Internal fixation of fractures.

Area of Science:

• Oral and Maxillofacial Surgery
• Biomechanical Engineering
• Orthopedic Surgery

Background:

• Treatment of mandibular fractures has evolved, incorporating both operative and conservative methods.
• Combined treatment approaches were found to be cumbersome.
• Biomechanical principles are crucial in determining effective fracture fixation strategies.

Purpose of the Study:

• To introduce a novel osteosynthesis plate for functionally stable internal fixation of mandibular fractures.
• To evaluate the indications for lag-screw osteosynthesis in mandibular fracture treatment.
• To explore the advantages of intraoral surgical techniques for mandibular fracture fixation.

Main Methods:

• Development of a new osteosynthesis plate designed for stable internal fixation without additional elements.
• Application of biomechanical principles to identify optimal use cases for lag-screw osteosynthesis.
• Utilizing a combination of tension band plate and lag screw for intraoral surgical procedures.

Main Results:

• The new osteosynthesis plate provides functionally stable internal fixation for mandibular fractures.
• Lag-screw osteosynthesis is indicated for a broader range of mandibular fractures.
• The combined use of tension band plates and lag screws allows for intraoral surgical intervention.

Conclusions:

• The developed osteosynthesis plate simplifies the internal fixation of mandibular fractures.
• Lag-screw osteosynthesis presents expanded indications in mandibular fracture management.
• Intraoral operative fixation of mandibular fractures offers significant patient advantages.
