简要总结
This study aims to evaluate the clinical and radiographic outcomes of different staged ridge-splitting techniques for management of severely resorbed lower jaws in the posterior region. The study is designed as a clinical trial, so that three different interventions would be compared for a conclusion highlighting the relative best of them.
详细描述
In the context of the care of severely resorbed lower jaws in the posterior region, the purpose of this study is to evaluate the clinical and radiographic outcomes of several stepwise ridge-splitting procedures. The study is supposed to be a clinical trial, with the purpose of comparing three distinct therapies in order to get a result that highlights which of them is the most effective in comparison to the others.

结局指标
主要结局
Alveolar ridge width
时间窗: immediately after implant placement, immediately after implant loading and six months after implant loading
Radiographically via Cone-beam Computed Tomography (CBCT), the width of the alveolar bone was measured horizontally from the buccal to lingual cortex below the crest of the alveolar bone from 3 levels at 1 mm, 3 mm and 6 mm on three cross-sections by the CBCT software (OnDemand, Cybermed Inc, Korea).
次要结局
- Implant stability(immediately after implant placement, immediately after implant loading and six months after implant loading)
