简要总结
The aim of this study is to evaluate clinically and radio-graphically the efficiency of "Tent- Pole "grafting technique for reconstruction of anterior or posterior mandibular ridge defects using synthetic bone graft and Platelet Rich Fibrin (PRF) membrane.
详细描述
Various techniques have been described for the reconstruction of large vertical defects before implant placement . In this study we assessed the efficacy of tenting the periosteum and soft tissue matrix with titanium screws maintaining a space for the graft material in order to augment large vertical defects of mandibular ridge (anterior or posterior region) using data from 12 patients . After 6 months we assessed the increase in bone height and density.

结局指标
主要结局
Radiographic Evaluation for Bone Density using Cone Beam CT
时间窗: 6 months
A Cone Beam Computerized Tomography was obtained to assess the gained bone height \&density.
Pain assessment using Visual Analogue Scale
时间窗: 2 weeks
Pain was assessed through on a 10-point Visual Analogue Scale (VAS). (0-1= None, 2-4= Mild, 5-7= Moderate, 8-10= Severe)
Postoperative edema
时间窗: 2 weeks
Edema was evaluated by its ability to pit.The examiner fingers pressed into dependent area of the patient skin for 5 seconds. The finger sinks into the tissue and leave an impression when they are removed. The pitting was graded on a scale of +1 to +4 as follows: * 1 (trace) slight indentation rapid return to normal. * 2 (mild) the indentation returns to normal in a few seconds. * 3 (moderate) 6 mm indentation rebounds in 10-20 seconds. * 4 (severe) 8 mm indentation rebounds in more than 30 seconds.
