Monocortical miniplate fixation placed along 'ideal lines' of the mandible without intermaxillary fixation is the basis of which technique?
- A Champy's technique of functionally stable osteosynthesis ✓
- B Transosseous wiring at the inferior border
- C External pin fixation
- D Reconstruction plating with bicortical screws
Correct answer: A. Champy's technique of functionally stable osteosynthesis
Explanation
Champy described the ideal lines of osteosynthesis along tension zones of the mandible and advocated small monocortical miniplates placed there, allowing early function without intermaxillary fixation. Bicortical lag or reconstruction screws risk injury to the inferior alveolar nerve, which monocortical screws avoid since they engage only the outer cortex. Transosseous wiring and external pins are older, less stable methods now largely historical.
