This paper presents experimental results for long-term behavior in externally bonded FRP-strengthened RC slab. Nowadays, the more infrastructures are accelerated deterioration, the more by using FRP material, external bond method is studied and experiment. But there are few study about long-term behavior. So, this paper will be contribute to another study about long-term behavior FRP-strengthened RC slab. For this experiment totally of 3 slabs were produced. One is Control slab and the others are externally bonded FRP-strengthened slab. FRP slab were designed considering same reinforcement ratio for verifying effect of reinforcement according to material.

Purpose: The classic technique for open reduction of subcondylar fractures is the submandibular approach. The aim of this study was to evaluate clinical result of retromandibular approach to displaced subcondylar fractures. Material and methods: During a period of 24months we perfomed a prospective study with a retromandibular approach in 23 paients with displaced subcondylar fractures. In this article we describe clinical result in 23 patients with follow ups for 3 months after surgery. Preoperatively all patients had malocclusion and radiology demonstrated displacement. Result: The retromandibularl approach for ORIF was good in all case. Mouth opening(M/O) was 49mm. Occlusion was good too. Permanent facial nerve palsy was not detected. Conclusion: Our findings indicate that the retromandibular approach is a safe technique for subcondylar fractures.
