New Screw Design for Securing Buried Distractors Usefulness and Ease of Removal

Abstract

There are 2 types of distraction devices for mandibular distraction: buried and external. The advantage of buried devices is the stability, but the difficulty in removing the screws is the greatest disadvantage. To resolve this problem, an osteosynthesis screw (Farina Screw) has been designed, which greatly facilitates its removal when buried distractors are used.
