium miniplates are widely used, but their efficacy in restoring full masticatory function requires further investigation.

Purpose of the Study:

• To compare the effectiveness of 2 mm three-dimensional (3D) titanium miniplates versus 2 mm conventional titanium miniplates in mandibular fracture osteosynthesis.
• To evaluate the impact of these fixation methods on bite force recovery.

Main Methods:

• A randomized study involving 40 patients (age 20-40) with mandibular fractures.
• Patients were divided into two groups: Group A (20 patients) received 3D titanium miniplates, and Group B (20 patients) received conventional titanium miniplates.
• Bite force was measured at incisor, right molar, and left molar regions at 1, 3, 6, and 8 weeks post-surgery.

Main Results:

• Bite force values increased progressively in both groups, nearing those of healthy individuals by 8 weeks.
• A significant difference in bite force change was observed between the 3D and conventional miniplate groups at incisor and molar regions.
• 3D miniplates required less surgical exposure and minimal soft tissue traction.

Conclusions:

• Three-dimensional (3D) titanium miniplates are effective for mandibular fracture osteosynthesis, demonstrating superior bite force restoration.
• 3D miniplates offer advantages of greater stability, increased bite force, reduced implant material, and enhanced 3D stability.
• These findings suggest 3D miniplates may be a preferred option for managing mandibular fractures.
